Note: R0, net reproductive rate; GRR, gross reproductive rate; r, intrinsic rate of increase; λ, finite rate of increase; T, mean generation time; , mean value; SE, standard error. Means followed by different letters in the same row are significantly different by using paired bootstrap test based on the CI of difference. Standard errors were estimated by using 1,000,000 bootstrap resampling
