Resumo: The objective of this work was to evaluate the effect of insecticides on the control of whitefly (Bemisia argentifolii Bellows & Perring, 1994), on golden mosaic virus incidence and on common bean yield. Seed treatment with the insecticides imidachloroprid or thiamethoxam followed by insecticide sprays at weekly internals were used. The experiment was conducted in a randomized complete block design in an irrigated area in Petrolina, PE, Brazil, with five treatments and four replicates. The chemical control decreased significantly the number of eggs, nymphs and adults, and also the percentage of infection by the golden mosaic virus in the bean crop. Grain yields for chemical treatments in the tilled plots ranged from 1,930 to 2,405 kg/ha, while the control yielded 1,490 kg/ha. There were no significant differences for number of pods per plant and for 100-seed weight.

Utilizou-se de tratamento de sementes com imidacloprid ou thiamethoxam, e de pulverizações de inseticidas, em intervalos semanais. O experimento foi realizado no campo, em área irrigada, em Petrolina, PE, em blocos ao acaso, com cinco tratamentos e quatro repetições. Houve redução significativa no número médio de ovos, de ninfas e de adultos da mosca-branca e na porcentagem de infecção pelo vírus-do-mosaico-dourado do feijoeiro. A produtividade nas parcelas tratadas variou de 1.930 a 2.405 kg/ha, enquanto na testemunha foi de 1.490 kg/ha. Não foi observada diferença significativa entre os tratamentos, no número de vagens/planta e peso de 100 sementes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBarbosa, Flávia RabeloSiqueira, Katia Maria Medeiros deSouza, Eduardo Alves deMoreira, Wellington AntonioHaji, Francisca Nemaura PedrosaAlencar, José Adalberto de2002-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6414Pesquisa Agropecuaria Brasileira; v.37, n.6, jun. 2002; 879-883Pesquisa Agropecuária Brasileira; v.37, n.6, jun. 2002; 879-8831678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6414/3471info:eu-repo/semantics/openAccess2014-07-22T17:30:47Zoai:ojs.seer.sct.embrapa.br:article/6414Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-22T17:30:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
