【摘要】 目的 调查北京市通州区卫生蝇类种群构成、密度及季节消长情况，为卫生蝇类防治提供科学依据。方法 2024年3-11月，采用笼诱法在通州区农贸市场、居民区和公园3种生境调查蝇类的种类、密度及季节消长，捕获的蝇类采用形态学鉴定。结果2024年3-11月共监测39次，捕获卫生蝇类30种8 322只，总密度24.05只/笼，其中麻蝇科14种3 625只。卫生蝇种数量排名前3位的是丝光绿蝇(1 484只)、白头亚麻蝇(1 293只)和厩腐蝇(1 041只)；公园的卫生蝇类密度最高，为29.93只/笼；其次为农贸市场(21.43只/笼)，居民区的卫生蝇类密度最低，为20.84只/笼。结论 北京市通州区卫生蝇类优势种是有丝光绿蝇、白头亚麻蝇和厩腐蝇，且公园卫生蝇类密度大，应采取综合防制措施，降低卫生蝇类密度。更多还原

【Abstract】 Objective To investigate the population composition,density and seasonal fluctuations of sanitary flies in Tongzhou District,Beijing,to provide scientific basis for the prevention and control of sanitary flies. Methods From March to November2024,the cage trapping method was used to investigate the species distribution,density and seasonal fluctuation of flies in three habitats,including farmers’ market,residential area and parks in Tongzhou District. The captured flies were identified using morphological identification. Results A total of 39 surveillance sessions were conducted from March to November 2024,capturing 8 322 sanitary flies belonging to 30 species,with an overall density of 24.05 flies per cage. Among these,there were14 species in Sarcophagidae,totaling 3 625 individuals. The top three sanitary fly species in terms of population size were Lucilia sericata(1 484),Parasarcophaga albiceps(1 293)and Muscina stabulans(1 041). The density of sanitary flies was the highest in parks,reaching 29.93 flies per cage,followed by farmers’ market(21.43 flies per cage),while residential area had the lowest density at 20.84 flies per cage. Conclusion The dominant species of sanitary flies in Tongzhou District,Beijing were Lucilia sericata,Parasarcophaga albiceps and Muscina stabulans. The density of sanitary flies was high in the park. Comprehensive prevention and control measures should be taken to reduce the density of sanitary flies.更多还原
