摘　　要：【目的】分析上海市嘉定区白纹伊蚊的季节消长趋势和种群分布,为登革热等伊蚊传播疾病的防控提供科学依据。【方法】采用诱蚊诱卵指数(MOI)法对2020年嘉定区白纹伊蚊密度持续监测,分析不同月份、不同监测点及不同生境的白纹伊蚊分布差异,采用χ^(2)检验进行统计学分析。【结果】嘉定区2020年的监测数据显示,年均MOI为4.10,未超过安全阈值。季节消长呈现单峰分布,高峰出现在7月。城区消长趋势与总体相同,而非城区呈现双峰分布,高峰出现在6月和8月。不同监测点的白纹伊蚊密度相差较大,安亭监测点密度最高,达到6.64;华亭监测点密度最低,为2.09。不同生境白纹伊蚊分布差异较大,废品收购站、工地密度较高,高峰季节废品收购站MOI高达33.33。居民区白纹伊蚊密度显著高于非居民区(χ^(2)=6.082,P=0.014)。【结论】嘉定区白纹伊蚊广泛分布,5—9月均存在伊蚊密度超过安全阈值的区域,应对废品收购站、工地和居民区不同生境采取更有针对性的控蚊措施。[Objective]To determine the seasonal fluctuation and population distribution of Aedes albopictus in Jiading District,and provide scientific evidence for the prevention and control of dengue fever and other Aedes-borne diseases.[Methods]In 2020,the mosq-ovitrap method and mosq-ovitrap index(MOI)were used to monitor and evaluate the density of Aedes albopictus in Jiading District. Spatial and temporal distribution of Aedes albopictus was determined. Chi-square test was used for statistical analysis.[Results]In 2020,the annual average MOI was determined to be 4.10,which was under safety threshold. The seasonal fluctuations showed a unimodal distribution,which peaked in July. The fluctuation trend in urban area was similar to the overall trend,while that in the non-urban area showed a bimodal distribution with peaks in June and August. The density of Aedes albopictus at different monitoring sites varied widely,with the highest MOI(6.64)at Anting town and the lowest MOI(2.09)at Huating town. The distribution of Aedes albopictus in different habitats also varied widely;the highest density was observed in environments as waste collection stations and construction sites,with the highest MOI 33.33 in waste collection stations in peak season. The MOI value of Aedes albopictus in residential areas was significantly higher than that in non-residential areas(χ^(2)= 6.082,P = 0.014).[Conclusion]Aedes albopictus is quite common in Jiading District. In certain areas,Aedes density may exceed the safety threshold from May to September. More targeted mosquito control measures should be implemented in waste collection stations,construction sites and residential areas.
