Summer fruit tortrix

The summer fruit tortrix (Adoxophyes orana) is a moth belonging to the order Lepidoptera and the family Tortricidae. It is recognized as a significant pest in fruit-growing regions across Europe and Asia, known for its high reproductive capacity and wide host range.

This pest mainly affects pome and stone fruits, particularly apple, pear, plum, and cherry trees. The larvae are highly polyphagous, meaning they can thrive on various plant species, which creates a constant pressure on commercial orchards located near hedge rows or ornamental gardens.

The life cycle involves multiple generations per year. The insect overwinters as a second or third-instar larva within silk hibernacula situated in bark crevices. As temperatures rise in early spring, the larvae resume feeding, targeting expanding buds, blossoms, and young foliage, which directly impacts the tree's growth potential.

The damage caused by larvae is quite distinctive: they spin leaves together with silk and feed from within these protective structures. When larvae shift to fruits, they scrape the surface or bore holes into the flesh. Such damage often leads to secondary fungal infections and significantly reduces the market value of the harvest.

To effectively manage the summer fruit tortrix, farmers should employ the following strategies:

• Monitoring moth flight patterns using pheromone traps to time treatments correctly.
• Applying biological control agents, such as specific entomopathogenic bacteria.
• Using selective insecticides targeting young larvae before they protect themselves with webbed leaves.
• Maintaining orchard hygiene, including the removal of infested fruits and pruning of affected branches.
