When Spodoptera litura (Fabricius) larvae were treated with the insecticides deltamethrin, endosulfan, malathion, and carbaryl at dosages causing 30% mortality (LD30), female moths reared from survivors showed similar patterns in the frequency of calling behavior. However, females reared from larvae dosed with deltamethrin had significantly higher titers of sex pheromone than those treated with endosulfan, malathion, or carbaryl, or control individuals. The ratio of the sex pheromone blend, Z9,E12-14:OAc to Z9,E11-14:OAc in females from the deltamethrin treatment group differed significantly from that of female moths in other treatments. In a wind-tunnel bioassay, males reared from larvae treated with deltamethrin, malathion, or carbaryl were less likely to display behaviors resulting in the location of a sex pheromone source than males reared from larvae treated with endosulfan or a solvent control (acetone). Mating success was significantly decreased in pairs containing either males or females reared from larvae that survived treatment with deltamethrin.
用溴氰菊酯、硫丹、马拉硫磷和西维因等杀虫剂以导致30%死亡率（LD30）的剂量处理斜纹夜蛾（Spodoptera litura，Fabricius）幼虫后，由存活幼虫饲养的雌蛾在求偶行为频率上表现出相似模式。然而，由用溴氰菊酯处理过的幼虫饲养的雌蛾，其性信息素滴度显著高于用硫丹、马拉硫磷或西维因处理过的雌蛾，也高于对照个体。溴氰菊酯处理组雌蛾的性信息素混合物Z9,E12 - 14:OAc与Z9,E11 - 14:OAc的比例与其他处理的雌蛾有显著差异。在风洞生物测定中，由用溴氰菊酯、马拉硫磷或西维因处理过的幼虫饲养的雄蛾，与由用硫丹或溶剂对照（丙酮）处理过的幼虫饲养的雄蛾相比，表现出导致定位性信息素源行为的可能性较小。在用溴氰菊酯处理后存活的幼虫饲养的雄蛾或雌蛾组成的配对中，交配成功率显著降低。
