A stage-structured predator-prey system (stage structure for both predator and prey) with discrete delay is studied in this paper. By introducing anew lemma and applying the standard comparison theorem, a set of novel criteria which ensure the permanence of the system is obtained. Our result supplements the main results of Chen, Xie and Li [Partial survival and extinction of a delayed predator-prey model with stage structure, Applied Mathematics and Computation, 219 (8)(2012) 4157-4162].
