Eye-spotted bud moth

Taxonomic position of the eye-spotted bud moth (Spilonota ocellana) places it within the order Lepidoptera and the family Tortricidae. This moth is a well-known pest in temperate orchards, where it can cause significant economic losses if left unmanaged.

The pest primarily targets a wide range of pome and stone fruit crops. Common hosts include apple, pear, cherry, plum, and various ornamental trees of the Rosaceae family. The severity of infestation often varies depending on environmental conditions and the intensity of orchard maintenance.

Biology and life cycle involves overwintering as second or third-instar larvae within silken cocoons tucked into bark crevices or branch crotches. In early spring, as temperatures rise, the larvae emerge to feed on developing buds. Following pupation and the emergence of adults, eggs are laid on the leaves, leading to a new generation of larvae.

Damage patterns and economic impact are characterized by larvae consuming buds and boring into stems. They typically tie leaves together with silk webbing, creating protective shelters for feeding. Beyond direct tissue destruction, the larvae may feed on young fruits, leaving blemishes that downgrade the fruit's marketability and potential for storage.

Control measures require an integrated pest management (IPM) strategy. This involves monitoring adult moth populations using pheromone traps and inspecting for signs of early spring activity. Chemical control is most effective when targeted at the larval stage before they become protected by webbing or enter the fruit.

• Dormant season pruning to remove overwintering sites.
• Application of bio-rational insecticides during bloom or early development.
• Regular monitoring with pheromone lures for precise spray timing.
• Encouraging natural predators such as braconid wasps and earwigs.
