这篇论文提出柔韧的组织阶段的 SI 有周期的经常的脉搏与病原体释放传染害虫的 eco 流行病学的模型。作者证明因此,为系统的周期的答案和永久性取决于的‘ p est-eradication' 的全球 attractivity 的条件预定延期作者叫它“无益”。进一步,在场的作者害虫人口在经济阀值水平(ETL ) 下面被放在的害虫管理策略当害虫人口是一致地坚持的时。由数字分析,作者也为传染害虫释放的易受影响的害虫和脉搏显示出那经常的成熟时间延期能在系统的动力学上带明显的效果。
This paper formulates a robust stage-structured SI eco-epidemiological model with periodic constant pulse releasing of infectious pests with pathogens. The authors show that the conditions for global attractivity of the 'pest-eradication' periodic solution and permanence of the system depend on time delay, hence, the authors call it "profitless". Further, the authors present a pest management strategy in which the pest population is kept under the economic threshold level (ETL) when the pest population is uniformly persistent. By numerical analysis, the authors also show that constant maturation time delay for the susceptible pests and pulse releasing of the infectious pests can bring obvious effects on the dynamics of system.
