Adult forewings are bluish gray with a central cream-colored band (A puparium is on the left) and black spots. The chocolate brown larva has a black head and thoracic shield (B).

  • Crops Affected: apples, cherries, pears

    Damage

    Apple, pear, and cherry are attacked. Larvae tunnel in fruit buds in the spring. During bloom, damaged leaves are tied together as a shelter. In August, larvae attack the fruit by digging tiny holes close together, which often appear in a discolored zone and are arranged in a triangle (C); they also feed on the lower surface of the leaves and on their parenchyma tissue.

    Management

    This insect causes little damage and tolerance is more economical than intervention. Economic infestations can be controlled by the use of selective (e.g., Bacillus thuringiensis) or broad-spectrum insecticides.
