Provedor de dados: 32
Autores: Rojas Rojas, Patricia.
El psílido de la papa [Bactericera cockerelli (Sulc)] es una de las plagas más importantes de las solanáceas, causa daños no sólo por la alimentación sino además por el papel como vector de enfermedades en papa y tomate, lo cual ocasiona pérdidas millonarias en Estados Unidos de América, México y Centroamérica. Debido a esto el uso de plaguicidas contra este insecto se ha incrementado, y con ello los posibles problemas de resistencia a insecticidas, brotes de plagas secundarias y daños al ambiente; entonces es necesario implementar un programa de manejo integrado de esta plaga, donde el control biológico se convierta en una de las herramientas principales, para ello es necesario incrementar el conocimiento de la biología de los enemigos naturales de este...

Physicochemical and nutritional alterations induced by two-spotted spider mite infestation on strawberry plants
Provedor de dados: 69
Autores: Livinali,Emanuele; Sperotto,Raul Antonio; Ferla,Noeli Juarez; Souza,Claucia Fernanda Volken de.
Background Strawberry is a pseudofruit mainly cultivated in temperate climate regions. Considering its high levels of ascorbic acid and phenolic compounds, the consumption of strawberry fruit can be beneficial to health. The Brazilian strawberry production revolves around 3000 tons per year, significantly influencing the food market and generating income to farmers. However, this production can be partially impaired by two-spotted spider mite (TSSM) Tetranychus urticae Koch infestations, due to decreases in the quality and quantity of fruit. Since there are no data in the literature about alterations caused by TSSM infestation in strawberry plants, our work aimed towards evaluating nutritional and physicochemical parameters of TSSM-infested strawberry...

Autores: Pratissoli,Dirceu; Polanczyk,Ricardo A; Holtz,Anderson M; Dalvi,Leandro P; Silva,Alexandre F; Silva,Luciano N.
Biological characteristics of the egg parasitoids Trichogramma acacioi, T. atopovirilia, and T. bennetti were studied to select the one with better performance on the control of the Diamondback moth, Plutella xylostella. Parasitism rate, viability, and sex ratio were studied. Parasitism rate ranged from 1.67 to 41.33%. T. atopovirilia and T. acacioi were respectively the most and less aggressive species. The viability ranged from 6.20% for T. acacioi to 53.34% for T. atopovirilia. There were no differences on sex ratio (p&lt;0.05) that remained above 0,88. T. atopovirilia was the species with best performance in the laboratory when rearing on the Diamondback moth eggs.

Capacidade reprodutiva de fêmeas de Apanteles galleriae (Hymenoptera, Braconidae) em lagartas de Galleria mellonella e Achroia grisella (Lepidoptera, Pyralidae) criadas com dietas diferentes
Provedor de dados: 76
Autores: Zacarin,Giuliano Grici; Gobbi,Nivar; Chaud-Netto,José.
The reproductive capacity of females of Apanteles galleriae (Wilkinson, 1932) was evaluated in fifth instar caterpillars of Galleria mellonella (Linnaeus, 1758) and Achroia grisella (Fabricius, 1754) fed on standard diet and diets enriched with protein. The reproductive capacity of parasitoid females on fifth instar caterpillars of G. mellonella and A. grisella with variable weight was also evaluated. The host weight interfered in the sex ratio of the obtained parasitoids. In heavier caterpillars, the investment in female descendants was greater than in males, and in lighter caterpillars the inverse occurred.

Autores: Giri,Federico; Collins,Pablo.
The predator-prey relationship of Palaemonetes argentinus Nobili, 1901 and Culex pipiens s.l. larvae was studied under laboratory conditions. The prawns were separated in two groups, isolated and grouped ones. Mosquitoe larvae were offered to prawns in two forms, limited and unlimited offer to both groups. In the first analysis, values of predation did not differ significantly between males and females of P. argentinus. Predation in 24 h was 14,9 ± 4,2 larvae/prawn. A reduction of predation was observed with unlimited offer for the same hour, during all the experiment. Predation with unlimited offer was higher on the first day than on the second, but returned to high values on the third day, for both groups. In the grouped experiment, predation with...

A mosca-dos-chifres Haematobia irritans L. 1758 é uma importante praga da bovinocultura. Seus danos são causados pelas picadas dolorosas que provocam prurido nos animais, irritação subcutânea, lesões devido às cabeçadas e acidentes mais graves ocasionados pelo agrupamento doa animais, principalmente dos jovens e debilitados. As lesões constituem uma porta de entrada para instalação de miíases ou infecções bacterianas. os animais atacados deixam de se alimentar adequadamente, refugiando-se nas matas, reduzindo consequentemente a produção de leite, carne e atividade reprodutiva, principalmente com relação aos touros. No manejo integrado desta praga, os criadores deverão utilizar métodos de controle eficientes, com a finalidade de reduzir ao máximo sua...

Controle de qualidade na produção massal de Trichogramma pretiosum, 1879 (Hymenoptera: Trichogramatidae).
Provedor de dados: 14
Autores: ALMEIDA, R. P. de.
O controle biológico de insetos-praga se constitui em uma das táticas mais importante do manejo integrado de pragas, visto que, além de poder ser utilizado em consonância com todos os demais métodos de controle, é ambientalmente seguro e sem risco para saúde humana. Sua eficiência, em condições naturais, nem sempre é alcançada devido as baixas taxas de ocorrência, quando comparada às pragas. Por isso, na maioria das situações, necessário se faz utilizar inimigos naturais produzidos de forma artificial, em biofábricas, possibilitando sua liberação em grandes áreas de cultivo do algodoeiro. Um dos gêneros de parasitoide mais utilizados no mundo como agente de controle biológico é denominado de Trichogramma (Hymenoptera: Trichogrammatidae). Sua aplicação é...

O fungo Cylindrosporium sp., ate o momento, nao foi cultivado em meio de cultura, no entanto, os conidios retirados de crostas colonizadas, quando aplicados em jardim clonal atacado por Phyllachora uberi, propiciaram ao Cylindrosporium uma taxa de colonizacao de aproximadamente 45% das crostas, o que pode ser representativo em termos de reducao do inoculo primario na area. Todavia, acredita-se que esse parasito podera tornar-se importante para o controle do inoculo primario de P. huberi, principalmente se seu cultivo in vitro for viabilizado. Verificou-se tambem que Cylindrosporium sp. pode disseminar-se rapidamente em jardim clonal atacado por P. huberi.

Chrysodeixis includens (Walker, 1858) (Lepidoptera: Noctuidae) tem sido considerada uma praga severa em lavouras como a soja e o algodão, espécies de grande importância econômica para o Brasil. Inseticidas à base de baculovírus, um grupo de vírus patogênicos a insetos, têm sido usados com sucesso para controlar lepidópteros-praga na agricultura brasileira. A multiplicação em massa do vírus para a produção comercial deve partir da seleção de isolados virais com alta virulência para resultar em um produto com alta efetividade contra a praga no campo. Dois isolados virais, obtidos de lagartas infectadas de Chrysodeixis includens em plantações de soja em Buritis-MG, foram purificados, identificados, analisados e avaliados quanto à atividade biológica por meio...

Autores: NOGUEIRA, S. R.; ANDRADE NETO, R. de C.; LUNZ, A. M. P.; COSTA, K. K. da.
A antracnose, causada por Colletotrichum gloesporioides, induz severos danos às folhas de açaizeiro (Euterpe precatoria), levando à morte de plantas, principalmente nas condições de viveiro. A doença é limitante para a produção de mudas de açaí-solteiro e consequentemente para expansão do seu cultivo. Os estudos com essa espécie ainda estão no início, sendo necessária a adoção de um conjunto de medidas para o controle eficiente da antracnose.

O objetivo do trabalho foi selecionar e analisar estirpes de bactérias e actinomicetos com potencial antagonista para o biocontrole do Fusarium verticillioides, causador de doenças na cultura do milho. O potencial antagonista de 80 isolados, de bactérias e actinomicetos, foi avaliado in vitro por meio do método de culturas pareadas. Dentre os isolados avaliados, foram selecionados Act.336, B.1433 e Act.9, devido aos maiores índices de inibição contra o fitopatógeno, com valores de 66,9%, 53,1% e 51,9%, respectivamente. A seguir, avaliou-se a influência de metabólitos produzidos por estes microrganismos para a inibição do crescimento micelial fúngico em meio líquido e germinação de conídios do patógeno em meio sólido. Estes isolados pré-selecionados...

Provedor de dados: 14
Autores: SAUERESSIG, T. M.; ALVES, R. M. R.
A mosca-dos-chifres, Haematobia irritans e considerada a maior praga dos bovinos nos Estado Unidos (Drummond et al., 1981) e uma das maiores pragas na Australia, sendo tambem muito importante na Europa. No Brasil, a mosca ocorre praticamente em todo o Pais, e os pecuaristas, especialmente da regiao do Cerrado, tem apontado o inseto como responsavel por grandes prejuizos. Sua introducao ocorreu por volta de 1976 na regiao norte, e a partir dai dispersou-se rapida e eficientemente. No Distrito Federal, a mosca foi observada pela primeira vez em 1990 (Saueressig, 1990). Por ser uma praga relativamente nova, existe pouca informacao sobre sua epidemiologia, controle e possiveis danos (nivel e grau de prejuizo) nessa regiao. A partir da sua dispersao no Brasil,...

Manguezais: potencial fonte de microrganismos para o uso como agentes de biocontrole da podridão radicular e promotores de crescimento de plantas em hidroponia.
Provedor de dados: 14
Autores: CORRÊA, E. B.; GALVAO, J. A. H.; BETTIOL, W.
Resumo: Microrganismos residentes de manguezais são adaptados aos baixos teores de oxigênio e flutuações de salinidade, condições encontradas em ambientes hidropônicos. Essa adaptação ecológica torna esses microrganismos em potenciais agentes de controle biológico de podridões radiculares, importantes doenças que incidem sobre cultivos hidropônicos e promotores de crescimento de plantas, pois um dos principais problemas encontrados no biocontrole e na promoção de crescimento em hidroponia é a baixa adaptação dos microrganismos introduzidos. O objetivo do trabalho foi avaliar a capacidade de 28 isolados de microrganismos residentes de manguezais no controle da podridão radicular causada por Pythium aphanidermatum e na promoção de crescimento em pepino...

Inseticidas piretróides no controle de pragas.
Provedor de dados: 14
Autores: ROMAN, E. S.; OLIVEIRA, M. A. S.
A piretrina, uma mistura crua de piretróides naturais é, talvez, o mais antigo dos inseticidas e, 135 anos após a sua introdução, tem ainda deslocado muitos de seus novos competidores, especialmente em uso doméstico devido a sua baixa toxidade para mamiferos. A forma mais comum nas quais os piretróides naturais são usados é como extrato de piretro, obtido por tração das flores por meio de solventes,como o metanol e a acetona, obtendo-se uma solução de piretróides,ceras e pigmentos, que serão separados.

ABSTRACT: Integrated weed management (IWM) is essential to sustainable agricultural production by reducing costs and nega tive environmental impact. Weeds are not necessarily undesirable and, in certain situations, they are more beneficial than harmful, contributing to integration of control methods. It has been demonstrated that crops coexist with weeds in certain growth phases of both without yield damage. This change of traditional approach, however, is not always easy to implement due to the concept that weeds need to be eliminated of the agricultural environment at any cost. A form to promote change in attitude is to deliver detailed, simple and objective information to farmers. Researchers have accumulated information be delivered by various means....

RESUMO: Atualmente existem ao redor de 60 mil hectares cultivados com seringais nas áreas de escape, onde o percevejo-de-renda Leptopharsa heveae é considerado como o principal inseto-praga. Este trabalho foi desenvolvido como o objetivo de avaliar a eficiência do fungo Sporothrix insectorum formulado em óleo emulsionável no controle do percevejo-de-renda da seringueira em seringais de cultivo, e compara-lo com o método químico. A multiplicação do fungo foi realizada em arroz autoclavado. No seringal utilizado, um hectare foi destinado à área testemunha, um segundo hectare para a aplicação do inseticida químico e um terceiro para a aplicação do bioinseticida. Na formulação à base de fungo foi utilizada uma concentração de 1x10(elevado a 12) esporos puros...

Controle de plantas invasoras em lavouras de café em formação no Estado do Acre.
Provedor de dados: 14
Autores: OLIVEIRA, V. H. de; ALVARENGA, M. I. N.; SALES, F. de.
A existência de áreas potenciais, ecologicamente favoráveis à cultura do café, levou o governo do estado do Acre a incluí-la, ao lado da seringueira e castanheira, como opção de cultivo nos projetos de colonização, em vários municípios acreanos. Além dos aspectos agronômicos favoráveis, confirmados pelas plantações existentes que, na grande maioria, são efetuados por pequenos produtores, a cultura do café é sócio-economicamente viável, com amplas possibilidades de êxito na região. O cafeeiro, como a maioria das culturas, é muito sensível a infestação e ocorrência natural de plantas daninhas que, devido às condições de umidade e temperatura da região, têm desenvolvimento exuberante, concorrendo com a cultura em nutrientes, água e luz. Não há dúvida de que o...

Autores: DIAS, N. da S.; OLIVEIRA, N. R. X de; CELIN, E. F.; COSTA-LIMA, T. C. da; PAIVA, L. G. G.
A mosca-minadora é a principal praga do meloeiro no Brasil e motivo para o uso abusivo de inseticidas. Considerando que a implantação de cultivares resistentes se apresenta como uma alternativa promissora, este trabalho avaliou o efeito de diferentes linhagens de meloeiro sobre a biologia (número de minas, sobrevivência larval e pupal) da mosca-minadora Liriomyza sativae, com o objetivo de encontrar, entre os materiais testados, linhagens que sejam menos danificadas por L. sativae . Avaliaram-se 17 linhagens de meloeiro, provenientes do Programa de Melhoramento de Melão da Embrapa, incluindo o híbrido comercial ?Goldex? como testemunha suscetível. No teste com chance de escolha, não foram constatadas diferenças significativas entre as linhagens em relação...

Desafios no controle de moscas-minadoras em tomateiro.
Provedor de dados: 14
Autores: COSTA-LIMA, T. C. da.
O crescente aumento da importância das moscas-minadoras tem trazido preocupação aos produtores de tomate em várias regiões do País. Dependendo dessa região, a praga é conhecida por diferentes nomes, como mosca-minadora, larva-minadora, minador ou riscador. Estes nomes comuns se referem a quatro espécies principais que são pragas no País, sendo estas Liriomyza sativae, L. trifolii, L. huidobrensis e L. brassicae. A espécie L. sativae é a que se encontra mais associada ao tomateiro e também em outras culturas, como o melão e o feijão.

