Kaplan-Meier survival curves of Anopheles gambiae Keele strain and selected lines from the black group. Lines represent the mean values from three populations of 25 females that were given either one infected bloodmeal, one uninfected bloodmeal, or no blood meal on day 0. All mosquitoes were maintained on sugar water, and mortality was assessed daily. Time to failure represents time to death in days. Probabilities of survival did not differ significantly between lines within an experimental treatment (no P-value was less than 0.05 for any group).
