摘　　要：杀虫剂亚致死剂量对昆虫生理和行为的影响日益受到人们的关注。亚致死剂量杀虫剂影响雄虫嗅觉感受能力,使其不能准确识别性信息素信号,导致对信号的错误整合;对雌虫则影响性信息素各组分的滴度、比例及求偶和交配行为。短期作用可降低两性间的交配率及下一代种群发生量,长期作用则可能使性信息素通讯系统发生漂移。作者综述了菊酯和有机磷两类杀虫剂在这方面的研究进展,并对一些值得深入研究的问题进行了讨论。Effects of sublethal doses of insecticides on physiology and behavior of insects draw more and more attentions in recent years. Treatment with sublethal doses of insecticides not only disturb male＇s sensory accuracy for sex pheromone, leading to a wrong integration of and abnormal behavioral response to the exotic signals, but also influence the biosynthesis of sex pheromone by females, leading to changed amounts or ratios among pheromone components and anural calling behavior. These effects on both male and female may decrease the mating rate of female and consequently decrease its population of next generation. Sustained pressure of sublethal dose insecticide year by year may even induce the drift of sex pheromone communication system of insect. Emphasized on pyrethroids and organophosphorus insecticides, the effects of sublethal dose on the sex pheromone communication system and its possible mechanism are reviewed, and several key points for further studies in the area are discussed.
