Book Description
Starting in late 2006, commercial migratory bee-keepers along the East Coast of the United States began reporting sharp declines in their honey bee colonies. Because of the severity and unusual circumstances of these colony declines, scientists named this phenomenon colony collapse disorder (CCD). Reports indicate that bee-keepers in most states have been affected. Overall, the number of managed honey bee colonies dropped an estimated 35.8% and 31.8% in the winters of 20062008, and 28.6% in 2009. To date, the precise reasons for colony losses are not yet known. Honey bees are the most economically valuable pollinators of agricultural crops world-wide. Scientists at universities and the USDA frequently assert that bee pollination is involved in about one-third of the U.S. diet, and contributes to the production of a wide range of fruits, vegetables, tree nuts, forage crops, some field crops, and other specialty crops. The monetary value of honey bees as commercial pollinators in the U.S. is estimated at $1520 billion annually. This book provides an overview of the importance of honey bee pollination to U.S. agricultural production and the extent and symptoms of CCD and how it differs from previous honey bee colony losses.Also discussed are the policy options and actions that Congress has taken to address this issues.

Book Description
In 2006, commercial migratory beekeepers along the East Coast of the United States began reporting sharp declines in their honey bee colonies. Because of the severity and unusual circumstances of these colony declines, scientists have named this phenomenon Colony Collapse Disorder (CCD). Reports indicate that beekeepers in 35 states have been affected. Overall, bee colony losses averaged about 30% in 2007. Reports for 2008 show continued declines with estimated average annual losses nation-wide approaching 35%. Honey bees are the most economically valuable pollinators of agricultural crops world-wide. Many scientists at universities and the U.S. Department of Agriculture (USDA) frequently assert that bee pollination is involved in about one-third of the U.S. diet, and contributes to the production of a wide range of fruits, vegetables, tree nuts, forage crops, some field crops, and other speciality crops. The monetary value of honey bees as commercial pollinators in the United States is estimated at about $15 billion annually. Honey bee colony losses are not uncommon. However, current losses seem to differ from past situations in that colony losses are occurring mostly because bees are failing to return to the hive (which is largely uncharacteristic of bee behaviour); bee colony losses have been rapid; colony losses are occurring in large numbers; and the reason(s) for these losses remains largely unknown. The potential causes of CCD, as reported by the scientists who are researching this phenomenon, include but may not be limited to parasites, mites, and disease loads in the bees and brood; emergence of new or newly more virulent pathogens; poor nutrition among adult bees; lack of genetic diversity and lineage of bees; level of stress in adult bees (e.g., transportation and confinement of bees, overcrowding, or other environmental or biological stressors); chemical residue/contamination in the wax, food stores, and/or bees; a combination of these and/or other factors. In 2007, the House held two subcommittee hearings to review the recent honey bee colony declines and to address concerns about pollinator health. In 2008, the Senate hosted a briefing on pollinators and their role in agricultural security. Various policy options were discussed at these hearings and briefings, including increasing federal funding for research and monitoring, providing technical support and assistance for beekeepers, and emphasising the importance of pollinator diversity and sustaining wild and native pollinator species.

Book Description
This book summarizes the current progress of bee researchers investigating the status of honey bees and possible reasons for their decline, providing a basis for establishing management methods that maintain colony health. Integrating discussion of Colony Collapse Disorder, the chapters provide information on the new microsporidian Nosema ceranae pathogens, the current status of the parasitic bee mites, updates on bee viruses, and the effects these problems are having on our important bee pollinators. The text also presents methods for diagnosing diseases and includes color illustrations and tables.

Book Description
From the Publisher: A century after the birth of Rachel Carson, the world faces a new environmental disaster, from a chemical similar to DDT. This time the culprit appears to be IMD, or imidacloprid, a relatively new but widely used insecticide in the United States. Many beekeepers and researchers blame IMD for Colony Collapse Disorder, which has wiped out 23% of America's beehives. Even trace amounts make bees unable to fly back to their hive. Since honeybees are essential to the production of most major food crops, their demise could spell catastrophe. In a riveting, scientific/political detective story, Michael Schacker examines the evidence and offers a plan to save the bees. Like An Inconvenient Truth and Silent Spring, A Spring without Bees is both a powerful cautionary tale and a call to action.

