Adoxophyes orana, Summer Fruit Tortrix Moth

The summer fruit tortrix moth, Adoxophyes orana is a major pest of fruit crops, particularly apple and pear, in temperate regions.

Hosts of this polyphagous pest also include some forest tree species (CABI 2004). Adoxophyes orana has been detected throughout much of Europe and Asia but is not known to occur in the United States (CIE 1982).

The Summer Fruit Tortrix Moth feeds on a wide variety of forest tree, but prefers apple, pear, cherry, plum and apricot. It has the two generations in a year, one in the summer and the other in the autumn. This moth is reported to feed and develop on more than 50 plant species in multiple families including fruits, forest trees, and ornamentals.

OVERVIEW

There are two generations of this species in a year. The first generation summer caterpillars usually appear in June and attack the leaves. In case of severe infestations caterpillars migrate to the fruit.

The 2nd-generation adults appear in August -September, mate and lay eggs. These are known as autumn caterpillars. They then seek a place for overwintering. Adult female lay in batches of 100-150 eggs and last 25-30 days. Larval stages pass through four instars within 18-21 days. Pupae are dark brown in colour. Pupal development period is 15-20 days.

Trap application guidelines

The Deltra trap is the most sensitive trap to use for monitoring this insect. However, Moth catcher may be used in dusty conditions or in high moth population density. Do not re-use the trap to monitor different insects as this may lead to mixed catches. One trap for every two hectares of large scale fields of homogenous lands.

Monitoring

Lures for pest monitoring

Lures

Lures can be changed every 4-6 weeks to get the most accurate results.

Lures handling

Pheromone lures are a very sensitive tool. They can be affected by exposure to elevated heat and direct sunshine. Direct touching by hand may cause cross contamination leading to mixed catches in the trap. Some contaminants such as Nicotine May have repellent effect reducing trap catch.

Lure Storage

Store in a cool dry place.

Shelf life can vary from 3-36 months depending on the storage temperature.
