晋江围头港蝇类初步调查

目的掌握晋江围头港的蝇类构成、季节消长情况,为开展口岸卫生监督和蝇类防制工作提供科学依据。方法从2004．9-2005．8采用捕蝇笼诱捕法对围头港蝇类的种群组成、密度及季节消长情况进行初步调查。结果此次调查共捕获蝇类17 978只,年平均蝇密度为99．88只／笼·日,经鉴定隶属4科11属16种,其中以家蝇为优势种,占捕获总数的36．02％;其次为元厕蝇和中华海花蝇,分别占捕获总数的18．13％和12．24％,蝇密度季节消长呈双峰型,以10月为最高,达到234．93只／笼·日。不同生境蝇类密度有差别,以食堂的为最高,达186．28只／笼·日。结论在围头口岸的蝇类密度控制方面,要以家蝇、元厕蝇、中华海花蝇、大头金蝇为主要监控对象;同时根据不同时间、地点采取相应的消杀灭措施。
