武汉市江夏区蝇类种群动态调查研究

Survey on dynamic of fly in Jiangxia district in Wuhan

目的了解江夏区纸纺街2010年蝇类的种群动态,为蝇传疾病的预防和灭蝇工作提供理论依据。方法蝇类采用笼诱法。结果蝇类有4科7属11种,家蝇、丝光绿蝇、大头金蝇和巨尾阿丽蝇为优势种,分别占蝇类总数的34.8%、18.4%、13.7%和13.4%;家蝇密度季节消长曲线呈双峰状,丝光绿蝇和大头金蝇呈单峰状,而巨尾阿丽蝇呈多峰状。年均蝇密度为:农贸市场>绿化带>餐饮外环境>居民区。优势蝇种优势度季节消长曲线和密度季节消长基本一致。结论家蝇、丝光绿蝇和大头金蝇为主要防治对象,全区5-11月应开展灭蝇工作。

Objective To provide theoretical foundation for fly control by investigating dynamic of adult fly in Wuhan in 2010.Methods Cage trap to catch flies.Results The results showed that 11 species fly were distributed in 7 genera under 4 family.The dominant species were Musca domestica,Lucilia sericata,Chrysomyia megacephala and Aldrichina grahami,accounted for 34.8%,18.4%,13.7% and 13.4% respectively.The density seasonal fluctuation of Musca domestica had two peaks,Lucilia sericata and Chrysomyia megacephala only one peak,and Aldrichina grahami had several peaks.Density of fly： marketplaces green belts outside of restaurants residential areas.The dominant species seasonal fluctuation of dominanc and density were similar basically.Conclusion Objects of fly control are Musca domestica,Lucilia sericata and Chrysomyia megacephala,and fly control can be carried out from May to October in Jiangxia district.
