Population parameters of Ae. albopictus after treatment with Beauveria bassiana.
| Parameters | Control | LC20 Treated | LC50 Treated |
|---|---|---|---|
| Means ± SE | Means ± SE | Means ± SE | |
| Intrinsic rate of increase (r) | 0.2744 ± 0.007 a | 0.2506 ± 0.002 b | 0.2295 ± 0.005 c |
| Net reproduction rate (Ro) | 133.0 ± 16.21 a | 89.16 ± 9.31 b | 50.62 ± 8.31 c |
| Mean length of a generation (T) | 17.83 ± 0.12 a | 17.80 ± 0.16 a | 17.09 ± 0.09 c |
| Finite rate of increase (λ) | 1.316 ± 0.01 a | 1.285 ± 0.02 b | 1.258 ± 0.06 c |
| Birth rate (at SASD) | 0.319 ± 0.12 a | 0.2883 ± 0.21 b | 0.264 ± 0.21 c |
| Survival rate (at SASD) | 0.997 ± 0.02 a | 0.997 ± 0.03 a | 0.995 ± 0.01 b |
| Death rate (at SASD) | 3.206 ± 1.03 c | 3.491 ± 1.04 b | 5.499 ± 1.07 a |
r = Intrinsic rate of increase (per days); Ro = Net reproduction rate (offspring/individual); T = Mean length of a generation (days); λ= Finite rate of increase (per days); SASD = Stable age-stage distribution. Means in the same row, followed by the same letter are not significantly different (p > 0.05).
