目的了解新疆地区蚊虫种类、分布特点及虫媒病毒携带情况。方法使用灯诱法和挥网法捕捉蚊虫,分类鉴定后冷藏于液氮罐中,利用分子生物学方法检测蚊虫携带病毒情况。结果 2014年7-10月共捕获蚊虫3 550只,包括4属7种,其中尖音库蚊占捕获总数的54.28%;其次为里海伊蚊,占29.38%;其他种类占比较小。捕获蚊虫中均未检测到黄病毒属、甲病毒属、布尼亚病毒属、流行性乙型脑炎病毒、辽宁病毒、Tahyna病毒、蜱传脑炎及西尼罗病毒。结论新疆维吾尔自治区境内优势蚊种为尖音库蚊,未发现蚊类携带虫媒病毒,但仍需密切关注。
Objective To understand the species and distribution of mosquitoes in Xinjiang and the carrying status of arbovirus. Methods The mosquitoes were caught by light-induced method and swing-net method. After classification and identification, they were refrigerated in liquid nitrogen tank. Molecular biology was used to detect mosquito-borne virus. Results A total of 3 550 mosquitoes were detected in July-October 2014, including 4 genera and 7 species, of which Culex pipiens pallens accounted for 54.28% of the total number of catches, followed by Aedes albopictus, accounting for 29.38%. Other species accounted for a relatively small proportion. Flaviviruses, alphaviruses, Bunyaviruses, Japanese encephalitis virus, Liaoning virus, Tahyna virus, tick-borne encephalitis and West Nile virus were not detected in any mosquitoes captured. Conclusion The dominant mosquito species in Xinjiang Uygur Autonomous Region are Culex pipiens pallens mosquitoes, and no mosquito vectors were found. However, close attention should be paid.
