摘　　要：目的了解宁德市苍蝇种类及其携带肠道病原菌的状况,为今后防制提供依据。方法城区以诱蝇笼诱捕蝇类;野外用昆虫网捕获,分类鉴定,计算种群密度、季节消长、病原菌分离情况。结果宁德市捕获蝇类隶属6科51属115种。苍蝇密度平均为234.9只/(日.笼),垃圾场和屠宰场密度最高。蝇类全年均有活动,4-5月和10月出现2次密度高峰,5个常见蝇种病原菌分离率高达100%,与肠道传染病的流行季节相吻合。结论垃圾场和屠宰场是宁德市蝇类最为重要的孳生环境,4和10月是预防和控制肠道传染病的重要环节。Objective To investigate species, distribution of flies and the intestinal bacteria borne by the flies in Ningde to provide a basis for controlling flies and preventing infestinal infectious diseases, Methods Using cages to entrap files in urban and insect nets to catch them outside the urban three times every month, classifying them and then caculating the group density and isolating pathogenic bacteria, Results 115 species were caught belonging to 51 genera and 6 families and the average density of flies was 234,9 per cage with the highest density at garbage dump and slaughter house, Files were active throughout the year and there were 2 peaks of the density in April-May and October, with bacterium positive rates of five common flies reaching nearly I00% , which accorded with the peak seasons of intestinal infectious diseases. Conclusion Garbage dump and slaughter house are especially notable circumstance and April and October are important seasons for controlling flies and preventing intestinal infectious diseases in Ningde,
