and are successful biological invaders of agroecosystems. Their integrated pest management (IPM) programs involve the release and/or conservation of natural enemies. Among these, is a major Asian parasitoid of and has been introduced as a classical biological control agent of this pest in Europe and North America, while is a key fortuitous parasitoid of in the Mediterranean region. Bioinsecticides represent key alternatives to chemicals for controlling both pests. This study investigated the potential compatibility of both parasitoids with , , garlic essential oil (EO), and spinosad, in comparison to two synthetic insecticides, cyantraniliprole and chlorantraniliprole. The results showed that combining each of the tested insecticides with slightly increased pest mortality compared to the insecticide alone. had a significant additive effect on host mortality when combined with insecticides. and were most compatible with both parasitoid species. Both garlic EO and chlorantraniliprole impaired the survival of immature and showed sublethal toxicity on the reproductive and non-reproductive behaviors of . Spinosad exhibited high acute toxicity on both juvenile and adult parasitoids of both species. Overall, these findings provide useful insights into insecticide selectivity toward two key parasitoids and offer new knowledge on the potential of combining natural enemies and bioinsecticides for optimized IPM.
[物种名称1]和[物种名称2]是农业生态系统中成功的生物入侵者。它们的综合虫害管理（IPM）计划涉及释放和/或保护天敌。其中，[物种名称3]是[害虫名称1]在亚洲的主要寄生蜂，并已作为该害虫的经典生物防治剂引入欧洲和北美，而[物种名称4]是地中海地区[害虫名称2]的关键偶然寄生蜂。生物杀虫剂是控制这两种害虫的化学药剂的关键替代品。本研究调查了这两种寄生蜂与[生物杀虫剂名称1]、[生物杀虫剂名称2]、大蒜精油（EO）和多杀菌素的潜在兼容性，并与两种合成杀虫剂氰虫酰胺和氯虫酰胺进行了比较。结果表明，与单独使用杀虫剂相比，将每种测试杀虫剂与[物种名称3]组合使用时，害虫死亡率略有增加。[物种名称4]与杀虫剂组合时对宿主死亡率有显著的累加效应。[生物杀虫剂名称1]和[生物杀虫剂名称2]与两种寄生蜂物种的兼容性最高。大蒜EO和氯虫酰胺均损害了未成熟[物种名称3]的存活，并对[物种名称4]的生殖和非生殖行为表现出亚致死毒性。多杀菌素对两种物种的幼虫和成虫寄生蜂均表现出高急性毒性。总体而言，这些发现为杀虫剂对两种关键寄生蜂的选择性提供了有用的见解，并为将天敌和生物杀虫剂结合用于优化综合虫害管理的潜力提供了新知识。
