Abstract: The effect of carrion smell on the catching-efficiency of pheromone baited flight barriere traps for the spruce bark beetle Ips typographus L. was studied from June to September 1989 in a spruce forest near Göttingen. We compared the number of spruce bark beetles and carrion beetles catched with 6 pairs of Theysohn-Slit-Traps, baited with Pheroprax^®. The first trap of each pair controlled in regular time intervals of 14 days. The second controlled singulary at the end of the study. If the traps aren't controlled at regular intervals, the catching-efficiency of the traps decreases caused by the dead beetles in the trap. Contemporarily the number of carrion beetles in the traps increases. During the flight of the second generation of Ips typographus controll intervals of 14 days lead to an increased impact of carrion beetles in the traps.
