%X <p>The dying-off of more trees in an over-aged Norway spruce (<em>Picea abies</em> (L.) H. Karst.) stand caused by <em>Ips</em>-bark beetles was reduced by a pheromone preparation, ipslure. 20 preparations placed in trapping bolts captured more than 13,700 specimens of<em> Ips typographus L.</em> and <em>Ips duplicatus</em>&nbsp;Sahlb., which alone corresponded to a saving of five old trees in this valuable exhibition and seed collection stand. Attractance of ipslure to the following predators of bark beetles was also examined; <em>Thanasimus formicarius</em>, <em>T. rufipes,</em> <em>Epuracea bickhardti</em>, <em>Rhizophagus ferrugineus</em>, <em>Pityophagus ferrugineus</em>.</p>
