The codling moth (Cydia pomonella) is one of the most well-known and feared pests in fruit growing . These small, inconspicuous moths prefer to lay their eggs on apple trees, occasionally also on pears, walnuts, or plums. Larvae (maggots) hatch from the eggs and bore directly into the fruit, leaving the typical feeding tunnels. Infected apples rot more quickly and are no longer storable.
