Adult attractiveness and oviposition preference of Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) B-biotype in cotton genotypes Scientia Agricola
Boiça Júnior,Arlindo Leal; Campos,Zeneide Ribeiro; Lourenção,André Luiz; Campos,Alcebíades Ribeiro.
The silverleaf whitefly Bemisia tabaci B-biotype is an important pest of cotton; it affects plant vigour, transmits geminivirus and reduces lint quality. In order to evaluate the resistance of cotton genotypes, Gossypium hirsutum (L.), to the whitefly Bemisia tabaci B-biotype, both free-choice and no-choice attractiveness and non-preference for oviposition tests were carried out in a shade house, at room temperature. Low attractiveness to adults of this whitefly was observed for plants of genotypes Fabrika, CNPA Ita 90, Makina, Coodetec 407, and IAC 01-639 CPA 02-24, which may represent a resistance component of these genetic materials to the insect. Genotypes BRS Aroeira, Coodetec 406, Fabrika, and Coodetec 401 presented the non-preference-for-oviposition...

Antibiosis effects of wild bean lines containing arcelin on Bemisia tabaci (Genn.) biotype B (Homoptera: Aleyrodidae) Anais da SEB
Oriani,Maria A. de G.; Lara,Fernando M..
The biology of Bemisia tabaci biotype B (Genn.) on bean (Phaseolus vulgaris L.) genotypes containing arcelin in the seeds was evaluated. Also, biochemical screening of seeds and leaves material of these genotypes were carried out in order to verify if traces of arcelin could be found in its leaves. The tests were conducted under greenhouse conditions, in the dry and wet seasons, with the following genotypes: ARC 3s, ARC 5s (wild genotypes containing arcelin in the seeds); ARC 1, ARC 2, ARC 3, ARC 4 (near isogenic lines containing arcelin in the seeds - EMBRAPA) and Porrillo 70, Bolinha, IAPAR MD 808 (commercial genotypes without arcelin). The wild genotypes, ARC 3s and ARC 5s, showed high levels of antibiosis resistance type, mainly for ARC 5s which...

Antixenosis of bean genotypes to Chrysodeixis includens (Lepidoptera: Noctuidae) PAB
Morando,Rafaela; Baldin,Edson Luiz Lopes; Cruz,Patrícia Leite; Lourenção,André Luiz; Chiorato,Alisson Fernando.
The objective of this work was to evaluate bean genotypes for resistance to soybean looper (Chrysodeixis includens). Initially, free-choice tests were carried out with 59 genotypes, divided into three groups according to leaf color intensity (dark green, light green, and medium green), in order to evaluate oviposition preference. Subsequently, 12 genotypes with high potential for resistance were selected, as well as two susceptible commercial standards. With these genotypes, new tests were performed for oviposition in a greenhouse, besides tests for attractiveness and consumption under laboratory conditions (26±2ºC, 65±10% RH, and 14 h light: 10 h dark photophase). In the no-choice test with adults, in the greenhouse, the 'IAC Jabola', Arcelina 1, 'IAC...

Assesing Bemisia tabaci (Genn.) biotype B resistance in soybean genotypes: Antixenosis and antibiosis Chilean J. Agric. Res.
Gonçalves Franco da Silva,José Paulo; Lopes Baldin,Edson Luiz; Santana de Souza,Efrain; Lourenção,André Luiz.
Since it was first reported in Brazil in the 1990s, the B biotype of silverleaf whitefly (Bemisia tabaci Genn., Hemiptera: Aleyrodidae) has been recognized as an important pest in soybeans (Glycine max L.), reducing the productivity of this legume species in some areas of the country. As an alternative to chemical control, the use of resistant genotypes represents an important tool for integrated pest management (IPM). This study evaluated the performance of 10 soybean genotypes prior to whitefly infestation, by testing attractiveness and preference for oviposition in the greenhouse and antibiosis in the laboratory. In a multiple-choice test, 'IAC-17' was the least attractive to insects. In a no-choice test, 'IAC-17' was the least attractive for egg...

