Table 2
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.
