【Abstract】 A pest management model with stage structure and time delay and impulsive control is investigated. Using the corresponding theories and methods of delayed differential equations and impulsive differential equations,sufficient conditions are obtained,which guarantee the global attractivity of the pest-eradication periodic solution and permanence of the system. Numerical simulations are carried out to illustrate the main results.更多还原
