河北省不同城市住区蝇类密度及不同诱饵监测结果分析

Analysis on the flies density monitored with different baits at different residential areas of Hebei province

目的对河北省不同城市住区蝇类种群构成、密度及季节消长进行监测,分析比较不同诱饵诱捕蝇类密度及种群的差异。方法笼诱法。结果共捕获蝇类4科14属19种,以家蝇为常见种;腐鱼作诱饵捕获的蝇类以蝇科为主,占捕获总数的54.22%;红糖醋作诱饵捕获的蝇类以蝇科和丽蝇科为主,分别占39.17%和36.08%;腐鱼、臭豆腐和红糖醋3种诱饵捕获的蝇类密度季节消长规律基本相似,密度高峰期均出现在8月。结论河北省城市蝇类防制的主要蝇种是大头金蝇、丝光绿蝇、家蝇、棕尾别麻蝇和厩腐蝇。环境整治是控制城市住区蝇类种群密度的根本措施。腐鱼是住区蝇类常规监测中较为适宜的诱饵。

Objective To monitor the population density and seasonal fluctuation of flies at different areas of Hebei, and compare the trapping efficacy of different baits. Methods Cage trapping method was used in this study. Results A total of 19 species were caught, belonging to 4 families, 14 genera. Musca domestica was dominant specie. Muscidae were mainly trapped with putrid fish, accounting for 54.22% of the total. Muscidae and Calliphoridae were mostly caught with a mixture of brown sugar and vinegar, accounting for 39.17% and 36.08%, respectively. The season fluctuation tendency of flies caught with two baits was similar, and the peak was all in August. Conclusion According to the surveillance data, the species controlled mainly are M.domestica, Chrysomya megacephala, Lucilia sericata, Boettcherisca peregrine and M.stabulans. Environment improvement and the reduction of bleeding sites are the basic measures to control fly density. The putrid fish is worthy to be recommended as a surveillance method of flies density.
