Abstract

Abstract: Objective To investigate the density, seasonal variation, and distribution of the dengue vector Aedes in Anhui province of China, and to provide a basis for the prevention and control of dengue fever. Methods Breteau index (BI, from May to October in 2015-2019) and the double mosquito net method (from May to October in 2015) were used for the surveillance of the dengue vector Aedes in 16 cities of Anhui province, and to analyze the density and distribution of Aedes. Excel 2007 and SPSS 17.0 softwares were used for analysis, and the F test was used to analyze the difference in container index (CI) between different breeding sites. Results In 2015-2019, the BI of Ae. albopictus larvae ranged from 8.87 to 12.05, and the CI of Ae. albopictus larvae ranged from 7.21 to 9.17. The peak values of BI and CI were mainly observed in July to September. Idle containers were the most important breeding site, accounting for 47.97% of all breeding sites. There was a statistical difference in CI between different breeding sites (F=27.856, P=0.010). In May to October of 2015, the mean density of adult Ae. albopictus mosquitoes ranged from 0.67 to 5.87 mosquitoes/net∙hour, and the peak value was observed in July to August. Conclusion Ae. albopictus is widely distributed and has a relatively high density in Anhui province, and there is a high risk of the occurrence and prevalence of dengue fever. Therefore, integrated management should be strengthened to prevent mosquito infestation.

摘要： 目的了解安徽省登革热媒介伊蚊的密度、季节消长及分布，为登革热防治提供依据。方法 2015－2019年5－10月，采用布雷图指数（BI）法，2015年5－10月采用双层叠帐法，对全省16个市登革热媒介伊蚊进行监测，分析伊蚊的密度和分布。利用Excel 2007和SPSS 17.0软件进行分析，不同孳生地容器指数（CI）差异采用F检验。结果 2015－2019年白纹伊蚊幼蚊BI在8.87～12.05，CI在7.21～9.17。BI和CI峰值主要出现在7－9月。闲置容器是主要孳生地，占孳生地调查总数的47.97%。不同孳生地的CI差异有统计学意义（F=27.856，P=0.010）。2015年5－10月，白纹伊蚊成蚊密度在0.67～5.87只/（顶·h），峰值出现在7－8月。结论白纹伊蚊在安徽分布广泛且密度较高，登革热发生和流行的风险较高，建议加强综合治理，防止蚊虫孳生。
