SCIENCE DAILY 19/02/17 Bee decline threatens US crop production - First US wild bee map reveals 139 'trouble zone' counties. The first-ever study to map U.S. wild bees suggests they are disappearing in the country's most important farmlands -- from California's Central Valley to the Midwest's corn belt and the Mississippi River valley.
If wild bee declines continue, it could hurt U.S. crop production and farmers' costs, said Taylor Ricketts, a conservation ecologist at the University of Vermont, at the American Association for the Advancement of Science (AAAS) annual meeting panel, Plan Bee: Pollinators, Food Production and U.S. Policy on Feb. 19. "This study provides the first national picture of wild bees and their impacts on pollination," said Ricketts, Director of UVM's Gund Institute for Ecological Economics, noting that each year $3 billion of the U.S. economy depends on pollination from native pollinators like wild bees.
At the event, Ricketts also introduced a new mobile app that he is co-developing to help farmers upgrade their farms to better support wild bees.

MONTANA STATE UNIVERSITY 04/05/15 MSU virologist receives grants for research on honeybee health. May 4, 2015 -- Jenny Lavey, MSU News Service A Montana State University virologist recently was awarded three grants to study why honeybees, the primary pollinator force of the nation’s food supply, are experiencing high losses.
Michelle Flenniken, assistant professor in the Department of Plant Sciences and Plant Pathology in MSU’s College of Agriculture, recently received three grants to investigate the role of viruses and other pathogens on honeybee health. Flenniken received an Agriculture Food and Research Initiative grant from the U.S. Flenniken’s research comes at a time when the national beekeeping industry is facing high annual losses of honeybee colonies, about 32 percent a year, according to the National Department of Agricultural Statistics (NASS) and the Bee Informed Partnership.
Growers rent about 1.6 million honeybee colonies each year to pollinate more than 50 major cash crops, mostly fruit and vegetables, according to the USDA. PLOS 04/06/15 Bumblebee Pupae Contain High Levels of Aluminium. Abstract The causes of declines in bees and other pollinators remains an on-going debate.
While recent attention has focussed upon pesticides, other environmental pollutants have largely been ignored. Aluminium is the most significant environmental contaminant of recent times and we speculated that it could be a factor in pollinator decline. Herein we have measured the content of aluminium in bumblebee pupae taken from naturally foraging colonies in the UK. PLOS 23/02/12 Predictive Markers of Honey Bee Colony Collapse. Abstract Across the Northern hemisphere, managed honey bee colonies, Apis mellifera, are currently affected by abrupt depopulation during winter and many factors are suspected to be involved, either alone or in combination.
Parasites and pathogens are considered as principal actors, in particular the ectoparasitic mite Varroa destructor, associated viruses and the microsporidian Nosema ceranae.

By Kim Kaplan May 13, 2015 WASHINGTON, May 13, 2015 — Losses of managed honey bee colonies were 23.1 percent for the 2014-2015 winter but summer losses exceeded winter numbers for the first time, making annual losses for the year 42.1 percent, according to preliminary results of the annual survey conducted by the Bee Informed Partnership ( the U.S.
Department of Agriculture (USDA) and the Apiary Inspectors of America. The winter loss improvement was about 0.6 percentage points less than the losses reported for the 2013-2014 winter. This is the second year in a row that winter losses have been noticeably lower than the nine year average winter loss of 28.7 percent. However, beekeepers are not losing colonies only in the winter but also throughout the summer, sometimes at significant levels. Total annual losses were 42.1 percent for April 2014 through April 2015. A complete analysis of the survey data will be published later this year.

SCIENCE 27/03/15 Bee declines driven by combined stress from parasites, pesticides, and lack of flowers.
Abstract Bees are subject to numerous pressures in the modern world.
The abundance and diversity of flowers has declined; bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by humans. Climate change is likely to exacerbate these problems in the future. Stressors do not act in isolation; for example, pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to parasites.

