    Pest Profile

    • About the pest


      The codling moth is approx. 1 cm long, greyish with light grey striations and copper-colored spots at the tip of the wings (Picture 2). The wing span is 1.4 to 2.2 cm. Codling moth develops one generation per year under cool conditions. Flight activity is mainly in May and June. The female moths lay 30 to 60 eggs on the fruit or leaves of fruit trees (Picture 1). Eggs hatch and the young larvae migrate to the developing fruit which they burrow into and start feeding. The mature caterpillar exits the fruit and spins its cocoon under bark scales. Several of the larvae overwinter in cocoons, pupating in the spring of the following year. In warm climates, the majority of the larvae pupate in the same year, so, a second generation may develop, which then takes flight in August and September.

      Symptoms & Diagnosis

      Pattern of damage

      The damage from codling moths is caused by the caterpillar (larva that grow up to 2 cm long), which mines through the apple all the way to the core (Picture 3). When feeding, dark-colored feces mixed with fruit flesh is disposed of through the entry hole (Picture 4).
