Damage by a wood wasp in connection with testing of a new wound dressing. Tests with Fongisil on Norway spruce (Picea abies) and different broad- leaved tree species showed interesting results. Whereas practically no butt rot infection could be observed on the treated wounds of maple, beech or oak, most of the treated wounds of Norway spruce were heavily infected by butt rot. The main reason seems to be the attractance of a horntail (Urocerus tardigradus) by the yellow colour of the tested wo- und dressing. After this experience the colour of Fongisil was changed to "natural brown".
