摘　　要：为保护稻田天敌及合理使用农药提供依据 ,采用浸渍法测定了 1 8种常用杀虫剂对拟水狼蛛的毒力 .结果表明 ,溴氰菊脂、顺式氰戊菊脂、氰戊菊酯、毒杀芬、克百威、甲胺膦对拟水狼蛛高毒 ;异丙威、速灭威、乐果、水胺硫磷、害扑威、杀螟硫磷、乙酰甲胺磷、马拉硫磷、杀虫脒对拟水狼蛛具中等毒性 ;灭幼脲 (苏脲 1号 )、杀虫双对拟水狼蛛毒性小 ;噻嗪酮对拟水狼蛛微毒。杀虫剂不同的加工剂型。The toxicities of eighteen insecticides to Pirata subpiraticus were determined by using immersion method .The results showed that different insecticides had different toxicities to Pirata subpiraticus. These insecticides such as deltamethrin,esfenvalerate fenvalerate,camphechlor,carbofuran,methamidophos had high toxicity;isoprocarb,MTMC,dimethoate,isocarbophos,hopcide,fenitrothion,acephate,malathion,chlordimeform had moderate toxicity;suniao one,Shachongshuang had low toxicity;buprofezin had slight toxicity.The results also showed that toxicity varied in different formulations of insecticides.