PARLEMENT EUROPEEN - Réponse à question N°E-008771-13 Mass extinction of bees. USDA 25/03/13 Honey Bees and Colony Collapse Disorder - 2012 CCD Progress Report. Honey bees, which are a critical link in U.S. agriculture, have been under serious pressure from a mystery problem: Colony Collapse Disorder (CCD), which is syndrome defined as a dead colony with no adult bees or dead bee bodies but with a live queen and usually honey and immature bees still present.
No scientific cause for CCD has been proven. But CCD is far from the only risk to the health of honey bees and the economic stability of commercial beekeeping and pollination operations in the United States. COLOSS - Dernières présentations de conférences. UNIVERSITY OF CALIFORNIA SAN FRANCISCO 07/06/11 UCSF Finds New Bee Viruses, Offers Baseline to Study Colony Collapse. Working in the lab, from left, are Michelle Flenniken, a postdoctoral scholar, Joseph DeRisi, PhD, a Howard Hughes Medical Institute investigator and professor of biochemistry and biophysics at UCSF, and Charles Runckel, a graduate student.
A 10-month study of healthy honey bees by University of California, San Francisco (UCSF) scientists has identified four new viruses that infect bees, while revealing that each of the viruses or bacteria previously linked to colony collapse is present in healthy hives as well. The study, which followed 20 colonies in a commercial beekeeping operation of more than 70,000 hives as they were transported across the country pollinating crops, was conducted to answer one basic question: what viruses and bacteria exist in a normal colony throughout the year?
The results depict a distinct pattern of infections through the seasons and provide a normal baseline for researchers studying a colony – the bee population within a hive – that has collapsed.

PLOS 30/06/11 Lack of Evidence for an Association between Iridovirus and Colony Collapse Disorder. Colony collapse disorder (CCD) is characterized by the unexplained losses of large numbers of adult worker bees (Apis mellifera) from apparently healthy colonies.
Although infections, toxins, and other stressors have been associated with the onset of CCD, the pathogenesis of this disorder remains obscure. Recently, a proteomics study implicated a double-stranded DNA virus, invertebrate iridescent virus (Family Iridoviridae) along with a microsporidium (Nosema sp.) as the cause of CCD.

NATIONAL GEOGRAPHIC 10/05/13 The Plight of the Honeybee - Billions of dollars—and a way of life—ride on saving pollinators. Part of our weekly "In Focus" series—stepping back, looking closer. Bees are back in the news this spring, if not back in fields pollinating this summer's crops. The European Union (EU) has announced that it will ban, for two years, the use of neonicotinoids, the much-maligned pesticide group often fingered in honeybee declines. The U.S. hasn't followed suit, though this year a group of beekeepers and environmental and consumer groups sued the EPA for not doing enough to protect bees from the pesticide onslaught.
For the last several years scientists have fretted over the future of bees, and although research has shed much light on the crisis, those in the bee business—from hive keepers to commercial farmers—say the insects remain in deep trouble as their colonies continue to struggle. The current crisis arose during the fall of 2006 as beekeepers around the country reported massive losses—more than a third of hives on average and up to 90 percent in some cases.
The Threat From Pesticides. ARS USDA - JUIN 2012 - Colony Collapse Disorder Progress Report. IOWA STATE UNIVERSITY 11/06/12 Iowa State Researchers Explore Possible Causes of Honeybee Disappearance. AMES, Iowa — Iowa State University is taking a team approach in studying what is behind the disappearance of honeybees known as "Colony Collapse Disorder. " Amy Toth, assistant professor in Iowa State's ecology, evolution and organismal biology department, was awarded an Agriculture and Food Research Initiative grant by the U.S. Department of Agriculture to explore the importance of nutritional stress and viruses on honeybee health. She is working with researchers Allen Miller and Jimena Carillo-Tripp in the plant pathology and microbiology department and Bryony Bonning in the entomology department. "We're taking a novel approach to studying the colony collapse phenomenon," Toth said.
