This book was released on 2017 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The health and viability of colonies of the honey bee, Apis mellifera, in the United States have fluctuated dramatically over the past decade. This poses a substantial threat to agricultural production in this country. Currently, no single factor has been identified for this decline. Rather, it has been suggested that the interaction between multiple biotic and abiotic stressors may be responsible. Among these factors are pesticides, habitat loss, climate and weather, parasites and pathogens, and colony management techniques. For this reason, it is important to examine the prevalence of honey bee parasite and pathogen infection at the state level in comparison to national survey data. In the research described herein, molecular diagnostics were performed on worker honey bee samples from Arkansas hobbyist beekeepers and Oklahoma migratory beekeepers to detect the presence of the following A. mellifera pathogens and parasites: protozoans Nosema apis and N. ceranae; bacterial pathogens Spiroplasma apis and S. melliferum; Trypanosomatid parasites Crithidia mellificae and Lotmaria passim and the parasitic phorid fly Apocephalus borealis. A study including both migratory honey bee colonies and hobbyist managed colonies provides a more comprehensive distribution of where these parasite and pathogen species are occurring and potentially why they are occurring. The study determined that N. ceranae (H=11.6%, M=27.6), L. passim (H=11.3%, M=1.1%), and V. destructor (H=45.5%, M=17.2%), occur in both hobbyist and migratory managed colonies. Nosema ceranae was more prevalent in the migratory colonies than the hobbyist colonies. Spiroplasma was also detected in the Oklahoma migratory colony samples (8.05%), but not in the Arkansas hobbyist colonies. Both V. destructor and L. passim were more prevalent in the hobbyist managed colonies. This research resulted in the first detection of Lotmaria passim in Arkansas honey bees, as well as the first documented detection of L. passim and S. melliferum in Oklahoma. Apocephalus borealis, C. mellificae, N. apis, and S. apis were not detected in either the migratory nor the hobbyist colonies. This study compares honey bee management practices at the hobbyist and migratory level to better understand how management influences parasite and pathogen spread and abundance. The use of state-level surveys, when examining parasite and pathogen occurrence, allows for a better understanding of how these pests are spreading, as well as how quickly and by what means.

Download or read book Edible Insects written by Arnold van Huis and published by Bright Sparks. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
Book Synopsis Pollinators and Pollination by : Jeff Ollerton
Download or read book Pollinators and Pollination written by Jeff Ollerton and published by Pelagic Publishing Ltd. This book was released on 2021-01-18 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.

Download or read book Good beekeeping practices for sustainable apiculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-09-21 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bees provide a critical link in the maintenance of ecosystems, pollination. They play a major role in maintaining biodiversity, ensuring the survival of many plants, enhancing forest regeneration, providing sustainability and adaptation to climate change and improving the quality and quantity of agricultural production systems. In fact, close to 75 percent of the world’s crops that produce fruits and seeds for human consumption depend, at least in part, on pollinators for sustained production, yield and quality. Beekeeping, also called apiculture, refers to all activities concerned with the practical management of social bee species. These guidelines aim to provide useful information and suggestions for a sustainable management of bees around the world, which can then be applied to project development and implementation.

Download or read book Biogeography and Taxonomy of Honeybees written by Friedrich Ruttner and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honeybees are as small as flies or as large as hornets, nesting in nar row cavities of trees and rocks or in the open on large limbs of trees 30 m above ground. They occur in tropical zones and in the forests of the Ural mountains, they survive seven months of winter and even longer periods of drought and heat. Historically, they lived through a extended time of stagnation in the tropics from the mid-Tertiary, but then experienced an explosive evolution during the Pleistocene, re sulting in the conquest of huge new territories and the origin of two dozen subspecies in Apis mellifera. This vast geographic and ecologic diversification of the genus Apis was accompanied by a rich morphological variation, less on the level of species than at the lowest rank, the subspecies level. Variation being exclusively of a quantitative kind at this first step of speciation, tradi tional descriptive methods of systematics proved to be unsatisfactory, and honeybee taxonomy finally ended up in a confusing multitude of inadequately described units. Effective methods of morphometric-sta tistical analysis of honeybee popUlations, centered on limited areas, have been developed during the last decades. Only the numerical characterization of the populations, together with the description of behavior, shows the true geographic variability and will end current generalizations and convenient stereotypes.

