The invention belongs to the technical field of treatment of biological invasion malignant weeds, and particularly relates to a method for preventing and controlling invasion weeds solidago canadensisL. through the animal and plant synergy effect. The implementation method comprises the steps of putting of insects in the seedling stage, planting of cuscuta chinensis in the growing period, and secondary putting of insects in the growing period. Specifically, in the invasion area of the solidago canadensis L., larvae of argyrogramma albostriata bremeret grey are put, thus solidago canadensis L.leaves are eaten, and it is difficult for the leaves to carry out photosynthesis; cuscuta chinensis seeds are sowed in the later period, so that stalks of the solidago canadensis L. are killed, so that the nutrition transfer on the solidago canadensis L. is limited, the solidago canadensis L. is finally dead, and thus the ecological function is restored. The method is simple and high in operability, and has small interference with the ecology of the area, and the disadvantage is turned into the advantage. The multi-trophic-level co-evolution principle can be sufficiently utilized, the ecological chain of the argyrogramma albostriata bremeret grey, solidago canadensis L. and mantises is adopted, diffusion and spreading of the solidago canadensis L. can be effectively controlled, and the situation that the released argyrogramma albostriata bremeret grey is widespread and uncurbed can be avoided; the ecological balance is maintained.
