Volcanism and arthropods: a review
Provedor de dados: 67
Autores: Elizalde,Luciana.
Volcanic eruptions are natural disturbances that impose multiple changes in ecosystems. Arthropods are among the most diverse organisms on the planet and play key functional roles in all ecosystems. Existing information on the effects of volcanic disturbances on arthropods is scattered. The aim of this review is to fnd generalities in the responses of arthropods from terrestrial and aquatic environments to volcanism. Mainly (1) what effects do volcanic disturbances have on arthropods?, (2) what characteristics make certain species more or less susceptible to volcanic disturbances?, and (3) how do arthropod communities reassemble after a volcanic disturbance? Terrestrial and aquatic arthropods show similar responses to volcanic disturbances. Volcanism can...

Temperature and the progeny sex-ratio in Sciara ocellaris (Diptera, Sciaridae)
Provedor de dados: 74
Autores: Nigro,Rogério G.; Campos,Maria Cristina C.; Perondini,André Luiz P.
We found that the sex-ratio of an amphigenic strain of Sciara ocellaris varied widely from progenies with few males to progenies containing a larger proportion of males, with single-sex progenies being rare. The sex-ratio distributions were dependent on the temperature at which the stocks of flies were raised, with the sex-ratio distributions being symmetrical (i.e. about 50% males) at 18 °C and 20 °C while at the higher temperatures of 24 °C and 28 °C the distributions were skewed toward a high proportion of females with the mean proportion of males decreasing to about 30-37% per progeny. Temperature-shift experiments showed that high temperatures were effective only during the last stages of female pupal development plus a period after adult emergence,...

Asymmetry of frontal bristles and postocular setae in species and hybrids of the Anastrepha fraterculus complex (Diptera, Tephritidae)
Provedor de dados: 74
Autores: Souza,João Maria G.A.; Gouveia,Milson; Perondini,André L.P.; Selivon,Denise.
Asymmetry of the frontal bristles and postocular setae was studied in samples from natural populations and laboratory colonies of Anastrepha sp. 1 aff. fraterculus, of A. sp. 2 aff. fraterculus, and in F1 hybrids obtained from laboratory reciprocal crosses. Natural populations were sampled in a zone of sympatry and in two geographically distant regions with different climatic conditions. Asymmetry was scored as the differences between the number of bristles and of setae on the right and left sides of the head, males and females analyzed independently. The two traits exhibited variability according to the model of fluctuating asymmetry (FA). No significant differences among samples were found in the FA of frontal bristles. A significant FA was observed for...

Provedor de dados: 14
Autores: OLIVEIRA, M. A. S.; SAMPAIO, J. B. R.; GOMES, A. C.
Este trabalho foi conduzido em Planaltina-DF, para verificar a flutuacao populacional do bicho-mineiro (Perileucoptera coffeella) no cafe variedade "Mundo Novo". As avaliacoes foram realizadas quinzenalmente, coletando-se, ao acaso, folhas de cafe do terco inferior, medio e superior. esse material, apos coletado, foi encaminhado ao laboratorio, onde se faziam as avaliacoes de: numero de lesoes por folha, lagartas vivas, mortas e percentual de infestacao. Os resultados obtidos permitem concluir que a parte alta da planta e a mais preferida para a oviposicao do bicho-mineiro; e a maior infestacao, ocorre nos meses de junho a outubro, coincidindo com o periodo de menor precipitacao pluviometrica, epoca em que se deve concentrar o controle de praga.

Durante dois anos, de junho/93 a maio/95, contagens de moscas-dos-chifres foram realizadas em dois rebanhos Nelore criados extensivamente na fazenda Nhumirim, sub-região da Nhecolândia, Pantanal, MS. Os rebanhos possuíam 40 e 60 vacas, mantidas sem tratamento inseticida durante o estudo. Contagens foram realizadas duas semanas consecutivas por mês, por observadores a cavalo, em pelo menos 50% dos animais em cada rebanho. Foram observados dois picos populacionais anuais da mosca, após o início (novembro/dezembro) e final (maio/junho) do período chuvoso. A presença de moscas foi observada durante todo o estudo, em pelo menos 64% dos animais. Infestações médias não excederam 85 moscas/animal e permaneceram abaixo de 35 moscas/animal na maior parte do estudo....

