From these, two pieces of experience were enlightened as follows: the first, the reforms of cropping systems and crop distributions must be beneficial to pest control or at least not increase the damage of crop pests; the second, we should further clarify the relationship between population dynamics of pests and cropping system/crop distribution, the basis for correctly laying down the ecological regulation systems.展开更多
