In contrast, each pest has several kinds, even dozens of species, hundreds of species of natural enemies in control of them, such as data show that there are more than 200 kinds of natural enemies of rice planthoppers and leafhoppers, which fully explains the abundance of natural enemy insect resources in nature.
