Biological notes on the emergence of mountain pine beetle and associates from lodgepole pine, Gallatin Ranger District, Gallatin National Forest, Montana, 1975

Creator:: Hamel, Dennis R., McGregor, Mark D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Emerged beetles were first collected July 17 and peak emergence occurred between August 10 and 26, 1975. Density of attacks averaged four per 0.5 ft. 2 (0.05 m2). Parent to brood ratio was 1:4.6. Thirteen associate insects, representing six families of Coleoptera and one of Diptera, were recovered. Associates included...

Creator:: McGregor, Mark D., Hamel, Dennis R., Lood, Rudolph C., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle has occurred at epidemic level in lodgepole pine stands in the west Gallatin River drainage since 1969. Infestation now encompasses about 5,500 acres. Since 1969, approximately 463,212 trees, with an estimated volume of 20,529,244 board feet have been killed. Approximately 69 percent of the stands on the...

Creator:: McGregor, Mark D., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle reached epidemic levels in the Lazier-Meadow Creek drainages on mixed ownership in 1972. A total of 118,486 trees with an estimated volume of 5,666,124 board feet was killed from 1972 through 1974. Presence of overstocked, mature, nearly pure lodgepole stands, coupled with favorable weather conditions, are believed...

Status of mountain pine beetle infestations, Glacier National Park, 1974

Creator:: McGregor, Mark D., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations reached epidemic levels on approximately 4,600 acres in Glacier National Park in 1972. Infested trees increased from 4.9 in 1972 to 10.9/acre in 1975. Majority of trees killed since 1972 were 12 inches d.b.h. and larger in size. Sufficient large diameter lodgepole pine exists to maintain...

Evaluation of a weevil infestation in thinned lodgepole pine stands, Lewis and Clark National Forest, Montana

Creator:: Hamel, Dennis R., McGregor, Mark D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: An infestation of a defoliating weevil, Magdalis gentilis LeConte, was reported in July by Hank Manning, Judith Ranger District forester, Lewis and Clark National Forest. The infestation occurs in precommercially thinned stands of lodgepole pine, Pinus contorta var./atifblia Engelm. in the Moose Creek drainage. Although damages caused by M. gentilis...

Creator:: Carlson, Clinton E., Bousfield, Wayne E., McGregor, Mark D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Stepwise multiple regression techniques were used to statistically analyze the relationships between damage caused by the pine needle sheath miner Zellaria haimbachi (Busck); a needle miner, Oenerostoma etrobivorum (Zeller); sugar pine tortrix, Choriatoneura Zambertiana (Busck); and ambient and foliar concentrations of fluoride in lodgepole pine (Pinue contorta v.

Establishment report : permanent mountain pine beetle population trend plots, Montana, 1979

Creator:: Gibson, Kenneth E., McGregor, Mark D., Bennett, D. D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Thirty permanent mountain pine beetle population trend plots were established in each of six areas in the state in 1979. Infestation levels ranged from 0 to 47.8 new attacks per acre. The potential for increased mortality is considered high for all areas. Each area will be evaluated for 5 years...

Evaluation of mountain pine beetle infestation, Hebgen Lake Ranger District, Gallatin National Forest, Montana, 1978

Creator:: McGregor, Mark D., Bennett, D. D., Meyer, Hubert E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations developed to epidemic level in 1970 on the Hebgen Lake Ranger District. Infested acreage increased from 78,000 in 1977 to 79,061 in 1978. More than 4 million trees (238 MMBF) were killed in 1978. Cold temperatures during December 1978 may cause a significant decline in the...

Status of mountain pine beetle infestation, Bozeman-Gallatin Ranger District, Gallatin National Forest, 1977

Creator:: McGregor, Mark D., Hamel, Dennis R., Meyer, Hubert E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle populations developed to epidemic level on the Bozeman-Gallatin Ranger District in 1969. Approximately 146,000 acres are currently infested. Since 1969, over 350 MMBF have been killed. It is predicted that over 4 million trees could be killed in 1978. Infestation is predicted to intensify in high-hazard stands....
