    Description / Table of Contents: Zusammenfassung Die Wirkung von Aasgeruch auf die Fangleistung von Flugbarrierefallen ist im dritten Quartal 1989 untersucht worden. Werden Theysohn-Schlitz-Fallen, beködert mit dem Buchdruckkerlockstoff Pheroprax®, nicht genügend kontrolliert und geleert, so nimmt die Buchdrucker-Fangleistung der Fallen aufgrund des von den bereits gefangenen toten Käfern ausgehenden Aasgeruches ab. Gleichzeitig kommt es zu einem beträchtlichen Mitfang von Aaskäfern. Eine regelmäßige Leerung der Fallen ist daher für eine erfolgreiche, sachgemäße Kontrolle der Buchdruckerpopulationen notwendig. Schon bei 14tägigen Kontrollabständen kann es während der Flugzeit der zweiten Buchdrukkergeneration zu einem erhöhten Mitfang von Aaskäfern kommen.
    Notes: Abstract The effect of carrion smell on the catching-efficiency of pheromone baited flight barriere traps for the spruce bark beetleIps 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 ofIps typographus controll intervals of 14 days lead to an increased impact of carrion beetles in the traps.
