Among the several options for controlling Alabama argillacea (Hübner) and Heliothis virescens (Fabricius) larvae on the cotton crop, as insecticides spraying and biological control, the transgenic Bt-cotton has been inserted as an extremely viable alternative, however it is not known with accuracy as the transgenic plants affect the populations of organisms that correlate with each other in an agroecossistem. In that sense, the knowledge of the possible alterations in the spatial disposition of the pests or beneficial insects it is extremely important, because it can alter the sampling method for those species on the crop, besides its control method. This study was carried out aiming to determine the spatial distribution pattern of A. argillacea and H. virescens eggs on cotton crop, cultivars DeltaOpal® (conventional) and DP90B® (Bt-cotton). The data were collected during the agricultural year 2006/2007 in two different areas of 5,000 m2 each one in Dourados region. In each sampling area, composed for 100 plots of 50m2 each one, 15 evaluations were accomplished through the countings of eggs from these pests in two plants per plot. The aggregation indexes (variance/mean rate, Morisita index, and Exponent k of the Negative Binomial Distribution) and the qui-square test with the adjustment of the found and expected values to the frequencies theoretical distributions (Poisson, Negative Binomial, and Positive Binomial) revealed that in the both cultivars the spatial distribution of egss from those species are distributed in agreement to the aggregated spatial distribution model, being adjusted to the pattern of the negative binomial distribution.
Dentre as opções para o controle de lagartas de Alabama argillacea (Hübner) e Heliothis virescens (Fabricius) na cultura algodoeira tem-se, normalmente, a aplicações de inseticidas e o controle biológico. Nesse contexto, o algodão transgênico Bt tem se inserido como uma alternativa extremamente viável, porém não se sabe, com exatidão, como as plantas transgênicas afetam as populações de organismos que se inter-relacionam em um agroecossistema. Nesse sentido, o conhecimento da possível alteração da forma da disposição espacial de insetos pragas, ou benéficos é extremamente importante, pois esta disposição pode alterar o método de amostragem dessas espécies na cultura, além de sua forma de controle. Este estudo foi conduzido buscando investigar o padrão da distribuição espacial de ovos de A. argillacea e de H. virescens em cultivar DeltaOpal® (convencional) e DP90B® (algodão-Bt). A coleta dos dados ocorreu durante o ano agrícola 2006/2007 em duas áreas de 5.000 m2 localizada na região da Grande Dourados. Em cada área amostral, composta por 100 parcelas de 50m2, foram realizadas 15 avaliações com contagens dos ovos das pragas em análise, em duas plantas por parcela. Os índices de agregação (razão variância/média, índice de Morisita e Expoente k da Distribuição Binomial Negativa) e o teste de qui-quadrado, com o ajuste dos valores encontrados e esperados às distribuições teóricas de freqüência (Poisson, Binomial Negativa e Binomial Positiva), mostraram que em ambas cultivares a distribuição espacial de posturas dessas espécies estão distribuídas de acordo com o modelo de distribuição espacial agregada, ajustando-se ao padrão da distribuição binomial negativa

O Brasil é o segundo maior produtor de soja do mundo, com áreas de cultivo ocupando 3,5% do território nacional. Grande parte da produtividade é oriunda de cultivares transgênicas que expressam a toxina Cry1Ac de Bacillus thuringiensis Berliner, que visam reduzir densidades populacionais dos lepidópteros praga-chave. A cienciometria realizada nos registros do sítio Web of ScienceTM, aponta um número crescente de pesquisas envolvendo toxinas Cry e os noctuóideos, buscando estratégias e soluções para uma melhor gestão dos agroecossistemas. O trabalho foi desenvolvido em cultivo de soja não-Bt e Bt sem a utilização de inseticidas, na safra 2015/2016, na área experimental da Embrapa Cerrados, Planaltina, DF. Foram listadas 13 espécies de noctuóideos associados à cultura da soja, registrando-se pela primeira vez as espécies Elaphria deltoides (Möschler, 1880) e Utetheisa ornatrix (Linnaeus,1758). A baixa incidência de lagartas em campo não atingiu o nível de controle, no entanto o número de lagartas coletadas na soja não-Bt foi 11,5 vezes superior ao encontrado na soja Bt, indicando os efeitos da toxina Cry1Ac sobre os noctuóideos associados à soja. Dessa forma, reforça-se a necessidade de monitoramento das áreas de cultivos de soja, visando a melhor avaliação dos reais acontecimentos em nível de campo. Ao final, aponta-se que o os parasitoides foram beneficiados pelo manejo da área experimental sem a utilização de inseticidas, proporcionando o controle biológico natural com uma taxa de parasitismo superior a 35%.
Brazil is the second largest producer country of soybean in the world, with crop areas occupying 3.5% of the national territory. Most of the productivity comes from transgenic varieties that express the Cry1Ac toxin from Bacillus thuringiensis Berliner, which aim to reduce the population densities of the moth key pests. In the cienciometry carried out by the registries on the Web of ScienceTM, it is pointed out an increase of investigations involving Cry toxins and noctuids, searching strategies and solutions for a better management of the agroecosystems. Our study realized in the 2015/2016 crops in the experimental area of Embrapa Cerrados, Planaltina, DF on non-Bt and Bt soybean cultivation areas without insecticides sprayed reports a total of 13 species of noctuids associated with soybean cultivation, with Elaphria deltoides (Möschler, 1880) and Utetheisa ornatrix (Linnaeus,1758) being registered for the first time. The low incidence of caterpillars in the field did not reach the Control Level, however the number of caterpillars collected in non-Bt soybean was 11.5 times higher than that found in Bt soybean, indicating the effects of the Cry1Ac toxin on the noctuids associated with soybean. Therefore, it is necessary to reinforce monitor soybean crop areas, aiming at the best evaluation of the real events at the field level. It is pointed out that the parasitoids were benefited by the management of the experimental area without the use of insecticides, providing the natural biological control with a parasitism rate up to 35%.

Full textResumo: Embora o Brasil seja o segundo maior produtor de soja [Glycine max (L.) Merrill] do mundo, a produtividade desse grão é afetada diretamente pela incidência de insetos-praga. Dentre as pragas, os lepidópteros Chrysodeixis includens (Walker) e Spodoptera eridania (Stoll) (Noctuidae) têm causado danos expressivos nos últimos anos. As práticas de controle mais empregadas no manejo dessas pragas envolvem a aplicação de inseticidas sintéticos e o uso da tecnologia Bt. No entanto, a movimentação larval dessas espécies pode comprometer essas estratégias, com impactos relevantes sobre o Manejo Integrado de Pragas (MIP) e o Manejo de Resistência de Insetos (MRI). Para a espécie S. eridania, existe um agravante, visto que a mesma apresenta baixa suscetibilidade à toxina Cry1Ac. Nesse sentido, esse estudo teve como objetivo caracterizar a movimentação de diferentes ínstares larvais dessas duas espécies e o possível impacto que esse comportamento tem sobre o MIP e MRI. Assim, foram realizados estudos de movimentação larval na planta e entre plantas em cultivares de soja Bt (TMG 7062 IPRO) e não Bt (TMG 7262 e 92Y83 “Pioneer”) em período reprodutivo sob condições de laboratório, casa de vegetação e campo. Nos estudos de movimentação na planta. Foram avaliadas a distribuição larval em três posições (superior, mediano e basal) das plantas e em diferentes períodos, além da permanência dos insetos sobre as plantas. Os estudos de movimentação larval entre plantas tiveram como objetivo caracteri... (Resumo completo, clicar acesso eletrônico abaixo)
