摘　　要：:198 1、1982、1983、1986、1987和 1988年在西双版纳州景洪、勐海和勐腊县 (市 )捕获成年雌性蚊虫 8属 34种 34 5 0 8只。夜晚在农村畜圈及其周围采获蚊虫 2 1种 ,优势蚊种为棕头库蚊和三带喙库蚊 ;白天在野外竹林采获蚊虫 2 5种 ,优势蚊种为圆斑伊蚊和白纹伊蚊。从三带喙库蚊 (8株 )、霜背库蚊 (4株 )、伪杂鳞库蚊 (3株 )、环带库蚊 (1株 )、棕头库蚊 (1株 )、中华按蚊 (3株 )、刺扰伊蚊 (2株 )、白纹伊蚊 (1株 )、窄翅伊蚊 (1株 )和常型曼蚊 (1株 )中分离到乙型脑炎病毒 2 5株。从白纹伊蚊中分离到登革 4型病毒 3株 ,登革 3型病毒 1株 ,基孔肯雅病毒 2株。从三带喙库蚊中分离到基孔肯雅病毒 1株。分析认为 ,三带喙库蚊是当地乙型脑炎病毒的主要传播媒介 ,伪杂鳞库蚊和霜背库蚊亦是该病毒的重要传播媒介 ;From July to August in 1981,1982,1983,1986,1987 and 1988, 34 508 adult female mosquitoes belonging to 34 species of 8 genera were captured from Jinghong,Menghai and Mengla Counties in Xishuangbanna Prefecture of Yunnan Province,China.During the night,the 21 species mosquitoes were collected in the rural stable and nearby regions and the superior mosquito species were Culex fuscocephalus and C.tritaeniorhynchus.During the day,the 25 species mosquitoes were collected in the bamboo forest and the superior mosquito species were Aedes annandalei and Ae.albopictus.Mosquitoes captured were examined by C6/36 cell method and suckling mouse method.Twenty five strains of Japanese encephalitis(JE)virus were isolated from C.tritaeniorhynchus(8 strains),C.whitmorei(4 strains),C.pseudovishnui(3 strains),C.annulus(1 strain),C.fuscocephalus(1 strain),Anopheles sinensis(3 strains),Ae.vexans(2 strains),Ae.albopictus(1 strain),Ae.lineatopennis(1 strain) and Mansonia uniformis(1 strain).Three strains of dengue type 4 virus,a strain of dengue tyep 3 virus and two strains of Chikungunya(CHIK) virus were isolated from Ae.albopictus.A strain of CHIK virus was isolated from C.tritaeniorhynchus.These results indicated that C.tritaeniorhynchus was the main transmitting vector of JE virus in Xishuangbanna,while C.whitmorei and C.pseudovishnui were also important transmitting vectors of JE virus,and Ae.albopictus was the mainly transmitting vector of dengue and CHIK viruses in Xishuangbanna.
