摘　　要：目的了解沈阳市的蝇密度、种群构成及其季节消长变化的规律,为蝇类防治提供依据.方法采用笼诱法,于2019-2023年每年的5-10月在不同生境进行监测.结果2019-2023年沈阳市共布放蝇笼245个,捕蝇15739只,属5科9属12种,年平均密度为64.24只/笼,不同生境蝇密度依次为绿化带、居民区、农贸市场、餐饮外环境,不同年度、不同生境均以丝光绿蝇和厩腐蝇为优势种,分别占捕获总数的38.52%、23.66%.2019-2023年蝇类季节消长均呈单峰曲线,蝇密度在6-8月达到高峰后逐渐下降,10月蝇活动减弱.结论沈阳市蝇类主要集中在绿化带及居民区,6-8月为蝇类活动高峰,在蝇类防治过程中应结合季节消长规律,采取针对性措施,有效降低蝇密度.Objective To understand the density,population composition and seasonal variation of flies in Shenyang,and to provide the basis for fly control.Methods The cage trapping method was adopted for the investigation of flies in different habitats from May to October each year from 2019 to 2023.Results From 2019 to 2023,a total of 245 fly cages were placed in Shenyang,and 15739 flies were captured,belonging to 12 species of 9 genera,5 families,with an annual average density of 64.24 flies/cage.The density of flies in different habitats were mainly green belt,residential area,farmer's market and outside dining environment,and Lucilia sericulata and Muscina stabulans were the dominant species accounting for 38.52%and 23.66%.The seasonal fluctuation of flies showed a unimodal curve from 2019 to 2023.The density of flies gradually decreased after reaching a peak from June to August,and the activity of flies decreased in October.Conclusion In Shenyang,flies are mainly in the green belt and residential areas,and the peak of fly activity is from June to August.In the process of fly control,targeted measures should be taken based on the seasonal dynamics.
