Download or read book Douglas fir Tussock Moth written by Robert W. Campbell and published by . This book was released on 1978 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This annotated bibliography includes references to 338 papers. Each deals in some way with either the Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), or a related species. Specifically, 210 publications and 82 unpublished documents make some reference, at least, to the Douglas-fir tussock moth; 55 are concerned with other species in the same genus. The subject matter in each paper has been indexed to at least one general topic (General, Taxonomy, Biology, Host Relationships, Outbreaks, Control, Related Material). Most of these general topics have been subdivided into more specific headings. For example, Host Relationships includes separate categories for white fir, grand fir, and Douglas-fir. A complete listing of the references in each general and specific category is presented in the index.

Book excerpt: The incidence of baculovirus disease in susceptible insect hosts may be used to estimate future host population sizes and estimate the relative defoliation of these populations for economically important insects. We developed an Enzyme-linked immunosorbent assay (ELISA) that was specific to two native baculovirus pathogens of the Douglas-fir tussock moth (DFTM), that was more sensitive and accurate (R2=0.99) than microscopic counts of virus polyhedron inclusion bodies, and more accurate than PCR or Southern hybridization for the direct detection of baculovirus disease. We also developed a field-based "dipstick" assay that was sensitive enough to detect virus disease prior to host mortality and did not require virus purification from macerated insect tissues, supporting its use for on-site field surveys. Finally, we used ELISA to establish, for the first time, a method to detect persistent sublethal baculovirus infections. Our work may contribute to more accurate understanding of the incidence and influence of persistent sublethal infections on insect hosts.
