| 摘 要： | 在云南省西南边境９县市捕获伊蚊属雌性成蚊１６种１９３６７只，用细胞法和乳鼠法分离病毒。从１８５批６４９１只白纹伊蚊中分离到病毒２株，从５０批１６０５只剌扰伊蚊中分离到病毒２株，从２３批７７２只窄翅伊蚊中分离到病毒２株，从４批１０３只阿萨姆伊蚊中分离到病毒１株。其它１２种共１０３９６只伊蚊的病毒分离物为阴性。分离到的７株病毒经免疫荧光、酶免疫、血凝抑制和中和试验鉴定，均为乙型脑炎病毒（ＪＥｖｉｒｕｓ）。白纹伊蚊是野外竹林的优势蚊种。分析认为白纹伊蚊在当地乙型脑炎病毒保存和传播中起重要作用，刺扰伊蚊、窄翅伊蚊和阿萨姆伊蚊亦可参与该病毒的传播。

| Abstract: | A total of 19 367 adult female mosquitoes belonging to 16 species of Aedes genus were captured from nine countries, south western part of Yunnan Province, China, and were examined by C6/36 cell method and suckling mouse method. Two strains of Japanese encephalitis (JE) virus were isolated from 6491 (185 pools) Aedes albopictus , two strains of JE virus were isolated from 1605 (50 pools) Ae. vexans, two strains of JE virus were isolated from 772 (23 pools) Ae. lineatopennis, and a strain of JE virus was isolated from 103 (4 pools) Ae. assamensis. Isolation of JE virus was negative to other 12 species of Aedes mosquitoes. Ae. albopictus was the superior species of mosquitoes in bamboo forest. These results indicated that Ae. albopictus from Yunnan has a potential role in the maintenance and transmission of JE virus in nature. Ae. vexans, Ae. lineatopennis and Ae. assamensis are also considered to be transmitting vector of JE virus in Yunnan. |
