Abstract: The global behavior of positive solutions to a predator-prey diffusive system with stage-structure under homogeneous Neumann boundary conditions is proved, and stability of the non-negative equilibrium points to system is investigated with the assistance of the spectrum analysis and Lyapunov function.

Key words: cubic predator-prey system, stage-structure, reaction-diffusion, asymptotic stability
