摘要
目的了解鄂尔多斯市近年来家蝇自然种群对常用卫生杀虫剂的抗药性现状,为合理使用杀虫剂和指导灭蝇工作提供依据。方法采用微量点滴法。结果鄂尔多斯市家蝇自然种群对敌敌畏、溴氰菊酯、高效氯氰菊酯已呈现出不同程度的抗药性,抗性倍数依次为19.39、48.05和407.69倍,残杀威对家蝇的致死率较低。结论鄂尔多斯市家蝇自然种群对敌敌畏的抗药性较低,对溴氰菊酯和高效氯氰菊酯呈现高抗水平,对残杀威致死率较低。
Objective To determine current resistance to commonly used insecticides in the natural population of Musca domestica in Ordos city, in order to evidence for proper application of insecticides for fly control. Methods Topical application method was used in the study. Results The natural populations of M. domestica in Ordos city had developed various degrees of resistances to diehlorovos, deltamethrin and beta-cypermethrin, with resistance ratios of 19.39, 48.05, and 407.69, respectively. Propoxur resulted in low fatality in M. domestica. Conclusion The natural populations of M. domestica in Ordos city had low resistance to dichlorovos and high resistance to deltamethrin and beta-cypermethrin. Propoxur had a low lethality rate in the flies.
