摘要 目的了解咸阳市家蝇抗药性情况,指导科学合理的使用杀虫剂。方法采用点滴法,测定家蝇半数致死量(LD_(50))。结果咸阳市家蝇对4种常用杀虫剂的LD_(50)依次为敌敌畏0.019μg/只,高效氯氰菊酯0.098μg/只,溴氰菊酯0.013μg/只,残杀威6.627μg/只,与敏感试虫相比R/S值敌敌畏为4.71倍,高效氯氰菊酯为31.92倍,溴氰菊酯为20.63倍,残杀威为31.02倍。结论咸阳地区家蝇对4种杀虫剂均产生不同程度的抗药性,以残杀威和高效氯氰菊酯最为显著,与当地农业生产、卫生城市创建等工作中杀虫剂的使用方法不当密切相关;建议加强抗药性监测,科学合理用药,采取综合防治措施,以减缓抗药性的发展。 Objective To identify Musca domestica insecticide resistance in Xianyang city for proper application of insecticides. Methods Topical dropping method was used to determine the LD50. Results The LDs0 values of DDVP, betaeypermethrin, dehamethrin and propoxur for M. domestica were 0.019, 0.098, 0.013 and 6.627 μg/Q, respectively. The resistances ratios (R/S) to four insecticides were 4.71, 31.92, 20.63 and 31.02, respectively. Conclusion The resistance of M. domestica in Xianyang city to four insecticides in Xianyang city has developed to varying degrees, particularly that to betacypermethrin and propoxur. Development of resistance may be due to improper administration of insecticides in the agricultural and construction areas. Additional resistance monitoring, proper use of insecticides and comprehensive vector control strategies are key to preventing the occurrence of drug resistance in these vectors.
