Pest Management Strategy with Eco-epidemiology Model

摘要

In this paper, we propose a stage-structure delay impulsive prey-predator model with infectious disease in the prey for pest management. We obtain the sufficient condition for the global attractivity of the susceptible mature pest-eradication periodic solution. We also observe the condition of which the susceptible mature pests and natural enemies (predator) can coexist, and the amount of susceptible mature pest will be less than the threshold of economic injury level. Therefore, our results provide a reliable tactic basis for the practical pest management.
