Global water quality changes posing threat of increasing infectious diseases, a case study on malaria vector Anopheles stephensi coping with the water pollutants using age-stage, two-sex life table method

Table 3 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; N_f,AL≥10, number of female adults with adult longevity ≥ 10 days; N_f,AL≥10/N, proportion of female adults in cohort with adult longevity ≥ 10 days

Parameters	Clean water	Moderately polluted	Highly polluted

λ (d⁻¹)	1.2927 ± 0.0085 a	1.2589 ± 0.0102 b	1.2564 ± 0.0098 b
R₀ (offspring/individual)	109.08 ± 14.33 a	65.35 ± 10.91 b	62.03 ± 9.47 b
T (d)	18.27 ± 0.24 a	18.16 ± 0.28 a	18.08 ± 0.23 a
N_f,AL≥10	45.00 ± 5.62 a	22.00 ± 4.14 b	27.00 ± 4.68 b
N_f,AL≥10/N	0.30 ± 0.0375 a	0.1467 ± 0.0288 b	0.18 ± 0.0312 b

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)
