Abstract:
Objective To investigate the distribution of Aedes aegypti in Mangshi to inform dengue fever control. Methods Aedes adult mosquitoes were captured by human-landing catches around villages at both designated and random locations in the daytime to identify the composition and distribution of local mosquito species. Aedes larvae were collected in various types of water container inside and outside residential areas to calculate the mosquito larvae container positive index (CI), breteau index (BI), house index (HI) and thousand-person index. Results In designated villages, 38 adult mosquitoes from four species were captured, including 18 Ae. albopictus (47.37%); seven Aedes larva-positive water containers were found from 408 water containers, and the larval CI, BI, HI and thousand-person index were 1.72, 0.92, 1.23, and 12.26, respectively. In random locations, 4132 adult mosquitoes were collected, including seven Ae. aegypti (0.17%) and 2614 Ae. albopictus (63.23%); 170 water containers were investigated outside the villages, in which 20 water containers were positive with a larva-positive container index of 11.76. Nine positive containers were found from 152 water containers in 31 households, and the larva-positive CI, BI, HI and thousand- person index were 5.92, 6.12, 22.58, and 60.80, respectively. Conclusion Ae. aegypti were found in Mangshi for the first time. Ae. albopictus was widely distributed and locally predominant. Thus, the competent authority shall strengthen vector monitoring for aggressive dengue fever control.

摘要:
目的 了解埃及伊蚊在芒市的分布,为登革热媒介控制提供科学依据。方法 采用人工诱捕法对定点或不定点村寨进行成蚊采集,以了解当地白天成蚊种类组成及分布情况;对村内外的各类积水容器进行蚊幼虫采集,以观察当地蚊幼虫阳性容器指数、布雷图指数、房屋指数、千人指数情况。结果 在定点村寨,共捕获成蚊4种38只,其中白纹伊蚊18只(47.37%);检查各类积水容器408个,伊蚊幼虫阳性积水容器7个,阳性容器指数为1.72,布雷图指数0.92,房屋指数1.23,千人指数12.26;在不定点村寨,共捕获成蚊4132只,其中埃及伊蚊7只(0.17%),白纹伊蚊2614只(63.26%);野外竹林调查各类幼虫积水容器170个,其中阳性容器20个,阳性容器指数11.76;居民点共调查31户,幼虫各类积水容器152个,其中阳性积水容器9个,阳性容器指数5.92,布雷图指数6.12,房屋指数22.58,千人指数60.80。结论 首次在芒市发现埃及伊蚊分布,白纹伊蚊分布较广并属于当地的优势蚊种,建议有关部门加强登革热疫情及其媒介监测工作。