Provedor de dados: 14
Autores: GASSEN, D. N.
Os pulgões, pragas do trigo no Brasil, são nativos da Ásia e da Europa de onde, provavelmente, foram introduzidos na América. Neste novo ambiente, livres de seus inimigos naturais, atingiram altas populações na década de 70. Em 1978, o Centro Nacional de Pesquisa de Trigo (CNPT) iniciou um programa de controle biológico de pulgões, introduzindo parasitos das regiões de origem da praga.

Autores: COSTA-LIMA, T. C. da.
Em junho de 2015, produtores de uva de mesa de Lagoa Grande, PE relataram danos em flores e bagas causados por uma pequena lagarta. Esta foi identificada como Lasiothyris luminosa (Razowski &amp; Becker) (Lepidoptera:Tortricidae), espécie até então não conhecida como um inseto-praga (CostaLima et al., 2016). O único registro existente da espécie, havia sido feito em 1969, no município de Brusque, SC (Razowski; Becker, 1983). Portanto, até o momento, trata-se de uma praga descrita apenas no Brasil. Considerando-se os danos causados por L. luminosa, em 2017, a espécie foi incluída na lista de alerta da Organização Europeia e Mediterrânea para Proteção de Plantas (EPPO, 2017). Em 2019, Argentina, Uruguai e Paraguai incluíram restrições fitossanitárias...

Bioecologia e controle da broca pequena do tomateiro neoleucinodes elegantalis.
Provedor de dados: 14
Autores: CARNEIRO, J. da S.; HAJI, F. N. P.; SANTOS, F. de A. M.
A cultura do tomate na Serra da Ibiapaba, no Estado do Ceará, é considerada uma das atividades agrícolas mais importantes e geradora de divisas para esta região. Entretanto, apresenta como uma das pragas chave a broca pequena, Neoleucinodes elegantalis (Guen.) (Lepidoptera: Pyralidae). Essa praga ocorre geralmente em elevadas infestações, ocasionando danos à produção em até 90%, pela destruição e apodrecimento dos frutos, levando os produtores a realizarem até duas pulverizações por semana. Sua ocorrência foi constatada no Brasil, em 1922, no Ceará, e em 1939, em São Paulo, encontrando-se atualmente disseminada em quase todas as regiões produtoras de tomate do Brasil. Na região Nordeste, a sua ocorrência é generalizada, exceto no Submédio do Vale do São...

Em todos os tipos de sistemas produtivos, quer sejam monocultivo ou policultivo, irrigado ou de sequeiro, agroecológico ou onvencional, grande parte das limitações da produção está vinculada a ocorrência de pragas. Os diferentes cultivos de importância econômica (commodities ou não), que visam a sustentabilidade da produção agrícola, têm por princípio direcionar suas ações para o manejo das pragas com base em princípios ecológicos. Os sistemas agroecológicos, por sua vez, têm por objetivo a otimização da produção de forma a garantir a sustentabilidade do agroecossistema, conferindo qualidade e segurança ambiental. As técnicas de produção não precisam necessariamente ser as mais sofisticadas, entretanto devem atender às necessidades das práticas de cultivo...

Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) é um inseto polífago, nativo da Ásia e de importância econômica para cultivos no Brasil, onde é conhecido por Drosófila-da-Asa-Manchada (DAM) ou ?Spotted Wing Drosophila? (SWD). DAM é uma importante praga de pequenas frutas em diferentes países, com sua principal estratégia de manejo baseada no controle químico. Entretanto, algumas características do controle biológico o tornam uma boa estratégia para o manejo desse inseto. Entre elas estão a capacidade de muitos parasitoides atacarem as larvas dentro das frutas, onde os agrotóxicos são geralmente menos eficazes, bem como pelo fato de que inimigos naturais são capazes de interferir na mortalidade natural de populações de pragas presentes em...

In Brazil as in the rest of the world, sectors of production and commercialization of animal originated foods, are changing to attend the two highst marcket demands: competitivity and quality. These exigencies are specially related to healthy foods. So the use of products that leave residues in meat and/or milk is going to be more restritive in an animal production system pointed to sustentability with lower environmental risks. Factors such as: pasture seasonal fluctuations, nutricional defficiencies, management conditions, high parasites incidence and general diseases contribuited to reduction of production and productivity of bovines. Verminosis is the name to the infections caused by endoparasites. In the tropics, these deseases usually show low...

Tropical House Gecko (Hemidactylus mabouia) predation on brown spiders (Loxosceles intermedia)
Provedor de dados: 80
Autores: Ramires,E.N.; Fraguas,G.M.
Brown spiders (Loxosceles spp.) are venomous arachnids, successfully adapted to urban habitats in Brazil. Loxoscelism became a serious public health problem in Paraná State, especially at the capital Curitiba, where the most abundant species is Loxosceles intermedia. Hemidactylus mabouia (Gekkonidae) lizards are synanthropic predators of arthropods. In this paper, we describe the predatory behavior of the Tropical House Gecko H. mabouia on L. intermedia under laboratory conditions. Twelve geckos were observed, and all of them fed on brown spiders (n=123 observations). The attack consisted of a fast run followed by one bite on the spider’s abdomen or legs. The geckos did not attack L. intermedia anterior body parts, probably due to the fangs present in this...

Insecticidal activity of venomous saliva from Rhynocoris fuscipes (Reduviidae) against Spodoptera litura and Helicoverpa armigera by microinjection and oral administration
Provedor de dados: 80
Autores: Sahayaraj,K; Vinothkanna,A.
Rhynocoris fuscipes is a potential predator of many economically important pests in India. In the present study, its venomous saliva (VS) was collected by milking and diluted with HPLC grade water to different concentrations (200, 400, 600, 800 and 1000 ppm). Microinjection of Rhynocoris fuscipes VS was more toxic than its oral administration in Helicoverpa armigera (cotton bollworm) and Spodoptera litura (tobacco cutworm). Thus, R. fuscipes VS was found to be toxic to third instar S. litura and H. armigera with respective LD50s of 846.35 and 861.60 ppm/larva at 96 hours after microinjection. The current results showed that VS of Rhynocoris fuscipes caused mortality of H. armigera and S. litura. Active peptides from VS may be isolated, identified and...

For the first time an ichneumonoid parasitoid is reported from the peach flatheaded rootborer Capnodis tenebrionis (Linnaeus, 1758) (Coleoptera: Buprestidae) in a heavily infested plum and apricot orchard in south-western Sicily. In 2005 and 2006 the ecology of the ectoparasitoid Spathius erythrocephalus Wesmael, 1838, (Hymenoptera: Braconidae) was studied. The larvae are ectophagous and gregarious; obviously the parasitoid search for the large buprestid larval (6.0 ± 0.4 cm). The adult parasitoid appeared in both cultivations in August and/or September and selected only the mature larvae for oviposition. In 2006 35% of the rootborer larvae on plum were parasitized. Significant diff erences were found between the mean depth in the soil in which parasitized...

The effects of stage structure and host density on baculovirus horizontal transmission were examined in the laboratory using larvae of the cabbage moth, Mamestra brassicae L. (Lepidoptera: Noctuidae). Insects were reared at three instar combinations and three host densities in closed containers with infected larvae. Insects were observed daily and the number of deaths and time to death were recorded. Levels of virus mortality were marginally higher in the containers where a higher density of hosts was introduced. Larvae appeared to have a greater risk of infection when late instar combinations were used. Final levels of mortality of older larvae were significantly higher than those of younger larvae. Mean times to death of larval populations were longer...

Natural enemies of the chinch bug, Blissus antillus Leonard (Hemiptera: Lygaeidae: Blissinae), pasture pest in Rio de Janeiro state, Brazil
Provedor de dados: 82
Autores: CORACINI,DÉBORAH L.A.; SAMUELS,RICHARD I.
This study aimed to identify natural enemies of the chinch bug, Blissus antillus Leonard, which attacks Tanner grass (Brachiaria arrecta) and Tangola (hybrid of B. arrecta and B. angola), in poorly drained pastureland in the northern region of Rio de Janeiro State. Immature stages of a parasitic mite, identified as Leptus sp. (Parasitengona: Erythraeidae), were commonly found attacking nymphs and adult chinch bugs in all sampled areas of Rio de Janeiro State. An egg parasitoid, Eumicrosoma sp. (Hymenoptera: Scelionidae), was observed on only two occasions attacking eggs which had been collected on plant stems in the field. These natural enemies are possible candidates for biological control programs. Despite extensive sampling, B. antillus was not observed...

Effect of neem seed oil aqueous solutions on survival and development of the predator Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae)
Provedor de dados: 82
Autores: Silva,Flávia A.C. da; Martinez,Sueli S.
The effects of the neem seed oil aqueous solutions on survival and performance of egg, larva and adult stage of the Coccinelid predator Cycloneda sanguinea (L.) were evaluated under laboratory conditions. In a first trial, eggs and 2nd-instar larvae were sprayed with the neem solutions at 0; 0.5 and 2.25 ml/l and kept at 25 ± 1ºC, 70% RH and 14h photoperiod. Egg viability and duration and larvae and pupae survival were evaluated as well as the predatory capacity of the larvae, adult longevity and reproduction. Egg spraying did not affect egg hatch or larvae survival and development. When the larvae were sprayed, significant mortality was observed only at the higher concentration (P &lt; 0.05) and larval development and predatory capacity were not affected....

Autores: Bellini,Marcos R; Araujo,Ralf V de; Silva,Edmilson S; Moraes,Gilberto J de; Berti Filho,Evoneo.
Several annual and perennial crops are severely attacked by mites from the family Eriophyidae, Tenuipalpidae and Tetranychidae. A suitable alternative commonly used in several countries for the control of these pest mites involve the use of predatory mites in the family Phytoseiidae. The phytoseiid fauna in the Brazilian natural vegetation is very rich, but nothing is known about the biology of most of these species, as it is the case with Proprioseiopsis cannaensis (Muma). The objective of this study was to determine biological parameters of P. cannaensis fed on pest mite species such as Phyllocoptruta oleivora (Ashmead) (Eriophyidae), Brevipalpus phoenicis (Geijskes) (Tenuipalpidae) and Tetranychus urticae Koch (Tetranychidae).

Screening of Beauveria bassiana (Deuteromycotina: Hyphomycetes) isolates against nymphs of Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae) with description of a new bioassay method
Provedor de dados: 82
Autores: Vicentini,Sérgio; Faria,Marcos; Oliveira,Maria R.V. de.
A bioassay method that uses melon leaves as substrate for eggs and nymphs of the biotype B of Bemisia tabaci (Genn.) was established. Root formation of petioles immersed in tap water guaranteed the turgidity and normal coloration of leaves for a period of 20 to 25 days, enabling the execution of tests with entomopathogenic fungi. The virulence of 50 isolates of Beauveria bassiana (Balsamo) Vuillemin was assessed, as an initial action of a research project that aims the development of a bioinsecticide for controlling Bemisia tabaci nymphs in melon crops. Melon leaves were infested with 18 couples of biotype B adults for 26 hours. First-instar nymphs were selected through microscopic observation approximately 4-5 days after adults removal.

Dark clouds and their silver linings: exotic generalist predators in augmentative biological control
Provedor de dados: 82
Autores: CLERCQ,PATRICK DE.
Several polyphagous arthropod predators are commercially available for augmentative biological control targeting mite and insect pests in a variety of cropping systems. A number of these predators are not native to the area of release. The current paper discusses benefits and risks of using exotic generalist predators as biocontrol agents. The fact that polyphagous predators are easily reared on unnatural foods and can be used against different pest species makes them attractive for commercialization. Polyphagous or facultatively phytophagous predators have less difficulty in maintaining their populations at low prey densities and can sometimes be introduced in the crop before the target pest is present, thus preventing the buildup of pest populations...

Invasions by Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) in the Western Hemisphere: implications for South America
Provedor de dados: 82
Autores: Koch,Robert L.; Venette,Robert C.; Hutchison,William D.
The multicolored Asian lady beetle, Harmonia axyridis (Pallas), native to Asia, has recently been detected in South America after successfully invading North America and Europe. This coccinellid is a voracious predator; therefore, it is popular and effective in biological control. Unfortunately, H. axyridis also has associated adverse impacts (i.e., as a household pest, pest of fruit production, and threat to non-target organisms). To predict the potential geographic extent of impacts of H. axyridis in South America we review the history of its invasion in the Western Hemisphere and address various factors critical to the future invasion (i.e., arrival, establishment, and spread) of new areas of South America. The likelihood of continued introductions...

Entomopathogenic nematodes: potential for exploration and use in South America
Provedor de dados: 82
Autores: GREWAL,PARWINDER S.; NARDO,ELIZABETH A. B. DE; AGUILLERA,MARINEIDE M.
Entomopathogenic nematodes have potential for biological control of insect pests. They are currently used for the control of soil and cryptic pests in North America, Europe, Asia and Australia. Entomopathogenic nematodes can be easily mass-produced and applied using conventional spray equipment. They have a broad host range and are safe to the environment. Due to the history of success with implementation of biological pest control programs, South American countries have a great opportunity to develop and implement the use of entomopathogenic nematodes. Recent emphasis on fruit and vegetable production in Brazil also stresses a need to implement safer and effective pest control methods. This paper provides an overview of recent developments in...

Biological, nutritional, and histochemical basis for improving an artificial diet for Bracon hebetor Say (Hymenoptera: Braconidae)
Provedor de dados: 82
Autores: Magro,Sandra R.; Dias,Alcides B.; Terra,Walter R.; Parra,José R.P.
The biology of Bracon hebetor Say (Hymenoptera: Braconidae) reared on fifth instars of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) (natural diet) and in vitro (artificial diet) was evaluated. Data on the number of instars, development time and food intake were collected, and histochemical tests were conducted to detect proteins and lipids in the parasitoid's digestive tract. The data disclosed differences that can help to improve artificial rearing of B. hebetor. B. hebetor had three instars in both diets, but the developmental time on the artificial diets was prolonged due to the increase in larval and pupal development times. Larvae grew faster on the natural host and required a lower food intake (2.7 µl) as compared to that required by the...

Interactions mediated by predators in arthropod food webs
Provedor de dados: 82
Autores: Venzon,Madelaine; Pallini,Angelo; Janssen,Arne.
Studies on interactions among plants, herbivores and natural enemies are important for understanding population dynamics of species in food webs, but they are also important for the practice of pest control with natural enemies. Biological control programs heavily rely on the occurrence of trophic cascades, where the addition of one natural enemy causes a decrease of pest densities and an increase of plant biomass. However, when more that one natural enemy is used to control various pests in the same system, artificial food webs are created and simple tritrophic interactions change to more complicated ones. The occurrence of complex interactions and omnivory in these food webs may modify the sign and the strength of direct effects of natural enemies on...

