Predators associated with hemlock woolly adelgid (Hemiptera: Adelgidae) infested western hemlock in the Pacific Northwest.

Creator:: Kohler, Glenn R.
Abstract:: The hemlock woolly adelgid, Adelges tsugae, is causing widespread mortality of eastern hemlock, Tsuga canadensis, in the eastern United States. In the West, A. tsugae causes negligible damage to western hemlock, Tsuga heterophylla. Host tolerance traits and presence of endemic predators may be contributing to the relative tolerance of western...

Control of the western pine shoot borer Eucosma sonomana Kearfott in selected ponderosa pine plantations in northern Idaho and western Montana

Creator:: Dewey, Jerald E., Livingston, R. Ladd, Kohler, Steve, and Sartwell, Charles
Abstract:: A synthetic pheromone of the western pine shoot borer, Eucosma sonomana Kearfott, has been used successfully as a 'mating disrupter in northern Idaho and western Montana since 1984. Infestation levels in treated ponderosa pine plantations declined from an average of 28 percent infested in 1983 to 5.5 percent by 1986....

Evaluation of a western false hemlock looper infestation in the upper Flathead Valley, Montana

Creator:: Dewey, Jerald E., Kohler, Steve, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A western false hemlock looper, Neptyia freeman Munroe, outbreak was detected in the late summer of 1973 at the north end of Flathead Lake. Defoliation, from barely detectable to heavy (most foliage removed from upper half of trees), occurred on Douglas-fir over about 3,000 acres located between Somers and Kalispell,...

Potential for defoliation by Douglas-fir tussock moth in western Montana in 1974

Creator:: Tunnock, Scott, Kohler, Steve, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: In 1973, two centers of defoliation by Douglas-fir tussock moth totaling 350 acres were detected near Missoula, Montana. Egg mass surveys showed two sections south of Frenchtown and one section northwest of Lolo 41, contain sufficient egg mass population to cause heavy defoliation in 1974.
