Release rates of a blend of monoterpenes (spruce blend) and ethanol significantly affected mean trap catch of Tetropium fuscum (F.), Tetropium castaneum L., and Tetropium cinnamopterum Kirby. Addition of an ethanol lure to traps baited with the spruce blend lure was necessary to attract T. castaneum and T. cinnamopterum and significantly increased attraction of T. fuscum. The combination of spruce blend and ethanol at high release rates had the highest mean catch of Tetropium spp. and was the only lure treatment that resulted in capture of T. fuscum and T. castaneum (in Poland) in every test block, suggesting it would be the best for detection surveys among the lures tested. The effect of trap design on mean catch of T. fuscum was inconsistent. In one experiment, the larger collapsible cross-vane Colossus trap caught about twice as many beetles as the IPM-Intercept trap, but in two other experiments, mean catch did not differ significantly. Type of killing agent in the collecting bucket significantly affected mean catch of T. fuscum. Traps with liquid killing agent (50/50 mixture of propylene glycol and deionized water plus 0.5 ml/liter of Kodak Photo-Flo 200 and 12.5 mg/liter of Bitrex) in the collecting bucket caught more beetles than traps with an insecticidal (dichlorvos) strip. Although any of cross-vane traps tested seem suitable for trapping several cerambycid species, the Colossus trap with liquid killing agent is recommended for use as a detection tool for T. fuscum because it caught similar or greater numbers than the other trap types.
