Abstract: Objective To study the distribution of Aedes albopictus on different floors in multi-story residential buildings and the differences in its distribution between households and public environments, and to provide a scientific basis for the development of Ae. albopictus control measures. Methods Breteau index (BI) was used for monitoring Ae. albopictus in the residential areas of Nanjing, Nantong, Suzhou, Wuxi, Xuzhou and Yancheng cities from May to October in 2020, in Jiangsu province, China. SPSS 15.0 software was used to compare the differences in mosquito density between different floors and between households and public environments in residential areas. BI was compared using the Mann-Whitney U rank sum test or Kruskal-Wallis H rank sum test, and positive breeding rate was compared using the Chi-square test. Results In households, water containers mainly included aquatic plant vases, water storage containers, bonsai tray, and idle containers. Aquatic plant vases had the highest number and idle containers had the highest breeding rate of Ae. albopictus larvae. In households, BI and positive breeding rate were 9.17 and 10.79%, respectively, which were closely related to floor and the presence or absence of open spaces. The BI and positive breeding rate of the first floor were 6.39-21.48 and 4.03-11.01 times those of floors 2-6, respectively. There were no statistical differences in BI and positive breeding rate between floors 2-6 (all P>0.05). BI and positive breeding rate in households with open spaces were 16.86 and 4.88 times those in households without open spaces, respectively. In public environments, water containers mainly included idle containers, water storage containers, bonsai tray, and greenbelt garbage/water-holding wastes. Idle containers had the highest number and water storage containers had the highest positive breeding rate of Ae. albopictus. BI and positive breeding rate in public environments were 46.22 and 26.01%, which were 5.04 and 2.41 times those in households, respectively. Conclusion Ae. albopictus mainly breeds in public environments and first-floor households with open spaces in residential areas in Jiangsu province. In case of dengue outbreak, control measures should be taken in public environments and first-floor households with open spaces; Attention is also needed for the possible spreading of Ae. albopictus to middle and high floors in the epidemic area, and water containers should be well managed.

摘要: 目的 研究白纹伊蚊在多层住宅居民区不同楼层的分布特征,以及在居民家庭和公共外环境之间的分布差异,为制定防制措施提供科学依据。方法 2020年5-10月采用布雷图指数(BI)法在江苏省南京、南通、苏州、无锡、徐州和盐城市同步开展居民区白纹伊蚊监测,应用SPSS 15.0软件比较居民区不同楼层、居民家庭和公共外环境之间的蚊密度差异,BI的比较采用Mann-Whitney U秩和检验或Kruskal-Wallis H秩和检验,白纹伊蚊阳性孳生率的比较采用χ2检验。结果 居民家庭中,积水容器主要有水生植物花瓶、贮水容器、盆景托盘积水、闲置容器等,其中水生植物花瓶数量最多,而闲置容器孳生白纹伊蚊幼蚊的比例最高。居民家庭的BI和白纹伊蚊阳性孳生率分别为9.17、10.79%,其与楼层、有无露天场所密切相关。1层的BI、白纹伊蚊阳性孳生率分别是2~6层的6.39~21.48和4.03~11.01倍,2~6层之间的BI、白纹伊蚊阳性孳生率差异均无统计学意义(均P>0.05)。具有露天场所的家庭BI、白纹伊蚊阳性孳生率分别是无露天场所家庭的16.86和4.88倍。公共外环境积水容器主要有闲置容器、贮水容器、盆景托盘积水、绿化带垃圾/可存水废弃物等,其中闲置容器数量最多,而贮水容器孳生白纹伊蚊幼蚊的比例最高。公共外环境BI、白纹伊蚊阳性孳生率为46.22和26.01%,分别是居民家庭的5.04和2.41倍。结论 江苏省多层住宅居民区白纹伊蚊主要孳生于公共外环境和1层居民(有露天场所)家庭,发生登革热疫情时,在对公共外环境和1层居民(有露天场所)家庭实施防控措施的同时,也要考虑疫区范围内中、高楼层的白纹伊蚊传播风险,做好积水容器管理等。
