Resumo: A field experiment was conducted to evaluate seasonal effect of insecticides on predators and parasitoids of soybean insect pests. A randomized block design was used, with three replications, and the experiment was set up in the experimental station of the Embrapa-Centro Nacional de Pesquisa de Soja, located at Londrina, PR, Brazil. Treatments consisted of insecticide application to control the velvetbean caterpillar (1/21/1993) or the stink bug complex (3/4/1993). Insect population was sampled through the shock technique, consisting of an application of a broad spectrum insecticide over the plants to be sampled, being the insects collected on cloths placed on the ground, and transferred to the laboratory to be identified and counted. Statistical analysis revealed no differences on the populations of species of predators, diptera or himenoptera as a group. No effects of pest resurgence or secondary pest outbreaks were also observed.

Os tratamentos consistiram de aplicações de inseticidas para o controle da lagarta-da-soja (pulverizados em 21/1/93) e percevejos (4/3/93). A técnica empregada para levantamento da população de insetos foi a do método do choque, que consiste na aplicação de um inseticida de alto impacto sobre a comunidade de insetos presente nas plantas, sua coleta sobre panos estendidos no solo, e sua posterior identificação e contagem em laboratório. A análise da variância revelou não haver diferenças significativas entre as populações de predadores, himenópteros e dípteros encontrados, nos diferentes tratamentos estudados. Também não foram verificados os fenômenos de ressurgência de pragas ou o aparecimento de elevadas populações de pragas secundárias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCorso, Ivan CarlosGazzoni, Décio LuizNery, Manoel Eugenio1999-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5399Pesquisa Agropecuaria Brasileira; v.34, n.9, set. 1999; 1529-1538Pesquisa Agropecuária Brasileira; v.34, n.9, set. 1999; 1529-15381678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5399/2591info:eu-repo/semantics/openAccess2010-07-08T18:23:29Zoai:ojs.seer.sct.embrapa.br:article/5399Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-08T18:23:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
