Average condition for Nonpersistence of a Delayed Discrete Ratio-Dependent Predator-Prey System

摘要：

Verifiable criteria are established for the nonpersistence for a delayed discrete periodic predatorprey model with Holling type II functional response. Our investigation shows that the average condition is a sufficient condition for the nonpersistence of the system, this also illuminates that if we study periodic system and its average system (defined in this paper) simultaneously, we can get more recipient results.
