Physiological effects of non-nutritive sugars on the survivorship and fecundity of Drosophila suzukii (Diptera: Drosophilidae)

Creator:: Tang, Siew Bee
Abstract:: Spotted wing drosophila (SWD), Drosophila suzukii, is an economically damaging pest on small fruits. The estimated economic impact is hundreds of millions of dollars annually in the U.S. alone, and increasing every year. Current control of SWD relies heavily on chemical insecticides which have many negative impacts on environmental and...

Evaluating the Potential of Protein Supplements and Probiotics for Improving Honey Bee Health and Understanding Honey Bee Behaviors Related to Social Immunity

Creator:: Chapkin, Elissa R.
Abstract:: Managed honey bees (Apis mellifera) play a vital role in pollinating cultivated crops worldwide. Honey bee colony declines reported in the past two decades have been associated with stressors such as pests and diseases, pesticide exposure, and poor nutrition. In the wake of these colony declines, beekeepers have strived to...

One methodology for the incorporation of entomological material in the discipline of historic archaeology using the honey bee (Apis mellifera L.) as a test subject

Creator:: Kellar, Brenda M.
Abstract:: Using the honey bee (Apis mellifera L.) this thesis shows that entomological information and material can be retrieved using current historical archaeological methods. Historical archaeology has the ability to uncover connections between arenas as varied, and seemingly isolated, as the honey bee, the environment, and human cultures. By focusing on...

Using DNA Metabarcoding to Study Interactions Between Native Bees and Plants: Technical Developments and Applications

Creator:: Arstingstall, Katherine A.
Abstract:: Pollination is an essential ecosystem service that sustains functioning ecosystems and aids in food production. In response to recent, widespread declines of managed and native bee populations, many land managers have shown interest in developing conservation and restoration plans for enhancing native bee habitat. However, there is a lack of...

Natural enemies of native bumble bees (Hymenoptera: Apidae) in western Oregon

Creator:: Maxfield-Taylor, Sarah A.
Abstract:: Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in...

Impacts of Range Management Decisions on Native Pollinators: Innovative Grazing Practices and Riparian Restoration

Creator:: Mitchell, Scott R.
Abstract:: Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....

Effect of livestock grazing on native bees in a Pacific Northwest bunchgrass prairie

Creator:: Kimoto, Chiho
Abstract:: Native bees play an important role as pollinators of natural vegetation and agricultural crops. Yet many pollinators, including some native bees, are declining in numbers. Some of the potential causes of these declines are habitat destruction and degradation by various human land uses, including urban development and sprawl, construction of...

Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

Creator:: Yang, Ping
Abstract:: Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

Non-nutritive Sugars as a Management Tactic for Spotted-Wing Drosophila (Drosophila suzukii) and Non-Target Effects

Creator:: Price, Briana E.
Abstract:: With confirmation of non-nutritive sugar, erythritol, having insecticidal properties to Dipterans, this thesis research focuses on use of erythritol as a human-safe management tool for small berry and cherry pest, Drosophila suzukii, commonly referred to as spotted-wing drosophila. Drosophila suzukii is a destructive invasive fruit fly from Asia with an...

Characterization of organic light-emitting devices

Creator:: Norris, Benjamin J.
Abstract:: In this thesis steady-state (i.e. steady-state with respect to the applied voltage waveform) transient current-transient voltage [i(t)-v(t)], transient brightness-transient current [b(t)-i(t)], transient brightness-transient voltage [b(t)-v(t)], transient current [i(t)], transient brightness [b(t)], and detrapped charge analysis are introduced as novel organic light emitting device (OLED) characterization methods. These analysis methods involve...
