    Notes: Abstract Ipsenol was identified from the frass of male, but not female,Ips latidens from British Columbia, feeding in phloem tissue of lodgepole pine,Pinus contorta var.latifolia. The responses ofJ. latidens to sources of ips-enol andcis-verbenol were determined with multiple-funnel traps in stands of lodgepole pine in British Columbia. Ipsenol attracted both male and femaleI. latidens, verifying that it is a pheromone for this species. MaleI. latidens showed a slight preference for (S)-(−)-ipsenol.cis-Verbenol was not produced by beetles of either sex and, in contrast to an earlier report, both enantiomers inhibited attraction to ipsenol-baited traps. The predators,Enoclerus sphegeus andThanasimus undatulus (Cleridae), were attracted to traps baited withcis-verbenol and ipsenol.

    (S)-(+)-Ipsdienol: Interspecific inhibition ofIps latidens (leconte) byIps pini (Say) (Coleoptera: Scolytidae) (1992)
    Springer
    Journal of chemical ecology 18 (1992), S. 1577-1582

    ISSN: 1573-1561
    Keywords: Coleoptera ; Scolytidae ; Ips latidens ; Ips pini ; interspecific communication ; synomone ; pheromone ; ipsenol ; ipsdienol ; chirality ; enantiospecificity

    Notes: Abstract In south-central British Columbia, the attraction ofIps latidens (LeConte) to its pheromone, ipsenol, was inhibited by (S)−(+)-ipsdienol, a pheromone forI. pini (Say). (R)-(−)−lpsdienol had no effect onI. latidens. (S)−(+)-lpsdienol probably plays a role in interspecific communication between the two species, facilitating reductions in interspecific competition for breeding material and/or interspecific mating interference.

    β-Phellandrene: kairomone for pine engraver,Ips pini (Say) (Coleoptera: Scolytidae) (1990)
    Springer
    Journal of chemical ecology 16 (1990), S. 2519-2531

    Keywords: Kairomone ; β-phellandrene ; ipsdienol ; monoterpenes ; Ips pini ; Coleoptera ; Scolytidae ; predators ; competition ; primary attraction ; dose response

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The responses ofIps pini (Scolytidae) to multiple-funnel traps baited with the pheromone, ipsdienol, and various monoterpenes were determined in stands of lodgepole pine in southern and central British Columbia.Ips pini was attracted to both ipsdienol and β-phellandrene, demonstrating that β-phellandrene is a kairomone for this species.Lasconotus complex (Colydiidae) and aCorticeus sp. (Tenebrionidae) were attracted to both ipsdienol and β-phellandrene. TheCorticeus sp. exhibited a synergistic response to the combination of ipsdienol and β-phellandrene; the responses of the other two species to the combination were additive. The predators,Thanasimus undatulus, Enoclerus sphegeus, andE. lecontei (Cleridae), were attracted to ipsdienol-baited traps, whileMonochamus clamator (Cerambycidae) andDendroctonus ponderosae (Scolytidae) were attracted to β-phellandrene. Attraction of all eight species increased with increasing release rates of ipsdienol and/or β-phellandrene.
