摘　　要：目的通过了解绵阳市北川县地震后致倦库蚊对常用杀虫剂的敏感性,为防治提供科学的方法。方法按照《全国重要病媒生物抗药性监测(试行)方案》,采用致倦库蚊幼虫浸渍法进行测定。结果北川县致倦库蚊对常用化学杀虫剂敌敌畏、高效氯氰菊酯、溴氰菊酯的LC50值分别是0.530 7、0.045 6和0.022 1mg/L;抗性倍数分别为29、12、17。结论北川县致倦库蚊对主要化学杀虫剂敌敌畏、高效氯氰菊酯和溴氰菊酯均产生不同程度的抗性。抗性调查的结果可为指导北川县病媒蚊虫及其传染病防治以及合理使用卫生杀虫剂提供参考。Objective To investigate the resistance of Culex pipiens pallens to commonly used insecticides. Methods Larva immersion method. Results The LCs0 s of DDVP, beta-cypermethrin and deltamethrin to Culex pipiens pal- lens in Beichuan county were 0. 530 7,0. 045 6,0. 022 1 mg/L respectively, and the resistance ratios were 29,12 and 17. Conclusion In the earthquake area of Beichuan county in Sichuan, Culex pipiens pallens has developed different resistance to DDVP, dehamethrin and beta-cypermethrin. The resistance result can provide guidnce for control vector mosquito and its infectious disease, and provide reference for using insecticides reasonably in Beichuan county.