Recomendações para controle da mosca-dos-chifres no Pantanal.
Provedor de dados: 14
Autores: BARROS, A. T. M. de.
A Haematobia irritans chegou ao Pantanal no inicio de 1991. Em abril, ja havia sido reportada em varias propriedades nas sub-regioes da Nhecolandia e Paiaguas, e alcancava tambem os rebanhos proximos as cidades de Corumba e Ladario. Em pouco tempo verificou-se sua distribuicao por toda a planicie e a consequente necessidade de efetuar-se seu controle. O presente artigo objetiva fornecer ao produtor uma orientacao tecnica sobre o controle deste parasito, tendo sido baseado na observacao da mosca em seu primeiro ano de ocorrencia na regiao e na constatacao de infestacoes consideradas como significativamente prejudiciais a producao. De modo geral, recomenda-se a aplicacao de piretroides "pour-on" no inicio (outubro) e final (maio) da epoca chuvosa;...

Ácaros e insetos são responsáveis por consideráveis danos as mais diversas culturas em todo o mundo, tanto em condições de campo quanto em condições de armazenamento. Entretanto, um organismo pode ser uma séria de pragas dedeterminada cultura em uma região, e não causar dano algum a mesma cultura em outra região, dado que a importância de um ácaro ou inseto em determinada espécies vegetal varia de acordo com as condições ecológicas a que ele esta sujeito. Considerando-se a diversidade de culturas existentes na região do Sub-Médio São Francisco, os detalhes acerca do tipo de associação e dos danos causados por cada ácaro ou inseto em particular tomarão, ainda, algum tempo para serem esclarecidos.

Culture-Facilitated Comparative Genomics of the Facultative Symbiont Hamiltonella defensa
Provedor de dados: 5
Autores: Chevignon, Germain; Boyd, Bret M.; Brandt, Jayce W.; Oliver, Kerry M.; Strand, Michael R.
Many insects host facultative, bacterial symbionts that confer conditional fitness benefits to their hosts. Hamiltonella defensa is a common facultative symbiont of aphids that provides protection against parasitoid wasps. Protection levels vary among strains of H. defensa that are also differentially infected by bacteriophages named APSEs. However, little is known about trait variation among strains because only one isolate has been fully sequenced. Generating complete genomes for facultative symbionts is hindered by relatively large genome sizes but low abundances in hosts like aphids that are very small. Here, we took advantage of methods for culturing H. defensa outside of aphids to generate complete genomes and transcriptome data for four strains of...

Exposure to Conspecific and Heterospecific Sex-Pheromones Modulates Gustatory Habituation in the Moth Agrotis ipsilon
Provedor de dados: 5
Autores: Hostachy, Camille; Couzi, Philippe; Portemer, Guillaume; Hanafi-portier, Melissa; Murmu, Meena; Deisig, Nina; Dacher, Matthieu.
In several insects, sex-pheromones are essential for reproduction and reproductive isolation. Pheromones generally elicit stereotyped behaviors. In moths, these are attraction to conspecific sex-pheromone sources and deterrence for heterospecific sex-pheromone. Contrasting with these innate behaviors, some results in social insects point toward effects of non-sex-pheromones on perception and learning. We report the effects of sex-pheromone pre-exposure on gustatory perception and habituation (a non-associative learning) in male Agrotis ipsilon moths, a non-social insect. We also studied the effect of Z5-decenyl acetate (Z5), a compound of the sex-pheromone of the related species Agrotis segetum. We hypothesized that conspecific sex-pheromone and Z5 would...

Cultivation-Assisted Genome of Candidatus Fukatsuia symbiotica; the Enigmatic "X-Type" Symbiont of Aphids
Provedor de dados: 5
Autores: Patel, Vilas; Chevignon, Germain; Manzano-marin, Alejandro; Brandt, Jayce W.; Strand, Michael R.; Russell, Jacob A.; Oliver, Kerry M.
Heritable symbionts are common in terrestrial arthropods and often provide beneficial services to hosts. Unlike obligate, nutritional symbionts that largely persist under strict host control within specialized host cells, heritable facultative symbionts exhibit large variation in within-host lifestyles and services rendered with many retaining the capacity to transition among roles. One enigmatic symbiont, Candidatus Fukatsuia symbiotica, frequently infects aphids with reported roles ranging from pathogen, defensive symbiont, mutualism exploiter, and nutritional co-obligate symbiont. Here, we used an in vitro culture-assisted protocol to sequence the genome of a facultative strain of Fukatsuia from pea aphids (Acyrthosiphon pisum). Phylogenetic and genomic...

