Many species of tortrix moth caterpillars feed on the foliage of fruit trees, but most are not regarded as important pests. Certain species do attack apples, pears, plums, and strawberries, feeding on the fruit and causing economic damage where they occur. Apples are the most suscceptible crop as they can be attacked by caterpillars of the fruit tree tortrix moth.
In its native geographic range, the fruit tree tortrix moth is a regular pest of many fruit and nut crops, in many regions, and damage to apples especially is often quite serious. Larvae feed on the leaves, and also eat deep cavities into apple. Some larvae can be carried into commercial grocers where damage continues.
The fruit tree tortrix moth is not known to occur in Indiana.
