  • Applications

    (-)-Ipsenol (CAS 35628-05-8) is a semiochemical used in forestry and agriculture as an aggregation pheromone component for Ips bark beetles; it is formulated into lure systems and field traps to monitor populations and enable mass trapping or targeted management; it is commonly incorporated in pheromone blends to enhance attraction and species specificity within integrated pest management programs; researchers use Ipsenol as a tool in chemical ecology studies and trap-development work, and as a reference standard in behavioral assays.
