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.

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.
