目的 掌握上海市松江区积水容器白纹伊蚊的越冬状况，并探究其主要影响因素，为白纹伊蚊越冬期的科学防控提供依据和建议。方法 2017年1－3月采用横断面抽样调查方法，随机采集上海市松江区11个街道（镇）居民小区底楼庭院周边积水容器中的积水，在人工气候箱中孵化2周，观察和记录是否有白纹伊蚊幼虫孵化及孵化时间，利用SPSS 16.0和Excel 2003软件进行统计分析；运用χ²检验和非参数检验进行单因素分析；采用二分类非条件Logistic回归和广义线性模型进行多因素分析。结果 白纹伊蚊越冬卵孵化阳性率达40.27%（60/149）。各街道（镇）潜在的布雷图指数均 > 20，最低为20.00，最高为66.67。城区白纹伊蚊阳性率高于非城区，差异有统计学意义（P=0.018）；暂时性积水容器和废弃轮胎中白纹伊蚊阳性率均高于固定性积水容器，差异均有统计学意义（P=0.001、0.049）；60份伊蚊孵化阳性积水中，最短孵化时间需0.75 d （18 h），最长达13.00 d，孵化时间中位数为6.00 d；随着月份的增加，孵化耗时逐渐降低，两者呈负相关（b=-1.252，P=0.046）。结论 松江区冬季积水容器中白纹伊蚊越冬卵孵化阳性率较高，暂时性积水容器和废弃轮胎是其主要越冬场所；1－3月白纹伊蚊孵化耗时逐月降低，故应在冬季后、早春前积极开展防控工作，从源头上降低和控制区域内次年的白纹伊蚊密度。

Objective To understand the overwintering status of Aedes albopictus and influencing factors in Songjiang district, for providing scientific suggestions for local Ae. albopictus control and prevention in winter season. Methods Cross-sectional study was applied, and water samples of containers were collected randomly in courtyard in 11 sub-districts in Songjiang from January to March in 2017. Then the collected water samples were incubated in artificial climate box for 2 weeks, and the hatching rate and incubation time were recorded, then a statistical analysis was conducted by applying SPSS 16.0 and Excel 2003 software. Chi square test and non-parametric test were used for univariate analysis, binary logistic regression and the generalized linear model analysis were applied for multivariate analysis. Results The overwintering positive rate of Ae. albopictus was 40.27% (60/149). The potential Breteau index (BI)of 11 sub-districts were all over 20, with the lowest of 20.00 and the highest of 66.67. Logistic regression analysis indicated that the positive rate of Ae. albopictus in urban areas was higher than that in rural areas (P=0.018), and the positive rate in temporary water containers and waste tires were higher than that in the fixed water containers (P=0.001, 0.049). Of all 60 water samples with positive incubation, the shortest incubation time was 0.75 d (18 h)and the longest incubation time was 13.00 d, with a median incubation time of 6.00 d. Generalized linear model analysis showed that the incubation time decreased gradually with the increase of months (b=-1.252, P=0.046). Conclusion The overwintering positive rate of Ae. albopictus in water containers in Songjiang district was high, and the temporary water containers and waste tires were the main overwintering places for Ae. albopictus, the incubation time decreased month by month from January to March. Therefore, we should carry out Ae. albopictus control and prevention in winter, this could reduce the density of the mosquito of the next year, which was a critical control and prevention measure for Ae. albopictus.
