摘要
目的了解2021年浙江省不同地区家蝇种群对常见卫生杀虫剂的抗药性现状,为蝇类防制合理用药提供科学依据。方法不同的家蝇野外种群于2021年4-11月采自浙江省杭州、宁波、温州、绍兴、湖州、嘉兴、金华、衢州、台州、丽水、舟山及义乌市的12个监测点,采用微量点滴法对菊酯类、有机磷类和氨基甲酸酯类中7种常见卫生杀虫剂进行抗药性生物测定。结果浙江省11个地级市及义乌市家蝇种群对高效氯氰菊酯、溴氰菊酯、氯菊酯、高效氟氯氰菊酯、敌敌畏、毒死蜱和残杀威的抗性倍数分别为0.83~255.00、4.44~158.78、6.11~64.81、1.76~53.57、2.45~130.11、3.37~10.39、2.52~1149.63。结论浙江省不同地区的家蝇野外种群对7种常见卫生杀虫剂中的多种已产生了不同程度的抗药性,未来蝇类防制过程中应结合抗药性监测结果,规范化管理化学杀虫剂的使用,以期在有效降低蝇密度的同时延缓抗药性的发展。
Objective To investigate the resistance of Musca domestica populations to commonly used insecticides in different regions of Zhejiang province,China,in 2021,and to provide a scientific basis for rational insecticide use of fly control.Methods Different field populations of M.domestica were collected from 12 monitoring sites in Hangzhou,Ningbo,Wenzhou,Shaoxing,Huzhou,Jiaxing,Jinhua,Quzhou,Taizhou,Lishui,Zhoushan,and Yiwu,Zhejiang province from April to November 2021.The topical application method was used to determine the resistance of M.domestica to seven commonly used insecticides of pyrethroids,organophosphorus and carbamates.Results The resistance ratios of M.domestica populations to beta-cypermethrin,deltamethrin,permethrin,beta-cyfluthrin,dichlorvos,chlorpyrifos,and propoxur were 0.83-255.00,4.44-158.78,6.11-64.81,1.76-53.57,2.45-130.11,3.37-10.39,and 2.52-1149.63 in 11 prefecture-level cities and Yiwu,Zhejiang province.Conclusion Some field populations of M.domestica in different regions of Zhejiang province have developed varying degrees of resistance to many of the seven commonly used insecticides.In the future fly control,measures should be taken to standardize the use of chemical insecticides based on the results of resistance monitoring in order to effectively reduce the density of flies and delay the development of resistance.
