摘　　要：目的掌握扬州市蝇类种群构成、密度、季节变化以及家蝇对5种杀虫剂的抗性情况,为蝇类防制工作提供理论依据。方法使用笼诱法进行蝇类生态学监测,使用点滴法进行家蝇野外种群的抗药性检测。采用Excel 2016软件对蝇类生态学监测结果进行汇总分析,采用DPS软件对家蝇抗药性结果进行统计分析。结果2023年扬州市总蝇密度为2.71只/笼,家蝇为优势蝇种,占比52.86%,密度为1.43只/笼。不同生境中以居民区蝇密度最高,为3.05只/笼。全年总蝇密度总体呈单峰分布,在7月达到高峰。扬州市家蝇对溴氰菊酯、高效氯氰菊酯、敌敌畏、辛硫磷、呋虫胺均产生了抗药性,抗性倍数分别为291.68、65.66、6.86、22.90、34.28。结论家蝇为扬州市的优势蝇种,对5种常用杀虫剂均产生了不同程度的抗药性,建议今后在蝇类防制工作中加强对杀虫剂使用的技术指导,以延缓蝇类抗药性的产生与发展。Objective To investigate the species,density and seasonal fluctuation of flies and the resistance of Musca domestica to five insecticides in Yangzhou,so as to provide a theoretical basis for fly control.Methods The cage trap method was used for fly ecological surveillance,and the topical application method was used to determine the insecticide resistance of Musca domestica.The ecological surveillance results were calculated using Excel 2016 software,and the insecticide resistance was analyzed using Data Processing System software.Results In 2023,the total fly density was 2.71 flies per cage in Yangzhou.Musca domestica was the dominant species,accounting for 52.86%,and the density was 1.43 flies per cage.The highest density of flies was found in residential area which was 3.05 flies per cage.The total fly density showed a unimodal distribution,and the peak period was July.Musca domestica showed a resistance to deltamethrin,beta-cypermethrin,dichlorvos,phoxim,and dinotefuran,and the resistance ratios were 291.68,65.66,6.86,22.90,and 34.28,respectively.Conclusion Musca domestica was the dominant species in Yangzhou,with varying degrees of resistance to five commonly used insecticides.It is suggested that the technical guidance on the use of insecticides should be strengthened in the future in order to delay the occurrence and development of fly resistance.
