Adult moth has 1/2–3/4" wingspan. Back part of tips of front wings have large chocolatebrown patches; remainder is covered with wavy, light gray and brown lines. Larvae are white/pink; grow to 3/4" long. The moths prefer apples, pears, crabapples, walnuts and peaches. Larvae bore straight into the center of the fruit to feed on the seeds. They keep the tunnel open by pushing brown excrement "pellets" out the entrance. Damage is usually extensive and can infest 100% of the fruit on a tree.
Trichogramma minutum, released at about the time the moths are laying their eggs (at petal fall), are widely used for codling moth control. Products containing kaolin clay, as well as Bacillus thuringiensis (Bt), a naturally occurring bacterial disease of insects, have shown to be efficient methods of pest control. We recommend Surround® At Home® Crop Protectant and Green Step™ Caterpillar Control.
