摘　　要：在研究了混合害虫模型的最优控制策略、关于常数和比例投放天敌的最优控制策略的基础上,又进一步讨论周期控制下的花费最小的控制策略,即周期投放天敌和周期综合控制策略.数值结果表明,最小花费上周期综合控制是最优的.In base of a hybrid model of the optimal pest control strategy and the optimal constant and proportion releasing of natural enemy, the author discusses the control strategy control in minimum cost, which is the periodic releasing natural enemy and periodic integrated numerical result indicates that the periodic integrated control strategy with of periodic impulse control strategy. The control strategy is the optimal for minimum cost.
