Description

Within sub-Saharan Africa: For countries in sub-Saharan Africa a statistical model of relative abundance of major vectors has been produced by Sinka et al. For these countries we extract the relative abundance of arabiensis, funestus and gambiae using the malaria atlas project “Anopheles arabiensis Patton, 1905”, “Anopheles funestus” and “Anopheles gambiae Giles, 1902” rasters. Proportions are normalised to sum to one (as other species may be present in the data).

Outside of sub-Saharan Africa: For countries outside of sub-Saharan Africa we do not have estimates of the relative abundance of vector species. There are however probability of occurrence maps for a large number of species Sinka et al. For these locations we select up to a maximum of three species ranked by their average probability of occurrence across a site. Each species is then given an equally weighted relative abundance.

The bionomics parameters for vectors in sub-Saharan Africa are parameterised using the fitted parameters in malariasimulation. All other vectors are parameterised from an (unpublished) literature review by Arran Hamlet. Any unknown species are assigned the median vector bionomics parameters across other species at the site. Please contact Pete Winskill directly if using these estimates.

The blood_meal_rates, foraging_time and mum parameters are assumed fixed at previously fitted values.

For each site we include an estimated level of pyrethroid insecticide resistance. This has been estimated by Tom Churcher and colleagues using spatio-temporally distributed bioassay mortality data.
