Endoclita undulifer

Systematic position: The pest belongs to the order Lepidoptera, family Hepialidae. It is a specialized pest of woody and shrubby plants, which, during its larval stage, leads a concealed mode of life inside the plant tissues.

Host plants: Endoclita undulifer poses a significant threat to forest and fruit crops. Tree species used in ornamental gardening and forestry are most frequently affected by the larvae, which bore deep tunnels into the trunks and branches of broad-leaved trees.

Biology and life cycle: The insect's life cycle is closely tied to the condition of woody tissues. Adult moths lay eggs on the bark or near the base of the plant. Upon hatching, the larvae penetrate the bark and gradually burrow into the wood, where they spend the majority of their developmental stage, feeding on the phloem and sapwood for several months.

Damage and economic significance: The primary damage is caused by the larvae, which create winding tunnels within the trunks and branches. This disrupts sap flow, weakens the tree, slows down growth, and in cases of severe infestation, can lead to the wilting of branches or the death of the entire plant. Frass and sawdust accumulations near the entrance holes are typical indicators of an infestation.

Control measures: Controlling this pest is challenging due to its concealed life cycle. Essential methods include:

• Proactive inspections of tree trunks for entrance holes in the bark.
• Mechanical cleaning of tunnels and the use of systemic insecticide injections directly into the cavities.
• Removal and proper destruction of heavily infested branches to reduce population levels.
• Maintaining optimal horticultural practices to improve the overall resilience of the trees.
