摘要
Abstract
[Objective]Mathematically,the theoretical evidence of the controlling pests using the integrated pest management strategy in agriculture is given by the obtained results.[Methods]Considering the pesticide effect on natural enemies and the influence of the density restriction items,we improve a pest control model concerning integrated pest management (or IPM) to obtain a new equation to investigate the dynamical behavior.And the Matlab software is utilized to simulate numerically.[Results]We achieve the existence of first order periodic solution and prove the accuracy of the model.[Conclusion]According to the actual condition of the crop growth period in the specific field,we select the different initial value in the model to optimize the distribution of resources.关键词
