The adult beetle feeds on many kinds of fruits in the “stone fruit” groups, including plum, peach, and cherry, as well as apples, peaches, and blueberries. It also feeds on the flowers and foliage. The feeding creates holes in the fruits that then encourage fungus to grow as well, destroying the fruit. The female cuts small holes in the fruit to deposit her eggs and the larvae then feed within the fruit as well. The adult stage overwinters in leaf litter and other debris on the ground.
Removing damaged and fallen fruit and disposing of it quickly will eliminate many larvae that may be within those fruits. Physically jarring the beetles from the trees can also cause many to be removed and disposed of. Insecticide applications can be timed with the emergence of the adult beetles in early spring, before they have deposited eggs into the new fruits.
