摘要:

目的 了解咸阳市淡色库蚊对5种杀虫剂的抗药性现状,为制定防制对策提供科学依据。方法 采用区分剂量法测定淡色库蚊幼虫对5种杀虫剂的24 h死亡率。结果 咸阳市淡色库蚊对DDT、敌敌畏、氯菊酯和溴氰菊酯的抗性均达到高抗以上,24 h死亡率分别为23.45%、14.02%、28.77%和25.00%;对氯氰菊酯的抗性达到中抗以上,24 h死亡率为58.63%。结论 咸阳市淡色库蚊对5种杀虫剂均产生了不同程度的抗药性,今后在这些地区进行蚊虫防治时应考虑换用其他种类的杀虫剂。

Abstract:

Objective To identify the resistance of Culex pipiens pallens to five commonly used insecticides in Xianyang city so as to provide evidence for control strategy development. Methods The mortality of larvae exposed to five insecticides was determined by the distinguishing dosage method. Results The resistance level of Cx. pipiens pallens was high under the diagnosis dose to DDT, DDVP, permethrin, and deltamethrin, and the mortality in 24 hours was 23.45%, 14.02%, 28.77%, 25.00%, respectively. The resistance to cypermethrin was moderate and the mortality was 58.63%. Conclusion The resistance of Cx. pipiens pallens to five commonly used insecticides in Xianyang has reached middle to high levels. Different kinds of insecticides should be used for control of mosquitoes.
