Oriental fruit moths are important insect pests of peach, especially in the eastern United States. This insect is present only in the southern one-third of Iowa. The winter is passed as fully grown larvae underneath the bark of ground debris. The first generation larvae burrow in the twigs causing them to die back.
Subsequent generations attack fruit much like the codling moth.
They may enter the fuit through the stem or next to the stem. Infested peaches may look perfect at the time of picking but break down shortly after packing. There are several generations each year in Iowa.
