Abstract

Abstract: Objective To investigate the common species, densities and seasonal fluctuation of flies in human settlements and surroundings in Henan province, China, in 2020, and to provide a basis for scientific prevention and control. Methods The data of flies captured by the cage trapping method were collected from fly surveillance in Henan province, from April to October in 2020. Descriptive methods were used for statistical analysis. Residential areas, catering environment, greenbelts, and farm product markets were chosen for the investigation. Results In 2020, the total density of flies in Henan province was 8.39 flies/cage, and the dominant species were Musca domestica (41.49%), Muscina stabulans (19.26%) and Sarcophagidae (11.00%). The highest density of flies was found in farm product market (10.43 flies/cage). The seasonal fluctuation of the total density of flies showed a unimodal distribution and reached the peak in June. Among the dominant fly species, M. domestica, M. stabulans, and Sarcophagidae had the similar seasonal fluctuation trends to the total density of flies. Conclusion According to the composition and seasonal fluctuation of flies in human settlements and surroundings in Henan province, it is suggested that reasonable prevention and control measures should be taken according to the surveillance results in the districts or counties at each surveillance site to reduce fly infestation and fly-borne diseases.

摘要： 目的了解河南省2020年人居及周边环境蝇类常见种类、密度及季节消长，为科学防控提供依据。方法 2020年4-10月选择居民区、餐饮外环境、绿化带、农贸市场4类生境，采用笼诱法进行蝇类监测，获取的数据进行描述性分析。结果 2020年河南省蝇类总密度为8.39只/笼，优势蝇种为家蝇、厩腐蝇和麻蝇，分别占41.49%、19.26%和11.00%；不同生境中农贸市场蝇类密度最高，达10.43只/笼；蝇类总密度季节消长呈单峰分布，6月达高峰，优势蝇种家蝇、厩腐蝇、麻蝇的消长趋势与蝇类总密度趋势相似。结论根据河南省人居及周边环境蝇类构成及季节消长，建议各监测点区（县）根据监测结果采取合理的防控措施，减少蝇类骚扰和蝇传疾病的发生。
