  • 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...

  • 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...
