Tufted apple bud moth - Platynota idaeusalis (Walker)
Home > Pest management > tufted apple bud moth
Larvae cut leaf petioles causing the leaf to hang down, and proceed to feed in the leaf encased in silken threads. Areas of fruit feeding are separated, not con-tinuous, and take on the appearance of tiny holes, shallow channels, or as an area of rot, generally around the stem. Larvae overwinter in the orchard, and can be found in the trees early in the spring; adults emerge the beginning of May, first generation larvae appear around mid-June, second generation larvae appear mid-late August.
