Figure 1

Schematic map of the collection sites in Burkina Faso. For each of the two sites (Vallèe du Kou and Soumousso), the total number of mosquitoes collected is indicated. The relative percentage of species is reported in the pie charts for both larval and adult samples, and species are color-coded as described in the figure. Anopheles arabiensis were not studied further. The map and the drawings have been generated using Illustrator CC 2017 (Adobe).
