【摘要】 目的对昌平区特殊行业家蝇抗性进行测定。方法采用药膜法对采自我区家蝇进行DDVP、残杀威和高效氯氰菊酯的抗性测定。结果该地区家蝇对DDVP的LD50为6.271 963(4.745 079~8.290 173)μg/只,抗性系数达315.33,残杀威的LD50为0.424 357(0.315 863~0.570 119)μg/只,抗性系数达223.35,对高效氯氰菊酯LD50为0.029 753(0.023 052~0.038 403)μg/只,抗性系数为57.22。结论该地区家蝇对3种杀虫剂抗性均达到了高抗性水平,对DDVP抗性最高。建议该地区停止有机磷类药物的使用,减少菊酯类和氨基甲酸酯类药品的使用。更多还原

【Abstract】 Objective To investigate the resistance of Musca domestica in special industry in Changping district. Methods Membrane method was used to test the resistance of Musca domestica to DDVP,propoxur and Beta-cypermethrin.Results The resistance coefficient to DDVP,propoxur and Beta-cypermethrin were 315.33(LD50=6.271 963 μg,4.745 079～8.290 173),223.35(LD50=0.424 357μg,0.315 863～0.570 119),57.22(LD50=0.029 753 μg,0.023 052～0.038 403) respectively.Conclusion The resistance of Musca domestica to insecticides in Changping district was on high level,especially to DDVP.Organophosphorus insecticides should be forbidden for using in this district,pyrethrin and carbamates series should be used less.更多还原