Consumption Rates and Performance of Erinnyis ello L. on Four Cassava Varieties
Provedor de dados: 82
Autores: BARRIGOSSI,JOSÉ A.F.; ZIMMERMANN,FRANCISCO J.P.; LIMA,PAULO S. DA C.
A laboratory experiment to determine the consumption rates of cassava (Manihot esculenta Crantz) and characterize the injury potential by Erinnyis ello L. was conducted. First instar larvae were individually reared on excised cassava leaves of four varieties. A randomized block design with nine replications was used. Fresh leaves were provided to the larvae daily. Leaf area was determined for each leaf before the leaves were provided to the larvae. Foliage consumption per instar, developmental time and weight of larvae and pupae were recorded. There were no significant differences in the larval consumption on the four varieties (P=0.82). Total leaf area consumption (square cm) for the varieties were: 1030.5 (Fio de Ouro), 971.5 (Aipim Bravo), 968.6...

Morphometric study of the midgut epithelium in larvae of Diatraea saccharalis Fabricius (Lepidoptera: Pyralidae)
Provedor de dados: 82
Autores: Pinheiro,Daniela O.; Silva,Reinaldo J.; Quagio-Grassiotto,Irani; Gregório,Elisa A.
The sugarcane borer, Diatraea saccharalis Fabricius, has great economical interest as it affects the culture and industrial use of the sugarcane. However, there are few studies concerning the internal morphology of this insect. This work aims to study morphometrically the midgut and the epithelium along their lenght, trying to characterize different regions. Midgut of last instar larvae was divided in three regions: anterior, middle and posterior, and the fragments were processed for light microscopic observation. Histological sections were analyzed in a computerized system concerning the length, width and area of the epithelium, their cells, and the midgut lumen. The obtained data were statistically analyzed by the Kruskal-Wallis test and by multivariate...

The stink bug complex in soybeans has a great potential to cause damage, their control has been difficult due to high population densities at the end of the season. Studies related to entomopathogenic organisms in stink bugs are interesting for their possibilities to be used as biological control agents and because they could be an etiological agent in mass rearing. We determined the prevalence of trypanosomatids in the most important species of the stink bug complex in soybean, from Brazil, Nezara viridula (L.), Euschistus heros (Fabricius) and Piezodorus guildinii (Westwood). Insects were collected in soybean and on alternate hosts during the intercrop season. Hemolymph drops from each adult were mounted on slides and observed under microscope; stink bug...

The dorsal and ventral branches of the secretory regions are connected via transverse commissures and ends in a loop. The secretory region is uniform and consists on a simple cubical epithelium. This paper also presents a review on the morphology of the salivary glands in insects, mainly in Hymenoptera-Aculeata.

Provedor de dados: 82
Autores: Santos,Daniela C.; Gregório,Elisa A.
Diatraea saccharalis F. is one of the greatest pests of the sugar cane culture. This report aimed to characterize the germarium region of the sugarcane borer by light and transmission electron microscopy, emphasizing the morphological steps of the ovarian cluster formation. In the germarium of this insect, four zones could be morphologically identified during the cluster formation. In the most apical end of each ovariole - Zone I - the germ line stem cells undergo complete mitotic division, originating the cystoblasts. In the Zone II, each cystoblast produces a group of eight cells, the cystocytes, which are interconnected by the ring canals. Clusters containing all the cystocytes in the meiosis, characterizes the Zone III. Germ cells with ultrastructural...

Insecticide resistance in populations of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), from the state of Pernambuco, Brazil
Provedor de dados: 82
Autores: Santos,VC; Siqueira,HAA de; Silva,JE da; Farias,MJDC de.
The diamondback moth Plutella xylostella (L.) has a great economic importance in Brassicaceae crops in many parts of the world. Recurrent infestations of this pest in growing areas of Pernambuco state, Brazil, have led farmers to frequently spray their crops with insecticides. However, control failures by several insecticides have been alleged by farmers. The objective of this study was to check whether resistance to insecticides could explain these control failures in P. xylostella. Populations of P. xylostella from Pernambuco were collected between January and April 2009. The resistance ratios of P. xylostella populations were compared among five different active ingredients: abamectin, methomyl, lufenuron, indoxacarb, and diafenthiuron by leaf dipping...

