Damage (Fruit tree tortrix moth)

  • Larvae are leaf-rollers but damage to foliage is unimportant.
  • Damage to fruits occurs at different times during fruit development:
  • Overwintered larval feeding cavities in the receptacle of flowers and young fruitlets later heal to form corky scars characteristic of early caterpillar feeding on mature fruits.
  • Young caterpillars make small, shallow holes in the skin of fruits in July and August.
  • Larger caterpillars graze shallow irregular patches in the skin, especially at the point where fruits are in contact.
