The effects of environmental factors on honey bee morbidity
… relationship between environmental factors and honey bee health. I have three primary objectives in conducting this research. First, I examine whether being located near neonicotinoid seed treated crops increases honey bee morbidity. Second, I examine if forage availability and weather affect …

Toxicogenomics of Apis Mellifera
… reported in this dissertation demonstrate that honey bee P450s associated with detoxification are few in number, that these P450s appear to have evolved to respond specifically to natural compounds encountered in the hive environment, and that honey bees have a limited capacity to metabolize …

HONEY BEES, BIODIVERSITY AND CLIMATE CHANGE
Honey bees (Apis mellifera) are vital pollinators for both natural ecosystems and agricultural productivity. However, their populations are threatened by factors such as habitat loss, pathogens, climate change, and the genetic risks associated with selective breeding. This thesis explores the …

Ameliorative effects of phytochemical ingestion on viral infection in honey bees
Honey bee viruses, capable of causing a wide variety of detrimental effects, are an important dimension of honey bee health management. To date, there are no effective treatments for viral infection in honey bees and management relies largely on controlling Varroa mites, a honey bee pest capable of …

Amelioration of acute and chronic toxicity of imidacloprid by dietary phytochemicals in honey bees (apis mellifera)
Honey bees (Apis mellifera) provide important pollination services to the U.S. agricultural enterprise, valued at more than $15 billion per year. However, colonies have been declining due to multiple stressors, including parasites, pests, diseases, pesticides, nutrition, and modern beekeeping …

Crops, pesticides, and honey bee disease
Honey bee colonies are an essential factor in American agriculture and of overall ecosystem health. The winter of 2006 marked an observation of large scale losses of managed honey bee colonies (vanEngelsdorp et al, 2009). Since then, there has been an average loss of 30% of colonies in beekeeping …

Behavioral and biochemical processing of natural and synthetic xenobiotics in the western honey bee apis mellifera
As a eusocial insect, Apis mellifera, the western honey bee, accomplishes many tasks, including acquisition of food, defense against enemies, and reproduction, through division of labor. In this dissertation, I examined whether honey bees also exploit division of labor in the detoxification of …

Drinking from the Magic Well: Studies on Honey Bee Foraging, Recruitment, and Sublethal Stress Responses using Waggle Dance Analysis
… our ecologically and economically critical honey bees by decreasing the availability of quality foraging resources. Importantly, waggle dance analysis provides a versatile and relatively cost-effective tool for investigating the obstacles that honey bees face, such as habitat loss, in our …

Wireless sensor networks, actuation, and signal processing for apiculture
… supply for Earth's growing human population. Honey bees are a vital part of the food chain as the most important pollinator for a wide range of crops. Protecting the honey bee population worldwide, and enabling them to maximise productivity, are important concerns. This research proposes a …