Eucalyptus are hosts of several psyllid species. Among them, Ctenarytaina eucalypti (Maskell) is considered the most harmful to Eucalyptus globulus plantations. In Brazil, this pest has been observed in the state of Parana, and in 2005, it was found causing damage to plantations of E. globulus in Arroio Grande and Piratini cities, RS. The monophagous endoparasitoid Psyllaephagus pilosus Noyes was also observed parasitizing nymphs of C. eucalypti. This parasitoid has been shown to be highly efficient in controlling this psyllid species, making unnecessary the use of any other control method.

This research intended to investigate if the presence of pesticides in the soil could affect the pathogenicity of Metarhizium anisopliae Metsch. (Sorokin) for Ceratitis capitata (Wied.) and assess the effect of conidia application as suspension or dry conidia. The fungicides chlorothalonyl and tebuconazol, the acaricide abamectin, the insecticide trichlorfon, and the herbicide ametrin were applied at the manufacturer-recommended doses. Soil samples were placed in glass flasks and were given the fungus as conidial suspension or dry. After pesticide application, 20 3rd-instar larvae were placed in the soil.

Autores: Gonçalves,José R.; Faroni,Lêda R.D'A.; Guedes,Raul N.C.; Oliveira,Carlos R.F. de.
The presence of natural enemies in stored grains and the need of pest control alternatives led to the assessment of the effect of insecticides on the mite species Acarophenax lacunatus (Cross &amp;amp; Krantz), an egg parasite of the stored grain pest Rhyzopertha dominica (Fabr.). The insecticides bifenthrin, deltamethrin, pirimiphos-methyl and fenitrothion were tested at 0.4, 0.5, 0.8 and 10 ppm, respectively. Insecticide treated wheat grains were spread in petri dishes and infested with 25 adults of R. dominica. Seven days later, three mites were added to each dish, in four replicates. The number of adults of R. dominica, grain weight loss and instantaneous rate of increase (r i) of A. lacunatus were lower when the grain was treated with deltamethrin....

Diapause in fruit fly parasitoids in the Recôncavo Baiano, Brazil
Provedor de dados: 82
Autores: Carvalho,Romulo da S.
Diapause has been poorly investigated in tephritid fruit flies and in associated parasitoids in tropical regions. In this work, diapause in larval-pupal parasitoids of fruit flies is reported for the region of the Reconcavo Baiano, Brazil. Diapause was recorded for individuals of four native species [Doryctobracon areolatus (Szépligeti), Utetes anastrephae (Viereck), Opius sp. (Hymenoptera: Braconidae), Aganaspis pelleranoi (Brethes) (Hymenoptera: Figitidae)] and of one exotic braconid [Diachasmimorpha longicaudata Ashmead]. Diapausing parasitoids were obtained from fruit fly puparia in fruits collected between November 1998 and April 2000. In all, 1.4% of individuals underwent diapause, being D. areolatus the most frequent. The development time for this...

Discovery and development of biological agents to control crop pests
Provedor de dados: 82
Autores: Slininger,Patricia J.; Behle,Robert W.; Jackson,Mark A.; Schisler,David A.
Thousands of potential microbial biocontrol agents have been isolated from agricultural fields and crops during research over the last 80 years, yet only a few are in commercial use. Recently, public health and safety concerns about the environmental impact of chemical pesticides have led to consideration of biological control as a natural approach to maintaining crop health. Despite environmental incentives and strong research efforts, commercialization of biocontrol agents has been slow to evolve. The momentum of the chemical industry is difficult to shift, and fermentation processes tend to be more expensive to operate than synthetic chemical processes.Yet there is a demand for biological control products, especially in agricultural niche markets, where...

Aedes aegypti (L.), the main vector of dengue fever in Brazil, has been controlled with the use of massive chemical products, contributing to the development of resistance and decreasing the insect control efficiency. The control of dipterans with bioinsecticides based on Bacillus thuringiensis has been satisfactory, due to the production of insecticidal proteins denominated Cry (crystal), Cyt (cytolytic) toxins and Chi (chitinase), and to the synergistic effects among them. The present work aimed to select B. thuringiensis isolates efficient against A. aegypti larvae. A bacterial collection containing 1,073 isolates of B. thuringiensis, obtained from different locations of Brazilian territory, had the DNA isolated and submitted to PCR amplifications using...

Provedor de dados: 82
Autores: Collier,Karin F.S.; Lima,Jose O.G. de; Albuquerque,Gilberto S.
This study was conducted to search for potential mite predators to control phytophagous mites in papaya orchards. Bimonthly surveys, from January 1999 to February 2000, were carried out in two orchards, one in Silva Jardim (RJ), where pests are naturally controlled, and one at Linhares (ES), where pests are chemically controlled. All mite species collected from buds, new leaves, old leaves, and floral buttons of papaya trees and from weed leaves were quantified and identified to at least family level. Despite the relatively diverse mite fauna, we found representatives of only one family of predacious mites, i.e. Phytoseiidae. Among these, Neoseiulus idaeus Denmark &amp;amp; Muma was the most abundant and frequent during all seasons in the Linhares orchard,...

Autores: FOERSTER,LUÍS A.; DOETZER,AUGUSTA K.
The effect of four temperatures on the development of the larval endoparasitoid Peleteria robusta (Wiedman) as well as its preference for different instars of the host, the armyworm Mythmina(Pseudaletia) sequax Franclemont were evaluated. Females of P. robusta laid more than one egg outside the cuticle of the caterpillars, however only one parasitoid developed and pupated within the host. Females of P. robusta successfully parasitized the fourth- to sixth-instars of M. sequax, with preference for the fourth and fifth instars of the host. No parasitoids emerged from caterpillars exposed to P. robusta females between the first and third instars. The development of P. robusta to the adult stage was completed in the range between 15ºC and 30ºC, and the...

Autores: Silva,Roberta Z. da; Neves,Pedro M.J.O.; Yamashita,Fábio; Santoro,Patrícia H.
One of the requirements for successful commercial production of biological control agent is the maintenance of viability for long periods at room temperature, increasing shelf life. The water activity (Aw) is an important parameter to study the stability in the storage of dehydrated products but its determination demands equipments not always available. The water sorption isotherms correlate the Aw with the moisture of a product; adsorption isotherm is important to define the packaging system, and desorption isotherm the drying process. The objective of this study was to determine the sorption isotherms of Beauveria bassiana conidia and adjust them using a mathematical model. The adsorption and desorption were determined by gravimetric technique at 25°C...

Provedor de dados: 82
Autores: DIEHL,ELENA; JUNQUEIRA,LUCIANE K.
Mechanisms involved in maintaining colonies of social insects free of pathogens are among the main aspects of interest in the evolutionary biology of this group. For ants, it has been suggested that secretion from the metapleural glands play an important role in colony asepsis. In this study, different worker subcastes of the fungus-growing ant Atta sexdens piriventris Santschi were compared in relation to presence of metapleural secretion during a year. At the same time, the topical activity of the secretion was tested on workers treated with the entomopathogenic fungus Beauveria bassiana (Bals.) Vuillemin. Based on the mean width of the cephalic capsule, six worker subcastes were defined: gardener, minor, media, large, major and soldier. A positive...

Autores: Santos-Cividanes,TM; Anjos,ACR dos; Cividanes,FJ; Dias,PC.
The lady beetle Coleomegilla maculata (De Geer) is a natural enemy of several insect pests and feeds on pollen and nectar to survive periods when prey is scarce. The effect of the feeding interval on the development, survival, fecundity, and longevity of C. maculata was determined. Newly hatched larvae of C. maculata were reared individually and fed with eggs of the Mediterranean flour moth Anagasta kuehniella (Zeller) at intervals of one, two, and three days under controlled conditions (23 ± 1ºC; 60 ± 10% RH; 12 h phtophase). The duration of larval instars and the total larval stage was prolonged as the feeding interval increased. The larval period lasted on average 9.2 ± 0.19 days when the larvae were fed daily with prey, and 14.6 ± 0.48 days when food...

Occurrence of apocrine secretion in the larval gut epithelial cells of Aedes aegypti L., Anopheles albitarsis Lynch-Arribálzaga and Culex quinquefasciatus say (Diptera: Culicidae): a defense strategy against infection by Bacillus sphaericus Neide?
Provedor de dados: 82
Autores: Oliveira,Caroline D; Tadei,Wanderli P; Abdalla,Fábio C.
Cell hypertrophy was the first reaction of the gut epithelial cells of Aedes aegypti (L.), Anopheles albitarsis (Lynch-Arribálzaga) and Culex quinquefasciatus (Say) to the toxins of strains 2362 and S1116 of Bacillus sphaericus, as cells had an increase of intracellular secretory activity. Soon after the cell hypertrophy developed, vesicles were formed at the cell apical portion, which detached with the plasma membrane, characterizing a type of apocrine secretion like. The first pathway of contamination of the mosquito larvae by these bacteria is through the gut, by feeding. Depending on the species of Culicidae and on the bacterial strain used, the hypertrophy of the gut epithelium occurred between 5 and 15 min after exposure to the contaminated...

Provedor de dados: 82
Autores: Carvalho,Alessandra R.; Bueno,Vanda H.P.; Pedroso,Elizabeth C.; Kon,Leonardo I.; Diniz,Alexandre J.F.; Silva,Robson J.
Several species of Orius Wolff are used in biological control of thrips in protected cultivations in temperate regions, but some of them show reproductive diapause, compromising the efficiency of these agents of biological control. There are no reports on the biology of the neotropical species Orius thyestes Herring under different environmental conditions. The purpose of this work was to investigate the influence of photoperiod on reproduction and longevity of this predator. Nymphs were kept in petri dishes in climatic chambers at 28 ± 1°C, 70 ± 10% RH and under the photoperiods of 12L:12D, 11L:13D, 10L:14D e 09L:15D. The mating adults were kept in petri dishes with Bidens pilosa L. Asteraceae inflorescences as oviposition substracts and eggs of Anagasta...

Autores: Pesquero,MA; Dias,AMPM.
Solenopsis saevissima (Smith) and Solenopsis invicta Buren are the most abundant and widely distributed fire ants in Brazil. The occurrence of the two fire ant species and of their parasitoids Pseudacteon spp. is described for a climatic and phytophysiognomic transition area in the state of São Paulo. Both fire ant species have a parapatric distribution, apparently determined by the climate: S. saevissima predominates in the north part of São Paulo (Aw climate), while S. invicta in the south (Cfa climate). A sympatric area is observed between the latitudes 21ºS and 23ºS. Two different communities of parasitic decapitating flies were associated with S. saevissima in the north and with S. invicta in the south, with a sympatric area in the municipality of São...

Autores: Luna,MG; Wada,VI; La Salle,J; Sánchez,NE.
We report the first record of Neochrysocharis formosa (Westwood) parasitizing larvae of the tomato moth, Tuta absoluta (Meyrick), in tomato crops in Northern Buenos Aires Province, Argentina. Tomato moth larvae were sampled during four consecutive growing cycles, between 2003 and 2005, in 10 sites. Neochrysocharis formosa was present only in organic outdoor and protected crops, and predominantly during the late season. Parasitism rates varied from 1.5% to 5%. The finding of this species is a new record for Argentina and South America, and T. absoluta is a new host record.

Autores: Yamamoto,Ana C.; Foerster,Luís A.
The larval ectoparasitoid Euplectrus ronnai (Brèthes) is one of the components of a species complex that attacks the armyworm Mythimna (Pseudaletia) sequax Franclemont (Lepidoptera: Noctuidae). No data are available on the fecundity, longevity and host instar preference of E. ronnai, what prompted the conduction of this research. No parasitism occurred on the first and sixth instars of the host, and a positive relationship was found between host instar and the number of parasitoid eggs/host, which ranged from 1.5 on third- instar hosts to 3.6 on fifth instars. Females of E. ronnai showed a preference for either the fourth or fifth instar of M. sequax. There were no significant differences in the developmental time of the parasitoid, sex ratio, mean number...

Autores: CIOCIOLA JR.,AMÉRICO I.; QUERINO,RANYSE B.; ZUCCHI,ROBERTO A.; STOUTHAMER,RICHARD.
The sequence of the ITS2 (internally transcribed spacer 2) region of the rDNA was used to identify two closely related Trichogramma species: T. rojasi and T. lasallei, the second species recently reported in Brazil. The DNA of the samples was extracted using Chelex 100. The PCR product was linked to a pGEM-T® vector and both were then placed into Petri dishes to grow white colonies, which demonstrate the correct ligation between the vector and the DNA. From these colonies, 10µl were purified and sequenced using a special kit, and the sequences aligned using the ESEE 3.0 software. Specific primers were efficient to amplify the ITS2 rDNA region of the Brazilian Trichogramma. The sequence of each species differed in length and in nucleotide position, showing...

ヒメジンガサハナカメムシの発育と繁殖に対するミナミキイロアザミウマとカンザワハダニの餌の適合性を明らかにするため,それぞれの餌種を与えた場合の本種幼虫の生存率と発育期間,雌成虫の寿命と産卵数を比較した.ミナミキイロ1齢幼虫や2齢幼虫を与えた場合,本種1齢幼虫は発育できたが,ミナミキイロ雌成虫を与えた場合,ほとんど発育できなかった.一方,カンザワハダニは苦虫だけでなく雌成虫を餌として発育可能で,本種1齢幼虫の好適な餌であった.加齢にともない餌の違いが及ぼす影響は小さくなり,ヒメジンガサハナカメムシ5齢幼虫の生存率と発育期間,雌成虫の寿命と産卵数は,餌の種類の違いによる影響は受けなかった.従って,カンザワハダニもミナミキイロと同様にヒメジンガサの発育や繁殖に対して餌適合性が高いと考えられ,ヒメジンガサはこれら2種の害虫に対する天敵資材としての利用可能性があることが示唆された.  Effects of the prey species Thrips palmi and Tetranychus kanzawai and their stages on the development and reproduction of the anthocorid predator, Wollastoniella rotunda, were investigated under laboratory conditions.

Autores: 林, 佐季; 仲島, 義貴.
We investigated effects of sugar solution on adult longevity, progeny production and progeny sex ratio of Aphidius ervi in the presence and absence of host aphids. When female parasitoids were provided with 50% glucose–fructose solution in 1 : 1 ratio, they lived approximately twice longer than those provided with distilled water, irrespective of host aphid provision. The same effect of sugar solution was also observed on progeny production. When the parasitoid was fed sugar solution, its lifetime progeny production approximately doubled in comparison to that provided with water, whereas daily progeny production did not differ. Total number of female progeny did not differ between adult female provided with water and sugar solution, but significantly...

We studied the effects of plant species on the development of Wollastoniella rotunda under laboratory conditions. We reared newly emerged first instars of W. rotunda on eggs of Ephestia kuehniella together with one of four different plant leaves, eggplant, cucumber, kidney bean and tomato. As a control, we used either moist cotton wool or nothing instead of the plant leaves. In the absence of water, first instars died within a day, suggesting that the predator needs to acquire water from plants in order to survive. Survival rates of W. rotunda differed among plant species, being lowest on cucumber leaves when compared to eggplant or tomato leaves. The duration of instar development was not affected by plant species. When offered moist cotton wool, bugs...

