Figure 4

Distribution of Amblyomma variegatum on the central high plateau of Madagascar according to tick collection and surveys carried out in 2008 and 2010. The grey areas in the small map represent the areas higher than 1000 m, and the dot the location of the capital city, Antananarivo. In both maps, the triangles represent the main summits. On the close-up map of the central high plateau, the plain and dash lines represent the main and secondary roads, respectively; the numbers in brackets, the altitude of some of the visited sites; the black dots, the villages where A. variegatum was collected or reported by the polled farmers; the white dots, the villages where the tick is absent; and the half black-half white dots, the villages where the polled farmers did not agree regarding the presence of the tick.
