(S)-Ipsdienol is a terpene alcohol. It is one of the major aggregation pheromones of the bark beetle. It was first identified from Ips confusus, in which it is believed to be a principle sex attractant.[1]

It is suggested that the compound plays a role in interspecies communication between Ips latidens and Ips ini, facilitating reductions in competition for breeding material and/or mating interference.[2]


The compound has been synthesized from D-mannitol.[3]
