This paper deals with a Holling type III diffusive predator-prey model with stage
structure and nonlinear density restriction in the space 
. We first consider the asymptotical stability of equilibrium points for the model
of ODE type. Then, the existence and uniform boundedness of global solutions and stability
of the equilibrium points for the model of weakly coupled reaction-diffusion type
are discussed. Finally, the global existence and the convergence of solutions for
the model of cross-diffusion type are investigated when the space dimension is less
than 6.
