Adoxophyes orana (Fischer von Roslerstamm)

Overview

---

The summer fruit tortrix moth is native to Europe and Asia but is not known to occur in the United States. It is a pest of apple, cherry, and pear, but also feeds on other Rosaceous hosts, as well as maple, alder, peanut, birch, hawthorn, forsythia, ash, honeysuckle, alfalfa, poplar, oak, rose, willow, elm, and lilac. Females lay yellow masses of eggs in early spring. The larvae hatch and leave behind the transparent shell of the eggs. The head of the larvae is light brown to yellow. It has a greenish body ornamented with warts and light hairs. When disturbed, the larvae spin a silken thread and descend to escape. This thread is also a possible method for movement via wind. Mature larvae spin a 1/3 to 1/2 of an inch cocoon before molting into light brown pupae. Pupae will darken as it matures. Adult moths are 1/3 to 1/2 of an inch long with brownish wings marked in a variable dark-brown pattern. Males are smaller than females and have brighter colors. Two to three generations may occur per year, depending on temperature. On apple, it can be expected that damage from the first generation will result in large deep holes where as the second generation produces small holes of less than 1/5 of an inch in diameter.
