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 understand the current situation of the resistance of Musca domestica to common hygienic insecticides in Ordos in recent years and to provide the basis for the rational use of pesticides and the guidance of insect-killing. Methods using micro-drip method. Results The natural populations of Musca domestica in Ordos City showed different degrees of resistance to dichlorvos, deltamethrin and alpha-cypermethrin, with the resistance multiples of 19.39, 48.05 and 407.69 times, respectively. The lethal rate of Musca domestica was low. Conclusion The natural population of Musca domestica in Ordos has low resistance to dichlorvos, high level of resistance to deltamethrin and alpha-cypermethrin, and low mortality to propoxur.
