摘要 为调查福建省人居环境中常见吸血库蠓的种群分布,2022年6月—2023年9月在福建省9个地市人居环境的不同生境(人房、田野、畜舍和民居附近的红树林)设置19个监测点,采用灯诱法进行蠓虫收集。收集到的蠓虫通过形态学和细胞色素C氧化酶亚基1 (cox1)基因鉴定判定蠓种。使用Microsoft Excel 2007软件建立数据库,使用SPSS 20.0软件进行统计学分析。气象条件与库蠓捕获数量之间的线性相关程度采用Pearson相关分析。共捕获库蠓7 862只,隶属于6亚属13种。其中经形态学鉴定有12种,1种库蠓经分子鉴定为环基库蠓。荒川库蠓分布最广,在19个监测点均被捕获。人房、田野、畜舍和红树林捕获的库蠓分别占捕获库蠓总数的7.10%(558/7 862)、12.79%(1 006/7 862)、30.44%(2 393/7 862)和49.67%(3 905/7 862)。人房、田野和畜舍的优势种是荒川库蠓,分别占该生境捕获库蠓总数的85.84%(479/558)、84.00%(845/1 006)和87.67%(2 098/2 393);红树林的优势种是环基库蠓,占该生境捕获库蠓总数的99.74%(3 895/3 905)。红树林每个月均可捕获环基库蠓,其中7月份捕获数量最多,占全年捕获总数的52.32%(2 038/3 895)。环基库蠓的捕获数量与月平均温度呈正相关(r=0.628,P <0.05),与平均风速和降雨量无相关性(r=-0.316、-0.073,均P> 0.05)。本研究结果显示,福建省人居环境中吸血库蠓的种类多、数量大,其中荒川库蠓分布最广,是人房、田野、畜舍生境的优势种;环基库蠓是红树林生境的优势种。 To investigate the population distribution of common Culicoides biting midges in human settlements in Fujian Province,19 surveillance sites were set up at different environment in the human settlements(human house,field,livestock houses and mangroves near houses) of 9 cities in Fujian Province from June,2022 to September,2023,and the midges were collected by light trap.The species of midges were identified by morphological classification and molecular identification of cylochrome C oxidase subunit 1(cox1) gene.The database was established by Microsoft Excel 2007 software and SPSS 26.0 software was used to perform the statistical analysis.The degree of linear correlation between meteorological conditions and the number of Culicoides was analyzed by Pearson correlation analysis.A total of 7 862 Culicoides were collected,which were identified as 13 species belonging to 6 subgenera.Twelve species were identified by morphological classification,and 1 species was identified as C.circumbasalis by molecular identification.C.arakawae had the broadest distribution,being caught in all 19 surveillance sites.The number of Culicoides caught in human house,field,livestock houses and mangroves accounted for 7.10%(558/7 862),12.79%(1 006/7 862),30.44%(2 393/7 862) and 49.67%(3 905/7 862) of the total,respectively.C.arakawae was the dominant species of human house(85.84%,479/558),field(84.00%,845/1 006) and livestock houses(87.67%,2 098/2 393),and C.circumbasalis was the dominant species of mangroves(99.74%,3 895/3 905).C.circumbasalis was consistently captured in the mangroves throughout the entire year,with a notable peak in July(52.32%,2 038/3 895).The number of catched C.circumbasalis showed a positive correlation with the average monthly temperature(r = 0.628,P < 0.05),butno correlation with mean wind speed or rainfall(r =-0.316,-0.073,both P > 0.05).The results of this investigation showed that the population of Culicoides in human settlements was diverse and abundant in Fujian Province.C.arakawae had the broadest distribution,being the dominant species of human house,field and livestock houses,and C.circumbasalis was the dominant species of mangroves.
