| Abstract: | A stage structured model with delay that competition occurs between the two adults of species is stud-ied. The permanence and the stability of the nonnegative equilibria are analyzed. Some sufficient conditions which guar-antee the permanence of the system and the stability of the boundary and positive equilibrium are Obtained respectively. |
