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 structure, density and seasonal fluctuation of flies in different urban settlements in Hebei Province, and to analyze the differences in density and population of flies caught by different decoys. Methods Cage induction method. Results A total of 19 flies were found in 14 genera and 4 families, which were common species of housefly. The flies captured mainly by flies were mainly Muscidae, accounting for 54.22% of the total number of flies captured. The flies caught by brown sugar and vinegar were mainly flies Branch and Reinaeidae, accounting for 39.17% and 36.08% respectively. The seasonal changes of the density of flies caught by the three kinds of baits with rotten fish, stinky tofu and brown sugar and sweet vinegar were similar, with the peak of density occurring in August. Conclusion The main fly species for controlling flies in Hebei Province are Drosophila melanogaster, Lucilia sericata, Musca domestica, Monochamus alternatus and Stable flies. Environmental regulation is the fundamental measure to control the flock population density in urban settlements. The rotten fish is the more suitable decoy in the flies routine monitoring.
