Abstract
We initiated a multi-year project to protect individual cone-bearing whitebark pines (Pinus albicaulis) from mountain pine beetle (MPB), Dendroctonus ponderosae (Hopkins), attack with the anti-aggregating pheromone, verbenone (4,5,5-trimethylbicyclo [3.1.1] hept-3-en-2-one). Our objective was to protect trees through the course of the epidemic that began ca. 2000 in central Idaho. The study population was a subalpine stand of whitebark pine at 9,400 feet elevation near Clayton, ID. Associated conifer species included lodgepole pine, Douglas-fir and subalpine fir.
