Most (42 of 54) specimens of Ips grandicollis   (Eichhoff) were captured in Lindgren funnel traps in the canopy of trees (many other individuals were not vouchered). Specimens were captured in the canopy of eastern white pine (26), balsam fir (1), and red pine (9). The other individuals were captured in stands with white pine and jack pine present. White pine was the only pine present at the Bathurst and Currie Mountain sites, indicating that white pine may be a host for Ips grandicollis   in NB.
