  1. GRR: Gross reproduction rate; R0: Net reproduction rate; r: The intrinsic rate of increase; λ: Finite rate of increase; T: Mean generation time. The standard errors were estimated using a bootstrap technique with 100,000 resampling. Different superscript letters within each generation (F1 or F2) indicate significant differences among treatments based on a paired bootstrap test at the 5% level.
