Most of the overwintering adults are overwintering in the orchard, and a few migrate from outside the orchard to the orchard. The overwintering generation of adults can last until June, when most of them move out of the orchard and lay eggs on other plants, the generation of nymphs occurs. Eggs laid before the beginning of June may appear on the first generation of adults before August. The first generation of adult worms can quickly lay eggs, and the second generation of nymphs can appear. Eggs laid in early June can only be produced in one generation. Adults that appear after mid-August are overwintering adults. The average life span of overwintering adults is 301 days, and the longest is 349 days. Adults that occur in orchards or migrate out of orchards appear in orchards after mid-August, endangering later fruits.

The first generation of adult insects can lay eggs quickly, and the second generation of adult insects can appear. Eggs laid in early June can only be produced in a generation. The adult worms that appear after mid-August are winter ingenas. The average life expectancy of winter adult worms is 301 days, with a maximum of 349 days. Adult worms that occur in or migrate from the orchard after mid-August, endangering late-stage fruit.

Most of the overwintering adults live in the orchard, and a few move from the orchard to the orchard. The overwintering generation of adults can last until June. When most of them move out of the orchard and lay eggs on other plants, the generation of nymphs occurs. Eggs laid before the beginning of June may appear in the first generation of adults before August. The first generation of adults can lay eggs quickly, and the second generation of nymphs can appear. Eggs born in early June can only be produced in one generation. After the middle of August, the adult is overwintering. The average life span of overwintering adults is 301 days, the longest is 349 days. In the middle of August, the adults that occurred in or migrated from the orchard appeared in the orchard, endangering the later fruits.<br>
