Status of insects and diseases on eastside national forests and adjoining state and private lands, 1984

Creator:: Gibson, Kenneth E., Dooling, Oscar J., and United States. Forest Service. Northern Region
Abstract:: Insects and diseases have the potential of seriously affecting timber associated resources on eastside forests within the foreseeable future. Within the past decade, lodgepole pine mortality attributed to the mountain pine beetle has totaled tens of millions of trees on the Gallatin and Beaverhead National Forests (NF) alone. In that...

Abstract:: Mountain pine beetle populations increased in 1979 in the Thompson River drainage to levels predicted following the 1978 attack period. New attacks in 1979 averaged 27 per acre. Current estimates indicate another 25 percent of the remaining lodgepole pine could be killed in 1980.

Effects of Dipel wettable powder for foliage protection against western spruce budworm 1 and 2 years following aerial application

Creator:: Bousfield, Wayne E., Flavell, Thomas H., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: This evaluation showed that Bt provided measurable foliage protection 1 year after treatment, but no differences were evident after 2 years. We recommend future Bt tests include postspray population measurements in the pupal and/or adult, and/or egg stage, and that foliage protection be measured the following year. The effects of...

Evaluation of multistage sampling techniques to measure lodgepole pine mortality caused by mountain pine beetle in Montana, 1979

Creator:: Bennett, D. D. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A pilot survey was conducted to evaluate the effectiveness of using multistage sampling techniques to measure annual and cumulative mortality on a State-wide basis with acceptable statistical reliability, timeliness, and cost. Within the State of Montana, aerial surveys showed about 986,000 acres of lodgepole pine infested with mountain pine beetle....
