Madeira Island map showing sampling sites: Pául do Mar, a fishing village in the western point of Ae. aegypti distribution in the island; Funchal, the capital, where the main harbour is present; Santa Cruz, near the only Airport of the island. Below each locality name is the year of the first report of the introduction of the species. Pie charts indicate proportions of individuals assigned (Tq = 0.50) to each of the three genetic clusters determined by STRUCTURE (See text). Grey colour indicate admixed individuals with no cluster assignment. The map was produced using ArcGIS 10.2 (Esri, Redlands, CA).