Silva,Anderson Gonçalves da; Boiça Junior,Arlindo Leal; Farias,Paulo Roberto da Silva; Souza,Bruno Henrique Sardinha de; Rodrigues,Nara Elisa Lobato; Carbonell,Sérgio Augusto Morais.
ABSTRACT: Whitefly Bemisia tabaci (Gennadius) biotype B is the major pest of common bean (Phaseolus vulgaris L.) in Brazil and other countries. Host plant resistance is one of the cornerstones of Integrated Pest Management (IPM), and assessment of cultivars for insect resistance is fundamental to provide farmers options for pest control. This study evaluated common bean resistance to whitefly in the winter and rainy seasons in Jaboticabal, Brazil, and correlated the infestation with climatic factors. The plant part and development period of common bean that are more susceptible to whitefly infestation were also examined for potential use in IPM. Field experiments were carried out using 18 and 19 commercial cultivars in the winter and rainy seasons,...

Determinação do período de avaliação de não-preferência de sorgo ao pulgão-verde, Schizaphis graminum (Rond.) (Homoptera: Aphididae) Anais da SEB
Cruz,Ivan; Vendramim,José D.; Oliveira,Antônio C..
To determine the evaluation period of preference of the greenbug, Schizaphis graminum (Rond.) to sorghum (Sorghum bicolor) genotypes, a study was conducted at the Embrapa/National Corn and Sorghum Research Center, Sete Lagoas, MG, using different sources of resistance. Cultivars were randomized within pots and 11-d after planting five apterous adult greenbugs/plant were released in the center of the pot. Evaluations based on the number of insects in each genotype, after 24, 48, 72 and 96 hours of the insects release indicated that 72 hours after infestation was the ideal period to evaluate the non-preference of S. graminum to sorghum.

Effect of arcelin protein on the biology of Zabrotes subfasciatus (Boheman 1833), in dry beans PAB
Barbosa,Flávia Rabelo; Yokoyama,Massaru; Pereira,Pedro Antônio Arraes; Zimmermann,Francisco José Pfeilsticker.
Arcelin is a seed protein found in wild beans (Phaseolus vulgaris) which gives resistance to Mexican bean weevil, Zabrotes subfasciatus (Boheman 1833) (Coleoptera: Bruchidae). Studies were carried out with the objective of estimating the effect of four alleles of protein arcelin (Arc1, Arc2, Arc3 and Arc4) on the biology of Z. subfasciatus. The experiment was carried out in laboratory at Embrapa-Centro Nacional de Pesquisa de Arroz e Feijão, in Santo Antônio de Goiás, GO, Brazil, under non controlled conditions. The highest levels of antibiosis to Z. subfasciatus were observed in Arc1, with reduction in the number of eggs, number of emerged adults, adults longevity. In the line Arc2 only reduction in the number of emerged adults was observed. The lines...

Effect of gossypol on survival and reproduction of the zoophytophagous stinkbug Podisus nigrispinus (Dallas) Rev. Bras. entomol.
Evangelista Junior,Walter S.; Santos,Roberta L.; Torres,Jorge B.; Zanuncio,José C..
Effect of gossypol on survival and reproduction of the zoophytophagous stinkbug Podisus nigrispinus (Dallas). Gossypol is a sesquiterpene aldehyde found in cotton plants conferring resistance against herbivory. Although the effect of this sesquiterpenoid on insect pests of cotton is known, the interaction of this compound with zoophytophagous predators such as Podisus nigrispinus (Dallas) (Hemiptera, Pentatomidae) has not been studied so far. Thus, the objective of this study was to evaluate the effect of the purified gossypol on nymphs and adults of P. nigrispinus. Nymphs and adults of this predator were fed on Tenebrio molitor pupae and supplemented with solutions of gossypol at concentrations of 0.00, 0.05, 0.10, and 0.20% (w/v) during the nymphal and...

Evaluation of forage grass resistance to Mahanarva fimbriolata (Stål) Bragantia
Grisoto,Eliane; Vendramim,José Djair; Lourenção,André Luiz; Usberti,José Alfredo; Olinda,Ricardo Alves de.
ABSTRACT The aim of this study was to select forage grasses with potential resistance to Mahanarva fimbriolata by assessing effects on insect. No-choice assays were conducted with 12 genotypes and laboratory-reared insects. The following parameters were assessed: mortality and duration of the nymphal stage; adult weight and longevity; pre-oviposition period; number of eggs/female; viability and duration of the embryonic period. As main result it was verified that the mortality of nymphs reared on Panicum maximum cv. Paredão is almost complete and that this forage grass may be characterized as resistant to this insect by antibiosis. Further, the grasses can be divided into three groups following a cluster analysis: P. maximum cv. Aries, Setaria sphacelata...

