Effects of Pesticide Exposure on Honey Bee Health : Impacts of Pesticide Interactions and Exposure Through Multiple Routes

Creator:: Parreira, Stephanie
Abstract:: Honey bees (Apis mellifera) are responsible for approximately $17 billion in crop production per year in the United States, and are arguably the most important pollinators in the nation. The future of crop pollination and production is threatened by widespread national honey bee colony losses, which have averaged approximately 30%...

Colony Level Infection of Honey Bee Gut Pathogen, Nosema ceranae and Role of Pollen Nutrition in Nosema ceranae Infection and Bee Survival

Creator:: Jack, Cameron
Abstract:: Honey bees are important pollinators for many agricultural systems throughout the world. However, recent honey bee declines have caused great alarm, drawing attention to the vulnerability of worldwide agriculture to pollinator loss. These declines are often attributed to a combination of pests, pathogens, viruses, chemicals, and a lack of proper...

Improving Honey Bee Health: Evaluating Efficacy and Safety of Oxalic Acid Vaporization Tactic for Varroa destructor Control and Understanding Factors Triggering European Foulbrood Disease

Creator:: Bozkus, Mustafa
Abstract:: Honey bees are vital for our food production and ecosystem due to their critical pollination services. The beekeepers in the United States and worldwide have reported significant colony losses for over fifteen years. Several stressors are implicated in these colony declines, including parasites, diseases, poor nutrition, and pesticide exposure. There...

Consequences of coumaphos and Varroa destructor on drone honey bee sperm quantity

Creator:: Delaney, Deborah Anne
Abstract:: The number of drones and genetic diversity among drones are essential components to a well mated queen. Varroa destructor preferentially parasitizes drone brood, and is thought to be responsible for the loss of feral populations that once provided additional drones for honey bee mating areas. It is necessary to use...

Effects of pollen collected by honey bees from pollination dependent agricultural cropping systems on honey bee nutrition

Creator:: Topitzhofer, Ellen
Abstract:: Managed honey bee (Apis mellifera L.) colonies are important pollinators of many cultivated crops. Honey bee colony declines averaging 30% annually in the United States for the past 7 years have caused significant concern and hence have been a topic of intensive investigation. These declines are reportedly due to multiple...

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...

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...

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...

Bees Associated with Linden (Tilia spp.) Trees and their Susceptibility to Toxic Sugars in Nectar

Creator:: Argoti, Adriana G.
Abstract:: Bees provide critical pollination services to diverse agricultural crops, native plants and trees. Globally, there are reports of bee declines which have been attributed to diseases, exposure to pesticides and changes in land use that are believed to have led to a reduction in foraging resources and nesting habitats for...

A comparison of bumble bees (Bombus spp.) and honey bees (Apis mellifera) for the pollination of Oregon cranberries (Ericaceae: Vaccinium macrocarpon)

Creator:: Phillips, Kimberly N.
Abstract:: In cranberry (Vaccinium macrocarpon Aiton) cultivation, farmers typically rent colonies of honey bee (Apis mellifera) for pollination. However, the efficiency of this bee at pollinating cranberries in Oregon, as in other regions, is questionable. Bumble bees (Bombus sp.) are reportedly effective in other regions, but their impact in Oregon is...
