Available in PDF, EPUB and Kindle. Book excerpt: The Foraging Behavior of the Honeybee (Apis mellifera, L.) provides a scholarly resource for knowledge on the regulation, communication, resource allocation, learning and characteristics of honeybee foraging behavior at the individual and colony level. Foraging, in this context, is the exploration of the environment around a honey bee hive and the collection of resources (pollen, nectar, water, etc.) by bees in the worker caste of a colony. Honeybees have the unique ability to balance conflicting and changing resource needs in rapidly changing environments, thus their characterization as “superorganisms made up of individuals who act in the interest of the whole. This book explores the fascinating world of honey bees in their struggle to obtain food and resources in the ecosystem and environment around the hive. Written by a team of international experts on honey bee behavior and ecology, this book covers current and historical knowledge, research methods and modeling used in the field of study and includes estimates of key parameters of energy utilization, quantities of materials collected, and identifies inconsistencies or gaps in current knowledge in the field. Establishes a basis of current knowledge on honeybees to build and advance understanding of their foraging behavior Addresses stressors such as habitat loss, climate change, pesticides, pests and diseases Presents concise concepts that facilitate direct traceability to the original underlying research

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines three factors that may influence the change in protein content and size of the brood food glands in honey bees. Effects on the mandibular gland, involved in the production of brood food and in royal jelly, have not been examined in relation to primer pheromones while effects on the hypopharyngeal glands, also involved in the production of brood food, have not been examined in relation to queen mandibular pheromone. This thesis provides preliminary insight into how these pheromones affect the extractable protein content of brood food glands. The first study in this thesis assessed the effects of brood pheromone (BP), queen mandibular pheromone (QMP), and pollen presence on the protein content of hypopharyngeal and mandibular glands of the honey bee. In this study, newly emerged bees were caged for 12 days in one of eight treatments: Queenless state: 1) control (no pollen + no pheromone), 2) pollen, 3) BP, 4) BP + pollen; Queenright state: 1) QMP, 2) QMP + pollen, 3) BP + QMP, 4) BP + QMP + pollen. This study indicated that regardless of pheromone treatment, the most influential factor on gland protein content and size was pollen. The second experiment examined effects of varying pollen dilution on hypopharyngeal and mandibular gland protein content, bee mass, and lipid content of the honey bee. In this experiment, newly emerged bees were caged for 7 days and fed one of five treatments: pollen, 1:1 pollen: cellulose (vol:vol), 1:2 pollen: cellulose (vol:vol); 1:3 pollen: cellulose (vol:vol), and cellulose. This study indicated that bees on the pollen diet were significantly greater than all other diluted diets in measurements of hypopharyngeal gland protein content, lipid content, and mass with significantly less consumption. However, mandibular gland protein content of bees on the pollen diet was significantly greater only from pure cellulose.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: From prokaryotes to vertebrates, the use of chemical signals is widespread. However, the underlying mechanisms that have led to the diversification of chemical communication are poorly understood. Here, I focus on the pheromonal communication system of the honey bee, Apis mellifera, and describe some of the molecular and physiological mechanisms that underlie pheromone production and response in this species. The mandibular glands of queen honey bees produce a pheromone (QMP) which modulates many aspects of worker behavior and physiology, and is critical for colony social organization. Chapters 1 and 2 examine how the mating process in queens can produce changes in queen behavior, physiology, and pheromone production. Chapter 3 demonstrates that these changes in pheromone production appear to be linked to differences in ovary development, and that workers are most attracted to the pheromonal blend of queens with the most activated ovaries. Chapters 4 and 5 explore how variation in pheromone response can mediate queen-worker interactions. In chapter 4, I document extensive variation in worker attraction to QMP, show that this variation is linked to individual reproductive potential, and describe some of the molecular processes that are associated with this variation. Finally, in chapter 5, I test whether variation in a pheromone receptor for the main QMP component can explain the observed variation in worker attraction to the queen, and then take a molecular evolution approach to begin to elucidate the selection pressures acting on this receptor. In addition to the work presented in this dissertation, linkage mapping studies are currently underway to identify the genetic components underlying worker attraction to QMP as well as a set of behavioral and physiological manipulations to identify the epigenetic and environmental factors that can also contribute to this variation. The results of these studies demonstrate that the chemical communication system between honey.