Codling Moth

Abstract

The codling moth (CM) is a pest introduced from Eurasia. The larvae feed on the fruit of a wide range of host plants including apple, pear, quince, hawthorne, crabapple, and walnut. CM completes 1.5-3.5 generations annually, depending on locality and length of growing season. It is the major fruit-feeding pest in fruit growing regions of the western United States. It is also a significant pest in the East, but has generally been managed by sprays used to control plum curculio and apple maggot. However, with the advent of trapping-based sprays for apple maggot, and a potential decrease in cover sprays, growers may begin to see more CM damage.
