Genetic structure of Aedes albopictus in Réunion Island. a A two-dimensional plot from a principal component analysis (PCA) based on individual genotypes for 10 microsatellite loci. b Bayesian analysis of population structure for the 19 mosquito populations produced using STRUCTURE. Each vertical bar represents an individual, each color represents a cluster (K) and the color of the bar indicates the probability of assignment to each cluster. Only the results for K = 2 to K = 4 are presented