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines some important physiological and pheromonal factors regulating foraging and colony growth in honey bee colonies. The first study analyzed effects of soybean trypsin inhibitor (SBTI) on the development of hypopharyngeal gland, midgut enzyme activity and survival of the honey bee. In this study newly emerged caged bees were fed pollen diets containing three different concentrations of SBTI. Bees fed 1% SBTI had significantly reduced hypopharyngeal gland protein content. This study indicated that nurse bees fed a pollen diet containing at least 1% SBTI would be poor producers of larval food. In the second study nurse bee biosynthesis of brood food was manipulated using SBTI, and the resulting effects on pollen foraging were measured. Experimental colonies were given equal amounts of SBTI treated and untreated pollen. SBTI treatments had significantly lower hypopharyngeal gland protein content than controls. There was no significant difference in the ratio of pollen to non-pollen foragers and pollen load weights collected between the treatments. These results supported the pollen foraging effort predictions generated from the direct independent effects hypothesis. In the third study we tested whether brood pheromone (BP) regulated queen egg laying via modulation of worker-queen interactions and nurse bee rearing behaviors. This experiment had BP and control treatments. Queens in the BP treatment laid greater number of eggs, were fed for a greater amount of time and were less idle. Significantly more time was spent in cell cleaning by the bees in BP treatments. The results suggest that brood pheromone regulated queen egg-laying rate by modulating worker-queen interactions and nurse bee rearing behavior. The final study of this dissertation focused on how dose-dependent BP-mediated division of labor affected the partitioning of non-foraging and foraging work forces and the amount of brood reared. Triple cohort colonies were used and there were three treatments, Low BP, High BP and Control. Low BP treatments had significantly higher ratio of pollen to non-pollen foragers and greater pollen load weights. Low BP treatment bees foraged at a significantly younger age. This study has shown that BP elicits dose-dependent modulation of foraging and brood rearing behaviors.

Available in PDF, EPUB and Kindle. Book excerpt: Reproductive division of labour is a defining characteristic of eusocial insects. In honey bees, there is normally a single, highly fecund queen, responsible for producing all the brood in the colony. Workers are functionally sterile, developing their latent ovaries only upon queen loss. Workers cannot mate, and are only capable of laying unfertilised, male eggs. I investigated the effects of various chemical, genetic, and nutritional factors on the ovary development of honey bee workers. I demonstrate that queen mandibular pheromone inhibits worker ovary development in caged queenless workers to the same degree as queen extracts. Four newly identified queen pheromone components did not inhibit ovary development alone, nor did they increase the efficacy of the other components. Anarchistic bees are a line developed by recurrent selection in which workers commonly reproduce in queenright colonies. There was no difference between the ovary development of anarchistic or wild type workers in colonies headed by anarchistic or wild type queens, therefore queen type is not responsible for the phenomenon. Anarchistic workers perceive queen pheromones, and anarchistic queens produce an attractive blend, as I found no differences in the retinue response of either worker type to either queen type. There also was no difference in response to queen pheromones at a high dose. At lower doses, however, wild type workers were more inhibited by queen pheromones than were anarchistic workers. Both adult and larval diet influenced adult ovary development, but workers fed high quality diets as adults had higher levels of ovary development than those fed low quality diets as adults regardless of larval diet quality. Nutrition is likely responsible for the seasonal variation observed in ovary development. Disruptive selection resulted in lines of bees with high or low levels of ovary development. High ovary development colonies collected far more pollen than their low line counterparts. Cross-fostering workers from the high line into the low line and vice versa demonstrated that there is an effect of both genotype and rearing environment. These results demonstrate the complex interactions between nutrition, pheromones, genetics, and environment that determine worker reproductive potential.
