Distribution and Ecological roles of arthropods in dead woody materials of ponderosa pine forests, northern California

Creator:: Lemieux, Jeffrey P.
Abstract:: This dissertation describes arthropod responses to and effects on decay processes in ponderosa pine, a dominant forest canopy tree in northern California. We used both descriptive and experimental field techniques to establish how arthropod assemblages depend on and are important to the disintegration of woody structures in forests of this...

Effect of site and silvicultural treatment on insect pests and diseases of young ponderosa pine

Creator:: Norlander, Daniel W. D.
Abstract:: Ponderosa pine is an important species both commercially and ecologically in western North America. This study considers the incidence of insect and disease pests on a series of replicated ponderosa pine research plantations in northern California. The studies, on an environmental gradient, contain a series of silvicultural treatments including vegetation...

Pine butterfly (Neophasia menapia) outbreak in the Malheur National Forest, Blue Mountains, Oregon : examining patterns of defoliation

Creator:: DeMarco, Ariadne T.
Abstract:: The pine butterfly (Neophasia menapia C. Felder & R. Felder) (Lepidoptera: Pieridae) is a relatively host-specific defoliator of ponderosa pine (Pinus ponderosa Dougl. ex Laws). From 2008 to 2012, the Malheur National Forest was subject to an outbreak of pine butterfly in ponderosa pine, peaking at ~100,000 ha of forest...

Candidate Genes Associated with Blister Rust Resistance in Whitebark Pine (Pinus albicaulis) Revealed through de novo Transcriptome Assembly and Differential Gene Expression Analysis

Creator:: Bair, Zolton J.
Abstract:: Whitebark pine (Pinus albicaulis) is an iconic North American high-elevation tree species currently threatened by climate change, mountain pine beetle, and white pine blister rust (WPBR), a lethal disease caused by the non-native fungal pathogen Cronartium ribicola. In collaboration with the USDA Forest Service Dorena Genetic Resource Center, germplasm was...

Field classification of white pine blister rust stem-cankers on resistant western white pine in northern Idaho and determination of respective tissue damage through tree ring analysis

Creator:: Eckert, Amy I.
Abstract:: Western white pine historically dominated northern Idaho’s forested landscape and was the Inland Empire’s most economically important tree. White pine blister rust, caused by the exotic fungus Cronartium ribicola, played a principal role in the decline of western white pine. The pathogen causes branch and bole cankers, which usually girdle...

On-farm inquiry and assessment of tillage and cover cropping for white mold control in snap bean production

Creator:: Harrison, Elizabeth Langham.
Abstract:: Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...

Studies on the etiology and epidemiology of bull's eye rot of pears

Creator:: Henriquez, Jose Luis, 1961-
Abstract:: The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Management of powder-post beetles, Dinoderus minutus F. in freshly cut bamboo

Creator:: Garcia, Carlos Manalo
Abstract:: The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and ftmgi associated with beetles were investigated. Finally, the...

Plant hormone-induced defense responses against Botrytis cinerea

Creator:: Akagi, Aya
Abstract:: Several plant hormones, including ethylene and jasmonates, are known to mediate responses against biotic and abiotic stress. The first and second objectives of this thesis were (i) to elucidate the role of ethylene in defense responses against Botrytis cinerea and specifically (ii) to determine the potential contribution of ethylene response...

Histological comparisons of needle tissues of four species of white pine infected by Cronartium ribicola

Creator:: Sweeney, Katarina
Abstract:: Hypersensitive response-like (HR-like) needle reactions to infection by the white pine blister rust pathogen, Cronartium ribicola, have been reported for several species of five needle pines native to western North America. The best-studied examples are in Pinus monticola and P. lambertiana. In these species a "needle spot" phenotype has been...
