Net reproductive rate (Ro), intrinsic rate of increase (r (d−1)), finite rate of increase (λ (d−1)), and mean generation time (T (d)) of S. frugiperda fed on five host plants.

|---|---|---|---|---|
| Ro | r (d−1) | λ (d−1) | T (d) | |

Population parameters Ro, r (d−1), λ (d−1) and T (d) were analyzed using age-stage, two-sex life table. Mean values M ± SE in the same column followed by different letters were significantly different (p < 0.05) (paired bootstrap test).
