Rangel, Juliana; Giresi, Melissa; Pinto, Maria Alice; Baum, Kristen A.; Rubink, William L.; Coulson, Robert N.; Johnston, John Spencer (Ecology and Evolution, 2016) -
Assessing the Potential Threat of Widely Used Agrochemicals to Honey Bee (Apis mellifera L.) Drones and Workers
Fisher II, Adrian Leon (2017-07-21)Honey bees (Apis mellifera) have been experiencing an ongoing decline in population over the last half century despite their tremendous importance to agriculture. A variety of environmental pressures have been implicated ... -
The Effects of Honey Bee (Apis mellifera) Queen Insemination Volume on Colony Growth
Payne, Alexandria N (2015-09-27)The honey bee (Apis mellifera) is a eusocial insect where each individual hive contains a single, polyandrous queen that is responsible for laying the fertilized eggs that maintain a hive’s worker population. Virgin queens ... -
An Empirically- and Theoretically-based Model of the Market for Pollination Services
Williamson, Kendra May (2016-12-05)Motivated by increasing threats to pollinator health and the resultant impacts on pollination fees, this thesis models the market for pollination and honey production using the most complete economic model of the joint ... -
Endopolyploidy Changes with Age-Related Polyethism in the Honey Bee, Apis mellifera
Rangel, Juliana; Strauss, Kim; Seedorf, Kaileah; Hjelmen, Carl E.; Johnston, J. Spencer (PLOS, 2015-04-16)Honey bees (Apis mellifera) exhibit age polyethism, whereby female workers assume increasingly complex colony tasks as they age. While changes in DNA methylation accompany age polyethism, other DNA modifications accompanying ... -
Evaluating Perennial and Annual Companion Plantings for Pollinator Enhancement of Yield in Small-Scale Vegetable Production
Montoya, John Edward (2018-08-23)Pollination is a key component to obtain proper yield and fruit set in numerous vegetable crops, with the honey bee, Apis mellifera, being their primary pollinator. Honey bee populations in the United States have ... -
Fate and Honey Bee Toxicity of Selected Public Health Insecticides
Anderson, Jenise Ruby (2016-04-12)Honey bees (Apis mellifera) are arguably the most important beneficial insect in agricultural and horticultural ecosystems in the United States. Despite their importance, honey bee populations have been negatively impacted ... -
Honey Bee (Apis mellifera) Queen Reproductive Potential Affects Queen Mandibular Gland Pheromone Composition and Worker Retinue Response

The Role of Gene Expression in Task Regulation of the Worker Caste of the Red Imported Fire Ant (Solenopsis Invicta, Buren)
Hawkings, Chloe Lauren (2018-12-04)The reproductive ground plan hypothesis suggests that the evolution of social insects has resulted in genes being co-opted from reproductive functions into functions that enable the division of labor. To test this hypothesis ... -
THE EFFECTS OF IN-HIVE PESTICIDE EXPOSURE DURING DEVELOPMENT ON HONEY BEE (APIS MELLIFERA L.) QUEEN REPRODUCTION, PHYSIOLOGY, AND WORKER BEHAVIOR
Walsh, Elizabeth M. (2019-11-22)Several factors are responsible for the health decline currently faced by managed honey bees (Apis mellifera) worldwide, including pests, pathogens, queen failure, pesticide contamination, habitat fragmentation and nutritional ...
