Where is it found?

Adoxophyes orana (Summer Fruit Tortrix) is a species of tortrix moth native to Europe (north to central Sweden and southeastern England) and Asia. It is not known to occur in North America.

What does is damage?

It is a pest of apple, cherry, and pear, but also feeds on other Rosaceous hosts, as well as maple, alder, birch, peanut, forsythia, hawthorn, ash, honeysuckle, alfalfa, poplar, oak, rose, willow, elm, and lilac.

The head of the larvae is light brown to yellow. It has a greenish body ornamented with warts and light hairs. Adult moths are about 10 mm long with a wingspan of 15-22 mm, the females slightly larger (wingspan 18-22 mm) than the males (wingspan 15-19 mm). The wings are brownish, marked in a variable dark-brown pattern; males are more brightly coloured than females. At rest, the wings are folded nearly parallel to the body.

Females lay yellow egg masses 3-10 mm diameter in early spring. The larvae hatch and leave behind the transparent shell of the eggs. 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 are 18-22 mm long, and spin a 10-11 mm long cocoon before moulting into the light brown pupae. It will darken as it develops into an adult. Two generations occur per year depending on temperature.

What kind of damage does it produce?

The larvae feed on both foliage and fruit. Damage to foliage is insignificant, but damage to fruit can be serious. On apples, it can be expected that damage from the first generation will result in large deep holes, whereas the second generation produces small holes of less than 5 mm in diameter. Damaged fruit may be secondarily infected by fungal diseases.
