Damage (Codling moth)

Newly hatched larva (one per fruit) burrow through skin into the flesh and through to the core.

• The entry point is often at the calyx (smaller fruits) or on the cheek (larger fruits).

• The entry hole is prominent and red-ringed, characteristically blocked by dry frass.

• Cut open fruit to reveal cavity, frass and sometimes the larva.
• Damaged fruits often fall prematurely and are found on the ground under the tree.
