There are a few different types of caterpillars that may be found on an apple tree. They range from budworms (helicoerpa), inch worms (loopers) and may also be the larvae of a variety of pests like the Codling Moth, Lightbrown Apple Moth, Oriental Fruit Moth or Fruit Fly.
Plant Part: The moths lay their eggs on the underside of leaves. The larvae of caterpillars hatch from the eggs and then feed on the leaves or fruit.
Symptoms: Holes are seen in the leaves or fruit of the apple tree. You may also notice black or brown droppings.
Control: Until you know which larvae is attacking your multi-grafted apple fruit salad tree you can start to remove these caterpillars by trying a variety of sprays like Dipel, Eco-oil or Success Ultra. Always follow the application instructions.
Prevention: Remove any loose bark or branches from the tree. Keep the area around your apple tree clean and your mulch about 2 inches away from the trunk. Attract beneficial insects to your card to pick off these critters.
