摘　　要：目的筛选几种油基拟除虫菊酯复配气雾剂,在实验室观察其对淡色库蚊、家蝇和德国小蠊的杀灭效果。方法根据GB/T13917.2-2009,用圆筒法测定气雾杀虫剂对3种昆虫的半数击倒时间(KT50),根据GB/T13917.10-2009,测试模拟现场实验效果。结果对淡色库蚊的杀灭实验中,1号和3号配方的KT50均<1min,其他2种配方均<2min;对家蝇的杀灭实验中,3号配方的击倒时间最短,为0.90min,其他3种配方均<2min;对德国小蠊的杀灭实验中,KT50值均<1min;3种试虫的24h死亡率均为100%。模拟现场实验中,4种配方对3种试虫的1h击倒率和24h死亡率均为100%。结论 4种复配杀虫剂配方均达到了快速杀灭蚊、蝇和蜚蠊的效果,可以进入下一步实验。Objective To identify efficacy of pyrethroid aerosol insecticides in killing Culex pipiens pallens,Musca domestica and Blattella germanica.Methods KT50 is one of four kinds of aerosol insecticides on three types of insects were tested according to GB/T 13917.2-2009 in hermetic round canister.Killing efficacy in simulated fields was tested according to GB/T 13917.10-2009.Results The KT50 values of four kinds of aerosol insecticides were less than 2 minutes for Cx.pipiens pallens and M.domestica,and less than 1 minute for B.germanica.The 24 h-mortality of insects used in the hermetic round canister was 100%.The one-hour killing efficacy of the four aerosol insecticides in simulated fields for Cx.pipiens pallens,M.domestica and B.germanica was 100%.Conclusion The four aerosol insecticides all showed fast killing effects for Cx.pipiens pallens,M.domestica and B.germanica.
