摘　　要：目的了解大连市农贸市场、餐饮外环境、绿化带和居民区等不同生态环境蝇类种群构成及其季节变化规律,为蝇类防制提供科学依据。方法 2011年4-11月采用捕蝇笼法调查不同环境蝇种构成和种群密度、重要蝇种季节消长。结果大连市常见蝇种有4科8亚科12属15种,优势种依次为丝光绿蝇、厩腐蝇、巨尾阿丽蝇、家蝇、黑尾黑麻蝇,平均密度指数为19.04,蝇类活动高峰期为6～9月,不同生态环境密度指数最高的为居民区(39.96),其次是绿化带(32.08)、农贸市场(13.67),最低的为餐饮外环境(4.75)。结论大连地区蝇类种群密度较高,活动季节较长,种类较丰富。防治工作应以5～10月为重点,并充分考虑丝光绿蝇、厩腐蝇、黑尾黑麻蝇、大头金蝇、家蝇的生活习性。Objective To understand the population structure and seasonal fluctuation of flies in farmers＇ market,external environment of restaurant,green belt and residential areas in Dalian city,and provide scientific basis for the control of flies.Method Investigate the composition,density and seasonal fluctuation of flies in different environments from April to November by cage trap method.Results The usual flies in Dalian belonged to15 species,12 genera in 4 families.The dominant species were lucilia sericata,muscina stabulan,aldrichina grahami,musca domestica,belleria melanura,and the average density index was 19.04.The peak of flies was usually from June to September.The environment with the largest density was residential area（39.96）,followed by green belt（32.08）,farmers＇ market（13.67）,and external environments of restaurants（4.75）.Conclusions The density of flies in Dalian was higher,their active time was longer,and the species were abundant.The key control time was from May to October.In the control of flies,the living habit of lucilia sericata,muscina stabulan,aldrichina grahami,musca domestica,belleria melanura should be taken into account.
