Nonpersistence in a Non-autonomous Ratio-Dependent Predator-Prey System with Delay

摘要：

The condition for the nonpersistence of a delayed periodic ratio-dependent predator-prey model is established. Here we use the average values on the periodic intervals instead of the extreme values. In addition, our investigation confirms that the periodic system and its average system have some similar properties.
