Abstract: Objective To investigate the breeding situation of flies in different environments in Wuhan and to provide scientific evidence for fly control. Methods To investigate the breeding situation of flies in different environment in Wuhan from May to October 2016 by visual method. The fly larval breeding rates between different months were compared with χ² test. Results A total of 5 094 breeding sites were found, and there were 320 fly larval breeding sites, with a mean fly larval breeding rate of 6.3%. The fly larval breeding rate in different environs ranged from 0 to 16.8%. In the demolition site, the fly larval breeding rate was the highest, accounted for 16.8%, followed by the refuse transfer station 13.5%, the public greenbelt 12.9%, the construction site 12.6%, the railway line 12.4%, the farm produce market 8.9%, the real estate district 7.9%. The breeding rate of fly larvae in food processing plants was the lowest, i.e. 0. The fly larval breeding rate in May was the highest, accounted for 7.8%, and lowest in October, accounted for 5.7% (χ²=2.967, P=0.085). Conclusion To master the breeding situation of flies in different environments of each type of habitat in Wuhan city, to provide good background information for the prevention and control of flies in the future, as well as disease vector management in hygienic city campaign.

摘要： 目的 调查武汉市2016年城区不同环境中蝇类孳生现状，为该市科学防控蝇类提供本底资料。方法 2016年5-10月对武汉市城区蝇类孳生环境采用目测法开展现场调查。不同月份间蝇类幼虫孳生率比较采用χ²检验。结果 共调查各类型蝇类孳生地5 094处，其中有蝇类幼虫孳生的320处，平均蝇类幼虫孳生率为6.3%，不同类型环境的蝇类幼虫孳生率为0~16.8%。以拆迁工地的蝇类幼虫孳生率最高，达16.8%，其次是垃圾转运站（13.5%）、公共绿地（12.9%）、建筑工地（12.6%）、铁路沿线（12.4%）、农贸市场（8.9%）和物业小区（7.9%）；食品加工厂未发现蝇类幼虫孳生。5月蝇类幼虫孳生率最高，为7.8%，10月最低，为5.7%，各月份蝇类幼虫孳生率差异无统计学意义（χ²=2.967，P=0.085）。结论 初步掌握了武汉市城区不同环境的蝇类孳生情况，为蝇类的科学防控以及创建卫生城市中的病媒生物防制工作提供了本底资料。
