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...

Creator:: Leisy, Douglas J.
Abstract:: The genome of the multicapsid nuclear polyhedrosis virus of Orgyia pseudotsugata (OpMNPV) was mapped by examining overlapping Hindlll fragments from cosmid clones which had been constructed from partial Hindlll digests of viral DNA. Five OpMNPV cosmid clones containing fragments encompassing the entire OpMNPV genome were hybridized to blots of DNA...

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...

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...
