Hawthorn plume moth

Systematic position: The Hawthorn plume moth (Platyptilia crataea) belongs to the order Lepidoptera and the family Pterophoridae. These moths are recognized by their unique wing structure, which appears divided into feather-like plumes.

Host plants: As the common name suggests, the primary host is Hawthorn (Crataegus). However, the larvae are known to infest other members of the Rosaceae family, including apple and pear trees, where they can cause economic damage to both foliage and flowers.

Biology and life cycle: The life cycle is synchronized with the bud burst of host trees. Overwintering usually occurs in the larval stage. As temperatures rise in spring, larvae emerge to feed on developing buds and young shoots. Pupation typically takes place on the plant itself, leading to the emergence of adult moths.

Damage and economic impact: Larvae are considered pests due to their destructive feeding habits. They bore into developing buds, preventing fruit set and stunted shoot growth. Their habit of spinning silken webs around infested leaves makes them less visible and provides protection from predators.

Control measures: Integrated Pest Management (IPM) is recommended to control populations.

• Regular field monitoring to detect early signs of infestation.
• Pruning and destroying affected twigs during the dormant season.
• Application of selective insecticides during the early larval development stage if populations exceed economic thresholds.
