In 2006, we tested the responses of the small southern pine engraver, Ips avulsus (Eichhoff) (Coleoptera: Curculionidae), to multiple-funnel traps baited with ( )-, (-)-, and (±)ipsdienol. Three experiments were conducted in Georgia with all traps co-baited with one of the following lure combinations, respectively: experiment 1, ipsenol; experiment 2, lanierone and (-)α-pinene; and experiment 3, ipsenol, lanierone, and (-)-α-pinene. Ipsdienol and lanierone are aggregation pheromones used by I. avulsus, whereas ipsenol is an aggregation pheromone used by the eastern fivespined ips, Ips grandicollis (Eichhoff), a sympatric species also breeding in pines. In all experiments, the highest catches of I. avulsus were obtained in traps baited with (±) -ipsdienol. The relative attractiveness of ( )-ipsdienol varied across the three experiments. When traps were cobaited with ipsenol, lanierone, and (-)-α-pinene, catches of I. avulsus in traps baited with ( )ipsdienol were high and no different from those in traps baited with (±) -ipsdienol. When traps were co-baited with lanierone and (-)-α-pinene, catches in traps baited with ( ) -ipsdienol were lower than those in traps baited with (±)-ipsdienol by ≈40%, whereas catches were reduced by ≈95% when traps were co-baited with ipsenol alone. We hypothesize that the observed variation in enantiospecific responses of I. avulsus to ipsdienol may be explained by variation in semiochemical context (i.e., different co-baits among the experiments) or seasonal variation.