The current study was conducted to investigate the pathogenicity and its mode of action by Verticillium lecanii hybrid strains in different sedentary stages of Heterodera glycines. Three different sedentary stages (pale yellow female, yellow brown cyst, and dark brown cyst) of H. glycines were treated with V. lecanii and incubated for 3 weeks on water agar. After 3 weeks of incubation, eggs were investigated for the following parameters: (i) the infection frequencies of eggs, (ii) the number of eggs laid, and (iii) the number of mature and healthy eggs. Subsequently, the fecundity of H. glycines treated with V. lecanii was investigated in greater detail. Consequently, some strains had a greater ability to infect eggs and this significantly reduced the...

Bacillus species can form endospores and have broad-spectrum activity of their antibiotics. For that reason, they offer several advantages over other bacteria for protection against root pathogens. This work was intended to determine the ability of Bacillus spp. to inhibit Verticillium dahliae. First, antagonistic activities of Bacillus spp. were studied in greenhouse trials. These results suggest that the bacterium can control soil-borne diseases. Secondly, to investigate the situation in a culture environment, Bacillus spp. were examined for their activity to control Verticillium black spot of Japanese radish and plant-growth promotion rhizobacteria (PGPR) effects in a field. After 2 months, these bacteria reduced Verticillium black spot of Japanese...

The role of semiochemicals in mediating intraguild interactions between the seven-spot ladybird, Coccinella septempunctata, and the aphid parasitoid, Aphidius ervi, was investigated. Female parasitoids avoided leaves visited by C. septempunctata adults and larvae during the previous 24 hr. Ethanol extracts of C. septempunctata adults and larvae also induced avoidance responses by A. ervi. Two of the hydrocarbons identified by gas chromatography ( GC) and coupled GC-mass spectrometry (GC-MS), n-tricosane (C23H48), and n-pentacosane (C25H52), when tested individually at levels found in the adult extract, induced avoidance by A. ervi. Further investigation of the larvae extract, and footprint chemicals deposited by adults in glass Petri dishes, confirmed the...

Autores: Verschuere, L.; Rombaut, G.; Huys, G.; Dhont, J.; Sorgeloos, P.; Verstraete, W.
The use of juvenile &lt;i&gt;Artemia&lt;/i&gt; as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for &lt;i&gt;Artemia&lt;/i&gt; juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effects on survival and/or growth of &lt;i&gt;Artemia&lt;/i&gt; juveniles under monoxenic culture conditions, while other strains caused no significant effect, significantly lower rates of survival and/or growth, or even total mortality of the &lt;i&gt;Artemia&lt;/i&gt; . The nine selected strains were used to preemptively colonize the...

Autores: Verschuere, L.; Heang, H.; Criel, G.R.J.; Sorgeloos, P.; Verstraete, W.
In this study &lt;i&gt;Vibrio proteolyticus&lt;/i&gt; CW8T2 has been identified as a virulent pathogen for &lt;i&gt;Artemia&lt;/i&gt; spp. Its infection route has been visualized with transmission electron microscopy. The pathogen affected microvilli and gut epithelial cells, disrupted epithelial cell junctions, and reached the body cavity, where it devastated cells and tissues. In vivo antagonism tests showed that pre-emptive colonization of the culture water with nine selected bacterial strains protected &lt;i&gt;Artemia&lt;/i&gt; juveniles against the pathogenic effects. Two categories of the selected strains could be distinguished: (i) strains providing total protection, as no mortality occurred 2 days after the experimental infection with &lt;i&gt;V....

Scanning electron microscopy of the interaction between Cryptococcus magnus and Colletotrichum gloeosporioides on papaya fruit
Provedor de dados: 86
Autores: Capdeville,Guy de; Souza Júnior,Manoel Teixeira; Santos,Jansen Rodrigo Pereira; Miranda,Simoni Paula; Caetano,Alexandre Rodrigues; Falcão,Rosana; Gomes,Ana Cristina Menezes Mendes.
The objective of this work was to investigate possible modes of action of the yeast Cryptococcus magnus in controlling anthracnose (Colletotrichum gloeosporioides) on post harvested papaya fruits. Scanning electron microscopy was used to analyze the effect of the yeast on inoculations done after harvest. Results showed that C. magnus is able to colonize wound surfaces much faster than the pathogen, outcompeting the later for space and probably for nutrients. In addition, C. magnus produces a flocculent matrix, which affects hyphae integrity. The competition for space and the production of substances that affect hyphae integrity are among the most important modes of action of this yeast.

Autores: Morais,Elisangela Gomes Fidelis; Oliveira,Jéssica Silva; Gondim Jr.,Manoel Guedes Corrêa; Moraes,Gilberto José.
Abstract: The objective of this work was to evaluate the efficiency of two Amblyseius largoensis (Acari: Phytoseiidae) populations in controlling Raoiella indica (Acari: Tenuipalpidae). The treatments were: release of A. largoensis from the island of La Réunion; release of A. largoensis from the state of Roraima, Brazil; and a control, without predator release. Initially, 20 predators were released per plant; three other releases were done at a rate of ten adults per plant, at 46, 135, and 156 days after the first release. The population densities were estimated every 20 days, during six months. Both A. largoensis populations evaluated are not sufficiently efficient to control the R. indica population.

Autores: Sauka,Diego Herman; Monella,Rodrigo Horacio; Benintende,Graciela Beatriz.
The objective of this work was to establish and test the induced-feeding bioassay in order to detect Bacillus thuringiensis insecticidal activity against Epilachna paenulata (Coleoptera: Coccinellidae). Larvae were induced to swallow high concentrations of spore-crystal suspensions of seven exotic and 30 Argentine B. thuringiensis strains. The great majority of strains showed no toxicity to E. paenulata larvae, and observed mortality was lower than 30%. Induced-feeding bioassay is feasible, and should be used for prospecting strains that produce right combinations of Cry proteins needed to an efficient pest control.

Autores: Silva,Cleonor Cavalcante; Laumann,Raul Alberto; Blassioli,Maria Carolina; Pareja,Martin; Borges,Miguel.
The objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively. Survival rate of immature stages and survivorship and reproduction of adults were determinated. Survivorship of nymph to adult was the highest (89%) at density 100 eggs per dish. Adult survivorship was independent of density, and 100 couples per cage were the best to improve quality of the produced progeny. In these conditions, fecundity was 160.8±9.28 eggs per female, and a total of 8,950±456 eggs per cage per month was produced. Two hundred couples per cage showed a negative...

Autores: Halfeld-Vieira,Bernardo de Almeida; Vieira Júnior,José Roberto; Romeiro,Reginaldo da Silva; Silva,Harllen Sandro Alves; Baracat-Pereira,Maria Cristina.
The objective of this work was to verify if the induced resistance mechanism is responsible for the capacity of a phylloplane resident bacteria (Bacillus cereus), isolated from healthy tomato plants, to control several diseases of this crop. A strain of Pseudomonas syringae pv. tomato was used as the challenging pathogen. The absence of direct antibiosis of the antagonist against the pathogen, the significant increase in peroxidases activity in tomato plants exposed to the antagonist and then inoculated with the challenging pathogen, as well as the character of the protection, are evidences wich suggest that biocontrol efficiency presented by the antagonist in previous works might be due to induced systemic resistance (ISR).

Autores: Oliveira,Carlos Romero Ferreira de; Faroni,Lêda Rita D'Antonino; Guedes,Raul Narciso Carvalho; Pallini,Angelo; Gonçalves,José Roberto.
The objective of this work was to assess the parasitism potential of Acarophenax lacunatus (Cross &amp;amp; Krantz) on Tribolium castaneum (Herbst). The experimental units encompassed Petri dishes containing 25 g of wheat infested with 20 adults of this beetle species. After seven days of infestation, different mite densities (0, 2, 4, 6, 8 and 10 females) were inoculated into the Petri dishes. The increase in mite density led to a linear increase in parasitism, and a consequent reduction in populations of this insect. It is possible to use this mite species in the biological control of T. castaneum.

Promotion of growth and control of damping-off (Rhizoctonia solani) of greenhouse tomatoes amended with vermicompost
Provedor de dados: 85
Autores: Rivera,MC; Wright,ER; López,MV; Garda,D; Barragué,MY.
The pathogen Rhizoctonia solani (teleomorph Tanatephorus cucumeris) can affect tomatoes germination and emergence and cause basal rot of seedlings. It is generally accepted that composts suppress plant diseases, improve soil nutrient availability and stimulate plant growth. However, no reports have been found on the simultaneous evaluation of vermicompost as plant growth promoter and suppressive to damping-off caused by R. solani on tomatoes. This research evaluated the suppressive effects of different concentrations of vermicompost against R. solani and the ability of vermicompost to promote tomato seedlings growth. The microbial composition of the substratum was explored. Thirty six microorganisms were isolated, 13 of which were antagonic to R.solani in...

Autores: ALI,A.; JAVAID,A.; SHOAIB,A.
ABSTRACT Sclerotium rolfsii is a soil-borne fungal plant pathogen that causes diseases in more than 500 plant species. Chemical fungicides used to control this disease cause environmental pollution, therefore, plant derived compounds can be used as alternative to synthetic fungicides to reduce environmental pollution. Chenopodium album is a weed of family Chenopodiaceae that is used as food and also has medicinal importance. In the present study, antifungal activity of methanolic root extract of C. album was evaluated against S. rolfsii using six concentrations viz. 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 g 100 mL-1 amended in malt extract as growth medium. All the root extract concentrations significantly reduced fungal biomass by 15-58% over control. Gas...

Sm. dry biomass application (1%, 2% and 3% w/w) and two species of Trichoderma (T. viride and T. aureoviride) on growth and physiology of mungbean [Vigna radiata (L.) WIlczek] under biotic stress of Macrophomina phaseolina (Tassi) Goid. Inoculation of M. phaseolina (positive control) reduced plant survival, shoot and root length as well as plant dry biomass by 22%, 52%, 61% and 64%, respectively, over the negative control (without any amendment). There was 100% plant survival in treatments with T. aureoviride alone or in combination with 1% and 2% C. didymus biomass. Likewise, T. viride in combination with 2% biomass also showed 100% plant survival. Application of 3%...

Biological Management of Basal Rot of Onion by Trichoderma harzianum and Withania somnifera
Provedor de dados: 87
Autores: AKHTAR,R.; JAVAID,A.
ABSTRACT: Onion is attacked by destructive soil-borne fungal plant pathogen Fusarium oxysporum f. sp. cepae, resulting in basal rot disease. In the present study, three Trichoderma species (T. pseudokoningii, T. harzianum and T. reesei) and leaves of solanaceous weed Withania somnifera were used for management of this disease. The in vitro interaction study revealed T. harzianum as the most effective biocontrol agent against the pathogen. In a pot trial, dried leaf material of W. somnifera (1%, 2% and 3% w/w) and inoculum of T. harzianum were mixed in the pot soil previously inoculated with the pathogen. The highest incidence of the disease (87%) was found in positive control (pathogen inoculation without any amendment). Different rates of dry leaf...

The braconid larval parasitoid Cotesia flavipes Cameron was introduced from Asia into East and Southern African region starting in 1993 to control the invasive exotic maize stemborer Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). A quasi-experiment was constructed using farmers that applied sublethal dosages of pesticide in assessing the counterfactual for the impact of the establishment of the introduced parasitoid in five countries in the region. Logistic regression method was used to estimate the probability that farmers’ would inadvertently exclude parasitoids in their maize field. Thereafter the propensity score matching method was used to find corresponding farmers excluding parasitoids among those who did not for yield comparison. The...

PREDICTED FUTURE ECONOMIC IMPACTS OF BIOLOGICAL CONTROL OF LEAFY SPURGE IN THE UPPER MIDWEST
Provedor de dados: 31
Autores: Bangsund,   Dean A.; Leistritz,   F. Larry; Leitch,   Jay A.
The Leafy Spurge Biological Control program was designed to use insects and plant diseases from the plant's original European habitat to control infestations in the United States.  The widespread adoption of biological agents to combat leafy spurge and the initial success in reclaiming previously infested land has prompted an evaluation of the potential future economic benefits of the biological control of leafy spurge in the Upper Midwest.  Based on expert opinion and historical data, leafy spurge in Montana, North Dakota, South Dakota, and Wyoming was projected to infest 1.85 million acres, of which, 65 percent was estimated to controlled with biological agents by 2025.  Based on a survey of county weed board personnel, North Dakota and Wyoming are...

Selective vs. Broad-Spectrum Pesticides: When Do Private Decisions Differ from Socially Optimal Decisions?
Provedor de dados: 31
Autores: Grogan,   Kelly A.; Goodhue,   Rachael E.
This paper examines the spatial externalities of conventional and organic pest control methods to determine if, and how, the two types affect each other. These interactions make the problem more complicated than the usual analysis of a single externality. The numerical simulation model includes one organically managed and one conventionally managed field. One pest and one predator of the pest move between the two fields over five seasons. In each season, the conventional grower has the option of applying a broad-spectrum pesticide that kills the predator a selective pesticide that has no adverse effects on the predator but is either more expensive or less effective than the broad-spectrum pesticide. The organic grower can apply an organic pesticide,...

Ecological engineering: a new direction for agricultural pest management
Provedor de dados: 31
Autores: Gurr,   Geoff M.; Wratten,   Steve D.; Altieri,   Miguel A.
Ecological engineering has recently emerged as a paradigm for considering pest management approaches that are based on cultural practices and informed by ecological knowledge rather than on high technology approaches such as synthetic pesticides and genetically engineered crops (Gurr et al. 2004a). This article provides a brief summary of ecological engineering for arthropod pest management and contrasts it with its controversial cousin, genetic engineering. The development of ecological engineering is explored, ranging from a simple first approximation that diversity is beneficial, to contemporary understanding that diversity can have adverse effects on pest management. This requires that the functional mechanisms that lead components of biodiversity to...

Autores: Hodur,   Nancy M.; Leistritz,   F. Larry; Bangsund,   Dean A.
Leafy spurge is an exotic, noxious, perennial weed which is widely established in the north central United States and is an especially serious problem in the northern Great Plains.  In 1997, the Agricultural Research Service and the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture (USDA), initiated a major Integrated Pest Management (IPM) research and demonstration project, TEAM Leafy Spurge (TLS), to develop and demonstrate ecologically based IPM strategies that can produce effective, affordable leafy spurge control.  A key component of the project was to expand the use of biological control (biocontrol) agents, specifically flea beetles.  To assess the level of insect establishment and the level of current and perceived...

