根据我省农业生态的现状,现阶段的区域性生态控制农作物害虫应以种植结构的调整为基础,以发挥生态因素的控制害虫的作用为重点、充分发挥天敌、生物制剂的控害作用,必要时辅以化学防治调节,达到控害的目的,在进行害虫生态控制时,既要突出生态学观点,又要坚持经济学原则,使挽回损失和效益必须大于或等于害虫管理的费用,达到生态、经济、社会效益的共存。
According to the status quo of agro-ecology in our province, the pest of crop ecology at the present stage should be based on the adjustment of plantation structure, and take the role of controlling pests as ecological factors as the key points, giving full play to the controlling role of natural enemies and biological agents. When supplemented by chemical prevention and control to achieve the purpose of controlling pests, it is necessary to give prominence to ecological points of view while insisting on economic principles so that the losses and benefits should be greater than or equal to the pest management costs and reach the ecological level , Economic and social benefits of coexistence.
