The pupal parasitoid (Hymenoptera: Diapriidae) has been evaluated as a biological agent of . Integrated pest management strategies mostly rely on combined application of multiple insecticides and natural enemies. This study assessed the toxicity of eight common insecticides against in fruit orchards and the effects of semilethal and sublethal doses on . The eight insecticides had higher toxicities to larvae with lower LC values than those for adults. Adults and larvae showed high susceptibility to emamectin benzoate, spinetoram, lambda-cyhalothrin, abamectin, and sophocarpidine. The median lethal doses (LC) of lambda-cyhalothrin and imidacloprid to adults were 60.41 mg/L and 100.58 mg/L, higher than the toxicities of the other six insecticides. Applying chlorantraniliprole, emamectin benzoate, sophocarpidine, abamectin, azadirachtin, and spinetoram resulted in low toxicity to pupae. However, the exposure of pupae or larvae to these insecticides at semilethal and sublethal doses decreased the parasitism or eclosion rate of . These results improve our understanding of the effects of insecticide residues on development and provide a basis for the combined use of chemical and biological options for managing .
蛹寄生蜂（膜翅目：姬小蜂科）已被评估为一种生物防治剂。综合害虫管理策略大多依赖于多种杀虫剂和天敌的联合应用。本研究评估了八种常见杀虫剂对果园中[害虫名称未给出]的毒性以及半致死剂量和亚致死剂量对[害虫名称未给出]的影响。这八种杀虫剂对[害虫名称未给出]幼虫的毒性更高，其LC值低于成虫。成虫和幼虫对甲氨基阿维菌素苯甲酸盐、多杀霉素、高效氯氟氰菊酯、阿维菌素和苦皮藤素表现出高敏感性。高效氯氟氰菊酯和吡虫啉对[害虫名称未给出]成虫的半数致死剂量（LC）分别为60.41毫克/升和100.58毫克/升，高于其他六种杀虫剂的毒性。施用氯虫苯甲酰胺、甲氨基阿维菌素苯甲酸盐、苦皮藤素、阿维菌素、印楝素和多杀霉素对[害虫名称未给出]蛹的毒性较低。然而，将[害虫名称未给出]蛹或幼虫暴露于这些半致死剂量和亚致死剂量的杀虫剂会降低[害虫名称未给出]的寄生率或羽化率。这些结果增进了我们对杀虫剂残留对[害虫名称未给出]发育影响的理解，并为化学和生物防治方法联合用于防治[害虫名称未给出]提供了依据。
