Exotic species are being discovered in the United States yearly. The Early Detection Rapid Response program is designed to detect, monitor, and limit the potential establishment of new exotic species. With these goals in mind, different trap designs and pheromone lure combinations were tested from June to September 2005 in 3 burned areas of Pinus ponderosae to determine the most efficient technique for monitoring woodboring insects. Intercept panel traps, Lindgren funnel traps, and Sante traps were baited with a combination of Synergy ethanol and terpentine lures and monitored weekly. Significantly more insects from the Siricidae, Buprestidae, and Cerambycidae families were collected in the funnel and panel trap designs than the Sante trap design. Three lure combinations: 1) Synergy ethanol and terpentine, 2) Phero Tech ethanol and Synergy ethanol, and 3) Phero Tech ethanol and alpha-pinene were placed on Intercept panel traps. The collections from the traps baited with the Phero Tech ethanol and alpha-pinene combination contained more woodboring insects than the other lure combinations. From these results, it appears that using a combination of ethanol and alpha-pinene on a funnel or a panel trap design would be an effective technique for monitoring forests for exotic species.
