Box 4000, Fredericton, NB, Canada E3B5P7 ([email protected]) Received 28 January 2016; Accepted 11 March 2016 Abstract Detection tools are needed for Monochamus species (Coleoptera: Cerambycidae) because they are known to introduce pine wilt disease by vectoring nematodes in Asia, Europe, and North America. In 2012–2014, we at Don Thomson on June 1, 2016 examined the effects of the semiochemicals monochamol and ipsenol on the flight responses of the sawyer beetles Monochamus carolinensis (Olivier), Monochamus clamator (LeConte), Monochamus mutator LeConte, Monochamus notatus (Drury), Monochamus obtusus Casey, Monochamus scutellatus (Say), and Monochamus titillator (F.) complex (Coleoptera: Cerambycidae) to traps baited with a-pinene. Experiments were set in pine forests in New Brunswick and Ontario (Canada), and Arizona, Georgia, Michigan, Montana, Oregon, South Carolina, Utah, and Washington (United States). In brief, 40 traps were placed in 10 blocks of 4 traps per block per location. Traps were baited with: 1) a-pinene; 2) a-pinene þ monochamol; 3) a-pinene þ ipsenol; and 4) a-pi- nene þ monochamol þ ipsenol. Monochamol increased catches of six species and one species complex of Monochamus with an additive effect of ipsenol for five species and one species complex. There was no evi- dence of synergy between monochamol and ipsenol on beetle catches. Monochamol had no effect on catches of other Cerambycidae or on any associated species of bark beetles, weevils, or bark beetle predators. We pre- sent a robust data set suggesting that the combination of a-pinene, ipsenol, and monochamol may be a useful lure for detecting Monochamus species.

Pine sawyers are broadly attracted to host 2013b). Some borers such as pine sawyers (Monochamus spp.) can volatiles such as a-pinene and bark beetle pheromones such as ipse- carry nematodes that cause pine wilt disease, a disease that has re- nol (Allison et al. 2004, Pajares et al. 2004, Miller et al. 2013b, and sulted in the death of thousands of trees in Asia and now poses a references therein). Pajares et al. (2010) identified monochamol threat to forests in Europe (Wingfield et al. 1982, Evans et al. 1996, (2-undecyloxy-ethanol) as a male-produced aggregation pheromone Vincente et al. 2012). Eight species of Monochamus are native to for Monochamus galloprovincialis (Olivier) (native to Europe). Published by Oxford University Press on behalf of Entomological Society of America 2016.
