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 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...

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....

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,...
