摘要: 目的:掌握蚊虫分布特点及其在虫媒病毒传播中的作用。方法:捕获蚊虫,分离病毒。结果:1981、1982、1986和1988年在景洪市采获成年雌性蚊虫31种22823只。白天在野外竹林采获蚊虫17种,优势蚊种为圆斑伊蚊、刺扰伊蚊和白纹伊蚊;夜间在农村畜圈及其周围采获蚊虫19种,优势蚊种为棕头库蚊、三带喙库蚊、迷走按蚊。从采获的7种蚊虫体内分离到流行性乙型脑炎病毒10株,基孔肯雅病毒3株,登革热病毒1株。其中从白纹伊蚊分离到3株病毒(2株基孔肯雅病毒、1株登革热病毒),从三带喙库蚊分离到5株病毒(4株流行性乙型脑炎病毒,1株基孔肯雅病毒)。结论:白纹伊蚊是当地基孔肯雅和登革热病毒的主要传播媒介,三带喙库蚊是流行性乙型脑炎病毒的主要传播媒介。

Abstract: In July-August 1981,1982,1986 and 1988, 22823 adult female mosquitoes belonging to 31 species were collected in Jing Hong city Yunnan province. During the day, the 17 species mosquitoes were collected in the hillside bamboo forest and the preponderance mosquito species were Aedes annandalei, Aedes vexans and Aedes albopictus. During the night the 19 species mosquitoes were collected in the animal house of village and nearby regions and the preponderance mosquito species were Culex fuscocephalus, Culex tritaeniorhynchus and Anopheles vagus. The 10 strains of Japanese B encephalitis virus, 3 strains of Chikungunya virus and 1 strain of Dengue virus had been isolated from 7 species mosquitoes. 2 strains of Chikungunya virus and 1 strain of Dengue virus were isolated from Aedes albopictus; 4 strains of Japanese B encephalitis virus and 1 strain of Chikungunya virus were isolated from Culex tritaeniorhynchus. These results indicated that Aedes albopictus were main vector transmitting Chikungunya virus, Dengue virus and Culex tritaeniorhynchus were main vector transmitting Japanese B encephalitis virus in Jing Hong city, Yunnan province.
