Book Synopsis Status of Pollinators in North America by : National Research Council
Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis The Costs and Benefits of Resistance and Tolerance Behaviors Against Varroa Mite (Varroa Destructor Anderson and Trueman) in Honey Bee (Apis Mellifera L.). by : Rassol Bahreini

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managed honey bee colonies face severe winter losses in northern climates. In my studies, interactions between genotypes of bees (genetically selected stock and unselected stock) with different levels of resistance and tolerance to varroa mites were assessed under a variety of treatment combinations to quantify effects of queen pheromone, acaricide treatment, wintering method, ventilation condition and pathogen infection on the costs and benefits associated with mite removal and mite-tolerance behaviors. In most of the experiments, mite-resistance caused greater varroa mite mortality within selected stock relative to unselected stock. Artificial and natural sources of queen pheromone caused greater varroa mite mortality within honey bee colonies relative to queenless colonies. While mite resistance had significant benefits, I showed that when producers selected colonies containing some mite resistance traits, it was traits associated with mite-tolerance and not mite-resistance were maintained and contributed to wintering success. Tolerance was effective at two levels of mites as obtained by late autumn treatment of colonies with oxalic but treatment did not improve wintering performance of either stock. Selected stock showed greater colony size, survival and resulted in more viable colonies in spring in comparison to unselected stock with similar initial mite levels (0.16 mites per bee). Selected stock showed greater relative wintering success than unselected stock when wintered indoors than when wintered outdoors but indoor wintering improved colony survival in both stocks relative to outdoor wintering. Carbon dioxide level increased within the winter bee cluster when colonies were maintained under restricted-ventilation (mean 3.82±0.031%, range 0.43-8.44%) and restricted ventilation increased mite mortality by 138% relative to standard-ventilation (mean 1.29±0.031%, range 0.09-5.26%), but restricted-ventilation did not affect bee mortality in comparison to standard-ventilation. In a laboratory study, I showed that Nosema inoculation (with co-infections of N. ceranae and N. apis) suppressed the effectiveness of mite removal behavior within selected bees relative to unselected bees. N. ceranae was more abundant than N. apis. Bees with greater mite removal capacities had higher costs associated with varroa-resistance as indicated by greater bee mortality rates when inoculated with varroa but bee mortality was not affected in Nosema inoculated bees.
Book Synopsis Management of Varroa Destructor in Apis Mellifera Colonies by : Asha
Download or read book Management of Varroa Destructor in Apis Mellifera Colonies written by Asha and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Apiculture forms an essential and vital component of sustainable integrated rural development programme as it improves the economy of farmers by enhancing the productivity of agricultural crops and honey production. Despite its great potential, beekeeping industry is facing several constraints, which needs immediate attention. Among these, Varroa destructor Anderson and Trueman, an ectoparasitic mite of brood and adult bees, is a serious pest of Apis mellifera L.). In the last three years, beekeeping in India is adversely affected by this mite. In the present scenario, 90 per cent apiaries and 50 per cent colonies are affected by this mite. Varroa was first described on its native host, the Asian honey bee (Apis cerana Fab.) in 1904 in Java (Oudemans, 1904). Some of behavioural traits which were acquired by honey bees against Varroa are tendency to swarm and willingness to abandon their hives may have effectively countered the mite, but these traits also suggested difficulty in domestication of this species.Genus Varroa consists of at least four but possibly seven distinct species. Among the four recognized species, the most destructive and largest among these is Varroa destructor.

Download or read book Modified Drone-Brood Removal to Control Varroa Destructor in Apis Mellifera Colonies written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The parasitic mite Varroa destructor Anderson and Trueman (Acari: Varroidae) has plagued European honey bees (Apis mellifera L.) in the Americas since its introduction to the United States in the 1980s. For many years, these mites were sufficiently controlled using synthetic acaricides. Recently, however, beekeepers have experienced increased resistance by mites to chemical pesticides, which are also known to leave residues in hive products such as wax and honey. Thus, there has been increased emphasis on non-chemical IPM control tactics for Varroa. Because mites preferentially reproduce in drone brood (pupal male bees), we developed a treatment strategy focusing on salvaging parasitized drones and removing mites from them. In our initial study, we tested 10 colonies of honey bees in each of four treatment groups: 1) negative control (no treatment); 2) positive control (treatment with fluvalinate); 3) periodic drone-brood removal and freezing; and 4) periodic drone-brood removal and return of adult drones to colony after physically removing any mites. We found that there were no significant differences measured between the mean mite levels of the treatment groups (P> 0.05). However, there were numeric trends indicating that both drone-brood removal groups were intermediate in mite levels compared to the negative and positive controls. In a subsequent study, we removed drone brood from colonies in which there is no acaricidal application and banking it in separate ÃØâ'ƠÅ"sacrificialÃØâ'ƠÂ colonies treated with pesticides to kill mites emerging with drones. We tested 20 colonies divided into three treatment groups: 1) negative control (no mite treatment); 2) positive control (treatment with fluvalinate and thymol); and 3) drone-brood trapping. Two colonies were selected from the drone-brood trapping group to serve as sacrificial colonies. We found that drone-brood trapping significantly lowered mite numbers during the early months of the season, eliminating the need f.

