目的分析锦州市蝇类组成、密度、季节消长及分布规律,为蝇类防治工作提供参考依据。方法采用笼诱法进行蝇密度监测。结果 2008-2015年锦州市共捕蝇44 401只,其中丝光绿蝇和家蝇为优势种,分别占41.07%、32.25%。捕获蝇类的总平均密度为19.82只/笼,各年平均密度分别为21.68、30.67、19.97、20.61、18.86、15.97、16.51和14.30只/笼。密度高峰在7-8月,餐饮外环境的蝇密度最高,为34.34只/笼。结论锦州地区蝇类侵害以丝光绿蝇和家蝇为主;自2011年后,蝇密度呈现小幅度下降趋势;7-8月为蝇类防治重点月份,重点的防治区域为餐饮外环境,相关部门应增加此类区域捕蝇器械,减少肠道传染病和寄生虫病的发生机率。
Objective To analyze the composition, density, seasonal fluctuation and distribution of flies in Jinzhou, and provide references for the prevention and control of flies. Methods Cage induction method was used to monitor the fly density. Results A total of 44 401 flies were collected in Jinzhou City from 2008 to 2015, of which 40.2% were dominant flies and 40.2% were house fly. The total average density of flies caught was 19.82 / cage, the average density of each year was 21.68,30.67,19.97,20.61,18.86,15.97,16.51 and 14.30 / cage. The density peak in July-August, the highest outside the catering flies density, 34.34 / cage. Conclusion The flies in Jinzhou are dominated by green flies and house flies. The density of flies decreased slightly after 2011; the flies were controlled from July to August. The key areas for prevention and treatment were catering environment, Departments should increase the number of fly-trapping devices in such areas so as to reduce the incidence of intestinal infectious diseases and parasitic diseases.
