Evaluation of grapevine red blotch virus epidemiology with reference to potential insect vectors

Creator:: Dalton, Daniel T.
Abstract:: Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....

Raspberry viruses affect the behavior and performance of Amphorophora agathonica in single and mixed infections

Creator:: Lightle, Danielle and Lee, Jana
Abstract:: Pathogens may alter their hosts, which consequently increases transmission efficiency by vectors. We examined the effects of Raspberry leaf mottle virus [RLMV; Closterovirus (Closteroviridae)] and Raspberry latent virus [RpLV; Reovirus (Reoviridae)], alone and in a co-infection in raspberry, Rubus idaeus L. (Rosaceae) cv. Meeker, on the behavior and performance of...

Determining novel control methods for cabbage maggot (Delia radicum) in the Pacific Northwest

Creator:: Dugger, Chloe D.
Abstract:: Cabbage maggot, Delia radicum (Diptera: Anthomyiidae) impacts the production of Brassicaceae crops worldwide. The larva feed on the roots of crops causing reductions in yields due to impaired root function and unmarketability of crops. Chemical and cultural management programs are commonly used to control cabbage maggot with varying rates of...

Naphthalene resistance in a house fly strain : its inheritance and characteristics

Creator:: Schafer, James Arnold
Abstract:: A combination of genetical and biochemical methods were utilized in investigating house fly resistance to naphthalene. The inheritance of resistance was determined by crossing a naphthalene resistant strain of Musca domestica L. with a susceptible mutant marker strain. Biochemical comparisons were made on substrains isolated from the progeny of these...

Induction of microsomal oxidases by dieldrin in house flies

Creator:: Walker, Charles Robert
Abstract:: Previous investigations have shown that exposure to DDT results in increased activity in soluble and microsomal enzyme in insects. These responses in DDT-resistant Triatoma infestans nymphs and in adults of DDT-resistant Musca domestica (the common house fly) are accompanied by increased RNA and protein synthesis. The phenomenon has been termed...

Evaluating Drosophila suzukii immunomarking for mark-capture research

Creator:: Klick, Jimmy, Lee, Jana C., Hagler, James R., Bruck, Denny J., and Yang, Wei Q.
Abstract:: Drosophila suzukii Matsumura (Diptera: Drosophilidae) utilizes ‘Himalaya’ blackberry, Rubus armeniacus Focke (Rosaceae), as a host and may invade berry and stone fruit crops from field margins containing this invasive weed. Laboratory and semi-field studies were conducted to determine (1) the persistence of protein marks including 10% chicken egg whites (egg...

Graphical models for multivariate spatial data

Creator:: Irvine, Kathryn M.
Abstract:: In this thesis we focus on a graphical model for multivariate spatially correlated data--isomorphic chain graphs (ICG; Gitelman and Herlihy, 2007). We feel ICG allow flexibility for modeling spatial correlation and are intuitively appealing because each model has an associated graph that visually represents a complex multivariate system. We examine...

Production of microsclerotia of the fungal entomopathogen Lecanicillium lecanii (Hypocreales: Cordycipitaceae) as a biological control agent against soil-dwelling stages of Frankliniella occidentalis (Thysanoptera: Thripidae)

Creator:: Wang, Haihong, Lei, Zhongren, Reitz, Stuart, Li, Yinping, and Xu, Xuenong
Abstract:: Microsclerotia (MS) production by two isolates of Lecanicillium lecanii on various culture media is described, and the efficacy of MS against western flower thrips is evaluated. High concentrations of MS (2.9-3.1×10⁵•mL⁻¹) were produced in media with C: N ratios of 7.4:1 and 10.3:1 by isolate SN21. Bioassays using soil-incorporated MS...

Marking, movement, and management of Drosophila suzukii in Oregon berry crops

Creator:: Klick, Jimmy
Abstract:: Drosophila suzukii Matsumura (Diptera: Drosophilidae) are small invasive flies that in the past five years (2009-2014) invaded berry and stone fruit production regions in Europe and the Americas. Evolutionary adaptations, biological traits, and anthropogenic factors have contributed to its current status as a global pest. Females oviposit eggs into ripe...
