摘　　要：为明确氯虫苯甲酰胺、氰氟虫腙和阿维菌素等3种杀虫剂对蜘蛛的选择毒性,指导合理使用农药、协调化学防治与生物防治,本文模拟稻田施药时稻株中上部药膜、基部液层而设计的"管壁药膜底部液层"法测定了以上3种杀虫剂对拟环纹豹蛛和食虫沟瘤蛛两种蜘蛛的毒力,并通过安全系数评估其对供试蜘蛛的安全性。结果表明:氯虫苯甲酰胺对拟环纹豹蛛毒力最低,氰氟虫腙对食虫沟瘤蛛毒力最低,而阿维菌素对食虫沟瘤蛛和拟环纹豹蛛毒力最高;3种杀虫剂对拟环纹豹蛛和食虫沟瘤蛛的安全系数高低顺序为:氯虫苯甲酰胺>氰氟虫腙>阿维菌素。因此,氯虫苯甲酰胺和氰氟虫腙是一种良好的新型杀虫剂,既能有效防治害虫又能减小对自然天敌的杀伤作用,达到保护农作物的目的。For expliciting the selective toxicity of chlorantraniliprole,metaflumizone and avermectins to the spiders,to guide the rational use of pesticides and coordinate chemical control and biological control,this paper determinated the three kinds of pesticide toxicity on the two kinds of spiders. The results showed that the actual toxicity of chlorantraniliprole on spiders,Pardosa pseudaannulata and Ummeliata insecticeps,was the lowest,and avermectins had the most high toxicity. Concerning with the practical dosages in rice fields the safeties of three insecticides to Pardosa pseudaannulata and Ummeliata insecticeps was evaluated as follows：chloratraniliprole metaflumizone avermctins.
