Estimated vectorial capacity of Anopheles gambiae mosquitoes in forested and deforested areas, western Kenyan highland and lowland*

Site Land use type m a N P Vectorial capacity
Highland Forested 3.05 0.198 13.9 0.927 0.54
Highland Deforested 4.64 0.233 12.8 0.917 0.96
Lowland Deforested 7.85 0.465 11.7 0.923 8.30

*m, relative density of vectors in relation to humans; a, average no. children bitten by 1 mosquito in 1 day; n, duration of sporogony in days; P, proportion of vectors surviving per day. See text for details on data source and assumptions made for calculating each variable.
