摘要: 目的 了解腾冲市登革热传播媒介伊蚊分布情况,为登革热防控提供依据。方法 2014-2017年采用布雷图指数(BI)和容器指数(CI)法调查腾冲市媒介伊蚊幼蚊种类、密度,利用Excel 2007软件进行描述性分析。结果 共调查积水容器21 824个,伊蚊幼蚊阳性容器299个,以废旧轮胎阳性率最高,CI为2.17%(263/12 135),仅发现白纹伊蚊。1-4月和12月BI均为0,5月开始发现伊蚊幼蚊,8-10月达到高峰,BI最高为23.20,之后逐渐降低。结论 腾冲市白纹伊蚊6-10月密度较高,提示当地卫生部门应加强媒介伊蚊的监测,以防止输入性登革热病例引起本地病例发生。

Abstract: Objective To investigate the Aedes mosquitoes in Tengchong, Yunnan province, China, and to provide evidence for the prevention and control of dengue fever. Methods Breteau index (BI) and container index (CI) were used to monitor the species and density of Aedes larvae in Tengchong from 2014 to 2017. Excel 2007 software was applied for descriptive statistical analysis. Results A total of 21 824 water containers were screened, and 299 out of them were positive for Aedes larvae. The highest positive rate was observed in the used tyre, with a CI of 2.17%(263/12 135). Only Ae. albopictus larvae were found in this study. From 2014 to 2017, the BI was null from January to April and December, the young Aedes mosquitoes were found from May, then reached a peak from August to October (BI was 23.20), and gradually decreased after October. Conclusion The density of Ae. albopictus in Tengchong from June to October is relatively high, suggesting that the local health authorities should strengthen the surveillance on Aedes mosquitoes to prevent local dengue occurrence caused by imported dengue cases.
