目的查明舟山本岛北部港区蝇类本底情况,为预防控制蝇传虫媒病与输入性媒介生物的入侵提供科学依据。方法 2012—2014年,在舟山本岛北部港区分别选择码头区、生产区、办公区3种代表性环境,采用诱蝇笼法对蝇类本底情况进行调查。结果本次调查共捕获蝇类20 218只,经分类鉴定隶属于5科11属18种,优势种群为丝光绿蝇;蝇类平均密度为11.70只/笼·h,在5月和10月达到高峰期。结论本次调查初步查明了舟山本岛北部港区范围内蝇类的本底情况,为口岸蝇类防治工作提供了依据。
Objective To identify the background of flies in the northern port area of Zhoushan island and provide a scientific basis for the prevention and control of insect-borne flies and invasion of imported vector organisms. Methods From 2012 to 2014, three representative environments of wharf area, production area and office area were selected in the northern port area of Zhoushan Island, respectively. The fly flies cage method was used to investigate the background of flies. Results A total of 20 218 flies were collected from this survey. 18 species belonging to 11 genera and 5 families were identified. The dominant species was Lucilia sericata; the average density of flies was 11.70 / cage h, reached in May and October Peak period. Conclusion The investigation initially identified the background of flies in the northern port area of Zhoushan Island and provided the basis for the prevention and control of flies in ports.
