Alderson & V. Webster // Old red pine forest, Lindgren funnel trap in canopy of red pine (3, AFC; 3, NBM) . Collection and habitat data. Monochamus carolinensis were captured in Lindgren traps baited with a multi-lure combination that included monochamol, ipsenol, alpha-pinene, and ethanol in a jack pine forest, an old black spruce stand with white pine, a mature balsam fir forest with white pine, an old white pine stand, an old red pine forest, and a mixed forest with red oak and white pine. Hosts include various Pinus species according to Yanega (1996) . In New Brunswick, large numbers (many specimens were not vouchered) of adults were captured in a white pine stand, mostly in the canopy. This species was also common in a jack pine stand but uncommon in a red pine forest. These data suggest that white pine may be the preferred host in New Brunswick. This species has a long flight season in New Brunswick from early July to mid-October. Ryall et al (2014) showed that catch of Monochamus carolinensis was significantly increased by baiting traps with monochamol, ipsenol, alpha-pinene and ethanol. Distribution in Canada and Alaska. ON, QC, NB ( Bousquet et al., 2013 ). Comments. Monochamus carolinensis was listed for New Brunswick by McNamara (1991) . Webster et al. (2012a) could not locate any specimens to support its occurrence in the province but included it in the fauna of the province. Bousquet et al. (2013) , however, did not list it as occurring in New Brunswick. The above records support reinstatement of the species to the faunal list of New Brunswick.
