Means (± SE) of population parameters of Anopheles stephensi reared in clean, moderately and highly polluted water: r, intrinsic rate of increase; λ, finite rate of increase; R0, net reproductive rate; T, mean generation time; Nf,AL≥10, number of female adults with adult longevity ≥ 10 days; Nf,AL≥10/N, proportion of female adults in cohort with adult longevity ≥ 10 days

Means in the same row followed by different letters are significantly different based on the confidence intervals of the differences between treatments using the paired bootstrap test (P < 0.05)
