现代的农作物生产应以生物系统的管理为其特征。即使应该承认病害是不能消灭的,也应当通过使所出现的寄生物只能造成微小损害的方式来保持寄主/寄生物(包括害虫)系统的平衡。如果我们将野生植物/病原体系统(包括害虫)和原始作物系统与现代农业系统相比较,就可以得到有关寄主与寄生物的关系的一些有用的见识。在现代农业中,可以利用这些见识来管理寄主/寄生
Modern crop production should be characterized by the management of biological systems. Even though it should be admitted that the disease can not be eliminated, the balance of host / parasitic (including pest) systems should also be maintained in a manner that causes only minor damage to the parasites present. If we compare the wild plant / pathogen systems (including pests) and the original crop systems with modern agricultural systems, we can get some useful insights into host-parasite relationships. In modern agriculture, these insights can be used to manage hosts / parasites
