Mountain pine beetle status and potential, Plains/Thompson Falls Ranger District, Lolo National Forest

Creator:: Gibson, Kenneth E. and United States. Forest Service. Northern Region
Abstract:: The series of mountain pine beetle infestations existing on the Plains/Thompson Falls Ranger District, Lob National Forest, since 1971 continued into 1988. While some infestations are waning, others are increasing. The potential for beetle-caused mortality exists in threatened, but as yet uninfested stands. Management alternatives are discussed.

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...