Biological control of invasive plant species: stochastic economic analysis
Provedor de dados: 31
Autores: Chalak-Haghighi,   Morteza; Ruijs,   Arjan; van Ierland,   Ekko C.
We analysed to what extent the stochastic effects of two biological control agents (i.e. weevils and mycoherbicides) affect the optimal choice of Californian thistle control. A stochastic, dynamic optimisation model was set up to analyse strategies that maximise the expected net present values. We analysed the cost-effective strategies to control the thistle for deterministic and stochastic cases. Results show that the stochasticity of the efficacy of weevils does not affect the optimal strategy. Compared to the deterministic case, however, mycoherbicides will be introduced at a higher level of weed density if we take the stochastic effect of mycoherbicides into account.

Measuring the economic value of redistributing parasitoids for the control of the maize stemborer Busseola fusca Fuller (Lepidoptera: Noctuidae) in Kenya
Provedor de dados: 31
Autores: Kipkoech,   Anderson Kipruto; Schulthess,   Fritz; Yabann,   Wilson K.; Kipsat,   Mary J.; Mithofer,   Dagmar.
This study assesses the ex ante economic impact of the establishment of two parasitoids, the scelionid egg parasitoid Telenomus isis Polaszek from West Africa and a virulent strain of the braconid larval parasitoid Cotesia sesamiae Cameron from western Kenya, to control stemborer. Using a Cobb-Douglas production function, it was estimated that yields increased by 28.5% when pesticides were used to control stemborers. The benefit-cost ratio after the establishment of the parasitoids ranged from 1:1 to 777:1, with a net present value of up to US$192 million. The study demonstrates the potential of redistributing parasitoids indigenous to Africa for the control of African stemborers. Because the benefits of biological control are positively scale dependent,...

Spatially Optimal Habitat Management For Natural Pest Control Services
Provedor de dados: 31
Autores: Zhang,   Wei; van derr Werf,   Wopke; Swinton,   Scott M.
The control of crop pests by their natural enemies represents an important ecosystem service that maintains the stability of agricultural systems and has the potential to mitigate pest control costs. Recently, there has been growing interest in enhancing natural control services via habitat management that provides resources for adult natural enemies, such as food and shelter. Management of natural enemy populations has received little attention in the economic literature on pest control. Most such prior studies have explored optimal chemical-based pest management. One recent paper developed a threshold-based pesticide decision rule to account for the presence of natural enemies. However, no prior studies have investigated economically optimal spatial...

ABSTRACT Beauveria bassiana is naturally found in broiler chicken houses, and has been shown to be active against the lesser mealworm, Alphitobius diaperinus. The effectiveness of soil application of B. bassiana in emulsifiable oil-type formulation (Unioeste 4 isolate) to control the lesser mealworm in commercial poultry house was evaluated. The fungus was applied to the dirt floor of poultry house at 4.2 × 109 conidia/m2 (treated aviary) and the insect population was assessed before and 96, 146 and 216 days after application (DAA). In the control aviary, no treatment was performed to control those insects. Molecular techniques were used to confirm the presence of the fungus in dead A. diaperinus. Significant treatment effects were observed, with 56% and...

ABSTRACT This is the first report of Cotesia scotti (Valerio and Whitfield) comb. nov. in Brazil, attacking larvae of the black armyworm, Spodoptera cosmioides, and the southern armyworm, S. eridania. The moth larvae were found respectively, infesting a protected cropping of organic tomato in Hidrolândia, Goiás, Brazil, and a transgenic soybean crop in São José dos Pinhais, Paraná, Brazil. Biological, molecular and morphological characters were used to confirm the identity of the specimens. Parasitoid identification presented a challenge since the species has most diagnostic characters of the genus Cotesia Cameron, but few in the poorly defined genus Parapanteles Ashmead. Based on morphological and molecular evidence, we transfer Parapanteles scotti to the...

Interaction betweeen Telenomus remus and Trichogramma pretiosum in the management of Spodoptera spp. The use of egg parasitoids is a promising strategy for Integrated Pest Management (IPM), but different species of parasitoids have greater or lesser control efficiency, depending on the pest species. Recently, not only Anticarsia gemmatalis and Pseudoplusia includens but also Spodoptera cosmioides and S. eridania have been among the key Lepidoptera larvae attacking soybeans. This study evaluated the combination of Telenomus remus and Trichogramma pretiosum for parasitism of eggs of the Spodoptera complex, for better control efficiency and broader spectrum of action among the key pests of soybeans. The experiment was carried out under controlled...

Abstract Harmonia axyridis is an exotic species that can cause serious impacts on native biodiversity in areas where it is introduced to act as a biological control agent. This predator is often involved with intraguild predation, in most cases with aphids predators. Here, we report the results of experiments designed to understand the outcome of the invasion of H. axyridis on native coccinellid aphidophagous guilds using intraguild predation as a theoretical framework. Tests were conducted to determine the interactions between 1st and 4th instars larvae and H. axyridis adults, with Cycloneda sanguinea, Cycloneda pulchella, Eriopis connexa and Hippodamia convergens larvae, as well as eggs predation rate. Two treatments were used: absence and presence of...

Autores: Krinski,Diones; Favetti,Bruna M.; Leite-Junior,Admar F.; Silva-Gomes,Izabela T.
Aiming to contribute to a rearing methodology for the brown stink bug, Euschistus heros, in the laboratory, we evaluated oviposition on artificial substrates of different colors. During six days, oviposition was evaluated daily, by counting the total number of eggs, number of clutches, and eggs/clutch. Females laid 12,463 eggs, in 1,677 clutches, resulting in an average of 7.28 ± 0.44 eggs/clutch. Black, brown, and green felt had the most eggs and clutches. The results demonstrated that many colors are suitable as oviposition substrate for E. heros, providing information for the mass rearing of this insect.

Autores: Fernandes,Elania; Araujo,Elton; Souza,Itala; Souza,Mariana; Nunes,Glauber.
ABSTRACT The gregarious endoparasitoid Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a natural enemy of fruit flies. This parasitoid was previously used to successfully control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Hawaii, USA. Despite its importance in the control of fruit fly pests, little is known about the development or characteristics of its preimaginal stages. The aim of this study was to observe the development and morphologically characterize the immature stages of Tetrastichus giffardianus. Tetrastichus giffardianus individuals were reared on C. capitata larvae/pupae under laboratory conditions at a temperature of 25 ± 2 °C, relative humidity of 60 ± 10%, and 12-h photophase. Third-instar C. capitata larvae...

ABSTRACT The coffee berry borer Hypothenemus hampei Ferrari, 1876 (Coleoptera: Curculionidae: Scolytinae) is considered the most serious pest of the coffee crop and is controlled primarily with the use of chemical insecticides. An alternative to this control method is the use of the entomopathogenic bacterium, Bacillus thuringiensis Berliner, 1911. Therefore, the objective of this work was to select strains of B. thuringiensis virulent against H. hampei and characterize them by morphological and molecular methods to identify possible genes for the production of genetically modified plants. To achieve this objective, 34 strains of B. thuringiensis underwent a selective bioassay to evaluate their toxicity to H. hampei first-instar larvae. Among the strains...

Autores: Pratissoli,Dirceu; Bueno,Adeney de Freitas; Bueno,Regiane Cristina Oliveira de Freitas; Zanúncio,José Cola; Polanczyk,Ricardo Antonio.
It was studied the parasitism capacity of Trichogramma acacioi on Anagasta kuehniella and Sitotroga cerealella eggs at different temperatures (15, 20, 25, 30 and 35 ± 1°C). The parasitism of T. acacioi varied with temperature and host. The highest parasitism (³80%) were observed during the first days after emergence in both hosts, at all tested temperatures. The accumulated parasitism varied with both host and temperature, being higher on A. kuehniella at 20°C, what shows good parasitoid species adaptation to this temperature. Thus, we conclude that the best host and best temperature to be used at mass-rearing of T. acacioi is A. kuehniella and 20ºC, respectively. Moreover, this Trichogramma species has great potential to be used in field releases at...

Effects of parasitoid and host age on the parasitism of Trichogramma pretiosum on eggs of Anticarsia gemmatalis
Provedor de dados: 92
Autores: Queiroz,Ana Paula de; Costa,Cintia Oliveira; Favetti,Bruna Magda; Silva,Gabriela Vieira; Bueno,Adeney de Freitas.
Abstract The ages of parasitoid females and their hosts can have substantial effects on parasitism and parasitoid efficacy. This relationship has been investigated over the last few decades and found to vary among species. To our knowledge, it was virtually unknown for Trichogramma pretiosum wasps that parasitize Anticarsia gemmatalis eggs. Therefore, the influence of parasitoid and host age on the parasitism of T. pretiosum on eggs of A. gemmatalis was here evaluated in three independent bioassays. Neither the number of parasitized eggs nor that of emerged parasitoids differed between T. pretiosum females of different age. The number of parasitoids per egg and the sex ratio were higher for 5-day-old females. Regarding host age, the number of parasitized...

Will the Convention on Biological Diversity put an end to biological control? Under the Convention on Biological Diversity countries have sovereign rights over their genetic resources. Agreements governing the access to these resources and the sharing of the benefits arising from their use need to be established between involved parties. This also applies to species collected for potential use in biological control. Recent applications of access and benefit sharing principles have already made it difficult or impossible to collect and export natural enemies for biological control research in several countries. If such an approach is widely applied it would impede this very successful and environmentally safe pest management method based on the use of...

The avocado fruit borer, Stenoma catenifer (Wals.) has been a limiting factor in growing avocados over the last years in many Brazilian states. This is a result of the lack of safe and feasible management practices to minimize the fruit borer damage. The aim of this study was to obtain information on the pest biology and ecology as well as on the role of natural enemies to define strategies to control the pest. Samples were taken biweekly and consisted of 20 fruits collected randomly (10 from the upper half and 10 from the lower half of the plant) in ten plants, cv. Margarida, in a commercial avocado grove in Arapongas and Cambé regions, PR, from October/2001 to September/2002. Laboratory determinations of the percentage of damaged fruit per plant region,...

Parasitism on Eriosoma lanigerum (Homoptera: Aphididae) by Aphelinus mali (Hymenoptera: Encyrtidae) on apple orchards, in Fraiburgo county, state of Santa Catarina, Brazil
Provedor de dados: 94
Autores: Monteiro,Lino Bittencourt; Souza,Alexander; Belli,Edson Luiz.
The parasitism of the woolly apple aphid (Eriosoma lanigerum Hausmann) by Aphelinus mali (Hald.) was evaluated in apple orchards cultivated with the varieties Gala and Fuji in Fraiburgo County, State of Santa Catarina, Southern Brazil. Colonies of the woolly apple aphid were evaluated during one year on 16 apple trees of each variety, starting in August 1999. The number of aphids at the mummy stage or presenting the orifice of the parasitoid emergence was recorded. Results have shown that A. mali parasitized more than 50% of the woolly apple aphids and occurred during the four seasons. It was concluded that that under these conditions no chemical control against the aphid is necessary for the apple varieties Gala and Fuji.

Abstract  Black fly is a pest of Asian origin that causes direct and indirect damages to citrus, damaging the development and production of plants. For the development of efficient management strategies of the pest, the integration of control methods is necessary, and biological control is the most appropriate. Among the agents that can be used, entomopathogenic fungi are considered one of the most important and wide-ranging use. This work investigated the occurrence of Purpureocillium lilacinum (Thom.) Luangsa-ard et al. (= Paecilomyces lilacinus), attackingnymphs of citrus black fly, Aleurocanthus woglumi Ashby (Hemiptera: Aleyrodidae).

Ceraeochrysa caligata (Banks, 1945) is one of the several species of Ceraeochrysa Adams, 1982 that occur in agroecosystems of the Neotropical region and show potential for use in biological control programs. However, little is known about its biology, partly because of the poor status of the systematics of this group. To help in the identification of C. caligata and to contribute with additional characters for future phylogenetic studies with the genus, here we characterize the variations in relation to the pattern of integument markings originally described for the adults and larvae and redescribe the three larval instars, including characters not considered in the original description, especially the number of setae in the tubercles and somatic segments....

Some aspects of Meloidogyne spp. (root-knot nematode) growth regulation by the gram-negative bacterium Pasteuria penetrans were reviewed. The study allowed the construction of a mathematical model to predict the dynamics of both organisms. The model includes 11 differential equations and 31biological constants describing the life-cycle of the nematode and its relationship with the bacterium. To simulate the real behavior of the populations, the constants, which represent biological parameters, have to be evaluated under controlled conditions similar to those of soil microcosm.

Autores: Grassbaugh,E. M.; Bennett,M. A.
Several factors can influence stand establishment in vegetable crop production. Environmental conditions such as soil physical characteristics, temperature and moisture, various cultural practices, and diseases may all be limiting factors in establishing maximum stands and achieving the highest possible yields. Measures taken to increase stands include soil improvements, implementing cultural practices, and use of chemical and biological seed treatments. Combining seed treatments and cultural/tillage practices to minimize environmental constraints can lead to maximum stands and yields in the production of high quality vegetable crops.

Diatraea saccharalis (Fabr.) (Lepidoptera: Pyralidae) spends the largest part of its life cycle inside the stalk of the host plant,which provides protection against the action of conventional control methods. Biological control has been considered a viable alternative to control this pest in sugarcane (Saccharum officinarum L.) and corn (Zea mays L.), two pest preferential hosts. This paper reports the occurrence in Brazil of Tetrastichus howardi (Olliff) (Hymenoptera; Chalcidoidea: Eulophidae) parasitizing pupae of D. saccharalis obtained from corn plants. It also includes preliminary biological data about the insect. A single female of T. howardi is able to produce up to 66 offspring using a single pupa of the host D.

Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) is considered to be the main pest of maize crops in Brazil. Entomopathogenic nematodes (EPN) may be used to control this pest and exhibit different, unique abilities to search for their hosts. The movement of EPN in relation to S. frugiperda was evaluated. To test for horizontal movement, a styrofoam enclosure filled with sand was divided into segments, nematodes were placed at the entrance to the enclosure and a larva was placed at the end of each division. The same approach was used to evaluate vertical movement; however, PVC pipes were used in this case. In general, the mortality was inversely proportional to the initial distance between host and nematodes. In the vertical displacement test,...

Autores: Tironi,Paulo; von Treuenfels,Adrian; Parra,José Roberto Postali.
Cyrtomon luridus (Boh.), a native insect of wild Solanaceae, has adapted to the medicinal plant Duboisia sp., introduced from Australia, causing damages up to 100% mortality. Microctonus sp. is the most important natural enemy of C. luridus and its potential for biological control was investigated in this work. This study was carried out in Arapongas, Paraná State, Brazil, from 1994 to 1996. Parasitism of C. luridus by Microctonus sp. was highest from February through June (maximum of 54% in May 1996), when the C. luridus adult population was decreasing. The female sex ratio of Microctonus sp. under natural conditions was 0.57 to 0.69, which was close to 1 male : 2 female. Production of males occurs parthenogetically (arrhenotoky). In the laboratory,...

