Longhorn beetle Stromatium longicorne

The longhorn beetle Stromatium longicorne belongs to the order Coleoptera and the family Cerambycidae. This insect is recognized as a significant technical pest, primarily affecting the quality of timber and the health of various deciduous and coniferous tree species throughout its habitat range.

This pest attacks a wide range of host plants, including fruit trees in commercial orchards, forest stands, and ornamental trees. Furthermore, it represents a major threat to stored wood products, timber used in construction, and furniture, as it can infest seasoned wood under favorable humidity conditions.

The biological life cycle of Stromatium longicorne is characterized by a prolonged larval stage spent entirely within the wood. Adult beetles lay eggs in bark crevices or surface defects. Upon hatching, larvae bore into the sapwood and heartwood, creating extensive galleries filled with frass, which disrupts the tree's vascular system and structural integrity.

Damage caused by this beetle is severe. In living trees, the tunneling activity causes stunted growth, branch dieback, and eventually the death of the host. In structural timber, the galleries weaken the material, leading to mechanical failure of construction elements and significant financial losses for industries relying on wood products.

Management strategies focus on both prevention and direct control. Sanitation is paramount; removing infested trees and debris reduces the local population. Chemical treatments, such as systemic insecticides or surface applications of wood preservatives, are used to prevent infestation of valuable timber. Monitoring adult activity during the flight season is also essential for timely application of targeted pest control measures.
