Peach twig borer, Anarsia lineatella
Peach twig borer, Anarsia lineatella is a serious pest of stone fruits.
The main host crops are peach, apricot, nectarine, almond, plum and prune. Young larvae bore into buds and developing shoots causing them to wilt and die. When populations are high, spring larval feeding can cause substantial damage to trees. Larvae of the summer generations attack the fruit, usually making several entry holes near the stem end. Damaged fruit and twigs exude gum.
