Abstract: In this paper, a single-species model with distributed time delay in which
individuals exhibit three life stages is considered. Sufficient conditions
are obtained for the permanence of the system. Moreover, by using Lyapunov function, some conditions for global asymptotic stability of the system are investigated. An example satisfying the conditions of the main resuilts is given.

Key words: Permanence, Global asymptotic stability, Stage structure, Time delay
