Figure 3 19 18 17 16 15 Female mosquitoes Uninfected Infected survival after egg laying (days) Fecundity and longevity were measured in the same individual female mosquitoes to see if there was a relationship between the two variables. The lines of best fit for mosquito survival against the number of eggs each female laid were plotted for uninfected females and infected females. This data is shown in Figure 4.
