From 1996 through 1999, field tests of various engraver beetle (Ips perturbatus (Eichhoff)) semiochemical in funnel traps were conducted in south-central and interior Alaska in stands of Lutz (Picea x lutzii Little) and white spruce (P. glauca (Moench) Voss). The European spruce beetle (I. typographus (L.)) is believed to be taxonomically similar to I. perturbatus. Commercially available European spruce beetle lures, which include 2-methyl-3-buten-2-ol, however, were no more attractive to I. perturbatus than the combination of racemic ipsdienol and 83%-(+)-cis-verbenol. The addition of >97%-(--)-ipsenol to ipsdienol and cis-verbenol, however, was more attractive than the binary combination alone. Racemis ipsenol dispersed from bubble caps did not prevent I. perturbatus from colonizing fresh logging debris. Thus ipsenol was found to function as an attractant rather than as an antiaggregant as previously shown.
