Resumo: The objective of this work was to identify parasitoids of Diamondback Moth in the Federal District. Larvae of the insect were collected in areas treated with insecticides or in untreated areas. Four species of parasitoids were identified: Apanteles sp. (Braconidae), Oomyzus sokolowiskii (Kurdjumov) (Eulophidae), Diadegma sp. (Ichneumonidae) and Actia sp. (Tachnidae). The total rate of parasitism ranged from 5% to 94% in fields untreated with insecticides, while they ranged between 11% to 87% in treated ones. Most Diamondback Moth larvae were found on cabbage head and on the underside of outer cabbage leaves. The larvae distribution could allow them to escape insecticide residues and so also allow parasitoid survival.

Foram identificados quatro parasitóides: Apanteles sp. (Braconidae), Oomyzus sokolowiskii (Kurdjumov) (Eulophidae), Diadegma sp. (Ichneumonidae) e Actia sp. (Tachinidae). O nível de parasitismo nas áreas não tratadas com inseticidas variou de 5% a 94%, enquanto em áreas tratadas variou de 11% a 87%. A maior parte das larvas de traça-das-crucíferas foram encontradas nas cabeças de repolho ou na parte inferior das folhas da saia das plantas. Esta distribuição de larvas sobre as plantas deve permitir que estas escapem do contato com o inseticida, e, conseqüentemente, os parasitóides podem sobreviver nas plantas tratadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBranco, Marina CasteloMedeiros, Maria Alice2001-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6100Pesquisa Agropecuaria Brasileira; v.36, n.1, jan. 2001; 7-13Pesquisa Agropecuária Brasileira; v.36, n.1, jan. 2001; 7-131678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6100/3167info:eu-repo/semantics/openAccess2014-09-16T17:52:24Zoai:ojs.seer.sct.embrapa.br:article/6100Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-16T17:52:24Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
