Creator:: Stimmann, Michael W.
Abstract:: Two populations of the pine needle scale, Phenacaspis pinifoliae (Fitch), were studied. One population was located in Corvallis, Oregon, and the other population was located near Santiam Pass, Oregon. Both populations were feeding on Pinus contorta.

Factors influencing the production and survival of inoculum of Elytroderma deformans

Creator:: Laird, Peter Paul
Abstract:: This study concerns factors affecting production and survival of ascospores of Elytroderma deformans (Weir) Darker, a needle cast of ponderosa pine (Pinus ponderosa Laws.). The results show that summer cooling and a reduction in host vigor delays and diminishes the number of fertile hysterothecia produced. Evidence is offered for classification...

Potential defoliation in 1979 from a ponderosa pine needle miner on the Flathead Indian Reservation and Missoula Valley, Montana

Creator:: Tunnock, Scott, Meyer, Hubert E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A needle miner, Coleotechnites sp., defoliated approximately 3,100 acres of ponderosa pine, Pinus ponderosa Laws. on the Flathead Indian Reservation, Montana, during 1978. Three other small areas in the Missoula Valley were infested also. Overwintering populations of larvae are low; thus, light defoliation is expected in 1979 in presently infested...
