The biting midge Kieffer, 1918 is a European widespread vector of avian malaria throughout the continent and is a possible vector of Akabane virus and Bluetongue virus. This species populates a wide range of environments in contrasting ecological settings often exposed to strong seasonal fluctuations. The main goals of this study were to investigate phenotypic variation at three departments in France (Corsica Island, Moselle and Var) and to determine if its phenotypes vary with the environment. wing phenotypes were analyzed using a geometric morphometric approach based on anatomical landmarks and outlines of the wing. Dendogram trees based on landmarks and the outlines-2 set (cell m4) showed similar topologies and separated populations of . In contrast, another set of outlines-1 (covering the r-m cross vein, M, radiale and arculus) presented a different hierarchical clustering tree. The phenotypic variation observed in indicated that these populations are exposed to environmental and ecological pressures. Our results suggest the presence of phenotypic plasticity in this species.
1918年的库蠓是欧洲大陆广泛传播禽疟的媒介，也是赤羽病毒和蓝舌病毒的可能媒介。该物种分布于各种生态环境中，这些环境往往受到强烈的季节性波动影响。本研究的主要目的是调查法国三个地区（科西嘉岛、摩泽尔和瓦尔）的表型变异，并确定其表型是否随环境而变化。使用基于翅膀解剖标志和轮廓的几何形态测量方法分析翅膀表型。基于标志和轮廓-2集（细胞m4）的树状图显示出相似的拓扑结构，并将……的种群分开。相比之下，另一组轮廓-1（覆盖r-m横脉、M、桡脉和关节）呈现出不同的层次聚类树。在……中观察到的表型变异表明这些种群受到环境和生态压力的影响。我们的结果表明该物种存在表型可塑性。
