摘要
目的 :阐明白纹伊蚊分布特点 ,掌握其自然感染虫媒病毒情况。方法 :白天在居民点周围和野外竹林区捕蚊 ,用细胞法和乳鼠法分离病毒。结果 :采获成年雌性蚊虫 8属 45种 2 4885只 ,其中白纹伊蚊 76 2 2只 ,占30 .6 2 %。从该蚊中分离到登革 4型病毒 4株 ,登革 3型病毒 1株 ,流行性乙型脑炎病毒 2株 ,基孔肯雅病毒 2株 ,甲病毒 2株。结论 :白纹伊蚊在云南广泛分布 ,属竹林区优势蚊种 。
Objective: To study the characterized distribution of Aedes albopictus and it's natural infection of arboviruses in Yunnan province. Methods: Collecting mosquitoes from the outdoor bamboo forests in the daytime.Using C6/36 or BHK21 cells and suckling mice to isolate viruses. Result: 24 885 adult female mosquitoes belonging 45 species of 8 genera were captured.The component rate of Ae.albopictus was 30.62 %( 7 622 / 24 885 ). Four strains of dengue(DEN) type 4 virus,a strain of DEN type 3 virus,two strains of Japanese encephalitis(JE) virus,two strains of chikungunya(CHIK) virus and two strains of Alphavirus were isolated from Ae.albopictus . Conclusions: Ae.albopictus is widely distributed in Yunnan province,which belong to the dominant species of mosquitoes in bamboo forests. Ae.albopictus might be the main transmitting vector of DEN and CHIK viruses in Yunnan,while it is also considered to be transmitting vector of JE virus.
