The floodwater mosquito Aedes vexans can be a massive nuisance in the flood plain areas of mainland Europe, and is the vector of Tahyna virus and a potential vector of Dirofilaria immitis. This epidemiologically important species forms three subspecies worldwide, of which Aedes vexans arabiensis has a wide distribution in Europe and Africa. We quantified the genetic and phenotypic variation in Ae. vexans arabiensis in populations from Sweden (northern Europe), Hungary, and Serbia (central Europe). A landscape genetics approach (FST , STRUCTURE, BAPS, GENELAND) revealed significant differentiation between northern and southern populations. Similar to genetic data, wing geometric morphometrics revealed two different clusters, one made by Swedish populations, while another included Hungarian and Serbian populations. Moreover, integrated genetic and morphometric data from the spatial analysis suggested groupings of populations into three clusters, one of which was from Swedish and Hungarian populations. Data on spatial analysis regarding an intermediate status of the Hungarian population was supported by observed Isolation-by-Distance patterns. Furthermore, a low proportion of interpopulation vs intrapopulation variance revealed by AMOVA and low-to-moderate FST values on a broader geographical scale indicate a continuous between-population exchange of individuals, including considerable gene flow on the regional scale, are likely to be responsible for the maintenance of the observed population similarity in Aе. vexans. We discussed data considering population structure in the light of vector control strategies of the mosquito from public health importance.
洪水蚊伊蚊在欧洲大陆的洪泛区会造成极大困扰，它是塔希纳病毒的传播媒介，也是犬恶丝虫的潜在传播媒介。这种在流行病学上具有重要意义的物种在全球形成了三个亚种，其中阿拉伯伊蚊在欧洲和非洲分布广泛。我们对来自瑞典（北欧）、匈牙利和塞尔维亚（中欧）的阿拉伯伊蚊种群的遗传和表型变异进行了量化。一种景观遗传学方法（FST、STRUCTURE、BAPS、GENELAND）揭示了北部和南部种群之间存在显著差异。与遗传数据相似，翅几何形态测量学也揭示了两个不同的聚类，一个由瑞典种群组成，另一个包括匈牙利和塞尔维亚种群。此外，空间分析的综合遗传和形态测量数据表明，种群可分为三个聚类，其中一个来自瑞典和匈牙利种群。关于匈牙利种群中间状态的空间分析数据得到了观察到的距离隔离模式的支持。此外，方差分析显示种群间与种群内方差的比例较低，在更广泛的地理尺度上FST值低至中等，这表明个体在种群间持续交换，包括区域尺度上相当大的基因流动，可能是维持观察到阿拉伯伊蚊种群相似性的原因。我们根据这种蚊子对公共卫生的重要性，结合其种群结构的数据讨论了病媒控制策略。
