Tactics for enhancing conservation biological control of twospotted spider mites, Tetranychus urticae Koch, in Pacific Northwest hop yards

Creator:: Woods, Joanna L.
Abstract:: The twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a worldwide pest of numerous agronomic and horticultural plants. Conservation biological control of this pest can be unreliable due to asynchrony of natural enemies and certain horticultural practices that have a direct or indirect affect on natural enemies and the...

Effect of feeding various dosages of Saccharomyces cerevisiae fermentation product on health, reproduction, and costs in multiparous dairy cows

Creator:: Shriver-Munsch, Christine M.
Abstract:: The transition period is a time of increased nutritional demands and risk to metabolic and infectious diseases in dairy cows due to a suppressed immune system. These problems lead to reproductive challenges, increased culling rates, and decreased milk production postpartum, which leads to decreased profits. Feeding yeast (Saccharomyces cerevisiae) or...

Exploring How Alternatively Certified Agriculture Teachers Acquire Practices and Participate in a Community of Practice: A Hermeneutic Phenomenology

Creator:: Claflin, Kellie
Abstract:: The purpose of this hermeneutic phenomenological study was to explore the lived experience of alternatively certified agriculture teachers, acquire the practices of agriculture teachers, and participate in the agriculture teacher community of practice. The study was grounded in an interpretivist approach, which provided an alterantive perspective to the positistic-like research...

Mapping quantitative trait loci underlying genome-wide recombination rate and mating system differences in meadowfoam

Creator:: Kishore, Venkata Krishna
Abstract:: Meadowfoam (Limnanthes alba Bentham; Order: Brassicales; Family: Limnanthaceae) is a self-compatible, predominantly allogamous, insect pollinated species. Meadowfoam oil is a source of novel unsaturated very-long-chain (VLC) seed oils (C₂₀ and C₂₂) with low concentrations of saturated fatty acids (typically less than 2%) and outstanding oxidative stability. Here we report the...

Studies in cereal science : arabinoxylans, glutenins, and their interactions; determining optimum water addition in noodle doughs; and quality and nutritional traits in a hard x soft wheat cross

Creator:: Kongraksawech, Teepakorn
Abstract:: The major components of wheat flour are keys to its functionality in processing and product quality. The major components, other than the lipids, are polymers: starch, protein, and non-starchy polysaccharides (NSP). In wheat NSP are primarily arabinoxylans (AX). These components are compartmentalized in the grain but are forced into close...

Porcine zona pellucida immunocontraceptive vaccine for horses

Creator:: Bartell, Jennifer Ann
Abstract:: The Bureau of Land Management (BLM) maintains a growing number of feral horses on public rangelands. With population growth rates as high as 22% annually, herds are exceeding their carrying capacity and millions of dollars are spent maintaining captured horses in holding facilities awaiting adoption. To manage the feral horse...

The short term temporal and spatial variability of nitrogen and phosphorus in two Oregon Coast Range streams

Creator:: Scherer, Robert A.
Abstract:: High intensity sampling was undertaken to characterize the temporal and spatial variability of oxidized nitrogen (NO3-N + NO2-N), ammonia-nitrogen (NH3-N), total dissolved phosphorus, total unfiltered phosphorus and orthophosphorus (PO4-P) from two adjacent small streams in Western Oregon's Coast Range, Deer Creek (303 ha) and Flynn Creek (203 ha). Deer Creek...

Leadership, Mathematics, and Science Integration in Secondary Agricultural Education

Creator:: McKim, Aaron J.
Abstract:: Research exploring methods to improve student learning of leadership, mathematics, and science in the United States is critically important. In this study, I sought to delve into the potential for student learning of leadership, mathematics, and science within the context of school-based agricultural education. Recognizing the teacher as a gatekeeper...

Influence of temperature and photoperiod on the developmental biology of the obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera:Tortricidae)

Creator:: Ranga Rao, Gangavalli V.
Abstract:: Developmental thresholds and thermal unit (degree day) requirements for eggs, different larval instars, pupal stage and preoviposition period were determined for the obliquebanded leafroller (OBLR), Choristoneura rosaceana (Harris). Separate thresholds and degree day requirements were determined for males and females, but differences between the sexes were not significant. However, there...
