Abstract: Root herbivore is of the main one that harms plant. The interrelations between root herbivore and plant have attracted extensive attention from scientists. In this paper, the effects of root herbivore on root biomass change, root regeneration and survival, plant physiology, dynamics of plant population, and plant structure, as well as the action mechanisms between plant semiochemicals and other organisms, were discussed, and some research fields that should be further strengthened, e.g., countermeasures of plant for esisting root herbivore, action mechanisms of root herbivore in changing ecosystem C and N cycling, and dynamic changes of ecosystem nutrients when parasitic nematodes exist, were suggested.
