Effects of Imunit on the population parameters (Mean ± SE) of Spodoptera cilium offspring generation (F1).
| Parameters | Treatments | ||
|---|---|---|---|
| Control | LC30 | LC50 | |
| GRR (offspring/female) | 282.9 ± 52.75 a | 114.9 ± 55.65 b | 97.5 ± 51.41 b |
| R0 (offspring/female) | 203.9 ± 40.15 a | 9.190 ± 5.32 b | 3.900 ± 2.58 b |
| r (d−1) | 0.160 ± 0.01 a | 0.050 ± 0.02 b | 0.032 ± 0.01 c |
| λ (d−1) | 1.170 ± 0.01 a | 1.050 ± 0.02 b | 1.030 ± 0.01 b |
| T (d) | 33.87 ± 0.27 c | 38.78 ± 0.26 b | 42.00 ± 0.02 a |
Standard errors were estimated by using the bootstrap technique with 100,000 resampling. Means followed by the same letter within a row are not significantly different using the paired bootstrap test based on the confidence interval of difference (p < 0.05).
