摘　　要：目的测定JWX-Ⅰ型卫生杀虫乳油对淡色库蚊、家蝇的杀灭效果。方法以淡色库蚊、家蝇为试验对象,对JWX-Ⅰ型卫生杀虫乳油进行室内药效、模拟现场药效、现场药效及贮存稳定性药效试验测定。结果该杀虫剂用水稀释100倍后,室内按1.43 ml/m3喷雾,对淡色库蚊、家蝇的KT50分别为5.15和3.33min,24 h死亡率均为100%;模拟现场按1.5 ml/m3喷雾,对淡色库蚊、家蝇的1 h击倒率和24 h死亡率均为100%;现场对部队野外驻训的3个宿营地按1.8 mg ai/m2喷雾,喷药后1 h蚊虫密度下降率平均达95.45%;贮存稳定性试验相当于常温下存放2年,对淡色库蚊、家蝇的杀灭率仍达90%以上。结论该药剂高效、速效、贮存稳定性好,适合部队野外驻训使用。Objective To evaluate the control effect of emulsifiable concentrate of JWX- I against mosquitoes and flies. Methods Bioassay, simulated field test, field test and stability test. Results The KTsos of JWX- I were 5.15 and 3.33 min against Culex pipiens paUens and Musca domestica when diluted 100 times with water at the spra- ying dose of 1.43 ml/m3. The mortality rates of 24 h and knockdown rates of 1 h in lab bioassay and simulated field test were 100% to both insects. In the army encampments, the application of 1.8 mg ai/m2 JWX-I controlled 95.45% of mosquitoes. Stored at room temperature for two years, JWX- I still had good control effect against Culex pipiens pallens and Musca domestica. Conclusion JWX-I is a formulation of high effect, quick-acting and good stability, suit- able for army use.
