本文研究了影响单一作物的单一密度相关害虫的综合治理。该模型基本上是一个捕食者-捕食者模型，捕食者是害虫的天敌。此外，它还包含受影响作物的生长方程。这一动态模型以释放更多捕食者的形式接受生物防治，以喷洒杀虫剂的形式接受化学防治。为了考虑农药对生活在土壤水中的鱼类的自然副作用，对模型进行了进一步改进，以适应鱼类在土壤水中的生长方程。本文考虑了在喷洒农药和放生捕食者两个控制参数下模型的优化分析，这种多控制参数下的优化分析是一种全新的分析方法。
The paper deals with integrated pest management (IPM) of a single density-dependent pest affecting a single crop. The model is basically a prey–predator model, predator being the natural enemy of the pest. In addition, it also contains the growth equation of the affected crop. This dynamic model is subjected to biological control in the form of release of additional predators and chemical control in the form of spraying of pesticides. To consider the natural side effect of pesticide on fish living in the soil water, the model is further improved to accommodate the growth equation of the fishes in the soil water. The paper considers the optimal analysis of the model under two control parameters, one is the spraying of pesticide and other one is the release of predators; such optimal analysis under multi-control parameters is completely new of its kind.
