摘　　要：目的掌握营口市区蝇类种群构成、季节消长与肠道传染病发病的关系,为实施肠道传染病预防和控制提供科学依据。方法诱蝇笼法。结果 2011-2013年居民区和农贸市场共捕蝇3 838只,平均密度为90.38只/笼,6、8月为蝇类密度高峰期。其中最多的3种蝇类为丝光绿蝇(2 122只,55.29%)、亮绿蝇(560只,14.59%)、大头金蝇(438只,11.41%)。丝光绿蝇为主要优势种。蝇类密度与营口市主要肠道传染病发病呈正相关(r=0.521,P=0.008)。其中蝇类密度与其他感染性腹泻及细菌性痢疾发病呈正相关关系(r=0.513,P=0.009;r=0.401,P=0.036)、与甲肝、戊肝、肝炎未分型、伤寒无相关关系。结论营口市肠道传染病发病与蝇类存在相关关系,应采取相关措施,尤其是在蝇类密度高峰期,以减少或者避免由蝇类引起的肠道传染病发生。Objective To master the relationship between flies density and intestinal infectious diseases,and provide scientific basis for the prevention and control of intestinal infectious diseases. Methods Fly trap cage method. Results Totally,3 838 flies were captured in residential areas and farmers markets from 2011 to 2013,and the average density was 90. 38 pieces per cage. The flies density peaks appeared in June and August. Lucilia sericata （2 122,55.29% ） was the dominant spieces, followed by Lucilia illustris （560,14. 59% ） and Chrysomya megacephala （438,11.41% ）. Density of flies was positively correlated （ r = 0. 521, P = 0. 016 ） with main intestinal infeetious diseases incidenee in Yingkou City. The density of flies was positively correlated with other infectious diarrhea and incidence of bacillary dysentery （ r = 0. 513, P = 0. 009 ; r = 0. 401, P = 0. 036 ）. Hepatitis A and E, hepatitis, typhoid unclassifiable were not related. Conclusion Flies densty is, to some extent, correlated with intestinal infectious disease incidence in Yingkou City.
