目的观察高效氯氟氰菊酯浸泡蚊帐实验室和现场试验防蚊灭蚊效果。方法实验室试验强迫接触法和现场试验。结果高效氯氟氰菊酯实验室试验3组剂量对淡色库蚊击倒率和杀灭率随着剂量的增加而升高,40 mg/m2剂量组灭蚊持效可达90 d以上;现场试验40 mg/m2剂量组在60 d内始终维持在90%以上。结论高效氯氟氰菊酯浸泡蚊帐防蚊灭蚊效果好,现场应用应以40 mg/m2剂量浸泡蚊帐为宜。
Objective To observe the effect of lambda-cyhalothrin in mosquito nets laboratory and field test on mosquito-killing and mosquito-killing. Methods Laboratory test forcing contact method and field test. Results The rates of killing and killing of Culex pipiens pallens in 3 groups were increased with the increase of dose, and the persistence of mosquito in 40 mg / m2 dose group was more than 90 days. Test 40 mg / m2 dose group within 60 d maintained at more than 90%. Conclusion Cyhalothrin infiltration mosquito nets mosquito mosquito good effect, the field application should be 40 mg / m2 dose soak mosquito nets is appropriate.
