This bark beetle is considered to be one of the most destructive
pests of spruce on the continent of Europe. Extensive injury to forests
resulting from wars, fires and storms, has at numerous times made possible the
buildup of high populations of the pest which caused excessive secondary
damage. In addition to damaged trees, this species also attacks healthy trees.
The ability to breed in very fresh bark, coupled with the habit of continuing
to feed in the bark on completion of development, makes the insect a serious
pest of spruce forests. |
