Abstract
Bark beetles (Coleoptera, Scolytidae) form a large and diverse group of insects and are among the most economically important pests of forestry in Europe. Examples of aggressive bark beetle species in Europe include the spruce bark beetle Ips typographus on Norway spruce (Picea abies) and the pine shoot beetles Tomicus piniperda and Tomicus destruens on various pine (Pinus spp.) species. Most bark beetles species are vectors of blue-stain fungi, most of which belong to the ascomycete genera Ceratocystis and Ophiostoma and to related anamorph genera. Besides causing stain in the sapwood of infested trees some bark beetle associated blue-stain fungi cause vascular stain diseases and are able to kill healthy trees. Leptographium wingfieldii, associated with Tomicus piniperda and Ceratocystis polonica, associated with Ips typographus are examples of aggressive bark beetle transmitted blue-stain fungi that cause severe disease on their host trees. In recent years, both L. wingfieldii and Ceratocystis polonica have been used to study the anatomical and biochemical defence reactions of spruce and pine.
