Resumo: | Bioassays to evaluate the selectivity of pesticides to beneficial organisms are important tools to discriminate products compatible with biological pest control programs. This study aimed to evaluate the effects of the main insecticides used in the soybean crop on the egg parasitoid Ooencyrtus submetallicus (Hymenoptera: Encyrtidae). The tested treatments (active ingredients) were: methomyl, lambda-cyhalothrin + thiamethoxam, beta-cyfluthrin + imidacloprid, novaluron and teflubenzuron, in the highest doses indicated by the manufacturer for the soybean crop, and a control treatment (water). The evaluations enabled to calculate the mortality and parasitism capacity of adults exposed to the pesticides, in addition to the sex ratio of their descendants. Methomyl and lambda-cyhalothrin + thiamethoxam were classified as Class 4 (harmful), beta-cyfluthrin + imidacloprid as Class 3 (moderately harmful), and novaluron and teflubenzuron as Class 1 (harmless). The products classified as Class 3 and Class 4 should, as much as possible, be replaced by insecticides selective to O. submetallicus.

Objetivou-se avaliar os efeitos dos principais inseticidas utilizados na cultura da soja sobre o parasitoide de ovos Ooencyrtus submetallicus (Hymenoptera: Encyrtidae). Os tratamentos (ingredientes ativos) testados foram: metomil, lambda-cialotrina + tiametoxam, beta-ciflutrina + imidacloprid, novaluron e teflubenzuron, nas maiores dosagens indicadas pelo fabricante para a cultura da soja, e um tratamento testemunha (água). As avaliações permitiram calcular a mortalidade e capacidade de parasitismo de adultos expostos aos pesticidas, além da razão sexual dos seus descendentes. Metomil e lambda-cialotrina + tiametoxam foram classificados como Classe 4 (prejudicial), beta-ciflutrina + imidacloprid como Classe 3 (moderadamente prejudicial) e novaluron e teflubenzuron como Classe 1 (inócuo). Os produtos classificados como Classe 3 e Classe 4 devem, na medida do possível, ser substituídos por inseticidas seletivos a O. submetallicus.
