Geographic Distribution of Chagas Disease Vectors in Brazil Based on Ecological Niche Modeling

Figure 2

Ecological niche models projected as potential distributions for triatomine species with widespread distribution in Brazil. (a) Panstrongylus geniculatus and (b) P. megistus. Known occurrences of the species are shown as yellow squares, and the final consensus prediction is shown as black shading. Areas identified as suitable based on climatic grounds only are shown in blue, whereas areas identified as suitable based on normalized difference vegetation index (NDVI) only are shown in green.
