摘要 [目的]掌握永康市蝇密度和季节消长等动态变化规律,为蝇类及其传播疾病的控制提供依据。[方法]采用笼诱法进行蝇类监测,4—11月份每月监测1次,每次选择农贸市场1处、餐饮外环境2处、绿化带1处、居民区1处作为固定监测点。[结果]2009—2011年监测点共捕获蝇类681只,平均蝇密度为5.68只/笼,主要优势蝇种为家蝇、铜绿蝇、市蝇;蝇密度从高到低依次为农贸市场、餐饮外环境、居民区、绿化带;季节消长呈单峰型曲线,在7、8月出现高峰。[结论]永康市城区存在多种媒介蝇,建议加强蝇类综合监测,降低蝇密度,控制蝇传疾病。 [ Objective ] To get an insight into the distribution and seasonal fluctuations of the fly density and provide the basis for the control of flies and fly-borne diseases in Yangkang City. [ Methods] Fly density monitoring was conducted from April to November once a month by cage traps. Each time, one monitoring spot was selected in farmers" market , two in restaurant-surrounding areas, one in city green belt and one in residential area, these were as the fixed monitoring points. [ Results] A total of 681 flies were captured from 2009 to 2011 with an average fly density of 5.68/cage, of which the dominant spe- cies were Musca domesic, L. cuprina, M. sorbens. Their habitats listed in terms of the fly density in de- scending order of density were farmers" market, dining environment, residential community and green belt. The seasonal fluctuations of fly density followed a single-peaked curve, the high peak of which appeared in July and August. [ Conclusion] There are several fly species in Yangkang City that can transmit dis- ease, so it is important to strengthen the integrated monitoring to reduce the fly density for the control of fly- borne diseases.
