Abstract

Two formulations of pine oil (BBR2 and Norpine 65) were tested for effectiveness in preventing attacks by mountain pine beetle and reducing brood production at different population levels on lodgepole pine trees. Pheromone-baited trees sprayed with BBR2 had a lower attack intensity than baited check trees and a lower brood success than either baited check trees or baited trees sprayed with Norpine 65. Only at a low population level was attack intensity reduced by both pine oil treatments. The proportion of attacked trees within 10m of the treated trees was lower in low than in high populations but showed no difference among treatments.
