Book Description
Pollinators are integral to modern agricultural productivity and the continued survival and vitality of natural ecosystems. However, recent declines in pollinator populations and species diversity threaten both food security and the architecture of natural habitats. Due to their vital role in agriculture, honey bees (Apis mellifera) have served as a model organism for investigating the alarming and widespread diminution of pollinator populations. Indeed, surveys from both North America and Europe report large annual colony losses. Parasites along with chemical exposure, poor nutrition, climate change and habitat destruction are frequently cited as leading causes of colony loss. Honey bee colonies are assaulted by a battery of bacterial, fungal and viral pathogens in addition to other parasitic arthropods including mites and beetles. Novel, cost-effective disease management practices are desperately needed to preserve colony health. Basic studies investigating honey bee immunity and disease pathology lay the groundwork for developing efficacious diagnostic tools and treatments. Here, we present a series of studies characterizing honey bee immunity and the molecular, physiological and behavioral responses of honey bees to two important fungal pathogens, Nosema apis and Nosema ceranae. Chapter 1 reviews the current state of research on these prevalent and destructive disease agents and highlights future studies that are needed to develop effective management practices. Chapter 2 investigates worker honey bee genomic responses to general immune stimulation. Findings from these experiments provide a contextual framework for Chapter 3's studies, which characterize worker honey bee genomic responses to infection with Nosema parasites and offer a molecular model for explaining previously documented disease symptoms. Chapter 4 investigates drone (male) honey bee molecular, physiological and behavioral responses to Nosema infection and underscores potential caste-specific responses to infection that have larger implications for colony fitness. Finally, Chapter 5 summarizes novel findings from this dissertation, integrates results with current scientific literature and discusses the future of Nosema management.

Book Description
Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Book Description
Herbal therapy, holistic treatments and aromatherapy are some of the oldest known medical remedies in the world - and so is Apitherapy, yet this universally available and effective ancient therapy is often overlooked. What is Apitherapy and why haven't you heard of it? You probably have, just not by its accepted and medicinal name. Apitherapy is the use of products derived from Honey Bees, this includes Royal Jelly, Honey, pollen, bees wax and even venom. Author Paul Enders details not only the vast and intricate history of Apitherapy, but its modern uses - and how it can be used to help you today. Learn how the many different products created by Bees can help treat different conditions and offer many different benefits, including: * Helps fight against pathogenic microorganisms * Improve appetite and the digestive system * Improve metabolism of human tissues * Reduce fat accumulation * Pollen has a radioprotective and anti-tumor effect * Regulates bowel function in constipation * And much, much more! Apitherapy has been around as long as we've had bees, it is a vast science of information, treatments and benefits, ones that can help you today and for everyday to come.

Book Description
"Honey bees (Apis mellifera) are major pollinators of many food crops, but unfortunately, population declines are threatening global food security and ecosystem health. Honey bees are under multiple stressors, such as poor nutrition, parasitic mites, and pathogens. Similar to human health, the gut microbiome of the honey bee is hypothesized to affect bee's overall health by supporting host metabolism and immune system. However, it's not clear how stressors impact gut microbiome, and thus health, of bees. Nutritional supplementation could mitigate negative effects of stressors, particularly for bees that don't have access to diverse floral resources. In this study, I conducted a one-year field experiment on 16 honey bee hives at two locations in eastern Washington to evaluate how nutritional supplementation impacts gut bacterial community structure and function, disease occurrence, and overall colony health. The supplementation was mixed in 1:1 sugar-water and mimicked nectar and pollen, consisting of protein, vitamins, and minerals. Control hives were fed 1:1 sugar-water only. To assess gut bacterial community structure before, during, and after feeding treatments, I used 16S rRNA gene amplicon sequencing on the Illumina MiSeq using primers 515F+barcode and 926R. The bioinformatic programs Quantitative Insights into Microbial Ecology (QIIME) and Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) were used to analyze how nutritional supplementation affected gut microbiome community structure and predicted function, respectively. Additionally, hives were weighed routinely to determine colony growth/productivity. For a subset of timepoints, I screened for Varroa mites and microsporidian pathogen Nosema. While supplemental nutrition did not have an overall impact on hive health or gut microbiome, the gut microbiome present at the beginning of experiment correlated with hive survival, suggesting presence/abundance of bacteria present before hives established may have a long-term impact on surviving stressors (i.e. overwintering). Additionally, the gut microbiome was significantly different between hives that survived and those that died at the timepoint before death, further suggesting the microbiome may play a role in hive survival. With further exploration of bacteria associated with survival (i.e. knockout or inoculation study), a probiotic mixture could be developed and examined for positive influence over hive survival"--Pages iii-iv.

Book Description
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Book Description
This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.
