摘要: 目的 调查贵州省部分地区蚊虫种类及蚊媒病毒分布,为该地区蚊媒传染病防控提供依据。方法 用诱蚊灯采集蚊虫,将蚊虫分类鉴定后,用分子生物学方法检测蚊虫携带病毒种类,通过生物信息学软件构建毒株系统发育树。结果 2019年6月在贵州省黎平县中潮镇和乌当区羊昌镇共采集到蚊虫3属9种共27 169只,其中中华按蚊为优势蚊种,占捕获总数的50.47%(13 712/27 169);其次是三带喙库蚊,占45.80%(12 444/27 169);其他蚊虫最少,占0.26%(70/27 169)。从黎平县中潮镇的蚊虫标本LK6110中检出1株病毒,经分子生物学鉴定,该病毒株属于基因Ⅲ型流行性乙型脑炎病毒(JEV)。结论 本次贵州省调查地区的优势蚊种各不相同,羊昌镇以中华按蚊为主,中潮镇以三带喙库蚊为主,并在黎平县中潮镇三带喙库蚊中检出JEV Ⅲ型病毒。

Abstract: Objective To investigate the mosquito species and the distribution of mosquito-borne viruses in some regions of Guizhou province, China, and to provide a basis for the prevention and control of mosquito-borne diseases in this area. Methods Mosquitoes collected with trapping lamps were identified, mosquito-borne viruses were identified by molecular biological methods, and a phylogenetic tree of virus strains was constructed using bioinformatics software. Results A total of 27 169 mosquitoes (9 species, 3 genera) were collected in Zhongchao town of Liping county and Yangchang town of Wudang district (Guiyang city) of Guizhou province in June 2019. The dominant species was Anopheles sinensis (13 712/27 169,50.47%), followed by Culex tritaeniorhynchus (12 444/27 169,45.80%) and other species (70/27 169,0.26%). A virus strain isolated from a mosquito sample (LK6110) from Zhongchao town was identified as Japanese encephalitis virus genotype Ⅲ (JEV Ⅲ). Conclusion In this investigation, Yangchang town was dominated by An. sinensis and Zhongchao town was dominated by Cx. tritaeniorhynchus, and JEV Ⅲ was isolated from Cx. tritaeniorhynchus in Zhongchao town.
