Overview

• The invasive box tree moth, first detected in Germany in 2007, continues to spread across Europe, requiring annual management to mitigate damage.
• The moth’s caterpillars feed internally on box trees, making early detection critical to prevent severe defoliation and potential plant death.
• Experts recommend a combination of pheromone traps, biological insecticides, manual removal, and secure pruning disposal to control infestations effectively.
• Reinforced guidance highlights two key treatment periods in spring and midsummer to target overwintered and new caterpillar generations.
• Despite heavy feeding, defoliated box trees can regenerate, but integrated pest management remains essential for long-term preservation.