Autores: Fontellas,Tânia M.L.; Zucoloto,Fernando S.
Carbohydrates are the main source of energy for insects and the lack of these nutrients in the diet can cause serious damage to the biology of these arthropods. In order to better understand the effect of sucrose on the performance and dietary selection of adult Anastrepha obliqua (Macquart), the following experiments were carried out: 1) effect of different amount of sucrose on diet ingestion, longevity and egg production; 2) dietary selection that contains different amounts of sucrose, and 3) discrimination threshold for sucrose in adult individuals deprived or not of carbohydrates. The control diet showed the best results in relation to ingestion, longevity and egg production for these species, probably due to the fact that it presents an optimal...

Autores: Yun,Y; Peng,Y; Liu,FX; Lei,C.
Recent studies have revealed that the prevalence of Wolbachia in arthropods is attributable not only to its vertical transmission, but also to its horizontal transfer. In order to assess the horizontal transmission of Wolbachia between predator and prey, arthropods belonging to 11 spider families and six insect families were collected in the same field of rice. The distribution of Wolbachia in these arthropods was detected by diagnostic PCR amplification of the wsp (Wolbachia outer surface protein gene) and 16S rDNA genes. Nurscia albofasciata Strand (Araneae: Titanoecidae), Propylea japonica Thunberg (Coleoptera: Coccinellidae), Paederus fuscipes Curtis (Coleoptera: Staphylinidae), and Nilaparvata lugens Stal (Homoptera: Delphacidae) were infected with...

Histochemical and ultrastructural evidence of lipid secretion by the silk gland of the sugarcane borer Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae)
Provedor de dados: 82
Autores: Victoriano,Eliane; Pinheiro,Daniela O.; Gregório,Elisa A.
The silk gland in Lepidoptera larvae is responsible for the silk production used for shelter or cocoon construction. The secretion of fibroin and sericin by the different silk gland regions are well established. There are few attempts to detect lipid components in the insect silk secretion, although the presence of such element may contribute to the resistance of the shelter to wet environment. This study characterizes the glandular region and detects the presence of lipid components in the secretion of the silk gland of Diatraea saccharalis(Fabricius). The silk gland was submitted to histochemical procedure for lipid detection or conventionally prepared for ultrastructural analyses. Lipid droplets were histochemically detected in both the apical cytoplasm...

Autores: Margatto,Cleiton; Berno,Vinicius Ortega; Gonçalves,Rodrigo Barbosa; Faria,Luiz Roberto Ribeiro.
Abstract Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry seasons, where climatic variables are regarded to be good predictors of populational patterns. The main goal of this paper is to investigate the seasonality of males of orchid bees in fragments of Seasonal Semideciduous Forest in southern Brazil. Data comprise bait samples from five one-year periods on four forest fragments. The seasonality of species abundance was tested with circular statistics. Results suggest two phenological patterns, one for Eufriesea violacea (Blanchard), Eulaema nigrita...

Ultrastructural detection of lipids in the cephalic salivary glands of Apis mellifera and Scaptotrigona postica (Hymenoptera: Apidae) workers
Provedor de dados: 103
Autores: Poiani,Silvana Beani; Cruz-Landim,Carminda da.
ABSTRACT Secretory cells of the cephalic salivary glands (CSGs) of eusocial bees produce and accumulate lipid-like secretion in the lumens of their alveoli. Correspondingly, secretory cells present typical ultrastructural features of lipid-compound producers. Previous work on bees has revealed inter-specific differences in the chemical composition of secretion, and the production mechanisms and secretory cycle of secretory cells. In this work a comparative analysis of the mechanisms of lipid storage in the CSGs of Apis mellifera (Linnaeus, 1758) and Scaptotrigona postica (Latreille, 1807) workers was carried out. The ultrastructural location of lipids was ascertained using imidazole-osmium (IO), using individuals in different stages of their life cycles....

