Abstract: Objective:To study the characterized distribution of Culex tritaeniorhynchus mosquitoes and their infection rate with Japanese encephalitis virus in Yunnan province.Methods:Collecting mosquitoes from the indoor and the stables of livestocks in villages.Using C6/36 cells and mice to isolate viruses.Results:70 167 adult female mosquitoes belonging to 35 species were captured.The component rate of C.tritaeniorhynchus was 29.16%( 20 464/70 167),its density peak was from July to September.Twenty strains of Japanese encephalitis(JE) virus were isolated from C.tritaeniorhynchus (321 pools;15 442 mosquitoes).The positive isolation rate 6.23%(per 100 pools),the minimal field infection rate 1∶772 or the mosquito body virus carrier rate 1.30‰(per 1 000 mosquitoes).Conclusions: C.tritaeniorhynchus was widely distributed over Yunnan province,which belong to the superior species of mosquitoes. C.tritaeniorhynchus might be the main transmitting vector of JE virus in Yunnan.
摘要: 目的:研究三带喙库蚊的分布特点及乙型脑炎病毒的感染率。方法:在农村畜圈和人房捕蚊,用C6/36细胞和小白鼠法分离病毒。结果:采获成年雌蚊35种70167只,其中三带喙库蚊20464只,构成比为29.16%,季节高峰是7~9月。从三带喙库蚊中分离出20株乙型脑炎病毒,批阳性率为6.23%,现场感染比1∶772,最低带病毒率1.30‰。结论:三带喙库蚊在云南广泛分布,属优势蚊种,是云南乙型脑炎的主要传播媒介。