Book Synopsis Beekeeping for Poverty Alleviation and Livelihood Security by : Rakesh Kumar Gupta
Download or read book Beekeeping for Poverty Alleviation and Livelihood Security written by Rakesh Kumar Gupta and published by Springer. This book was released on 2016-09-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Book intends to address all aspects needed to develop beekeeping into a powerful instrument of rural development and will focus on beekeeping as a tool for Poverty Alleviation and Livelihood security. In the backdrop of the social and economic issues of the people living in poverty region, the book aims to delineate specific motivation approaches to engage them in beekeeping and will serve as a guide for effective marketing through diversification and value addition of bee products. Nevertheless, marketing and environmental issues will remain an important component of this book. The aim is also to focus on indirect benefit of beekeeping so that it is integrated with farming and nature conservation. Other topics include ensuring the provision of practical techniques in handling and management of bees. It will provide detailed information on good contacts with policymakers and authorities; and channels for attracting finance especially in the third world countries. An interdisciplinary approach is the key feature of the book and it will also focus on few case histories and success stories to encourage the reader to take up beekeeping as a new venture gradually in a phased manner like traditional-transitional and modernised beekeeping. With the publication of this book, we hope to hand out a practical guide that will assist all those who are involved in beekeeping for development. We hope it will stimulate beekeeping as an integrated activity with farming and nature conservation and will serve in many households for poverty alleviation and livelihood security.

Download or read book The State of the World's Biodiversity for Food and Agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-03-12 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The State of the World's Biodiversity for Food and Agriculture presents the first global assessment of biodiversity for food and agriculture worldwide. Biodiversity for food and agriculture is the diversity of plants, animals and micro-organisms at genetic, species and ecosystem levels, present in and around crop, livestock, forest and aquatic production systems. It is essential to the structure, functions and processes of these systems, to livelihoods and food security, and to the supply of a wide range of ecosystem services. It has been managed or influenced by farmers, livestock keepers, forest dwellers, fish farmers and fisherfolk for hundreds of generations. Prepared through a participatory, country-driven process, the report draws on information from 91 country reports to provide a description of the roles and importance of biodiversity for food and agriculture, the drivers of change affecting it and its current status and trends. It describes the state of efforts to promote the sustainable use and conservation of biodiversity for food and agriculture, including through the development of supporting policies, legal frameworks, institutions and capacities. It concludes with a discussion of needs and challenges in the future management of biodiversity for food and agriculture. The report complements other global assessments prepared under the auspices of the Commission on Genetic Resources for Food and Agriculture, which have focused on the state of genetic resources within particular sectors of food and agriculture.

Book Synopsis The Forgotten Pollinators by : Stephen L. Buchmann
Download or read book The Forgotten Pollinators written by Stephen L. Buchmann and published by Island Press. This book was released on 2012-06-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consider this: Without interaction between animals and flowering plants, the seeds and fruits that make up nearly eighty percent of the human diet would not exist. In The Forgotten Pollinators, Stephen L. Buchmann, one of the world's leading authorities on bees and pollination, and Gary Paul Nabhan, award-winning writer and renowned crop ecologist, explore the vital but little-appreciated relationship between plants and the animals they depend on for reproduction -- bees, beetles, butterflies, hummingbirds, moths, bats, and countless other animals, some widely recognized and other almost unknown. Scenes from around the globe -- examining island flora and fauna on the Galapagos, counting bees in the Panamanian rain forest, witnessing an ancient honey-hunting ritual in Malaysia -- bring to life the hidden relationships between plants and animals, and demonstrate the ways in which human society affects and is affected by those relationships. Buchmann and Nabhan combine vignettes from the field with expository discussions of ecology, botany, and crop science to present a lively and fascinating account of the ecological and cultural context of plant-pollinator relationships. More than any other natural process, plant-pollinator relationships offer vivid examples of the connections between endangered species and threatened habitats. The authors explain how human-induced changes in pollinator populations -- caused by overuse of chemical pesticides, unbridled development, and conversion of natural areas into monocultural cropland-can have a ripple effect on disparate species, ultimately leading to a "cascade of linked extinctions."
