Abstract: Objective To investigate the resistance ofCulex pipiens quinquefasciatusandMusca domesticato commonly used insecticides in Changsha, Yiyang, and Yueyang, Hunan province, China in 2011, and to provide a scientific guidance for the management of mosquitoes and houseflies.Methods The resistance of mosquitoes and houseflies to insecticides was determined by larval immersion and topical application, respectively.Results Cx. pipiens quinquefasciatusshowed resistance to all insecticides tested with the following resistance ratios: 1.14-2.86 fold to deltamethrin, 2.25-6.75 fold to beta-cypermethrin,1.00-17.24 fold to fenobucarb, and 25.00-65.00 fold to temephos, of which temephos resistance was the highest. Musca domesticawas also resistant to all insecticides tested in this study, with resistance ratios as follows: 36.13-109.13 fold to deltamethrin, 28.46-32.81 fold to beta-cypermethrin, 1.43-2.25 fold to DDVP, and 0.82-2.34 fold to propoxur; the resistance to chrysanthemum ester was the highest, with a peak value of 109.13 fold.Conclusion More efforts should be made to the resistance ofCx. pipiens quinquefasciatusandM. domesticato insecticides. It is necessary to enhance resistance monitoring and to use insecticides rationally, so as to prevent and reduce the development of pesticide resistance.

摘要: 目的 了解湖南省长沙、益阳、岳阳市蚊、蝇对高效氯氰菊酯、溴氰菊酯、仲丁威、双硫磷、敌敌畏和残杀威6种常用杀虫剂的抗药性情况,为蚊、蝇防治提供科学依据。方法 蚊虫抗药性检测采用幼虫浸渍法,家蝇采用点滴法。结果 致倦库蚊对溴氰菊酯、高效氯氰菊酯、仲丁威、双硫磷的抗性倍数分别为1.14~2.86、2.25~6.75、1.00~17.24和25.00~65.00倍,均已产生抗性,其中对双硫磷抗性最高;家蝇对溴氰菊酯、高效氯氰菊酯、敌敌畏、残杀威的抗性倍数分别为36.13~109.13、28.46~32.81、1.43~2.25和0.82~2.34倍,亦均产生抗性,其中对菊酯类药物抗性较高,抗性倍数最高的达109.13倍。结论 各地应高度重视蚊、蝇对杀虫剂的抗药性;加强抗性监测,合理地使用杀虫剂,预防或减缓蚊、蝇对杀虫剂抗性的产生和发展。
