Detection survey for Douglas-fir tussock moth infestations in the northern region, 1972

Creator:: Tunnock, Scott and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The last outbreak of the Douglas-fir tussock moth, Hemerocampa pseudotsugata McD., in the Northern Region subsided in 1965. Tussock moth populations were not detected again until 1970 when ornamental spruce were defoliated in Spokane, Washington, and Poison and Missoula, Montana.

Pheromone-mediated behavior of adult Douglas-fir tussock moths, Orgyia pseudotsugata (McD.) (Lepidoptera: Lymantriidae)

Creator:: Swaby, James Archie
Abstract:: The sinuous flight behavior of male Douglas-fir tussock moths, Orgyia pseudotsugata, (McD.), is characterized by positive anemotaxis and positive chemoklinotaxis and varies depending on distance from the pheromone source, population density, and time of day. Visual cues play a minor role in close-range orientation to a pheromone source, but males...

Some strategies for controlling the Douglas-fir tussock moth by regulation of budbreak

Creator:: Cobb, Jimmie Osborn
Abstract:: The young larvae of the Douglas-fir tussock moth (Orgyia pseudotsugata (McDunnough) (DFTM) are dependent on the new foliage of its ho'sts (Doug1as-fir, grand fir, white fir) for their food supply. The phenology of the DFTM and its hosts are synchronized, with egg hatch and dispersal occurring one to three weeks...

Douglas-fir tussock moth in northern Idaho and western Montana : current activity and historical patterns

Creator:: Sturdevant, Nancy J., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: The objective of this report is to describe the current increase in Douglas-fir tussock moth (Orgyia pseudotsugata McDunnough) activity in northern Idaho and Montana. The report also relates current conditions to historical and future trends and larger scale increasing tussock moth activity in surrounding western states.

Arboreal arthropod predation on early instar Douglas-fir tussock moth

Creator:: Fichter, Becky L.
Abstract:: Loss of early instar Douglas-fir tussock moth (Orgyia pseudotsugata McDunnough) (DFTM) has been found to constitute 66-92% of intra-generation mortality and to be a key factor in inter-generation population change. This death has been attributed to dispersal and to arthropod predation, two factors previously judged more important to an endemic...

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.

Impact of egg viability, egg parasitism, and virus on 1974 Douglas-fir tussock moth defoliation potential in western Montana

Creator:: Tunnock, Scott and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Douglas-fir tussock moth egg mass studies during winter 1974 indicate that natural factors such as low egg viability, egg parasitism, and virus do not alter the potential for heavy defoliation in two sections south of Frenchtown and one section northwest of Lolo, Montana.
