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...

Evaluation of mountain pine beetle infestations, Gallatin Ranger District, Gallatin National Forest, Montana, 1975

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...

Evaluation of mountain pine beetle infestations, Lazier and Meadow Creek drainages, Plains District, Lolo National Forest, Montana, 1975

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...

A pilot survey to measure annual mortality caused by the mountain pine beetle in lodgepole pine on the Beaverhead and Gallatin National Forests, 1978

Creator:: Bennett, D. D., Bousfield, Wayne E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A multistage sampling survey to measure annual and cumulative mortality of lodgepole pine by mountain pine beetle was conducted on the Beaverhead and Gallatin National Forests, 1978-79. The survey area, 270,000 acres, was stratified into three intensity classes from aerial sketchmapping. This was followed by large scale (1:6,000) aerial photography,...

Permanent mountain pine beetle population trend plots : an update, 1981

Creator:: Gibson, Kenneth E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Six Montana areas in which permanent mountain pine beetle trend plots were established in 1979 were revisited in 1980. Results of the visit show infestation intensity decreased significantly in Centennial Valley, decreased slightly in the Madison River plot area, and increased almost threefold in the Murr Creek area. Beetle populations...

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...