Book Description
This comprehensive compilation of official government documents provides complete details about Colony Collapse Disorder affecting honey bees, with the 2013 report on the suspected causes of the devastating problem, and earlier reports thoroughly tracing the history of CCD to it origin. During the winter of 2006-2007, some beekeepers began to report unusually high losses of 30-90 percent of their hives. As many as 50 percent of all affected colonies demonstrated symptoms inconsistent with any known causes of honeybee death: sudden loss of a colony's worker bee population with very few dead bees found near the colony. The queen and brood (young) remained, and the colonies had relatively abundant honey and pollen reserves. But hives cannot sustain themselves without worker bees and would eventually die. This combination of events resulting in the loss of a bee colony has been called Colony Collapse Disorder (CCD). Although agricultural records from more than a century ago note occasional bee "disappearances" and "dwindling" colonies in some years, it is uncertain whether the colonies had the same combination of factors associated with CCD. What we do know from the data from beekeepers for 2010/2011 is that CCD is still a concern. The new report notes the following: Consensus is building that a complex set of stressors and pathogens is associated with CCD, and researchers are increasingly using multi-factorial approaches to studying causes of colony losses. The parasitic mite Varroa destructor remains the single most detrimental pest of honey bees, and is closely associated with overwintering colony declines. Multiple virus species have been associated with CCD. Varroa is known to cause amplified levels of viruses. The bacterial disease European foulbrood is being detected more often in the U.S. and may be linked to colony loss. Nutrition has a major impact on individual bee and colony longevity. Research indicates that gut microbes associated with honey bees play key roles in enhancement of nutrition, detoxification of chemicals, and protection against diseases. Acute and sublethal effects of pesticides on honey bees have been increasingly documented, and are a primary concern. Further tier 2 (semi-field conditions) and tier 3 (field conditions) research is required to establish the risks associated with pesticide exposure to U.S. honey bee declines in general. The most pressing pesticide research questions lie in determining the actual field-relevant pesticide exposure bees receive and the effects of pervasive exposure to multiple pesticides on bee health and productivity of whole honey bee colonies. Long-term cryopreservation of honey bee semen has been successfully developed and provides the means for long-term preservation of "top-tier" domestic honey bee germplasm for breeding. Genetic variation improves bee thermoregulation, disease resistance and worker productivity. Genomic insights from sequencing the honey bee genome are now widely used to understand and address major questions of breeding, parasite interactions, novel controls (e.g., RNAi), and management to make bees less stressed and more productive.

Book Description
In 2005, beekeepers in the United States began observing a mysterious and disturbing phenomenon: once-healthy colonies of bees were suddenly collapsing, leaving behind empty hives full of honey and pollen. Over the following decade, widespread honeybee deaths—some of which have come to be called Colony Collapse Disorder (CCD)—have continued to bedevil beekeepers and threaten the agricultural industries that rely on bees for pollination. Scientists continue to debate the causes of CCD, yet there is no clear consensus on how to best solve the problem. Vanishing Bees takes us inside the debates over widespread honeybee deaths, introducing the various groups with a stake in solving the mystery of CCD, including beekeepers, entomologists, growers, agrichemical companies, and government regulators. Drawing from extensive interviews and first-hand observations, Sainath Suryanarayanan and Daniel Lee Kleinman examine how members of each group have acquired, disseminated, and evaluated knowledge about CCD. In addition, they explore the often-contentious interactions among different groups, detailing how they assert authority, gain trust, and build alliances. As it explores the contours of the CCD crisis, Vanishing Bees considers an equally urgent question: what happens when farmers, scientists, beekeepers, corporations, and federal agencies approach the problem from different vantage points and cannot see eye-to-eye? The answer may have profound consequences for every person who wants to keep fresh food on the table.
