摘要
目的调查三门峡市区家蝇对4种常用杀虫剂的抗药性状况,为科学合理使用卫生杀虫剂控制家蝇提供科学依据。方法用微量点滴法测定LD50,对家蝇抗性进行评价。结果2007年三门峡市区家蝇对溴氰菊酯、敌敌畏、二氯苯醚菊酯和高效氯氰菊酯均产生抗性,抗性倍数分别为120.17、69.02、65.91和59.78倍。结论三门峡市区家蝇对溴氰菊酯、敌敌畏、二氯苯醚菊酯和高效氯氰菊酯均产生了极高抗性,其中以溴氰菊酯的抗性最高。根据抗药性调查结果,以轮换或混合使用杀虫剂,使家蝇抗性得到控制,从而提高杀虫剂灭蝇效果。病媒生物控制应以环境治理为主,辅之以化学防治、生物防治、物理防治和法规防治,利用综合防治措施来有效防治家蝇的危害。
Objective To investigate the resistance of housefly, Musca domestica, to four insecticides in Sanmenxia city so as to provide the science evidence for the reasonable use of insecticides. Methods The resistance of house fly was determined by the traditional topical dropping method. Results The resistances ratios （R/S） of housefly to dehamethrin, DDVP, permethrin and Beta-cypermethrin were 120.17, 69.02, 65.91, and 59.78, respectively. Conclusion Housefly had high resistance to four common insecticides, highest to deltamethrin. It suggested that the rotational and mixed use of insecticides could control effectively housefly. The emphasis of housefly control will be put on the environment improvement, and the integrated pest management strategy will be the best effective way to control housefly.
