Mathematical Model for the Pest Biological Prevention

LIU Qiong (Department of Mathematics and Computer Science,Qinzhou University,Qinzhou Guangxi 535000 China)  
A stage structure predator-prey model with time delay and impulsive release on natural enemy is considered.The sufficient conditions for the global attractivity of pest-extinction periodic solution are obtained.Furthermore,it is obtained that the pest population can be controlled under the economic injury level E(Ell) if the impulsive period is within an appropriate range,Our results provided helpful for the practical pest management.
