摘　　要：目的调查山西省流行性乙型脑炎(乙脑)高发区蚊虫密度与种群构成。方法使用诱蚊灯在猪圈、湖渠等生境采集蚊虫。结果永济市伍姓湖蚊虫密度最高为2000.0只/灯,永济市城北蚊虫密度为1352.0只/灯,定襄县、永济市涑水河畔>500只/灯,临猗县(2006年9月、2007年8月)、五台县、太原市、长治市、芮城县圣天湖、阳泉市蚊虫密度>100只/灯;芮城、临猗县(2006年8月)、临猗县涑水河畔<100只/灯(湖渠生境文字标出,猪圈略)。在畜圈采集的蚊虫中,三带喙库蚊在临猗县(2007年8月)所占比例最高达77.7%,其次为芮城、临猗县(2006年9月)、永济市等;淡色库蚊在太原市城郊所占比例最高达100%,其次为五台、定襄县等;其他地区蚊种较少,所占比例较大的有背点伊蚊和刺扰伊蚊。在湖渠采集的蚊虫中,三带喙库蚊以芮城县圣天湖最高为94.4%;淡色库蚊以永济市伍姓湖及涑水河畔最高,达99.0%以上。结论畜圈及水源丰富的地区蚊虫消杀工作亟待加强,芮城县圣天湖景区应加强防蚊知识宣传和防蚊设施建设。Objective To investigate the density of mosquitoes and their population composition in the ares of Shanxi province where Japanese encephalitis （JE） was highly prevalent. Methods Mosquitoes were collected by light trap in pig pens, lakesides and other enviranments. Results It was found that the mosquito density at Wuxing lakeside in Yongji was 2000.0 each trap night, 1352.0 in Chengbei district of Yongji city, more than 500 in Dingxiang county and in the Sushui riverside in Yongji and 100-500 in Linyi county（in Sep. 2006 and in Aug. 2007）, Wutai county, Taiyuan city, Changzhi city, the Shengtian lakeside in Ruieheng and Yangquan city, with a density of less than 100 in Ruicheng, Linyi county （in Aug. 2006） and the Sushui riverside in Linyi. Culex tritaeniorhynchus accounted for 77.7 percent of all the mosquitoes collected from pens for livestock in Linyi （in Aug. 2007）, however Ruicheng, Linyi county （ in Sep. 2006）, Yongji city see a lower percentage in terms of the species. In terms of the density of Cx. pipiens pallens in the sites where the samples were collected, the suburbs were ranked at the top of the list, accounting for 100 percent, followed by Wutai county and Dingxiang county. There were fewer species of mosquetoes in other sites, with Aedes vexans and Ae. dorsalis as the major species. As far as the samples collected from lakesides and riversides were concerned, Cx. tritaeniorhynchus was most heavily populated in Shengtian lakeside in Ruicheng, accouting for 94.4 percent, with Cx. pipiens pallens having a highest in Wuxing lakeside and Sushui riverside in Yongji, being over 99.0%. Conclusion In view of the high mosquito density, Mosquitoe control in pens for livestock and other water-rich areas should be strengthened. Antimosquito publicity and promotion of mosquito control infrastructure are to be reinforced in Shengtian Lake scenic spot.
