Fruit Worms
Cranberry and cherry fruitworms infest blueberry bushes, and feed on blueberries and shoots. Adult moths lay eggs on the bush. Once eggs hatch, tiny worm-like larvae infiltrate young berries and cause premature ripening. Inside the berry, the larvae mature into adult worms of about 3/5-inch in length. Depending on the specific type of worm, they can either be greenish-yellow, as the case of cherry fruit worms, or pinkish-red, like cranberry worms. Both types of worms, however, destroy blueberry crops in identical ways, and similar control applications are used to rid cranberry and cherry worms from berries.
