DescriptionTraps baited with Seudenol + a-pinene caught 87 percent more eastern larch beetles, Dendroctonus simplex LeConte, than did tamarack logs infested with females. Male beetles responded to the synthetic attractant in greater numbers than females. Male beetles were not attracted to frontalin, a principal attractant of the closely related Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins. Attraction was reduced by 92 and 86 percent by addition of methylcylohexenone (MCH) and frontalin but by only 36 percent when trans-verbenol was added. This evidence partially supports the taxonomic separation of the two Dendroctonus species.
