Use of synthetic pheromones for the control of spruce bark beetle in a heavily infested Norway spruce stand

The dying-off of more trees in an over-aged Norway spruce ( (L.) H. Karst.) stand caused by -bark beetles was reduced by a pheromone preparation, ipslure. 20 preparations placed in trapping bolts captured more than 13,700 specimens of and 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;,,,.Picea abiesIps Ips typographus L.Ips duplicatusThanasimus formicariusT. rufipes,Epuracea bickhardtiRhizophagus ferrugineusPityophagus ferrugineus