ABSTRACT: The banana moth Opogona sacchari (Bojer) (Lepidoptera: Tineidae) is a polyphagous pest that can cause serious damage, especially to banana crops in southern Brazil. It attacks the fruit, lowering its quality and making bananas unsuitable for export. Current control measures are limited and the use of Trichogramma (Hymenoptera: Trichogrammatidae) for Applied Biological Control may be an alternative for the management of this pest. In this study, we investigated the potential parasitism effectiveness of eggs of O. sacchari by T. pretiosum, T. atopovirilia and T. galloi, three species of parasitoids commonly used in Applied Biological Control programs in Brazil. Eggs of O. sacchari were parasitized by all three Trichogramma species, and T....

Autores: Wynns,Anja Amtoft; Jensen,Annette Bruun; Eilenberg,Jørgen; Delalibera Júnior,Italo.
ABSTRACT: The citrus scale insect Praelongorthezia praelonga (Douglas), a major pest of citrus and other economically important crops, has only two commonly documented natural enemies: an entomopathogenic strain of the fungus Colletotrichum nymphaeae (Pass.) Aa and several parasitoids. The entomopathogenic strain of C. nymphaeae, formerly recognized under the synonym C. gloeosporioides f. sp. ortheziidae, is under development for commercial application as a biological control agent in citrus in Brazil-the top exporter of citrus globally. The synonomy of C. gloeosporioides f. sp. ortheziidae with C. nymphaeae remains based on limited DNA sequence data and without morphological study. To qualify for future approval as a biological control agent by federal...

The citrus leafminer, Phyllocnistis citrella (Gracillariidae), is among the main pests of citrus in Brazil. The objective of this work was to conduct a survey of parasitoids attacking CLM in Jaguariúna, State of São Paulo, Brazil, before and after the introduction of Ageniaspis citricola (Encyrtidae). Collections of new leaves were made weekly at citrus groves from July-1997 to April-1999. During the survey period, A. citricola was introduced in the area. Before this introduction, Galeopsomyia fausta (Eulophidae) was the predominant species (about 91.83% of the species composition), but A. citricola became predominant after its establishment (60.10% against 38.30% G. fausta). Other parasitoids found were Cirrospilus sp. C (Eulophidae), Horismenus sp....

ITS and RAPD analyses were used to investigate molecular variations within samples of Paecilomyces isolates and to resolve five morphologically atypical isolates resembling P. fumosorosus, obtained from whitefly in Northern Paraná State. The ITS4-ITS5 amplicon was 700 base pairs (bp) long in all isolates. The five isolates of Paecilomyces not assigned to species produced restriction profiles identical to all the reference strains of P. fumosoroseus. The extent of fingerprint variability observed by RAPD was sufficient to discriminate all the isolates. The genetic similarity among unidentified isolates and strains of P. fumosoroseus was even higher than that observed among reference strains of this species, allowing us to conclude that isolates CNPso-P77,...

Impact of the number of Spodoptera frugiperda egg layers on parasitism by Trichogramma atopovirilia
Provedor de dados: 63
Autores: Beserra,Eduardo Barbosa; Parra,José Roberto Postali.
Egg parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) can be found in several crops attacking Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) eggs. It is therefore necessary to demonstrate the capacity of these natural enemies in suppressing populations of the pest to allow them to be used in biological control programs against that species. This work had the objective of evaluating the impact of egg layer distribution in S. frugiperda egg masses on the parasitism capacity of Trichogramma atopovirilia Oatman &amp;amp; Platner, 1983. Masses containing one, two, and three layers were used as treatments, and 1.6 parasitoid per egg of the pest were released. Parasitism percentage differences were observed among the three...

Autores: Pereira,Alexandre Igor de Azevedo; Ramalho,Francisco de Sousa; Zanuncio,José Cola.
Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) is an important biological control agent of the cotton leafworm [Alabama argillacea (Hübner)] in the cotton crops in Brazil. The use of selective products such as pyrethroids has been emphasized in this agroecosystem. Then, the susceptibility of the predatory stinkbug P. nigrispinus to the pyrethroid insecticide gamma-cyhalothrin was studied in the laboratory. Nymphs and adults of the predator were exposed to seven concentrations of the gamma-cyhalothrin via topical contact and ingestion through treated water. The concentrations studied of this insecticide via topical application were relatively harmless for adults of P. nigrispinus (females: LC50 = 143.5 ppm a.i., and males: LC50 = 145.1 ppm a.i.)...

Climatic similarity has been the primary parameter considered in the selection of sites for the collection and release of natural enemies in classical biological control programs. However, acknowledging the relevance of the composition of biological communities can be essential for improving the record of successful biocontrol projects, in relation to the proper selection of collection sites. We present in this paper an analysis of the plant and mite assemblages in cassava fields of northeastern Brazil. Such analysis is suggested as an additional criterion for the selection of collection sites of mite predators of the cassava green mite, Mononychellus tanajoa (Bondar), in an international biological control program. Contingency TABLES were built using...

Abstract Several species of Synopeas Forster (Hymenoptera: Platygasteridae) are parasitoids of gall midges and bud (Diptera: Cecidomyiidae) worldwide. In Neotropical region, the bud Prodiplosis longifila Gagné causes severe economic losses, particularly in tomato (Solanum lycopersicum L.) crops. Prodiplosis longifila is found in North and South America, and it is a potentially invasive species that is also found throughout Caribbean Islands. To diminish the impact of P. longifila on crops and to delay its geographical expansion it is necessary to identify its natural enemies and to improve its biological control. As a first step in this direction, in this study, four species of Synopeas: S. aff. curvicauda, S. aff. longiventre, S. reticulatifrons and S....

ABSTRACT Termites of the Nasutitermes genus are considered one of the main urban and agroforestry pests in Brazil, where the main method of control is the application of pesticides. The uso of entomopathogenic fungi to reduce the population of this plague in the environment could be use as an alternative. The goal of this study was to evaluate the virulence of isolates native Amazonian fungi belonging to the Tolypocladium endophyticum, Metarhizium anisopliae and Metarhizium marquandii species for the control of Nasutitermes sp. The strains of T. endophyticum (4.439), M. anisopliae (4.443) and M. marquandii (4.472) with their respective isolation codes, were evaluated using suspensions at concentrations of 105, 106, 107 and 108 conidia/mL against the...

ABSTRACT Endophyte microorganisms have great biotechnological interest, with features applicable to different areas and are potentially useful in agriculture. The current study determines the biotechnological potential of endophytic fungi, isolated from leaves of Sapindus saponaria, to control phytopathogenic fungi and evaluate their enzyme production. Molecular taxonomy was performed by sequencing of the ITS1-5.8S-ITS2 ribosomal DNA region, identifying the genera Phomopsis, Sordariomycetes, Diaporthe, and Colletotrichum. In vitro antagonism against phytopathogens showed better results against Fusarium solani and provided inhibition indices between 41.8 % and 67.5 %. The endophytic strain SS81 (Diaporthe citri) presented the highest antagonism index...

ABSTRACT Bactrocera carambolae Drew &amp; Hancock is a quarantine pest present in Brazil and is the main phytosanitary barrier for the export of fresh fruits from that country. In this work, we evaluated the effect of Amazonian isolates of Metarhizium on kill larvae, pupae, and adults of B. carambolae in soil applications. The mortality of larvae and pupae in sterile soil treated with Metarhizium anisopliae was 70 %. In addition, 100 % of the adults that emerged from this substrate died up to five days later. This isolate caused the mortality of larvae and pupae in non-sterile soil, but its effect was more evident after adult emergence (70 % mortality up to ten days after emergence). Metarhizium robertsii was effective in killing larvae and pupae of the...

Autores: Soares, Flávia Barbosa; Monteiro, Antonio Carlos; Babosa, José Carlos; Mochi, Dinalva Alves.
This study investigated whether populations of naturally-occurring soil bacteria, fungi and actinomycetes influence the effect of fungicides on the survival and growth of Beauveria bassiana. The toxicity of methyl thiophanate, pyraclostrobin, mancozeb and copper oxychloride at the recommended doses was analyzed in culture medium and in soil inoculated with fungus at various time points after addition of fungicides. All fungicides completely inhibited the growth and sporulation of B. bassiana in the culture medium. The fungicides were less toxic in soil, emphasizing the action of the microbial populations, which interfered with the toxic effects of these products to the fungus. Actinomycetes had the greatest influence on the entomopathogen, inhibiting it or...

Abstract: The sugarcane borer, Diatraea saccharalis is one of the hosts more used for parasitoid pupal multiplication in Brazil. The parasitoids pupal of Trichospilus diatraeae and Palmistichus elaeisis are generalist natural enemies with potential to suppress populations of diverse families of lepidopteran pests. The success in the utilization of these natural enemies in the field is directly related to the capacity of search of the host, this capacity might be affected by the presence of the pathogens. In this context, the aim of this essay was to detect the presence of intracellular parasites of Phylum Microsporidia. These pathogens may cause morphological and behavioral alterations. The presence of infection was verified by microscopy and was confirmed...

Provedor de dados: 42
Autores: CAVALCANTI,VYTÓRIA P.; ARAÚJO,NEILTON A.F.; SCHWANESTRADA,KÁTIA R.F.; PASQUAL,MOACIR; DÓRIA,JOYCE.
Abstract Garlic (Allium sativum L.) plays an important role in popular culture due to its dietary and medicinal uses. It is also used to produce a wide range of pharmacologically interesting molecules. Several pathogens affect garlic plants, especially Athelia (Sclerotium) rolfsii, a fungus that is widespread and causes large economic losses. It causes direct damage to crops and leads to plant stress, which induces secondary metabolite production in plants. The use of microorganisms as biocontrol agents may induce the production of beneficial metabolites in plants that will protect it and promote resistance to pathogen attack. In addition to suppressing disease, biological control agents may have elicitor effects that could induce an increase in the...

Abstract  The objective of this study was to evaluate the influence of wing bands and the behavior of Anastrepha fraterculus in the presence of Megafreya sutrix. The first experiment used specimens of M. sutrix (n = 40), 20 males and 20 females of A. fraterculus and Musca domestica. The second experiment used 20 individuals of M. sutrix (10 males and 10 females) and 120 of A. fraterculus (20 males and 20 females) for each treatment. Marks were made on the wings of the flies: a group with painted wing bands (n = 40) with their wings fully painted; another with highlighted wing bands (n = 40) and normal bands (n = 40). Recordings were made for 15 min or until the fly was preyed upon. The analyses were performed through observation of the recordings and...

Provedor de dados: 42
Autores: COURI,MÁRCIA S.; SOUSA,VIVIANE R. DE; LIMA,RAFAEL M.; DIAS-PINI,NIVIA S.
ABSTRACT Coenosia attenuata Stein (1903) is a predatory fly that is commonly found in greenhouses and open fields preying on whiteflies, leafminers, psocopterans and other insects. The species is widespread in the Old World and its distribution has expanded in recent times to Neotropical countries including Chile, Colombia, Costa Rica, Ecuador and Peru. We report here for the first time the presence of C. attenuata in Brazil, occurring in different sites in the State of Ceará (Northeastern Brazil). Expansion of the distribution range of this muscid to the eastern parts of South America opens up the possibility of applying the beneficial predator as a biological control agent for protected crops of the region.

ABSTRACT This paper records the first report of Megastigmus transvaalensis Hussey (Hymenoptera: Torymidae) in Brazilian peppertree, Schinus terebinthifolius Raddi (Anacardiaceae) drupes in Sorocaba, state of São Paulo, Brazil. This wasp is an invasive species and was found damaging S. terebinthifolius drupes in urban areas (35.0±15.8%), natural forests (21.5±10.2%) and restoration areas (15.8±8.4%). The bio-ecology and damage caused by M. transvaalensis in the S. terebinthifolius drupes warrants further study focused upon the management of this phytophagous wasp. Megastigmus transvaalensis has a potential to be disseminated throughout Brazil and is posing a threat to the natural regeneration of S. terebinthifolius in the native forests and restoration...

The knowledge on ovigeny in parasitoids is important for basic studies on physiology and applied biological control. The ovigeny pattern and type of ovariole of the parasitoid Palmistichus elaeisis Delvare &amp;amp; LaSalle (Hymenoptera: Eulophidae) were studied in newly-emerged females at seven, 14, 24 and 48 h intervals after their emergence from Tenebrio molitor L. pupae (Coleoptera: Tenebrionidae). Females of P. elaeisis presented ovaries composed by four ovarioles of the meroistic polytrophic type. The yolk accumulation and chorionogenesis in P. elaeisis were concluded 24 h after the female emergence. The 48 h-old females show a high quantity of egg ready for oviposition. These findings can help to improve the mass production of P. elaeisis and the...

Autores: Mendonça,Fernando A. C.; Barreto,Marliton R.; Assis Jr.,Sebastião; Marsaro Jr.,Alberto L.
The mating behavior of the predator Supputius cincticeps (Stal) was investigated in the laboratory. Courtship and copulation descriptions were based on direct observations of 40 virgin couples. Results showed that males begun courtship by moving the antennae and walking toward females, immediately after they noticed their presence. Then, males mounted females and tried to copulate. In many cases, males were rejected by females. When copulation was successful, males placed the edeagus into females, turned 180º and assumed a position opposite to the female.

Autores: Medeiros,Maria A.; Schimidt,Francisco V.G.; Loiácono,Marta S.; Carvalho,Vinícius F.; Borges,Miguel.
The mortality of Euschistus heros (F.) at the egg stage was studied at the field. The experiments were carried out in Planaltina - D.F., Brazil, in 1993 and 1994, on sunflower (Helianthus annuus) cultivated following the soybean (Glycine max) crop season. Egg masses found in the field were marked and checked daily for four days, and taken to the laboratory to check the total number of eggs, eggs that failed to hatch and those parasitized or destroyed by predators. The incidence of parasitism in eggs of E. heros was high in 1993 (65%) and in 1994 (80%). Five species of parasitoids were recovered: Telenomus podisi Ashmead, Trissolcus basalis (Wollaston), Trissolcus teretis Johnson, Trissolcus urichi Crawford (Scelionidae) and Eupelmus sp.

Provedor de dados: 44
Autores: Cruz,Ivan; Figueiredo,Maria L. C.; Valicente,Fernando H.; Oliveira,António C.
Different concentrations of nuclear polyhedrosis virus were applied as aqueous suspensions using a tractor mounted or a backpack-manual sprayer to control Spodoptera frugiperda (Smith) larvae on maize (Zea mays L.). Larval mortality varied with the application equipment. For the tractor-mounted sprayer application of at least 2.5 x 10(12) P.I.B./ha was necessary to attain a control comparable to that obtained with the backpack-manual sprayer application (70.2%). For this application method it can be used the dose of 2.5 x 10(11) PI.B./ ha, butNPV persistence was very short. A greaterNPV persistence was obtained with doses over 1.25 x 10(12) P.I.B./ha (93.4% mortality). The occurrence of parasitoids in the experimental area increased larval mortality rate...

