Resumo: The objective of this work was to develop an experimental protocol to assess the impact of Bt cotton on bionomics and on plant choice for Aphis gossypii colonization. The bionomics of the cottonaphid was assessed in greenhouse with insects reared in individual cages containing Bt cotton plants of the variety DP 404 BG (Bollgard) or its nontransformed isoline DP 4049. Cages with Bt cotton and non-Bt cottonwere used as choosing arena for evaluation of winged adults preference. There was no signifi cant difference for pre-reproduction period (immature phase), reproduction period, longevity, survivorship curve total and daily production of offspring by female, and curve of accumulated production of offspring by the population.There was no preference of colonization for any plant by winged adults, which indicates equivalent rates of colonization of the initial populations. Bt cotton plants do not affect the population dynamics of A. gossypii,and do not increase its potential risk as pest.

A bionomia do pulgão foi avaliada em casa de vegetação com insetos criados em gaiolas individuais com plantas de algodão Bt, da variedade DP 404 BG (Bollgard), ou sua isolinha não transformada DP 4049. Gaiolas contendo vasos com plantas de algodoeiro Bt e não-Bt foram usadas como arena de escolha, para a avaliação de preferência de adultos alados. O período pré-reprodutivo e reprodutivo, a longevidade, a curva de sobrevivência, a produção de prole total e diária por fêmea e a curva acumulada de produção de prole da população não apresentaram diferenças signifi cativas. Não foi observada diferença na escolha de plantas para colonização por indivíduos alados, o que indica taxas equivalentes de colonização nas populações iniciais.O algodoeiro Bt não afeta a dinâmica populacional de A. gossypii e não aumenta seu potencial de risco comopraga.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, FINEPESujii, Edison RyoitiTogni, Pedro Henrique BrunNakasu, Erich Yukio TempelPires, Carmen Silvia SoaresPaula, Débora Pires deFontes, Eliana Maria Gouveia2008-10-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/792Pesquisa Agropecuaria Brasileira; v.43, n.10, out. 2008; 1251-1256Pesquisa Agropecuária Brasileira; v.43, n.10, out. 2008; 1251-12561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/792/5509info:eu-repo/semantics/openAccess2014-07-17T16:57:06Zoai:ojs.seer.sct.embrapa.br:article/792Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T16:57:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
