Inferring rare bumble bee species occurrences from nontarget bumble bee assemblages
… the success of wild plant communities. Bumble bees are some of the most effective pollinators in temperate climates thanks to their cold hardiness, ability to buzz pollinate, and generalist foraging tendencies, but many species are experiencing sharp declines. The endangered rusty patched …

Landscape and design influence bee and parasite communities in garden bee hotels
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-20 without embargo terms

Wild bee responses to land use change: investigating the role of bee body size
… to sustain species and populations. Wild bees (Hymenoptera: Apoidea) are essential pollinators for many wild and cultivated flowering plants, and exhibit marked differences in life history traits. The consequences of land use change may therefore affect wild bees differently, but this …

Aspects of Foraging in Bees: Apple Pollination, Native Bee Populations, and Honey Bee Communication
Bees are well known for their ability to pollinate a diverse range of plants. In the process of gathering food (pollen and nectar), bees transfer pollen from one flower to another, facilitating reproduction. I investigate two important aspects of foraging: pollination of an important crop by native …

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 …

Chemical Manipulation of Honey Bee Behavior
The loss of managed honey bee colonies, resulting from their unintentional exposure to pesticides, is a topic of concern for the agricultural and apicultural industry. Current methods for reducing pesticide exposure to bees involve the application of pesticides before crop bloom or in the evening …

NEONICOTINOID TOXICITY IN REPRODUCTIVE HONEY BEE CASTES
High pollinator losses of recent decades have been attributed to several causes including increased exposure to pesticides, particularly neonicotinoid insecticides. This has spiked re-evaluation of neonicotinoid use in agriculture and has heightened the need to enhance pesticide risk assessment. …

Honey Bee Communication: The Dance-Language Controversy
… recent years, the evidence suggesting that honey bees communicate with a "dance language" has been strongly attacked on both theoretical and experimental grounds. The controversy is reviewed and the main issues are isolated and discussed. The fundamental obstacle to the resolution of this …

The Characterisation Of Bee Nicotinic Acetylcholine Receptors
… a matter of considerable interest. Localised bee colony losses and losses of wild bee numbers are believed to be related to the use of these insecticides, resulting in a European ban on three commercially important compounds. As it stands, the model insect Apis mellifera is used for most …

Neurogenomic architecture of honey bee social behavior
… and social organization in the western honey bee (Apis mellifera). This dissertation consists of original research on the neurogenomic architecture of social behavior in honey bees. Honey bees form highly complex societies and exhibit rich behavioral repertoires generated by a tiny brain of …

Honey Bee (Apis Mellifera) Foraging Preferences are Negatively Correlated with Alfalfa Leafcutting Bee (Megachile Rotundata) Productivity in Virginian Landscapes
Honey bees (Apis mellifera) may serve as bioindicators of habitat quality for themselves and also other insect pollinators because we can observe, decode, map, and analyze the information encoded in the waggle dance communication behavior, which allows us to know where and when bees are collecting …

The Ogbanje in Little Bee by Chris Cleave
<p>"In Chris Cleave's 2008 novel Little Bee, he offers readers a literary representation of the Nigerian spirit-child for the purpose of political and post-colonial examination. Cleave's intentions are revealed through a full study of this traditional Nigerian concept. The Nigerian spirit-child, …

Essays on the economics of bee-friendly beef
The decline in bee populations, driven by biodiversity loss, poses a major threat to food production systems, as many wild plants and agricultural crops rely on bee pollination services. Addressing this issue requires coordinated efforts from producers, retailers, and consumers to restore …

Digital Filter Design Using Improved Artificial Bee Colony Algorithms
… and slower convergence rate. The artificial bee colony (ABC) algorithm is a swarm-based search meta-heuristic algorithm inspired by the foraging behaviors of honey bee colonies, with the benefit of a relatively fewer control parameters. In its original form, the ABC algorithm has certain …

Sublethal Effects of Pesticides on Visually-Guided Bee Behaviours
European honeybees (Apis mellifera) are abundant and effective natural pollinators contributing enormously to mass production of agricultural crops through extensive foraging. They possess visual systems that are highly sensitive to motion and rely on motion of visual elements (optic flow) to …

The Opsins and Nuclear Receptors of the Honey Bee
… the value of the recently sequenced honey bee genuine for the expansion of our knowledge of insect evolution and physiology. In the first study, a novel lineage of insect opsins is described based on the identification of a novel opsin gene, pteropsin, in the honey bee. This novel lineage …

Honey bee habitat at the University of Illinois campus
There has been a decrease in the numbers of pollinators, and pollinator refuges are needed to confront risks associated with the effects brought about by the pollinator shortage. This research studies the potential of using current No-Mow Zones and prairie zones at the University of Illinois as …

The effects of environmental factors on honey bee morbidity
… 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 honey …
