目的掌握赣榆口岸蝇类种群构成、分布、密度和季节消长,为口岸蝇类的防治提供科学依据。方法 2013年4月—2014年3月,采用蝇笼诱捕法,对赣榆口岸不同生境蝇类进行调查,并对资料进行分析。结果本次调查共捕获蝇类3 356只,经分类鉴定隶属于4科8属9种,优势蝇种为舍蝇和丝光绿蝇;蝇类密度随季节消长,蝇密度高峰期出现在6、10月;平均密度为23.31只/笼。结论赣榆口岸蝇类季节消长明显,不同生境成蝇平均密度区别明显,不同生境蝇种构成比差别明显。
Objective To understand the composition, distribution, density and seasonal fluctuation of flies in Ganyu port and provide a scientific basis for the prevention and control of fly flies at ports. Methods From April 2013 to March 2014, the flies in different habitats at Ganyu port were investigated by fly trapping method and the data were analyzed. Results A total of 3 356 flies were collected in the survey. Nine species belonging to 8 genera and 4 families were identified. The dominant flies species were Shelf flies and Lucilia sericata. The flies density decreased with season, and the flies density peaked at 6, October; the average density of 23.31 / cage. Conclusion The flies of Ganyu Port show obvious seasonal fluctuation, and the average density of adult flies in different habitats is obviously different. The differences of the composition ratio of flies in different habitats are obvious.
