Available in PDF, EPUB and Kindle. Book excerpt: This is a print on demand edition of a hard to find publication. Starting in late 2006, commercial migratory beekeepers along the East Coast of the U.S. began reporting sharp declines in their honey bee colonies. Scientists named this phenomenon Colony Collapse Disorder (CCD). Overall, the number of managed honey bee colonies dropped an estimated 35.8% in the winter of 2007/2008. The reasons for colony losses are not yet known. Contents of this report: (1) Importance of Honey Bee Pollination; (2) Extent and Symptoms of CCD: Past Honey Bee Population Losses; How CCD Differs from Past Bee Colony Losses; Symptoms of CCD; Possible Causes of CCD; Other Related Events; (3) Issues for Congress; 2008 Farm Bill: Conservation; Research; Insurance and Disaster Provisions. Charts and tables.

Book excerpt: Colony Collapse Disorder (CCD) was a condition first noticed in 2006 when higher than normal losses of managed honey bee colonies were reported from all over the United States and other locations across the world. Due to the unusual symptoms and lack of known cause, scientists and beekeepers began studying CCD to determine potential causes. Consensus is that CCD is the result of multiple factors working together to weaken honey bee colonies. Although CCD has not been the cause of honey bee losses in the last few years, honey bees are still dying at rates that cannot meet the demand for honey bee pollination. The goal of the Care for the Colonies Campaign was to raise awareness about CCD and the factors affecting honey bees and to empower the audience to make decisions that promote honey bee health. The audience was reached through presentations, print materials, a campaign website, social media, and a podcast episode. The thesis includes a project description, background research on CCD and the impacts, an experiential journal detailing campaign activities, and appendices of all campaign materials.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last several decades declines in pollinator populations, especially those of wild bees and other insects, have raised awareness of the economic impact pollination services have for crop production. This awareness and concern was heightened by an ongoing loss of millions of managed honey bee colonies since the early 1950s. Colonies are used predominantly for pollination services in fruit and vegetable crops. During 2007, an unusually large overwintering loss in colonies that was not characterized by the presence of dead bees was termed colony collapse disorder (CCD), a syndrome in which hives lacked sufficient worker caste bees to maintain the queen and brood. Potential factors hypothesized to be associated with CCD include parasite infestations (e.g., Varroa mite) and pathogen infections (Nosema spp. fungus and viruses), insecticide exposure (especially to the neonicotinoid class), and poor nutrition owing to a reduction in landscape areas containing high quality floral resources. Although no one stressor has been definitively associated with CCD, possible interactions among them have only recently been studied. Of particular interest are possible interactions of Nosema spp. with neonicotinoid insecticide exposure. The main objective of this dissertation was an examination of these potential interactions using a combination of literature analysis, empirical study of Nosema infection prevalence in adult bees, and simulation modeling of the combined effects of several stressors on worker population abundance. After the introduction, the dissertation is divided into four chapters addressing the following objectives: (1) Comparison of regulatory procedures for risk assessment of insecticides potentially impacting honey bees in the United States and in the European Union; (2) Analysis of published literature that document potential interactions between bee pathogens, parasites, and neonicotinoid insecticide residues; (3) Analysis of field-collected apiary bees for prevalence of Nosema spores in association with land uses and the presence of neonicotinoid residues; (4) Use of the honey bee colony model BEEHAVE to predict colony collapse in the presence of pathogens and insecticide-induced mortality. Results of the various analyses suggest a need for modifying risk assessment procedures to include the interaction of pesticide residues with parasite/pathogen stressors.

Book excerpt: This report examines the recent sharp decline in U.S. honey bee colonies, which scientists are now calling the Colony Collapse Disorder (CCD). This phenomenon first became apparent among commercial migratory beekeepers along the East Coast during the last few months of 2006, and has since been reported nationwide. Honey bees are the most economically valuable pollinators of agricultural crops worldwide. 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 specialty crops. The monetary value of honey bees as commercial pollinators in the United States is estimated at about $15 billion annually.
