Second, the law of occurrence There are many generations in a year, and the wintering occurs in the cracks of the buds and branches of the winter buds. In the spring, when the leaves are spread, the mites migrate to the old leaves and lay eggs. After hatching, the nymphs invade into the leaves of the mites to form insects. Generally, the new shoots began to be damaged in the middle and late May, and it was the first hazard peak until mid-June. In mid-August, it was transferred to the autumn shoots, and it was the second hazard peak until September, and entered the dormant period in November.
