目的了解和掌握沈阳市蚊虫和蝇类密度及季节消长规律,为虫媒传染病的预防控制提供技术支持。方法蚊虫监测采用诱蚊灯法;蝇类监测采用笼诱法。结果 2011-2014年共捕获蚊类8572只,平均蚊密度为4.46只/(灯·h),淡色库蚊为优势蚊种,占捕蚊总数的73.74%。不同生境蚊密度牲畜棚>农户>居民区>医院>公园。沈阳市蚊密度季节消长明显,活动高峰一般在7-9月;2011-2014年共捕获蝇类16 119只,平均蝇密度为6.40只/(笼·h),隶属5科13属14种。以丝光绿蝇为优势种,其次为厩腐蝇、家蝇、黑尾黑麻蝇、红头丽蝇、红尾粪麻蝇、棕尾别麻蝇;蝇密度呈现逐年上升趋势,2014年蝇密度是2011年的6.4倍;蝇密度高峰期在6-8月;不同生境蝇密度依次是绿化带>农贸市场>居民区>餐饮店外环境。结论基本掌握了沈阳市蚊虫和蝇类密度、种类构成、季节消长情况。长期系统地对蚊虫和蝇类密度监测,为合理制定蚊蝇类综合防制策略提供科学依据。
Objective To understand and master the mosquito and flies in Shenyang City, the density and the law of the growth and decline, provide the technical support for the prevention and control of the vector-borne diseases. Methods The mosquito lamp method was used to monitor the mosquitoes. Cage method was used to monitor the flies. Results A total of 8,572 mosquitoes were collected from 2011 to 2014, with an average mosquito density of 4.46 / (lamp · h). Culex pipiens pallens dominant mosquito species accounted for 73.74% of the total mosquito catch. Mosquito density of different habitats shed> farmers> residential areas> hospitals> parks. The density of mosquito densities in Shenyang varied significantly from the 7th to the 9th month. From 2011 to 2014, a total of 16,119 flies were collected, with an average flies density of 6.40 / (cage · h) and 14 species belonging to 13 genera, 5 families. The dominant flies were Lucilia sericata, followed by stable flies, house flies, black-tailed black flies, red flies, red tail dung flies and brown flies. The density of flies tended to increase year by year. 6.4 times; flies density peak in June-August; different habitat density followed by green belt> farmers’ market> residential area> outside the restaurant environment. Conclusion The density, species composition and seasonal fluctuation of mosquitoes and flies in Shenyang are basically mastered. Long-term and systematic monitoring of mosquitoes and flies density, to provide a scientific basis for the rational development of mosquito flies integrated control strategy.
