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...

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...

Environmental impacts on native bumble bee pollinators in an agricultural landscape of western Oregon

Creator:: Skyrm, Kimberly M.
Abstract:: Bumble bees provide vital pollination services in both native and agricultural landscapes. However, in recent years, bumble bee populations have experienced global population declines. The primary causes of these declines have been attributed to the environmental impacts of pathogens, pesticide use and habitat fragmentation. While research has examined the impacts...

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...

Potential impacts of canola (Brassica napus L.) on vegetable seed production in the Willamette Valley of Oregon

Creator:: Quinn, Michael P.
Abstract:: In the Willamette Valley of Oregon, a combination of the need for rotational crops and an increased desire for biofuel production created interest in planting Brassica napus (canola). However, questions were raised arisen over the potential damage canola production could have on the preexisting Brassica vegetable seed industry. To address...

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...