Infestation by Enneothrips flavens Moulton and yield of peanut cultivars Scientia Agricola
Moraes,Andrea Rocha Almeida de; Lourenção,André Luiz; Godoy,Ignácio José de; Teixeira,Gustavo de Carvalho.
Because of damages caused, general occurrence in crops, and high population levels, the most important peanut pest in Brazil is the thrips Enneothrips flavens Moulton (Thysanoptera: Thripidae). A field experiment was carried out during the 2001/2002 growing season, in Campinas and Pindorama, State of São Paulo, Brazil, to evaluate the influence of E. flavens on yield of six peanut cultivars. Treatments comprised three cultivars of the upright type and three of the runner type, with and without chemical control of the insect. Thrips infestation was evaluated by insect countings on young leaflets. Yield and yield reduction percentage due to the lack of thrips control were estimated. The lack of insect control resulted in yield reductions varying from 19.5 to...

Lourenção,André Luiz; Braga,Nelson Raimundo; Miranda,Manoel Albino Coelho de; Reco,Paulo César; Valle,Giuliana Etore do; Pereira,José Carlos Vila Nova Alves.
The use of soybean cultivars resistant to insects and diseases reduces the application of pesticides, decreasing production costs and promoting a sustainable agriculture. The damage of stink bugs and defoliators and the severity of powdery mildew (Microsphaera diffusa) in soybean of three maturity groups were evaluated under field conditions, at Tarumã and Ribeirão Preto, State of São Paulo, Brazil. Three experiments, one for each group, were carried out in the 1999/2000 and 2000/2001 growing seasons. In 1999/2000, the disease occurred in Tarumã; in that year, infestation of chrysomelids (Cerotoma sp. and Colaspis sp.) was observed in Ribeirão Preto. Low infestations of stink bugs occurred in both years and locations, but in Tarumã, at the stage of plant...

Interaction of Anthonomus grandis and cotton genotypes: biological and behavioral responses. Repositório Alice
SILVA, J. B.; SILVA-TORRES, C. S. A.; MORAES, M. C. B.; TORRES, J. B.; LAUMANN, R. A.; BORGES, M..
The boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae), is a key pest of cotton, Gossypium hirsutum L. (Malvaceae). Knowledge about boll weevil feeding and oviposition behavior and its response to plant volatiles can underpin our understanding of host plant resistance, and contribute to improved monitoring and mass capture of this pest. Boll weevil oviposition preference and immature development in four cotton genotypes (CNPA TB90, TB85, TB15, and BRS Rubi) were investigated in the laboratory and greenhouse. Volatile organic compounds (VOCs) produced by TB90 and Rubi genotypes were obtained from herbivore-damaged and undamaged control plants at two phenological stages ? vegetative (prior to squaring) and reproductive (during squaring) ?...

Lara,Fernando M.; Tanzini,Marcel R..
To determine the resistance of rubber tree clones (Hevea brasiliensis) to Leptopharsa heveae Drake and Poor (Heteroptera: Tingidae) a trial was held in Itiquira, MT, in 1994/95 by comparing the following clones: AVROS 2037, Fx 4037, GT 1, HARBEL, IAC 207, IAN 4493, IAN 717, IAN 873, RO 38, and RO 46. Free choice and no choice trials involving preference for oviposition and feeding were carried out under field and laboratory conditions. The symptoms caused by the insects, number of excrements, number of eggs/female/leaflet, mortality rate, and number of insects/leaflet were scored. The results showed that clones Fx 4037, RO 38 and RO 46 were resistant by nonpreference for feeding and oviposition, whereas GT and IAN 873 were the most susceptible.

Lourenção,André L; Reco,Paulo C; Braga,Nelson R; Valle,Giuliana E do; Pinheiro,José B.
Three soybean experiments, one for each maturation group (early, semi-early, and medium), were installed in the field in Assis, State of São Paulo, during the 2003/2004 growing season to evaluate damage caused by Anticarsia gemmatalis (Hubn.) and by the soybean stink bug complex, Euschistus heros (F.), Piezodorus guildinii (West.), and Nezara viridula (L.). The experiments were installed again in 2004/2005, with the exception of the early cycle group. Defoliation caused by A. gemmatalis was evaluated by the percentage estimate of leaf area cut in the first year only, due to low caterpillar infestations in 2004/2005. All three stink bug species were present in both growing seasons. In 2003/2004, E. heros was predominant over the other two; in the following...
