摘　　要：目的测定JWX-Ⅱ型卫生杀虫剂超低容量喷雾对淡色库蚊、家蝇的杀灭效果。方法以淡色库蚊、家蝇为试验对象,对JWX-Ⅱ型卫生杀虫剂进行室内药效、外环境模拟现场药效、现场药效测定。结果该杀虫剂用水稀释100倍后,室内按1.43ml/m3喷雾,对淡色库蚊、家蝇的KT50分别为4.39和3.79min,24h死亡率均为100%;外环境模拟现场距离喷药点5、10、15、20m按0.5mg.ai/m2喷药,10m内对淡色库蚊、家蝇的1h击倒率和24h死亡率均在95%以上;现场对部队野外驻训的4个宿营地按0.5mg.ai/m2喷药,喷药后1h蚊虫密度下降率平均达95.69%。结论该药剂高效、速效、低毒、无异味,适合超低容量喷雾。Objective To evaluate the killing effects of ultralow-volume spraying of hygienic insecticide JWX-Ⅱ on mosquitoes and flies.Methods Laboratory test,simulated field test,and field test were carried out to evaluate the killing effects of hygienic insecticide JWX-Ⅱ on Culex pipiens pallens and Musca domestica.Results In the laboratory test,the KT50 values of JWX-Ⅱwere 4.39 min and 3.79 min for Cx.pipiens pallens and M.domestica when diluted 100 times with water and sprayed at 1.43 ml/m3;the death rates of both insects were 100% within 24 h.In the simulated field test,JWX-Ⅱ was sprayed at a dose of 0.5 mg·ai/m2 and a distance of 5,10,15,or 20 m;the 1 h knock down rates and 24 h death rates were more than 95% for both insects when JWX-Ⅱ was sprayed at a distance of 10 m.In the field test,JWX-Ⅱ was sprayed at 0.5 mg·ai/m2 in four encampments for field training of troops;the density of mosquitoes decreased on average by 95.69% one hour after spraying.Conclusion Hygienic insecticide JWX-Ⅱ has the advantages of high efficiency,quick acting,low toxicity,and no offensive odor and is suitable for ultralow-volume spraying.
