The response of T. lineatum to ethanol and a-pinene, when used with the pheromone lineatin, was tested for two trap types. Funnel traps, which are passive barrier traps, caught significantly more beetles than drain-pipe traps, which require an active response by the beetle to enter the trap. However, the response of T. lineatum to the semiochemical treatments did not significantly differ for the two trap types. Treatments that included a-pinene with the pheromone, either with or without ethanol, caught significantly more T. lineatin than those with the pheromone alone. When ethanol and or a-pinene were added to the pheromone significantly more female beetles were trapped than with pheromone alone. Male-female ratios were significantly lower for both types of traps when ethanol was included in the bait than for lineatin alone or with a-pinene. A higher percentage of male beetles entered the drainpipe traps than was captured with funnel traps.
