摘要: 目的:了解蚊虫对常用杀虫剂抗药性发展趋势。方法:在济宁市区采集淡色库蚊,采用区分剂量法和WHO浸渍法测定每种杀虫剂致蚊虫的死亡率和半数致死浓度(LC50),并计算抗性指数。结果:淡色库蚊对DDVP和溴氰菊酯抗药性较强,DDVP抗性指数由8.30倍上升到20.63倍,溴氰菊酯波动在13.09~44.21倍之间,对DDT由1.11倍上升到11.53倍,对马拉硫磷由1.76倍上升到6.16倍,氯菊酯在3.04~5.40倍之间。结论:淡色库蚊对常用化学杀虫剂均产生不同程度的抗药性,在现场应用中应科学合理地选用杀虫剂。

Abstract: Objective: To explore the development trend of resistance of Cx. pipiens pallens against commonly used insecticides. Methods: Diagnostic method and WHO bioassay were used to test Cx.pipiens pallens larvae from Jining. Results:Cx.pipiens pallens revealed strong resistance towards DDVP and deltamethrin, with resistant index being 8.30-20.63 and 13.09 - 44.21 respectively. The resistant index of DDT, malathion and permethrin was 1.11 - 11.53 , 1.76 - 6.16 , 3.04 - 5.40 respectively. Conclusion: Cx.pipiens pallens produced resistance at various level to commonly used insecticides. Scientific and rational use of insecticides was recommended.
