This pest considered as “secondary” pest and proliferates by the means of the trees which are in its spreading environment. 8-toothed spruce bark beetle damages the tree by feeding on the tissue under the bark during larvae and adult stages. While deforming the tissues under the barks of the tree it leads to a decrease of the resistance of the tree and to its death later on.
Individual bark beetles that leave the dead trees are spreading to other stands and keep on invading the area.
Method of control:
Mass capture is enabled withspecial pheromone traps.
They generate 2-3 generations per year and flights start between March and September. Trapping must be done in the fields between March and September.