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.

Book Synopsis Asian Beekeeping in the 21st Century by : Panuwan Chantawannakul
Download or read book Asian Beekeeping in the 21st Century written by Panuwan Chantawannakul and published by Springer. This book was released on 2018-06-01 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the perspective of local scientists, this book provides insight into bees and bee management of Asia, with a special focus on honey bees. Asia is home to at least nine honey bee species, including the introduced European honey bee, Apis mellifera. Although A. mellifera and the native Asian honey bee, Apis cerana, are the most commonly employed species for commercial beekeeping, the remaining non-managed native honey bee species have important ecological and economic roles on the continent. Species distributions of most honey bee species overlap in Southeast Asia, thus promoting the potential for interspecies transmission of pests and parasites, as well as their spread to other parts of the world by human translocation. Losses of managed A. mellifera colonies is of great concern around the world, including in Asia. Such global colony losses are believed to be caused, in part, by pests and parasites originating from Asia such as the mite Varroa destructor, the microsporidian Nosema ceranae, and several bee viruses. Taking advantage of the experience of leading regional bee researchers, this book provides insight into the current situation of bees and bee management in Asia. Recent introductions of honey bee parasites of Asian origin to other parts of the world ensures that the contents of this book are broadly relevant to bee scientists, researchers, government offi cials, and the general public around the world.

Download or read book Industrial Entomology written by Omkar and published by Springer. This book was released on 2017-02-13 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of writings focused on conventional and unconventional insect products. Some of these products are commercials successes, while others are waiting to be launched and are the potential produce of the future. In addition to the well known products honey, mulberry silk, and lac, the book primarily concentrates on silk producing insects other than the mulberry silkworm, insects as food, as sources of medicines, pest and weed managers, and as pollinators. The book highlights the all pervasive role of insects in improving human lives at multiple levels. Accordingly, while most books on insects concentrate on how to limit growth in their population, it instead focuses on how to propagate them. In each chapter, the book brings to the fore how insects are far more beneficial to us than their well publicised harmful roles. This book approaches both unconventional and conventional insect products, such as honey, silk and lac in much more depth than the available literature. It investigates different aspects of the production of these insects, such as the related processes, problems and utilities, in dedicated chapters. Because this book deals with the production of insects or their produce, it has been named Industrial Entomology, perhaps the only book that truly reveals the tremendous potential of insects to help humans live better lives. Based on the research and working experience of the contributors, who are global experts in their respective fields, it provides authentic, authoritative and updated information on these topics. The book offers a unique guide for students, teachers, policy planners, small scale industrialists, and government ministries of agriculture and industry across the globe. It will provide a much required stimulus to insect appreciation and generate enthusiasm for research and the broader acceptance for insect produce. Hopefully, it will also present the Indian perspective on these topics to a global readership.
Book Synopsis The Role of Social Immunity in Feral Honey Bees (Apis Mellifera) in Response to the Parasitic Mite (Varroa Destructor) by : Brandon Mukogawa
Download or read book The Role of Social Immunity in Feral Honey Bees (Apis Mellifera) in Response to the Parasitic Mite (Varroa Destructor) written by Brandon Mukogawa and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Varroa destructor is a parasitic mite that threatens managed and feral Apis mellifera colonies worldwide. Managed honey bees are regularly treated with miticides to control for Varroa, but the use of these chemicals reduces bee fitness and leads to the evolution of miticide resistance in V. destructor. However, feral colonies, which tend to be more Africanized, may tolerate mites without chemical treatment. Some studies have shown Africanized colonies demonstrate increased hygienic behavior by removing more dead brood and by grooming more intensely, making them potentially more Varroa-resistant. Thus, comparing the behavior of feral and managed bees can reveal the potential role of social immunity in feral bee tolerance against V. destructor. These findings can better inform traits of interest for bee breeding programs. Interestingly, no differences in mite infestation were observed despite that managed bees were treated with miticides at multiple times throughout the year. This result suggests that feral colonies have ways to reduce their mite levels. There were no observed differences in the social immunity of feral and managed honey bees as measured by their hygienic, self-grooming, or mite biting behavior. However, we provide the first evidence that both feral and managed honey bees bite off mite forelegs at higher rates than other legs; mite forelegs contain chemosensory organs that mites use to find brood cells to reproduce in. Such biting may therefore impair mite reproduction. Future studies should therefore focus on other mechanisms that evidently allow feral bees to resist Varroa infestation.
