Description: Tetropium fuscum (Fabr.) (Coleoptera:Cerambycidae) is native to Europe and apart from the Halifax, Nova Scotia area, is unknown elsewhere in North America (Smith & Hurley, 2000). Tetropium fuscum poses no primary threat to Picea abies Karst. in Europe and is regarded there as a secondary insect that usually attacks severely weakened or recently dead trees. An infestation of Tetropium fuscum was discovered in 1998 in red spruce trees (Picea rubens Sarg.) in the Halifax Regional Municipality in Nova Scotia, Atlantic Canada (Smith and Hurley, 2000). The trees had very little resistance and repeated attacks by the beetles ultimately led to the death of the trees. Several species of ophiostomatoid fungi were found in association with the T. fuscum infestation.
