Evaluating High Release Rate MCH (3-methylcyclohex-2-en-1-one) Treatments for Preventing Dendroctonus pseudotsugae (Coleoptera: Curculionidae) Infestations

Creator:: Brookes, Harrison M.
Abstract:: The Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins) can kill large numbers of Douglas-fir trees (Pseudotsuga menziesii (Mirbel) Franco) across a landscape during periods of population outbreaks. High-value individual trees and small stands can be protected from Douglas-fir beetle infestation during outbreaks by applying the anti-aggregation pheromone, MCH (3-methylcyclohex-2-en-1-one). MCH treatments are...

Evaluation of the Douglas-fir beetle infestation : North Fork Clearwater River drainage, northern Idaho, 1970-73

Creator:: McGregor, Mark D., Furniss, M. M., Bousefield, W. E., Almas, D. P., Gravelle, Paul J., and Oakes, R. D.
Abstract:: An outbreak of Douglas-fir beetle, Dendroctonus pseudotsugae Hopk., began in 1969 in the North Fork Clearwater River drainage in northern Idaho. This infestation probably resulted from trees felled during clearing for the Dworshak Reservoir, from ice and snow breakage which occurred during the winter of 1968-69 in stands adjacent to...

Creator:: Hamel, Dennis R., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Douglas-fir beetle, Dendroctonus pseudotsugae Hopk., has caused extensive tree mortality in the North Fork Clearwater River drainage since 1971. In 1974, survey estimates indicated a continued decline in the infestation. Average group size decreased from a high of 158 trees per group in 1971 to 17 in 1974. Average area...

Douglas-fir beetle population assessment : Idaho Panhandle National Forests

Creator:: Kegley, Sandy, United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: The unusually large amount of ice, snow, and wind-damaged trees that occurred during the winter of 1996-97 provided prime habitat for populations of the Douglas-fir beetle (DFB) (Dendroctonus pseudotsugae) to build to epidemic numbers. Beetles emerged during the spring and summer of 1998, attacking hundreds of thousands of standing Douglas-fir...

Evaluation of the Douglas-fir beetle infestation in the North Fork Clearwater River drainage, Idaho--1972

Creator:: McGregor, Mark D., Bousfield, Wayne E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The Douglas-fir beetle, Dendroctonus pseudotsugae Hopk., has caused extensive tree mortality for the third consecutive year in the North Fork Clearwater River drainage in northern Idaho. In 1972, the infestation encompassed about 494,080 acres of commercial forest lands in this drainage. It was estimated from a tw-stage aerial photo-ground survey...

Basic and applied studies on Douglas-fir beetle : spatial relationships of infestations, lipids and host habitat, and attraction distances of pheromone-baited traps

Creator:: Dodds, Kevin J.
Abstract:: Three studies on Douglas-fir beetle (DFB), Dendroctonuspseudotsuae, were conducted to investigate its basic and applied biology. Studies included investigations into the spatial relationship of DFB infestations over multiple years and multiple landscapes, relationships between DFB brood adult lipid levels and position of development along the length of tree boles, and...
