Abstract:

Objective To explore the status of mosquito infestation in different types of residential areas in downtown Shanghai, and to analyze the causes and countermeasures. Methods Selecting 3 mosquito monitoring sites from 3 different types of downtown neighborhoods in the same area, conduct 224 days’ continuous mosquito monitoring in CO2-light trapping method. Results Aedes albopictus is the predominant mosquito population in residential areas of downtown Shanghai (account for 72.35%), significantly higher than the density of sub-dominant Culex pipien pallens population (11.91 vs. 4.21/day·machine, P<0.05); Compared with the type of high-rise residential and old-fashioned villas environments, the old neighborhood environment faced more serious mosquito-infestation conditions, which has significantly higher mosquito density (total mosquito density, 28.91/day·machine, P<0.05), and much higher Ae. albopictus proportion (76.60%, P<0.05). Conclusion The situation of Ae. albopictus infestation in residential areas of downtown Shanghai is quite concerned, especially in old neighborhoods, whose living conditions and sanitary facilities are relatively poor. It is recommended that countermeasures should be taken to cope with the threat of Ae. albopictus-borne infectious disease in residential areas.

摘要:

目的 探索上海城区不同住区类型蚊虫侵害的特点, 分析原因及提出防治对策。方法 选取上海市中心城区同一区域3个不同住区类型设置CO2捕蚊机监测点, 于2013年4-11月进行224 d连续性成蚊监测。结果 监测结果显示, 上海城区住区环境白纹伊蚊占捕蚊总数的72.35%, 为优势蚊种, 密度显著高于次优势蚊种淡色库蚊〔11.91 vs. 4.21只/(台·d), P<0.05〕;旧式里弄环境的成蚊密度、白纹伊蚊构成比均显著高于高层住宅与老式别墅环境〔成蚊密度28.91只/(台·d), 构成比为76.60%, 均P<0.05〕。结论 住区是城市中人口较集中的区域, 上海城区住区环境的白纹伊蚊侵害状况不容乐观, 尤其在环境相对较差的旧式里弄环境, 该蚊侵害及其介导传染病的潜在威胁需引起重视。
