摘要/Abstract

摘要： 目的分析武汉市2018－2021年媒介伊蚊生态学监测数据，为有效防控登革热提供科学依据。方法媒介伊蚊幼蚊和成蚊生态学监测分别采用布雷图指数（BI）法和双层叠帐法。采用Excel 2010软件进行数据整理，SPSS 20.0软件进行统计。通过χ²检验分析不同时间BI的差异，通过方差分析或Kruskal-Wallis检验分析不同时间、生境间帐诱指数的差异，并评估登革热传播风险。结果 2018－2021年平均BI为4.50，帐诱指数为2.44只/（顶·h）。伊蚊密度指数均在2019年降至最低水平，2020－2021年呈现上升趋势，且居民区的帐诱指数高于旧轮胎堆放地（H=29.468，P<0.001）。不同年份的季节消长不完全一致，BI峰值出现在6－8月，帐诱指数峰值出现在7－8月。2018－2021年中有64.52%（20/31）的监测月份存在登革热传播风险，2021年7－8月的BI值达到登革热暴发的风险阈值。结论武汉市媒介伊蚊密度消长趋势呈上升态势，登革热传播风险有所上升，应加强和改进媒介伊蚊控制措施。

Abstract: Objective To analyze the ecological monitoring data of Aedes vector in Wuhan, China, 2018-2021, and to provide a scientific basis for effective prevention and control of dengue fever. Methods The Breteau index (BI) and double layered mosquito net methods were used for ecological monitoring of Aedes larvae and adults, respectively. All data were collected by Excel 2010 and statistically analyzed by SPSS 20.0 software. Differences in BI at different time points were analyzed by Chi-square test, and differences in net trap index between different habitats at different time points by analysis of variance or Kruskal-Wallis test; the risk of dengue fever transmission was assessed. Results In 2018-2021, the mean BI was 4.50, and the net trap index was 2.44 mosquitoes/net·h. The density index of Aedes fell to the lowest level in 2019 and showed an upward trend in 2020-2021. Meanwhile, the net trap index in residential areas was higher than that in waste tire stacking sites (H=29.468, P<0.001). The seasonal fluctuation was not completely consistent in different years; the peak BI value was observed from June to August, and the peak net trap index was observed in July and August. In 2018-2021, 64.52% (20/31) of the monitored months presented a risk of dengue fever transmission, and the BI value reached the risk threshold of dengue fever outbreak in July and August in 2021. Conclusion The fluctuation trend of vector Aedes mosquito density is on the rise in Wuhan, and the risk of dengue fever transmission has increased. Aedes vector control measures should be strengthened and improved.
