Abstract: Objective To investigate the resistance of Musca domestica to five common insecticides in Wenzhou, China, and to provide a basis for scientific and rational use of insecticides and development of targeted prevention and control measures. Methods From May to October, 2017, M. domestica adults were collected from each monitoring site in Wenzhou and were then brought to the insectary for breeding. The micro-drip method was used to determine the median lethal dose (LD50) of permethrin, deltamethrin, beta-cypermethrin, dichlorvos, and propoxur for M. domestica. Results The LD50 of permethrin, deltamethrin, beta-cypermethrin, dichlorvos, and propoxur was 0.425 3, 0.262 6, 3.281 8, 9.667 9, and >48 μg/♀, respectively. Compared with the LD50 of sensitive lines, the resistance ratios were 39.38, 291.78, 911.61, 213.42, and >161.45 times, respectively. Conclusion Musca domestica in the monitoring sites has developed a high level of resistance to common insecticides, and there has been a significant increase in resistance in recent years. Therefore, scientific management and technical guidance for the use of insecticides should be strengthened.

摘要: 目的 了解温州市家蝇对5种常用杀虫剂的抗药性水平,为科学合理使用杀虫剂,制定针对性的防控措施提供科学依据。方法 2017年5-10月,在温州市各监测点采集家蝇成虫,带回实验室培育,采用微量点滴法检测家蝇对氯菊酯、溴氰菊酯、高效氯氰菊酯、敌敌畏和残杀威5种杀虫剂的半数致死剂量(LD50)。结果 氯菊酯、溴氰菊酯、高效氯氰菊酯、敌敌畏和残杀威的LD50分别为0.425 3、0.262 6、3.281 8、9.667 9和>48 μg/只;与敏感品系LD50相比,抗性倍数分别为39.38、291.78、911.61、213.42和>161.45倍。结论调查点家蝇对常用杀虫剂均产生高抗,且近年抗性增长明显,应加强杀虫剂使用的科学管理和技术指导。
