Creator:: Ciesla, William M., Lood, Rudolph C., Bousfield, Wayne E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Aerial surveys of the Nezperce National Forest in Idaho revealed 138,692 acres of aerially visible top kill and tree mortality due to repeated defoliation by western spruce budworm, Choristoneura occidentalis Freeman. A small ground sample indicates that up to 47 percent of the grand fir volume was affected by top...

3. Forecasting western spruce budworm defoliation in mixed conifer stands by counting hibernating larvae

Creator:: Tunnock, Scott and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: An attempt was made in January 1971 to relate the numbers of hibernating western spruce budworm larvae on a square foot of bark surface with subsequent shoot damage on Douglas-fir and grand fir in northern Idaho. Twenty-six plots sampled in January were also sampled in April to determine if larval...

5. Ground application of dimethoate (Cygon) for the control of cone and seed destroying insects of Douglas-fir and grand fir

Creator:: Dewey, Jerald E., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Two concentrations of dimethoate were applied with a hydraulic ground sprayer to cone-bearing Douglas-fir and grand fir trees. Single application (mid-June) and a double application (mid-June and mid-July) were compared. Three of the four treatments applied to Douglas-fir resulted in a significantly higher number of sound seeds produced per cone...

8. Evaluation of mountain pine beetle infestations, Snell Creek and Warland Peak areas, Fisher River District, Kootenai National Forest, Montana

Creator:: Hamel, Dennis R., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle infestations in the Snell Creek and Warland Peak areas were evaluated in October 1975. Based on current buildup ratios, tree diameter distributions, stand composition and phloem thicknesses, there appears to be limited opportunity for epidemic potential in either area. Management alternatives are discussed. Selective logging is recommended...
