Abstract
We determined the response of the small southern pine engraver,
Ips avulses (Eichhoff); eastern fivespined ips,
Ips grandicollis (Eichhoff); sixspined ips,
Ips calligraphus (Germar); and pine engraver,
Ips pini (Say) to the pheromones (±)-ipsenol, (±)-ipsdienol, and lanierone in the southeastern United States. Catches of I.
avulsus and I.
grandicollis to baited multiple-funnel traps wereincreased by (±)-ipsenol and (±)-ipsdienol in Florida, Georgia, Louisiana, and North Carolina. In all four localities, the highest numbers of I.
avulsus were caught in traps baited with the combination of (±)-ipsenol, (±)-ipsdienol, and lanierone. In Florida, the highest numbers of I.
grandicollis were captured in traps baited with the combination of (±)-ipsenol and (±)-ipsdienol (with or without lanierone). In the remaining three localities, the largest catches of I.
grandicollis occurred in traps baited with (±)-ipsenol alone or the combination of (±)-ipsenol and (±)-ipsdienol (with or without lanierone). (±)-Ipsdienol was the only consistent attractant for I.
calligraphus and I.
pini. Attraction of I.
pini in North Carolina to (±)-ipsdienol-baited traps was synergized by lanierone but interrupted with (±)-ipsenol. The interruptive effect of (±)-ipsenol on attraction of I. pini to (±)-ipsdienol was negated by lanierone. (±)-Ipsdienol was attractive to black turpentine beetle,
Dendroctonus terebrans (Olivier), in Florida but not North Carolina, whereas (±)-ipsdienol was attractive to I.
calligraphus in Louisiana, Georgia, and Florida. Both (±)-ipsenol and (±)-ipsdienol affected catches of
Gnathotrichus materiarus (Fitch) in North Carolina. Trap catches of
Hylurgops rugipennis pinifex (Fitch), ,
Hylastes salebrosus Eichhoff, and
Hylastes tenuis Eichhoff were unaffected by the pheromone treatments. The combination of (±)-ipsenol, (±)-ipsdienol, and lanierone may be a cost-effective general lure for I.
avulsus, I.
grandicollis, and I.
