To evaluate pathogenicity of some fungi associated with Tetropium spp. (Coleoptera: Cerambycidae): Grosmannia piceiperda, Grosmannia penicillata and Ophiostoma tetropii the inoculation of Norway spruce (Picea abies) trees experiment was performed. The inoculation densities were 400 and 800 points/m2 in a 60 cm wide band at breast height. The effects of inoculation were examined 23 weeks after treatment. Two trees inoculated with G. piceiperda were dying at harvest. Inoculation with G. piceiperda produced significantly greater phloem and sapwood lesions in comparison with other fungi and control. Moreover, the percentage of occluded sapwood was also highest following G. piceiperda inoculations at 800 points/m2. Ophiostoma tetropii, however, produced more occlusions than G. piceiperda at 400 points/m2. These preliminary results suggest that G. piceiperda is pathogenic and may contribute to the mortality of spruces infested by Tetropium beetles.
