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 of
I. latidens to sources of ipsenol and
cis-verbenol were determined with multiple-funnel traps in stands of lodgepole pine in British Columbia. Ipsenol attracted both male and female
I. latidens, verifying that it is a pheromone for this species. Male
I. 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 , and
Thanasimus undatulus, (Cleridae), were attracted to traps baited with
cis-verbenol and ipsenol.
