摘　　要：通过应用几何形态学方法对库蠓属的3种近似种(南山库蠓Culicoides lansangensis、长喙库蠓Culicoides longirostris、连斑库蠓Culicoides jacobsoni)进行翅型的差异性分析,从而实现准确鉴定。采用地标点法对3种雌性库蠓标记13个地标点,通过主成分分析(Principal component analysis, PCA)、薄板样条分析(Thin-plate spline, TPS)、典型变量分析(Canonical variate analysis, CVA)以及聚类分析法来分析3种库蠓的翅型的主要变化部位以及变化趋势。3种库蠓翅的形态差异都较为显著,翅的差异主要在径室区及中4室。几何形态学方法可以用于库蠓种间的分类,本研究中的翅主要变异区域为以后库蠓的分类提供更多的参考依据。The geometric morphometric method was applied for difference analysis of wing type of 3 similar species of biting midges(Culicoides lansangensis, Culicoides longirostris and Culicoides jacobsoni), thus making an accurate identification. With landmark point method, 13 landmarks were marked for the 3 species of female midges, and the main changing parts and trends of the wing shape were analyzed by principal component analysis(PCA), thin-plate splines(TPS), canonical variate analysis(CVA) and cluster analysis. Significant differences in wing shape existed among the 3 species, the differences situated mainly in the radial cell and cua1. Geometric morphology is a useful tool for identifying interspecific relationships within the Culicoides species.
