摘要
基于杀虫剂对害虫的作用效果会随时间而减弱,本文将杀虫剂的作用函数和具有生育脉,中的害虫阶段结构模型相结合,建立一个更具有实际生物意义的害虫治理模型.通过对此模型的动力学性质分析,给出了模型的平凡周期解和正周期解的局部渐近稳定的的临界条件.
Considering that the pesticide effect on pests will weaken over time.In this paper,we combine the pesticide effect function with the pest stage-structured population model with birth pulse to establish a pest control model with more practical biological significance.By the analysis of the dynamical behavior of model,we give the threshold condition for the locally asymptotical stablility of the trivial periodic solution and the positive periodic solution.
