Laboratory-reared predators, the insidious flower bug, Orius insidiosus (Say), and big-eyed bug Geocoris punctipes (Say), were exposed to 10 insecticides, including three newer insecticides with novel modes of action, using a residual insecticide bioassay. These species are important predators of several economic pests of cotton. Insecticides tested were: azinphos-methyl, imidacloprid, spinosad, tebufenozide, fipronil, endosulfan, chlorfenapyr, cyfluthrin, profenofos, and malathion. There was considerable variation in response between both species tested to the insecticides. Tebufenozide and cyfluthrin were significantly less toxic to male O. insidiosus than malathion. Tebufenozide was also significantly less toxic to female O. insidiosus than malathion. Imidacloprid, tebufenozide, and spinosad were significantly less toxic to male G. punctipes than chlorfenapyr, endosulfan, and fipronil. Spinosad, tebufenozide, and azinphos-methyl were significantly less toxic to female G. punctipes than fipronil and endosulfan. Fecundity of O. insidiosus was significantly greater in the spinosad treatment compared with other treatments including the control. Consumption of bollworm, Helicoverpa zea (Boddie), eggs by O. insidiosus was significantly lower in the fipronil, profenofos, and cyfluthrin treatments compared with other treatments including the control. Consumption of H. zea eggs by G. punctipes was significantly lower in the malathion, profenofos, endosulfan, fipronil, azinphos-methyl, and imidacloprid treatments compared with the control. Egg consumption by G. punctipes was not significantly different in the tebufenozide treatment compared with the control. The lower toxicity of spinosad to G. punctipes is consistent with other reports. Based on these results, the following insecticides are not compatible with integrated pest management of cotton pests: malathion, endosulfan, profenofos, fipronil, and cyfluthrin; while imidacloprid, tebufenozide, azinphos-methyl, and spinosad should provide pest control while sparing beneficial species.
在残留杀虫剂生物测定中，将实验室饲养的捕食性昆虫——阴险小花蝽（Orius insidiosus (Say)）和大眼蝽（Geocoris punctipes (Say)）暴露于10种杀虫剂中，其中包括3种具有新型作用模式的新型杀虫剂。这些物种是棉花几种经济害虫的重要捕食者。所测试的杀虫剂有：谷硫磷、吡虫啉、多杀菌素、虫酰肼、氟虫腈、硫丹、氯虫苯甲酰胺、氟氯氰菊酯、丙溴磷和马拉硫磷。两种受试物种对杀虫剂的反应存在相当大的差异。虫酰肼和氟氯氰菊酯对雄性阴险小花蝽的毒性明显低于马拉硫磷。虫酰肼对雌性阴险小花蝽的毒性也明显低于马拉硫磷。吡虫啉、虫酰肼和多杀菌素对雄性大眼蝽的毒性明显低于氯虫苯甲酰胺、硫丹和氟虫腈。多杀菌素、虫酰肼和谷硫磷对雌性大眼蝽的毒性明显低于氟虫腈和硫丹。与包括对照在内的其他处理相比，多杀菌素处理下阴险小花蝽的繁殖力明显更高。与包括对照在内的其他处理相比，在氟虫腈、丙溴磷和氟氯氰菊酯处理下，阴险小花蝽对棉铃虫（Helicoverpa zea (Boddie)）卵的消耗量明显更低。与对照相比，在马拉硫磷、丙溴磷、硫丹、氟虫腈、谷硫磷和吡虫啉处理下，大眼蝽对棉铃虫卵的消耗量明显更低。与对照相比，虫酰肼处理下大眼蝽的卵消耗量没有显著差异。多杀菌素对大眼蝽较低的毒性与其他报告一致。基于这些结果，以下杀虫剂与棉花害虫的综合虫害管理不兼容：马拉硫磷、硫丹、丙溴磷、氟虫腈和氟氯氰菊酯；而吡虫啉、虫酰肼、谷硫磷和多杀菌素在控制害虫的同时应能保护有益物种。
