  Citation × Citation Citation Abstract Copy Title: Potential for defoliation of ponderosa pine stands by pine butterfly on the Bitterroot and Lolo National Forests, Montana in 1972 Author: Meyer, Hubert E., United States. Forest Service. Northern Region. State & Private Forestry, Bousfield, Wayne E. Epidemic levels of the pine butterfly, Neophasia menapia (Felder and Felder) have been evident in ponderosa pine stands in the Bitter Root Valley since 1969. Evaluations of this infestation were initiated in 1970 to assess overwintering egg populations at 20 locations within the infestation (Ciesla et al. 1971). Defoliation was estimated following the feeding period in 1971 and a linear regression model was computed using defoliation as the dependent variable and egg density as the independent variable (Bousfield and Ciesla 1971). The purpose of this study was to provide a basis for predicting future population levels. The objective of this evaluation is to test the prediction model, forecast 1972 defoliation potential, and to obtain additional biological information on the infestation.

Forest Service. Northern Region. State & Private Forestry, Bousfield, Wayne E., Bennett, D. D. 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, photographic interpretation, and ground truth measurements. Estimates of the number of lodgepole killed by mountain pine beetle in 1977 were 1,270,617 trees and 24.2 million cubic feet. The number of total standing dead within the survey boundaries was estimated at 3,117,888 trees and 62.2 million cubic feet. This total standing dead represents 31.4 percent of the total basal area.
