Comparative analysis of invasive and native populations of Harmonia axyridis by a complex of morphological traits


Abstract: Elytral pattern, pronotum pattern, and presence/absence of the elytral ridge were compared for 4751 individuals of Harmonia axyridis (Coleoptera: Coccinellidae) collected from four invasive populations (Europe, USA) and six native populations (Russia). While the American population is similar to the native Far East populations and probably has a common origin from a limited number of individuals, the origin of the European invasive populations is likely to be mixed.
