  Introduction An intensive study of the population dynamics and arthropod associates of larval Douglas-fir tussock moth, (Orgyia pseudotsugata (McDunnough)), was conducted from to in the EI Dorado National Forest, California. Arthropod predation on early instars of this moth has been documented as a key factor in intergenera- tion survival (Dahlsten et al. ; Mason , Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), populations were studied on white fir at four areas in central Sierra Nevada mountains of California during –   Fichter, B.

The Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), is a common defoliator of fir in the interior forests of western North America. It is one of four western species of Orgyia, but it is the only member of the group that occasionally reaches outbreak numbers while feeding exclusively on conifers. 24 Because of the explosive and destructive nature of its outbreaks, the

Old-growth forests have become rare in North America but provide habitat for unique assemblages of species that often are rare in younger forests. Insects and related arthropods reach their highest diversity in old-growth forests because of their stable moderate temperature and relative humidity and the rich variety of resources represented by high plant species richness and structural :// Tussock moth: Orgyia pseudotsugata MNPV (OpMNPV) NC_ Douglas-fir tussock moth: Peridroma alphabaculovirus isolate GR (PespNPV) NC_ Pearly underwing, cutworm: Plutella xylostella multiple nucleopolyhedrovirus (PlxyMNPV) NC_ Diamondback moth, cabbage moth: Pseudoplusia includens SNPV IE (PsinSNPV-IE) NC_

1. Introduction. As pear and apple growers in the Pacific Northwestern region of the United States shift to more selective control technologies for major arthropod pests, there is often a noticeable increase in densities of natural enemies in the orchards (Epstein et al., , Knight et al., , Miliczky et al., ).In some instances, increased natural enemy density has been shown to The arthropod hosts of entomogenous fungi in Britain.
