Abstract:

Objective In order to understand the insecticide resistance of Musca domestica to five different commonly used insecticides in Huairou district from 2014 and 2016, and provide the basis for scientific and reasonable guidance on the selection of insecticides for its control program. Methods The drug resistance test was carried out using the membrane method, and the experimental data were analyzed by PROBIT model in SPSS(21.0) software. Results In 2014 and 2016, the wild population of M. domestica in Huairou district was susceptible to DDVP, and the resistance were 0.23 and 0.25-fold,respectively. The resistance to Deltamethrin was high, and the resistance were 157.62 and 37.15-fold, respectively; resistance to Beta-cypermethrin were very high in both years, the resistance were 181.64 and 289.06-fold, respectively. In 2016, the resistance level to Propoxur changed from low to high, and increased by 4.15 times compared to 2014; the resistance level to Chlorpyrifos was decreased by 33.58 times from low resistance to being susceptible. Conclusion The M. domestica in Huairou district showed high or extremely high resistance to pyrethroid insecticides. The resistance to DDVP and Chlorpyrifos should be further monitored and determined. Integrated control measures should be taken to control fly species.

摘要：

目的 了解2014和2016年北京市怀柔区家蝇对5种常用杀虫剂的抗药性情况，为科学合理选用杀虫剂提供依据。方法 2014和2016年采集怀柔区家蝇野外种群进行饲养，繁殖1代，待羽化为成虫后采用药膜法进行抗药性测定，采用SPSS 21.0软件中PROBIT模型对数据进行分析。结果 2014和2016年怀柔区家蝇野外种群对DDVP均敏感，抗性倍数分别为0.23和0.25倍；对溴氰菊酯均为高抗，抗性倍数分别为157.62和37.15倍；对高效氯氰菊酯均为极高抗，抗性倍数分别为181.64和289.06倍。2016年家蝇对残杀威的抗性级别由低抗转为高抗，抗性倍数较2014年增加了4.15倍；毒死蜱的抗性级别由低抗降为敏感，抗性倍数下降了33.58倍。结论 怀柔区家蝇对拟除虫菊酯类杀虫剂产生了高抗或极高抗，对DDVP和毒死蜱的抗性待进一步监测确定；应采取综合防制措施控制蝇类。
