Abstract

Abstract: Objective To investigate the species composition and spatial distribution of mosquitoes in the human habitats of the Yellow River basin in Qinghai province, China.Methods Ten counties/cities/districts in the Yellow River basin in Qinghai province were set as the study space. From July to September of 2018 to 2021, blood-sucking mosquitoes active at night were collected using mosquito trap lamps (Gongfu Xiaoshuai) around rural livestock pens and residential houses, followed by identification and classification. Excel 2016 was used to establish the database to calculate population dominance and niche breadth. SPSS 22.0 was used to perform hierarchical cluster analysis on the correlation coefficients between mosquito species.Results A total of 2 684 mosquitoes belonging to 12 species of 4 genera were captured,among which Aedes vexans was the dominant species with species abundance of 30.030. The species abundance of Aedes vexans, Ae. falvidorsalis, Culex pipiens pallens, and Cx. modestus is more than 10.000; The ecological breadth of Ae. detrituss, Ae. dorsalis, Ae. vexans, and Cx. pipiens pallens is more than 6; Geographic niche width of Ae. dorsalis, Cx. modestus, Anopheles sinensis, and Ae. flavescens is greater than or equal to 1.000. There were niche overlaps among 90% of mosquito species, with 13 pairs >0.50 (including one pair with a complete overlap). Ae. sergievi was found in Guide county for the first time.Conclusions Ae. vexans, Ae. dorsalis, and Cx. pipiens pallens have relatively high numbers of species, species abundance, ecological amplitude, niche breadth, and niche overlap in human habitats in the Yellow River basin of Qinghai province. These mosquito species are widely distributed and highly competitive in the plateau. It is the first time to discover Ae. sergievi, a new record in Qinghai province, China.

摘要： 目的了解青海省黄河流域地区,以人居环境为主的生境中蚊类物种组成及其主要空间分布特征。方法以青海省内黄河流域10个县（市、区）为研究空间范围,于2018－2021年每年的7－9月,在农村畜圈及人居住房周边采用功夫小帅诱蚊灯对夜间活动的吸血蚊虫进行采样、分类鉴定,并利用Excel 2016软件建立数据库,计算种群优势度、生态位宽度等；使用SPSS 22.0软件对蚊虫种间的相关系数进行系统聚类分析。结果共捕获蚊类4属12种2 684只,其中刺扰伊蚊的物种多度为30.030,在数量上为优势种；刺扰伊蚊、背点伊蚊、淡色库蚊和凶小库蚊的物种多度>10.000,屑皮伊蚊、背点伊蚊、刺扰伊蚊、淡色库蚊的生态幅宽度>6,背点伊蚊、凶小库蚊、中华按蚊、黄色伊蚊地理生态位宽度≥1.000；近90%的蚊种之间都能产生生态位重叠,>0.50的重叠对数为13对（其中包括1对完全重叠）。在贵德县采样时首次发现短柄伊蚊。结论刺扰伊蚊、背点伊蚊和淡色库蚊在青海省黄河流域人居环境蚊类物种分布的数量、生态幅宽度、物种多度、地理生态位宽度及生态位重叠均较高,这些蚊种在高原地区有较高的空间分布和物种竞争能力；调查首次在青海省发现短柄伊蚊,属于青海省新记录。
