摘要
A periodic predator-prey model with stage structure for prey and time delays due to negative feedback and gestation of predator is proposed. By using Gaines and Mawhin's continuation theorem of coincidence degree theory, sufficient conditions are derived for the existence of positive periodic solutions to the proposed model. Numerical simulations are presented to illustrate the feasibility of our main result. © Springer-Verlag 2004.
