Fig 2. Spatial distribution of two vector species governs magnitude and seasonality of malaria transmission over the Lake Kariba region.

(A) Adult vector numbers are tuned by scaling larval habitat availability of An. arabiensis and An. funestus vectors. Relative scales of the two vector species govern the seasonality of human biting. Shown: arabiensis scale = 100, funestus scale = 30. (B) Best fit arabiensis and funestus larval habitat availabilities vary spatially over the study region, with more habitat available for both species in the lower-altitude regions closer to the lake front.
