Codling moth

Codling moth

Cydia pomonella (L.)

Lepidoptera: Tortricidae


The adult's forewings are striped with fine brown-gray lines and a distinctive bronze to brown-black oval spot at the tip (A). Eggs are laid on the leaves or fruit. The pinkish larva has a black head and a brown thoracic shield (B).

  • Damage

    Attacks apple and pear mainly, although all deciduous tree fruits are susceptible. Larva produces reddish brown frass at the point of entry into the fruit—usually the calyx ("bottom") end (C)—and galleries in the flesh to the core of the fruit (D).

    Management

    Monitor the adults with pheromone traps and use a degree-day developmental model to time insecticide sprays; in the summer, broad-spectrum insecticides, kaolin clay, or selective viruses can be applied. Pheromone mating disruption has been of value in larger plantings (at least 5 acres).
