Objective To investigate the resistance of Aedes albopictus to five insecticides and provide evidence for rational application of insecticides.Methods WHO-recommended larva dipping method was used to test medium lethal concentration of the larvae at their fourth instar in this test, exposed to the five commonly used inseticides and to assess the levels of resistance in Ae. albopictus. Results The LC50 of abate, deltamethrin, betacypermethri, and fenobucarb was 0.001 3, 0.001 4, 0.005 1, and 1.568 5 mg/L. The average resistance was 4.3, 1.4, 2.4, and 1.0 fold. Resistance to acetofenat was so high, beyond the test range. Conclusion In Wuhan city, the field monitoring of Ae. albopictus on insecticide resistance is crucial for the prevention and control of dengue fever. It was necessary to apply integrated measures and use insecticides scientifically in controlling Ae. albopictus.

目的 了解武汉市白纹伊蚊对5种卫生杀虫剂的抗性情况,为科学使用杀虫剂提供依据。方法 采用世界卫生组织提供的幼虫浸渍法,测定4龄蚊幼虫的半数致死浓度(LC50),评价卫生杀虫剂的抗药性。结果 白纹伊蚊野外种群对双硫磷、溴氰菊酯、高效氯氰菊酯和仲丁威的LC50分别为0.001 3、0.001 4、0.005 1和1.568 5 mg/L,是敏感品系的4.3、1.4、2.4和1.0倍。三氯杀虫酯的抗性极高,超出可测定范围。结论 监测武汉市野外白纹伊蚊对常用卫生杀虫剂的抗药性水平及变化趋势对于防控登革热意义重大。在灭蚊工作中应采取综合性防治措施,科学合理地使用杀虫剂。