Autores: PÉREZ,LUZ MARÍA; BESOAÍN,XIMENA; REYES,MAURICIO; PARDO,GONZALO; MONTEALEGRE,JAIME.
Four isolates of Trichoderma harzianum (ThN3, Th11, Th12 and Th16) were selected for their ability to control the in vitro development of the tomato root pathogen Pyrenochaeta lycopersici. Analysis of the mechanisms involved in biocontrol showed that the formation of non-volatile metabolites appears to be one of those involved in biocontrol of P. lycopersici by all T. harzianum isolates tested. Nevertheless, the higher secretion of chitinases, both in number of isoenzymes and activity by the Th11 strain, correlated well with its higher ability to control this agent in laboratory and greenhouse experiments as compared to the other T. harzianum isolates tested. The secretion of ß -1,3-endoglucanases and/or proteases appeared to have less significance than...

Patches of natural vegetation have been reported to play an important role in the preservation of diversity of natural enemies of pest arthropods. Euphorbiaceous plants are common in natural and regenerated ecosystems in the State of São Paulo. Those plants may act as reservoirs of phytophagous mites and their respective natural enemies, both of which are also found on cultivated plants of the same family. The objective of the work reported in this paper was to study the diversity of mite species on euphorbiaceous plants in three regions of the State of São Paulo, and to compare the similarities between those regions in relation to the composition of the mite fauna they harbor. A total of 31,603 mites belonging to 105 species in 74 genera and 16 families...

In an effort to devise a biological strategy to control guava decline, 120 rhizobacteria isolates were obtained from symptomless guava trees located in Meloidogyne enterolobii-infested orchards. Of those isolates, 44 were assessed for their potential to reduce nematode's reproduction: for each isolate, six guava stem cuttings were embedded for eight hours with bacterial suspension and transplanted. Upon development of the roots, the plants were inoculated with 2000 nematode eggs and allowed to grow for four months under greenhouse. Seedlings embedded with water, inoculated or not with the nematode, served as controls. All treatments were equivalent in the five variables that assessed plant development. Several rhizobacteria reduced (p&lt;0.05) the final...

Provedor de dados: 53
Autores: Dinardo-Miranda,Leila Luci; Fracasso,Juliano Vilela; Costa,Viviane Pereira da; Lopes,Diego Olympio Teixeira.
Diatraea saccharalis Fabr. (Lepidoptera: Crambidae) is a major sugarcane pest in Brazil. The management of infested areas is based on the release of Cotesia flavipes (Cameron) (Hymenoptera: Braconidae), a parasitoid of D. saccharalis larvae, but there are doubts about the effectiveness of C. flavipes, primarily regarding its rate of dispersal in sugarcane fields. Thus, the objective of this study was to evaluate the dispersal of C. flavipes in a sugarcane field and suggest a release method that provides higher parasitoid efficiency. The study was carried out in four areas of approximately 1 ha, in which stalk pieces containing 20 D. saccharalis larvae were distributed in a rectangular grid, and 12,000 C. flavipes adults were released at four points, that...

Functional response of the predator Eriopis connexa (Coleoptera: Coccinellidae) to different prey types
Provedor de dados: 52
Autores: Sarmento,Renato Almeida; Pallini,Angelo; Venzon,Madelaine; Souza,Og Francisco Fonseca de; Molina-Rugama,Adrián José; Oliveira,Claudinei Lima de.
This work evaluated the functional response of adult females of Eriopis connexa to different densities of Macrosiphum euphorbiae and Tetranychus evansi. When preying upon aphids, E. connexa presented a sigmoidal functional response (Type III). This behavior, however, changed drastically to an exponential (Type II) functional response, when mites (T. evansi), rather than aphids, were offered to E. connexa. Such different patterns showed that this coccinellid needed to adopt distinct strategies according to the kind of prey available. Since predators were believed to be able to regulate prey populations only when adopting Type III functional response. E. connexa would be a good candidate for a biological control agent of M. euphorbiae, but would not suppress...

Autores: Azevedo,Dihego de Oliveira; Zanuncio,José Cola; Zanuncio Jr.,José Salazar; Martins,Gustavo Ferreira; Marques-Silva,Solange; Sossai,Marcos Franklin; Serrão,José Eduardo.
The aim of this work was to study the feeding habits of the predator Brontocoris tabidus (Heteroptera: Pentatomidae) analyzing the salivary gland complex (SGC). The SGC was dissected and subjected to histological analyses and biochemical assays. Results showed that a pair of bilobed principal salivary glands and one pair of tubular accessory salivary glands form the SGC and different parts of salivary gland synthesizes similar substances. Lipases, a-amylase and trypsin-like enzymes were detected at both lobes of the principal salivary gland. These data together with observations related to the predator's diet suggested that it could be considered an obligate zoophytophagous.

The tritrophic system hyptis suaveolens (Lamiaceae) - agromyzid leafminers (Diptera: Agromyzidae) - parasitoids (Hymenoptera): effects of herbivore density, host plant patch size, and habitat complexity on parasitism rate
Provedor de dados: 52
Autores: Queiroz,Jarbas Marcal de; Garcia,Maria Alice.
In this study a tritrophic system was evaluated to measure the contributions of the insect host density and its host plant concentration in simple and diversified habitat on the rate of parasitism. The system was composed of the plant Hyptis suaveolens, two species of agromyzid leafminers, and three morphospecies of parasitoids. The parasitism rate, patch size, and habitat complexity were found to be interdependent. If only the habitat complexity or patch size was take into account the differences in parasitism rate are not significant, although habitat diversity seemed to contribute more than the host plant concentration to increase the parasitism rate. The leaves or plants with different number of mines were equally attacked by the parasitoids. The...

Autores: Monteiro,Leila; Mariano,Rosa de Lima Ramos; Souto-Maior,Ana Maria.
The antagonism of eight Bacillus isolates was investigated against nine strains of Xanthomonas campestris pv. campestris (causal agent of crucifers black rot) to assess the role of lipopeptides in this process. Antimicrobial and hemolytic (surfactant) activity tests were performed in vitro using agar diffusion methods. Antibiosis and hemolysis were positive for four Bacillus isolates against all X. campestris pv. campestris strains. The correlation observed between antimicrobial and hemolytic activities indicated that lipopeptides were involved in the antibiosis mechanism of the studied antagonists. Fermentation studies were carried out with the isolates that showed highest antimicrobial and hemolytic activities, to follow up growth and production of...

Zoophytophagy in predatory Hemiptera
Provedor de dados: 52
Autores: Torres,Jorge Braz; Boyd,David W.
Predaceous hemipteran feeding on different trophic levels have raised questions about their ecology and role in biological control. Therefore, specific adaptations allowing them to simultaneously use plants and animals as sources for their nutritional requirements are important. Enzymatic variability in predatory hemipterans has been suggested as the basic adaptation for convergent or divergent to omnivory. Thus, the salivary enzymatic complexes of predatory hemipterans have been furnished a partial understanding of the mechanisms permitting switching between plant and animal food sources. In this study, a discriminatory analysis was performed to attribute trophic habits to each insect investigated based on the presence and absence of salivary enzyme...

Autores: Santos,Miriam Langner dos; Berlitz,Diouneia Lisiane; Wiest,Shana Leticia Felice; Schünemann,Rogerio; Knaak,Neiva; Fiuza,Lidia Mariana.
ABSTRACT The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. These bacteria can be found colonizing aerial parts or roots. This review aims to analyze the colonization strategies of endophytic bacteria through interaction with plants, as well as to highlight the metabolic influence of these organisms in plant tissues, which result in physiological and biochemical changes. Depending on the different mechanisms used internally to colonize a plant, these microorganisms are called obligate, facultative, or passive endophytes. Phytostimulation, biofertilization and biological control are mechanisms that...

The competition between populations of the parasitoids C. grandis and B. vulgaris was studied using larvae of Euscepes postfasciatus (Fairmaire) as an alternative host. A series of biological parameters was observed and related to the competitive abilities of both parasitoid species. They were capable of colonizing and maintaining their populations regardless of host location. The population growth of C. grandis and B. vulgaris, based on fecundity was not affected by the competition. The parasitism and survivorship to the adult stage were affected by competition, except when the host was located at the bottom of the rearing cage. C. grandis performed better than B. vulgaris independently of the competition and host location, but it did not exclude the...

Autores: Barboza,Deise Mari; Marques,Márcia Cristina Mendes; Pedrosa-Macedo,José Henrique; Olckers,Terence.
Solanum mauritianum Scopoli (Solanaceae), a native Brazilian shrub, has become naturalized and invasive in several countries. In South Africa, where invasions are severe, herbivorous insects that attack S. mauritianum in its native area have been considered for introduction as biological control agents. To assess the action of such herbivores on the plant, studies were carried out on a population of S. mauritianum in an area undergoing regeneration in southern Brazil. An analysis of the structure of that population was performed, as well as of herbivory by insects, in particular of Anthonomus (Curculionidae). The population structure showed an "inverted J" pattern in diameter classes, but not in height classes. Individual plants showed an aggregate...

The aim of this work was to test if egg viability of polyandrous females was increased with increasing number of matings. Longevity and reproductive output of females of the predatory stinkbug Podisus nigrispinus that were allowed to mate for 0, 1, 2, 3 times or were in the continuous presence of the same male was evaluated. Polyandry resulted in diminished sperm depletion. Females that had mated three times or that were in continuous presence of a male produced more offspring than females that mated once or twice throughout their lifetime. There was a negative correlation of mating history on female longevity. Results indicated that remating, either with same male or with different males were crucial for maximization of the reproductive success of females.

Autores: Lemos,Walkymário de Paulo; Ramalho,Francisco de Souza; Serrão,José Eduardo; Zanuncio,José Cola.
The morphology of the reproductive tract of Podisus nigrispinus (Dallas) females fed with Alabama argillacea (Hübner) larvae, artificial diet, Tenebrio molitor L. larvae or Musca domestica L. larvae were studied. The reproductive tract of females of this species presented yellow coloration and independent of the diet, each ovary had seven ovarioles joined through terminal filaments and forming a bunch shape structure. The histological data revealed that the ovary of P. nigrispinus was of meroistic telotrophic type, with each individual ovariole divided in a terminal filament, a tropharium (trophic chamber), a vitellarium, and a pedicel. The prey type affected the development and morphometry of these structures. Females of P. nigrispinus fed with 3rd or 5th...

Autores: Lange,Denise; Fernandes,Wedson Desidério; Raizer,Josué; Faccenda,Odival.
This study had the objective of assessing the differences in foraging activity of the predacious ants between two areas, one conventional and other with no-till agriculture systems. The research was conducted in two contiguous 1.5 ha plots in Dourados MS, Brazil, from February 2001 to December 2003. Each plot received 750 baits (Nasutitermes termites), 425 at daylight and 325 at night. The termites were placed on the filter paper, on the ground, and ant attack was monitored for 15 min, until removed. Sixteen ant species were found in the no-till system and nine in the conventional system. Baits removed from no-till were significantly higher than the conventional plots and were influenced by the sampling time, at day or night. The seasons of the year did...

Effect of host availability and egg load in Trichogramma platneri Nagarkatti (Hymenoptera: Trichogrammatidae) and its consequences on progeny quality
Provedor de dados: 52
Autores: Hohmann,Celso L.; Luck,Robert F.
Experiments were conducted to determine whether Trichogramma platneri Nagarkatti manifested a somatic-gametic trade-off and whether it was affected by host availability and host size. Large wasps produced on Trichoplusia ni Hübner and limited to five or 15 T. ni eggs daily, produced a similar number of progeny as wasps offered hosts from emergence. Similar results were obtained when they were deprived of T. ni eggs for one, three, five, or ten days and then provided with unlimited hosts daily until death. In contrast, small wasps produced from Sitotroga cerealella (Olivier) and deprived of T. ni eggs for one to three days suffered a significant reduction in progeny production. Regardless of size, the egg load of non-ovipositing wasps increased...

Autores: Santoro,Patricia Helena; Cavaguchi,Silvia Akimi; Alexandre,Talita Moretto; Zorzetti,Janaina; Neves,Pedro Manuel Oliveira Janeiro.
Trichoderma atroviride was tested in vitro for its sensitivity to different herbicides. The dosages tested were recommended dosage (RD), half dosage (½RD), and double dosage (2RD). Germination, colony-forming units (CFU), radial growth, and spore production were evaluated. Carfentrazone-ethyl and sulfentrazone inhibited the germination at RD and 2RD. A reduction in the CFU was observed for glufosinate-ammonium, atrazine, carfentrazone-ethyl, diuron + paraquat dichloride, imazapyr, oxyfluorfen, and sulfentrazone at each of the tested dosages. Radial growth was influenced by ametryn, atrazine, carfentrazone-ethyl, oxyfluorfen, and sulfentrazone herbicides, with an 80% reduction of the colonial area. Spore production was affected by carfentrazone-ethyl,...

Occurrence of Pyemotes sp. on Tuta absoluta (Meyrick)
Provedor de dados: 52
Autores: Oliveira,Carlos Romero Ferreira de; Matos,Cláudia Helena Cysneiros; Hatano,Eduardo.
The aim of this work was to study the population reduction of the tomato leafminer moth, Tuta absoluta (Meyrick), by Pyemotes sp. in the laboratory. The mite became greenish when fed on caterpillars, pupae, and adults of T. absoluta. The caterpillars and adults of T. absoluta were quickly paralyzed by the mite venom. A single T. absoluta could host many Pyemotes sp, physogastric females, which were allowed to grow on the moth. Pyemotes sp. can be a new alternative for the biological control of T. absoluta. However, this possibility must be better understood before it could be recommended, because Pyemotes sp. could also cause dermatitis in the humans.

Autores: Svedese,Virgínia Michelle; Lima,Elza Áurea de Luna Alves; Porto,Ana Lúcia Figueiredo.
The aim of this work was to evaluate the effect of temperature on the pathogenicity of Beauveria bassiana against Diatraea saccharalis and evaluate the horizontal transmission capacity among the sugarcane borer larvae. The strains were most pathogenic at 26ºC, followed by 32ºC than at 20ºC, with respective mortalities of 100, 50 and 30.3%. The lethal time was also affected by the temperature, with the shortest LT 50 observed at 26ºC (2.2 days) and the longest at 20ºC (16.2 days). The URM2915 strain appeared most effective in all the experiments as having potential for deployment in biological control programs for the sugarcane borer. Results in horizontal transmission of B. bassiana showed that this procedure could also be adopted as control strategy for...

