codling moth(kŏd`lĭng), small moth, Carpocapsa pomonella, whose larva is the destructive apple worm. Of European origin, it is now found wherever apples are grown. The adult moth is gray with brown markings and has a wingspan of about 3-4 in. (1.8 cm). The 3-4-in. larva is pinkish, with a brown head. There are several generations a year; the early eggs are deposited on leaves and the later ones directly on the developing fruit. The larvae feed inside the fruit and pupate (see insectinsect,

(Carpocapsa [Laspeyresia] pomonella), an insect of the family Tortricidae (leaf rollers), order Lepidoptera. The codling moth, a pest that feeds on various fruits, is distributed in apple-growing regions. The wingspan is 17–22 mm. The front wings are dark gray with wavy crossbands and a large reddish brown spot with a bronze cast near the tip. The back wings are light brown with fringed edges.
The caterpillars damage fruits of apple, pear, peach, plum, and other trees. The fruits fall prematurely, and among those picked there is a considerable percentage of rejects. Control measures consist in clearing trunks and large branches of old, dead bark, which must be destroyed, and spraying fruit trees with insecticides. In orchards, fallen fruit should be removed. Caterpillars can be caught in chemically treated paper bands and destroyed.
