Ipsenol and ipsdienol attract Monochamus titillator (Coleoptera: Cerambycidae) and associated large pine woodborers in southeastern United States.
We determined the responses of the southern pine sawyer, Monochamus titillator (F.) (Coleoptera: Cerambycidae), to the pheromones (ipsenol, ipsdienol, and lanierone) used by pine engraver beetles (Coleoptera: Scolytidae) in the southeastern United States. (+/-)-Ipsenol, (+/-)-ipsdienol, or a combination increased catches of M. titillator in Florida, Louisiana, Georgia, and North Carolina. Catches of Acanthocinus obsoletus (Olivier) (Cerambycidae) were increased by (+/-)-ipsenol and (+/-)-ipsdienol in Florida and North Carolina, whereas only (+/-)-ipsenol was attractive in Georgia. (+/-)-Ipsenol and (+/-)-ipsdienol were attractive to Pachylobius picivorus (Germar) (Coleoptera: Curculionidae) in Florida, whereas only (+/-)-ipsdienol was active in Louisiana. In Florida, catches of M. titillator, A. obsoletus, and P. picivorus were greatest in traps baited with both (+/-)-ipsenol and (+/-)-ipsdienol. In Louisiana, catches of the woodborer Chalcophora virginiensis (Drury) (Buprestidae) were increased by (+/-)-ipsenol. Lanierone did not affect trap catches of the aforementioned species. The combination of (+/-)-ipsenol and (+/-)-ipsdienol may be a cost-effective lure for these four species because we found no evidence of interruption in attraction to baited traps, and the cost of the lure combination is relatively low.
