Resumo: | Trichogramma pretiosum Riley, 1879 is among the most widely used natural enemies to the control of pests in Brazil, thus its preservation on the agroecossystems through selectivity pesticids is fundamental. The selectivity of lambda-cyhalothrin, in two formulations, 50 CS and 250 CS, to T. pretiosum was evaluated the maternal generation and F1 offspring. Eggs of Anagasta kuehniella (Zeller), were given immediately (1 hours), 24 and 48 hours after immersion in the chemical solutions, and eggs treated 0-24, 72-96 and 168-192 hours after parasitism. Lambda-cyhalothrin on the formulation 50 CS and 250 CS, was harmful to T. pretiosum when applied before the contact of the females with the host eggs. The formulation 250 CS was more harmful than the formulation 50 CS, affecting the parasitism capacity, longevity of the females, and survival of the F1 offspring, when applied before and after parasitism. The reduction of the parasitism capacity on eggs of A. kuehniella before immersion in the chemical solutions was 27.39% and 53.12% to the formulation 50 CSA and 250 CS, respectively. |

Neste artigo, avaliou-se a seletividade do lambdacialotrina em duas formulações: 50 CS e 250 CS, para T. pretiosum nas gerações maternal e F1. Foram oferecidos às fêmeas do parasitóide ovos de Anagasta kuehniella (Zeller) imediatamente (1 hora), 24 e 48 horas após a sua imersão nas caldas químicas, bem como ovos parasitados da traça submetidos às soluções inseticidas após 0-24, 72-96 e 168-192 horas do parasitismo, tendo a imersão em água destilada como testemunha. Lambdacialotrina nas formulações 50 CS e 250 CS apresentou-se prejudicial a T. pretiosum quando aplicado antes do contato das fêmeas com o ovo hospedeiro. A formulação 250 CS mostrou efeitos mais prejudiciais ao parasitóide do que a 50 CS, afetando, principalmente, a capacidade de parasitismo e a longevidade das fêmeas bem como a sobrevivência da prole da geração F1, quando aplicada antes e após o parasitismo, diminuindo a porcentagem de emergência dos adultos. Em ovos de A. kuehniella previamente tratados, a redução na capacidade de parasitismo foi de 27,39% e 53,12% para as formulações 50 CS e 250 CS, respectivamente.Universidade Estadual de Maringá2008-04-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/185210.4025/actasciagron.v27i2.1852Acta Scientiarum.
