Notocelia

Notocelia is a genus of moths belonging to the family Tortricidae (leafroller moths). These insects are recognized as significant pests in orchards and ornamental gardens, primarily affecting various species of fruit trees and shrubs through the feeding activities of their larvae.

The primary host plants for Notocelia species include pome and stone fruits, such as apple, pear, and plum, as well as plants from the Rosaceae family, including roses and hawthorns. The larvae are notorious for their early-season impact on the development of new buds.

The biological cycle of Notocelia typically involves overwintering as early-instar larvae within silken cocoons located in bark crevices or near bud scales. As spring temperatures rise, the larvae emerge and begin feeding on the sap-rich tissues of developing buds and emerging leaves.

Larval damage is characterized by the destruction of buds, which directly impacts the potential fruit yield. As they grow, the larvae spin silk threads to roll or web leaves together, creating shelters where they feed by skeletonizing the leaf surface, causing significant stress to the host plant.

Effective management strategies require an integrated approach to reduce population density and minimize damage:

• Application of targeted insecticides during the green-tip or bud-burst stage.
• Mechanical cleaning of tree bark to remove overwintering sites.
• Monitoring adult moth activity using pheromone traps to time pesticide applications.
• Regular pruning and removal of infested shoots during the growing season.