Autores: Pratissoli,Dirceu; Oliveira,Harley Nonato de; Polanczyk,Ricardo Antonio; Holtz,Anderson Mathias; Bueno,Regiane Cristina Oliveira de Freitas; Bueno,Adeney de Freitas; Gonçalvez,José Roberto.
This work was carried out to study the effects of adult feeding and mating on the biological potential and parasitism of Trichogramma pretiosum and T. acacioi (Hymenoptera: Trichogrammatidae) to improve their use in biological control programs. Both species presented higher parasitism and longevity whenever adults were fed. Fed and unmated T. pretiosum females led to low parasitism whereas T. acacioi females did not present parasitism whatsoever. Egg viability of T. pretiosum was similar for fed and mated individuals, but T acacioi showed lower values for this parameter when unfed and without mating. Unmated females produced only males while mated ones had more than 60% female descendents for both Trichogramma species. Therefore, mated and fed female...

Biochar and Trichoderma harzianum for the Control of Macrophomina phaseolina
Provedor de dados: 52
Autores: Araujo,Alyson Silva de; Blum,Luiz Eduardo Bassay; Figueiredo,Cícero Célio de.
Abstract This study is based on the importance of biological control methods and the lack of information on the effect of biochar (BCH) from sewage sludge associated or not with Trichoderma harzianum on the control of Macrophomina phaseolina in the bean crop (Phaseolus vulgaris, cv. BRS Estilo). Biochar from sewage sludge, pyrolyzed at 500 ºC and used in low concentration (0.5%), has a direct effect on the in vitro control of M. phaseolina. However, higher BCH concentrations stimulated the growth of the pathogen. In culture medium with or without BCH, T. harzianum (strain 1306) inhibited the mycelial growth of M. phaseolina. The addition of BCH + T. harzianum reduced the deleterious effects caused by M. phaseolina on bean plants. This study demonstrated...

Autores: Mello,Renata da Silva; Borja,Gonzalo Efrain Moya; Coelho,Valéria Magalhães Aguiar.
To test the assumption that exposure of the host to parasitoid for long periods could provoke superparasitism, the aim of this work was to test the consequences on the immature development time, productivity of parasitoids per pupa, sex ratio and rate of parasitism of Nasonia vitripennis bred in Chrysomya megacephala pupae. Each individual pupa was placed in a glass tube with one parasitoid female for 24, 48, 72 and 96 h period of exposure, under controlled laboratory conditions. Twenty replicates of each period were performed. ANOVA with a 5% significance level was applied. The 72 h exposure caused the immature development time to increase. The mean parasitoids emergence per pupa did not vary significantly with the time of exposure. There were a...

Effect of Agaricus brasiliensis and Lentinula edodes mushrooms on the infection of passionflower with Cowpea aphid-borne mosaic virus
Provedor de dados: 52
Autores: Di Piero,Robson Marcelo; Novaes,Quelmo Silva de; Pascholati,Sérgio Florentino.
The objective of the present study was to evaluate the protection of passion fruit plants against CABMV by using preparations from Agaricus brasiliensis and Lentinula edodes mushrooms. In experiments carried out in the greenhouse, the fruiting body extracts from some of the isolates of both mushrooms significantly reduced CABMV incidence in passion fruit plants. This protective effect occurred when the plant leaves, pre-treated with extracts, were later inoculated mechanically with the virus. However, the extracts did not protect the plants in experiments involving CABMV transmission by aphid vectors. An inhibitory effect of mushroom extracts on the virus particles was also demonstrated on Chenopodium quinoa, a CABMV local lesion host, by inoculating the...

Autores: CÔNSOLI,F. L.; PARRA,J. R. P.; VINSON,S. B.
Mortality during the immature development of T. galloi and T. pretiosum was estimated on UV-killed and live eggs of a factitious and a natural host, respectively. A staining technique was used to determine the actual parasitization of UV-treated eggs and was compared with the number of parasitoids that emerged per host egg (detectable parasitization). Effects of temperature as a factor of mortality during the immature development of both parasitoids on the factitious host was also assessed. The actual and detectable parasitization of live hosts was measured by recording both the parasitization behavior and the number of eggs where a parasitoid developed successfully. Our data show that mortality during immature development of both parasitoids may occur in...

Provedor de dados: 58
Autores: Mota,Marcelo de Andrade; Campos,Artur Kanadani; Araújo,Jackson Victor.
Biological control is based on the use of microorganisms to combat populations of a specific pathogen. Nematophagous fungi have shown to be promising agents to combat nematode parasites of plants and animals. These organisms produce special structures along the hyphae, named traps, which are responsible for capturing and killing the nematode pre-parasitic stages. The growth of the isolates I31 of Arthrobotrys robusta and NF34a of Monacrosporium thaumasium was studied after submission to four different methods of preservation during eighteen months. The isolates were stored at 4ºC and cryopreserved with or without addition of cryoprotectants and stored in silica gel. The isolates did not present variation in radial growth when stored at 4ºC and frozen with...

Biological control consists of using one organism to attack another that may cause economic damage to crops. Integrated Pest Management (IPM) is a very common strategy. The white mold produced by Sclerotiniasclerotiorum (Lib.) causes considerable damage to bean crops. This fungus is a soil inhabitant, the symptoms of which are characterized by water-soaked lesions covered by a white cottony fungal growth on the soil surface and/or the host plant. Possible biological control agents taken from plants are being investigated as phytopathogen inhibitors. These are endophytic microorganisms that inhabit the intercellular spaces of vegetal tissues and are often responsible for antimicrobial production. The objective of the present study was to select endophytic...

Autores: Zanatta,Zarela G.C.N.; Moura,Andréa B.; Maia,Luciano C.; Santos,André S. dos.
Emphasis has been given on selection of micro-organism for biological control. However, in order to evaluate the biological control potential of a great number of micro-organisms in a small period of time it is necessary to develop an efficient bioassay. Seven hundred and sixty bacterial isolates from different habitats, were selected for compatibility with Rhizobium leguminosarum bv. phaseoli (SEMIA 4077 e SEMIA 4080). Among them 596 isolates were ineffective against both rhizobia. Bean seeds immersed in suspension of each one of these isolates were agitated for 5 hours at 10ºC and sowed in non-sterilized soil. The plants were kept in greenhouse. After the development of cotyledonary and primary leaves, these were removed and bioassayed for Xanthomonas...

Autores: Pimenta,R. S.; Silva,J. F. M.; Coelho,C. M.; Morais,P. B.; Rosa,C. A.; Corrêa Jr,A.
Our investigation of integrated biological control (IBC) started with an assay testing activity of the predacious yeast Saccharomycopsis crataegensis UFMG-DC19.2 against Penicillium digitatum LCP 4354, a very aggressive fungus that causes postharvest decay in oranges. Under unfavourable environmental conditions, the yeast showed a high potential for control (39.9% disease severity reduction) of this fungus. This result was decisive for the next step, in which S. crataegensis was tested in association with sodium bicarbonate salt, a generally regarded as safe (GRAS) substance. The yeast was able to survive at different concentrations of the salt (1%, 2% and 5%), and continued to grow for a week at the wound site, remaining viable at high population for 14...

Autores: Botelho,Gloria R.; Mendonça-Hagler,Leda Cristina.
Environmental concerns have led to the need of sustainable use of natural resources. The conventional agriculture caused considerable impacts on soils and waters. It is important to change certain agricultural managements to environmental cleaner techniques. The sustainable agriculture has pointed many approaches and techniques to reduce environmental impact. One of those strategies is the utilization of the soil microbiota to induce plant growth, control of plant diseases and biodegradation of xenobiotic compounds. Studies on the relationship between roots and microbiota are essential to achieve viable agricultural applications. These studies indicate that one of the most abundant microorganisms in the rhizosphere (area around the roots) is fluorescent...

Soils suppressive against Gaeumannomyces graminis var. tritici identified under wheat crop monoculture in southern Chile
Provedor de dados: 118
Autores: Andrade,Orlando; Campillo,Ricardo; Peyrelongue,Amelia; Barrientos,Leticia.
Improved knowledge of the biological phenomenon of soil suppressiveness is critical for the management and biological control of soil-borne pathogens. Andisols, which are located in southern Chile, show very high conduciveness to the take-all disease of wheat caused by the fungal soil-borne pathogen Gaeumannomyces graminis var. tritici. However, no previous reports have investigated suppressive soils in this important wheat-producing area. The first part of this study was conducted to identify soils suppressive to the take-all disease, and will be followed by a characterization of its microflora to identify potential bio-control agents against the fungal pathogen. Based on the transferability of suppressiveness into the same sterile soil background, 20...

Predatory capacity of Adalia angulifera (Coleoptera: Coccinellidae) larvae on Myzocallis coryli (Hemiptera: Aphididae) in Chile
Provedor de dados: 118
Autores: Aguilera,Alfonso; Neculmán,Rodrigo; Rebolledo,Ramón.
In La Araucanía, the filbert aphid Myzocallis coryli (Goeze) is a pest that can cause various types of damage to hazelnut (Corylus avellana L.) including reduction in nut size and nut emptiness. M. coryli can also leave hazel leaves susceptible to the fungus known as fumagina (Capnodium sp.), which causes decreased photosynthesis, particularly during the period when the tree is storing reserves for the following season. Knowledge about the natural enemies of M. coryli in Chile is in its early stages compared with other countries where the hazelnut crop is more extensive. Indeed, only 13 entomophagous predators have been recorded in La Araucanía thus far, including one Hemerobiidae, one Syrphidae, one Cecidomyiidae and ten Coccinellidae. Of this last...

ABSTRACT: This note is the first report on the infection of adult stage of Melanagromyza sojae Zehntner, 1900 (Diptera: Agromyzidae) by the entomopathogenic fungus Ophiocordyceps dipterigena (Hypocreales: Ophiocordycipitaceae) (Berk. &amp; Broome) G. H. Sung, J.M. Sung, Hywel-Jones &amp; Spatafora, in subtropical Brazil. Entomopathogenic fungi, which attack dipteran insects, are of great scientific and economic importance mainly due to their potential as biological control agents of insect pests. Our findings bring new perspectives on the geographical distribution and host range of Ophiocordyceps dipterigena. We emphasize the need of further studies and research on new biological control agents of agricultural pests such as the soybean stem miner fly.

Autores: Hoshino,Adriano Thibes; Bortolotto,Orcial Ceolin; Hata,Fernando Teruhiko; Ventura,Mauricio Ursi; Menezes Júnior,Ayres de Oliveira.
ABSTRACT: The infestation of coffee leaf miner and its predation by wasps were assessed in commercial organic coffee plantings shaded with leucaena or intercropped with pigeon pea. Plantings in northern Paraná were assessed every two weeks from June 2011 to December 2012. The percent of infested leaves, number of mines per leaf and the percent of predation by wasps (indicated by lacerations) were determined. Fewer coffee leaf miners and fewer mines per leaf were found in pigeon pea intercropped plantings (28.4% and 0.3, respectively) than in shaded plantings with leucaena (48.1% and 0.8, respectively).

Provedor de dados: 65
Autores: Nunes,Ana Rita Fonseca; Martins,Juliana Nascimento; Furlaneto,Márcia Cristina; Barros,Neiva Monteiro de.
Nomuraea rileyi represents an important natural control agent of Anticarsia gemmatalis preventing populations from reaching economic threshold levels in soybean. During the processes of host infection, entomopathogenic fungi produce extracellular proteases, which degrade the host cuticle and are suggested to be virulence determinants. It was examined the production of subtilisin-like (Pr1) and trypsin-like (Pr2) proteases in two strains (NR458 and CG434) of N. rileyi and its possible role in the process of pathogenicity to this caterpillar. Fungal growth was performed in a mineral medium containing nitrate, and supplemented with the cuticle or exuviae from A. gemmatalis, or with the non-cuticular substrate casein. In medium containing nitrate as sole...

Autores: Tiago,Patricia Vieira; Oliveira,Neiva Tinti de; Lima,Elza Áurea de Luna Alves.
Microbial control of insects is based on the rational use of pathogens to maintain environmentally balanced pest population levels, and Metarhizium anisopliae has been the most studied and most utilized fungal species for that purpose. The natural genetic variability of entomopathogenic fungi is considered one of the principal advantages of microbial insect control. The inter- and intraspecific variability and the genetic diversity and population structures of Metarhizium and other entomopathogenic fungi have been examined using ITS-RFLP, ISSR, and ISSP molecular markers. The persistence of M. anisopliae in the soil and its possible effects on the structures of resident microbial communities must be considered when selecting isolates for biological insect...

Autores: Blum,Luiz Eduardo Bassay.
Septoria leaf spot, caused by Septoria lycopersici, is an important disease of tomato (Lycopersicon esculentum) which is mainly controlled by fungicide sprays. One of the alternatives to reduce fungicide applications is the use of leaf antagonists such as yeast and bacterium. This study was conducted from 1994 through 1995 in Auburn, AL, USA. The pathogen and one antagonist were isolated from field plants. In greenhouse, six yeast and one bacterial isolates were tested, in a set of seven experiments. The experiments were conducted in a completely randomized design with four to eight treatments and six replications. The antagonists (1-3 × 10(8) colony forming units ml-1) were inoculated 48h before the inoculation of the pathogen (1-2 × 10(5) conidia ml-1),...

Telenomus remus releasing numbers may vary depending on the crop, plant architecture and/or the plant phenological stage. Thus, we examined the number of parasitoids needed for effective pest control of Spodoptera frugiperda on corn, cotton and soybean. In all crops, the parasitism response in relation to increasing numbers of the parasitoids had a quadratic effect. In corn, the maximum parasitism observed was 99.8% and 96.8% at a parasitoid releasing number of 0.231 and 0.264 T. remus females per S. frugiperda egg at phenological stages V4 and V10, respectively. Differently, in cotton and soybean, the highest parasitim were recorded using the highest tested T. remus releasing numbers (0.297 parasitoid per S. frugiperda egg). In cotton, it was 77.8% and...

ABSTRACT: Pesticides are considered the first line of defense for the control of pests and diseases. At least in the short and medium term, the use of pesticides will remain an important strategy for pest management, allowing growers to produce crops of sufficient quality at low costs. A broad approach known as Integrated Pest Management (IPM) combines several different pest-control strategies, among which the combination of chemical and biological control stands out. It requires pesticides that achieve optimal control of target pests with minimal impact on the activity of biological control agents. Because of the dynamics of pest infestations, IPM routines are continuously adjusted by growers, requiring comprehensive information about pesticide effects on...

The results of studies about interactions between microorganisms involving at least one plant pathogen are of interest to the areas of ethiology and control in Plant Pathology. Various aspects of these interactions have been studied over the years but the toxicity of volatile organic compounds (VOCs) has been emphasized only recently, developing techniques and procedures, and producing additional knowledge to those already obtained with water-soluble substances. This new facet of these interactions based on VOCs is discussed in this review involving mainly fungi, bacteria and nematodes pathogenic to plants. Also discussed is the role of VOCs produced by microorganisms, especially fungi and bacteria, in soil fungistasis and the effect of VOCs on fungal...
