摘　　要：1984年及1989年7～8月,在盈江县捕获成年雌性蚊虫7属32种632O只,霜背库蚊、三带喙库蚊和棕头库蚊是农村畜圈的主要蚊种,伪白纹伊蚊和白纹伊蚊是野外竹林区的优势蚊种。对所获蚊虫用C6/36细胞和小白鼠方法分离病毒,从三带喙库蚊和窄翅伊蚊中各分离到1株乙型脑炎病毒。分析认为三带喙库蚊是当地乙型脑淡病毒的主要传播媒介,窄翅伊蚊亦可参与该病毒的传播。In July - August 1984 and 1989,6320 adult female mosquitoes belonging 32 species of 7 genera were captured from Yingjiang county, Yunnan province, China. Culex whitmorei,C. tritaeniorhynchus and C. fuscocephalus were the main species of mosquitoes in the rural stable. Aedes pseudalbopictus and Ae. albopictus were the superior species of mosquitoes in bamboo forest. Mosquitoes collected were examined by C6/36 cell method and suckling mouse method. A strain of Japanese encephalitis(JE) virus was isolated from C. tri-taeniorhynchns(1160 mosquitoes ),a strain of JE virus was isolated from Ae. lineatopennis (80 mosquitoes). Isolation of virus was negative to other species of mosquitoes. These results indicated that C. tritaeniorhynchus might be the main transmitting vector of JE virus in Yingjiang,while Ae. lineatopennis is also considered to be transmitting vector of JE virus.
