Potential for defoliation of ponderosa pine stands by pine butterfly on the Bitterroot and Lolo National Forests, Montana in 1972

Creator:: Bousfield, Wayne E., Meyer, Hubert E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Epidemic levels of the pine butterfly, Neophasia menapia (Felder and Felder) have been evident in ponderosa pine stands in the Bitter Root Valley since 1969. Evaluations of this infestation were initiated in 1970 to assess overwintering egg populations at 20 locations within the infestation (Ciesla et al. 1971). Defoliation was...

Mexacarbate and Bacillus thuringiensis for control of pine butterfly infestations : Bitterroot National Forest, Montana, 1973

Creator:: Dewey, Jerald E. and United States. Forest Service. Northern Region
Abstract:: Aerial application of mexacarbate and Bacillus thuringiensis Berliner was tested against pine butterfly, Neophasia menapia (F. and F.). These were applied to 40-acre plots on the Bitterroot National Forest and adjacent State and private lands during June 1973. Two concentrations of each material were tested; these were 0.15 and 0.30...

Evaluation of proposed dwarf mistletoe projects, West Fork Ranger District, Bitterroot National Forest, Montana

Creator:: Dooling, Oscar J., Underwood, Stanley K., and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Residual Douglas-fir and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning of dense patches of regeneration, will reduce dwarf mistletoe intensity and increase future volume yields. Present net worth of the projects ranges from -$1 to $39 per...

Evaluation of mountain pine beetle infestations, Lap, Cool, Lang, and Caribou Creek drainages, Yaak Ranger District, Kootenai National Forest, Montana

Creator:: Hamel, Dennis R., McGregor, Mark D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle reached epidemic levels in the Lap, Cool, Lang, and Caribou Creek drainages in 1974. From 1973 to 1975, approximately 56,282 trees with an estimated volume of 4,365,660 board feet were killed in these areas. An additional 61,721 trees are predicted to be killed in 1976. Currently infested...

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...

Evaluation of a proposed dwarf mistletoe management project on the Sula Ranger District, Bitterroot National Forest

Creator:: Dooling, Oscar J. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Residual Douglas-fir left after harvesting are dwarf mistletoe infected and pose a threat' to regeneration in some units. Removal of residuals, coupled with planned or completed site preparation and thinnings, will effectively reduce dwarf mistletoe incidence and increase future volume yields. The benefit/cost ratio based on timber values alone is...

Evaluation of proposed dwarf mistletoe management projects on the Sula Ranger District, Bitterroot National Forest

Abstract:: Residual Douglas-fir in older clearcuts are dwarf mistletoe-infected and pose a threat to regeneration present. Removal of these residuals coupled with planned or completed precommercial thinnings will effectively reduce dwarf mistletoe to an insignificant level and increase future volume yields. The benefit/cost ratio based on timber values alone is negative,...

Status of mountain pine beetle infestations, Kootenai National Forest, Montana, 1977

Creator:: McGregor, Mark D. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations increased to epidemic levels on the Kootenai National Forest in 1972. Nearly 397,000 trees containing almost 32 million board feet have been killed. More than 84,000 trees will probably be killed in 1978. Infestation has the potential to intensify in high hazard stands, and some increase...