Autores: Ávila,Crébio José; Parra,José Roberto Postali.
Studies related to the feeding behavior of pest insects provide information that will aid the development of control tactics. Leaf consumption by Diabrotica speciosa adults fed on bean, corn, potato and soybean was determined in the laboratory under free-choice (multiple or double-choice) and no-choice (confinement) conditions. In the multiple-choice tests leaf circles were randomly arranged in a circular pattern (arena) inside Petri dishes. The degree of preference for the hosts was determined under double-choice conditions, where common bean was considered the standard host and the remaining plants (soybean, potato and corn) as test hosts. In all trials, two Diabrotica speciosa couples were released and maintained within the dish for 24 hours; the leaf...

6-phosphofructo-1-kinase (phosphofructokinase; PFK) activity from Rhodnius prolixus, a haematophagous insect which is usually a poor flyer, was measured and compared in two metabolically active tissues - flight muscle and fat body. The activity of this important regulatory glycolytic enzyme was much more pronounced in muscle (15.1 ± 1.4 U/mg) than in fat body extracts (3.6±0.4 U/mg), although the latter presented higher levels of enzyme per protein content, as measured by western-blotting. Muscle extracts are more responsible than fat body to ATP and fructose 6-phosphate, both substrates of PFK. Allosteric regulation exerted by different effectors such as ADP, AMP and fructose 2,6-phosphate presented a singular pattern for each tissue. Optimal pH (8.0-8.5)...

A survey of the fungal microbiota of the digestive tract of Triatoma infestans (Klug) (Hemiptera: Reduviidae) adults was carried out. Insects captured in the field from different provinces in Argentina, as well as individuals reared in artificial colonies, were used for dissection. Axenic cultures of the fungal species were identified and were deposited with mycological collections at La Plata , Argentina. A total of 33 fungal species, with the exception of three that were mycelia sterilia, belonging to 11 genera were identified. Thirty two species belonged to Ascomycota (Eurotiomycetes and Sordariomycetes) and one to Zygomycota (Zygomycetes). The genera with the greatest number of species were Penicillium (15), Aspergillus (5), and Cladosporium (2). Among...

Ultrastructural and quantitative studies of hemocytes in the sugarcane borer, Diatraea saccharalis (Lepidoptera: Pyralidae)
Provedor de dados: 52
Autores: Falleiros,Ângela Maria Ferreira; Bombonato,Maria Terezinha Siqueira; Gregório,Elisa Aparecida.
Six circulating hemocytes cell types from Diatraea saccharalis (Fabricius) (Lepidoptera: Pyralidae) larvae were identified by transmission and scanning electron microscope: prohemocytes (PR), plasmatocytes (PL) granulocytes (GR), spherulocytes (SP), oenocytoids (OE) and vermicytes (VE). The PR was the smallest cell type with a large nucleus, a cytoplasm with few organelles and a homogenous smooth surface. The PL was polymorphic and abundant, with a cytoplasm rich in organelles and a cellular surface with several cytoplasmic projections. The GR was abundant, showing two types of membrane-bounded granules (dense and structutered), glycogen, lipid droplets and a surface with philopodial projections. The SP was a large cell, with a cytoplasm full of...

Latex is an endogenous milky fluid synthesized and accumulated under pressure in a network of laticifer cells. In this study, latices from five plant species were examined for deterrent effect on oviposition of two Coleoptera (Bruchidae) pests. The latex from Euphorbia tirucalli, Calotropis procera and Plumeria rubrae exhibited deterrent activity on oviposition of both Callosobruchus maculatusand Zabrotis subfasciatus beetles. The latex from Cryptostegia grandiflora and Himathantus drasticus were less effective to C. maculatus and Z. subfasciatus oviposition, respectively. Eggs laid on latex-treated seeds were not affected.The emergence and the mean time of development and weight of larvae grown in treated seeds were similar to the controls. The deterrent...

ABSTRACT: The deficient development of fertile seeds of native forest plant species in Brazil limits the reproduction of these plants in various conditions. Among the limiting biotic factors in quality and quantity of the forest seeds, borer insects are quite prominent, before and after their dispersion. This study reports for the first time a host of the buprestid beetle Lius conicus (Gory &amp; Laporte, 1840). The larval development of L. conicus takes place in the seed capsules of Vochysia haenkeana Mart. (Vochysiaceae), a typical tree species in the Brazilian cerrado biome. In two regions of the cerrado in Goiás State, Brazil, almost ripe fruits of V. haenkeana were collected directly from the plants. After natural drying, and fruit and seed processing...
