Abstract
AbstractLanding rates as monitored by landing traps indicate that the mountain pine beetle, Dendroctonus ponderosae Hopkins, is not attracted to lodgepole pine, Pinus contorta Dougl., prior to the first gallery start. Bark terpene odors and DBH were not correlated with beetle landing rates, with the exception of beta-phellandrene which accounted for a statistically significant 18% of the variation in landing rates. Beetles were unable to distinguish between hosts, dead hosts and nonhosts during landing. The elderberry pith bioassay indicated the presence of a gallery initiation stimulant in the bark.
