†The mean macrogametocyte density ingested by the mosquitoes was estimated by multiplying the mean blood meal volume of membrane fed mosquitoes by the mean number of macrogametocytes per ml of blood as described by Okech et al. (2004).
*Represents the overall oocyst infection rates computed by the total number of positive mosquitoes divided by the total number of mosquitoes dissected.
The average of the mean oocyst count on infected mosquito midguts ± standard error of the mean (SEM).
