The potential expansion of mountain pine beetle (Dendroctonus ponderosae Hopkins) from western North America into the Great Lakes Region (Michigan, Minnesota, Wisconsin, and Ontario) could negatively impact eastern pine forests. Currently, no metrics exist to assess susceptibility in the region. I have developed a hazard rating system for the Great Lakes Region that utilizes common attributes of forest structure and composition and have assessed the current susceptibility using the Forest Inventory and Analysis database. The vast majority of plots (∼90%) that contained at least one living pine species were classified as moderately or highly susceptible. Plots on federal (USDA Forest Service) lands had higher susceptibility ratings than those on private or state-owned lands. Ordination results highlighted differences among the susceptibility scores (high, moderate, and low) across plots. Plots with high susceptibility were associated with greater total plot density and pine density, and plots with low susceptibility were associated with lower total plot density and greater overstory species richness. There are still many unknowns regarding mountain pine beetle in the Great Lakes Region; however, as natural resource managers plan for the future, they may want to consider the potential arrival of mountain pine beetle in eastern pine forests when developing silvicultural prescriptions.

Overall Ratio

Five replicates of paired forest blocks containing lodgepole pine, Pinus contorts var. latifolia Engelm., infested by the mountain pine beetle, Dendroctonus ponderosae Hopkins, were chosen in the spring of 1982 in various interior British Columbia locations. Within the experimental block of each pair, one lodgepole pine every 50 m (4 trees/ha) was baited with the attractive semiochemicals myrcene, trans-verbenol and exo-brevicomin. The baiting program caused the attack in 1982 to be concentrated in and around the baited trees, whereas it was more dispersed in the control blocks. The overall ratio of 1982: 1981 attacked trees was 2.5 in the baited blocks and 1.8 in the controls, suggesting that dispersal of beetles out of the baited blocks was inhibited. Baiting of trees with semiochemicals is recommended to contain infestations within prescribed boundaries when sanitation-salvage logging cannot be completed prior to mid-summer flight of emergent brood beetles.

Outbreak Areas

The importance of the mountain pine beetle to the pine forests of North America has been pointed out by several writers (Hopkins, 1909; Swaine, 1918; Evenden et al., 1943; Hopping and Mathers, 1945). Its range covers parts of southern British Columbia and Alberta, Idaho, Montana, Wyoming, Oregon, Washington, California, Utah, and Nevada. The size of populations and the damage vary from year to year. A study of the biology of the mountain pine beetle was made by the writer from 1955 to 1960 in several small outbreak areas near Invermere, British Columbia. (50°30′ N. lat., 116°00′ W. long., 2740 feet above sea level). The host tree in these areas was lodgepole pine, Pinus contorta Douglas var. latifolia Engelmann. The results of the study will be presented in three parts. Part I is presented herein and describes the life cycle, brood development, and flight periods. Part II is a discussion of the behaviour of the adult as affected by physical factors operating under the bark. Part III describes the interaction of the insect and its host, with special reference to mortality and brood survival.
