Bee Catastrophe: 1/3 of Colonies Died This Winter, Worries Grow About Terminal Decline

Disturbing evidence that honeybees are in terminal decline has emerged from
the The decline of the country's estimated 2.4 million beehives began in 2006, when a phenomenon dubbed colony collapse disorder (CCD) led to the disappearance of hundreds of thousands of colonies. Since then more than three million colonies in the

The collapse in the global honeybee population is a major threat to crops. It is estimated that a third of everything we eat depends upon honeybee pollination, which means that bees contribute some £26bn to the global economy.
Potential causes range from parasites, such as the bloodsucking varroa mite, to viral and bacterial infections, pesticides and poor nutrition stemming from intensive farming methods. The disappearance of so many colonies has also been dubbed "Mary Celeste syndrome" due to the absence of dead bees in many of the empty hives.
A global review of honeybee deaths by the World Organisation for Animal Health (OIE) reported last week that there was no one single cause, but pointed the finger at the "irresponsible use" of pesticides that may damage bee health and make them more susceptible to diseases. Bernard Vallat, the OIE's director-general, warned: "Bees contribute to global food security, and their extinction would represent a terrible biological disaster."
Dave Hackenberg of Hackenberg Apiaries, the Pennsylvania-based commercial beekeeper who first raised the alarm about CCD, said that last year had been the worst yet for bee losses, with 62% of his 2,600 hives dying between May 2009 and April 2010. "It's getting worse," he said. "The AIA survey doesn't give you the full picture because it is only measuring losses through the winter. In the summer the bees are exposed to lots of pesticides. Farmers mix them together and no one has any idea what the effects might be."
Pettis agreed that losses in some commercial operations are running at 50% or greater. "Continued losses of this magnitude are not economically sustainable for commercial beekeepers," he said, adding that a solution may be years away. "Look at Aids, they have billions in research dollars and a causative agent and still no cure. Research takes time and beehives are complex organisms."
In the
John Chapple, chairman of the London Beekeepers' Association, put losses among his 150 members at between a fifth and a quarter. Eight of his 36 hives across the capital did not survive. "There are still a lot of mysterious disappearances," he said. "We are no nearer to knowing what is causing them."

In a hard-hitting report last year, the National Audit Office suggested that amateur beekeepers who failed to spot diseases in bees were a threat to honeybees' survival and called for the National Bee Unit to carry out more inspections and train more beekeepers. Last summer MPs on the influential cross-party public accounts committee called on the government to fund more research into what it called the "alarming" decline of honeybees.
The Department for the Environment, Food and Rural Affairs has contributed £2.5m towards a £10m fund for research on pollinators. The public accounts committee has called for a significant proportion of this funding to be "ring-fenced" for honeybees. Decisions on which research projects to back are expected this month.
WHY BEES MATTER
Flowering plants require insects for pollination. The most effective is the honeybee, which pollinates 90 commercial crops worldwide. As well as most fruits and vegetables – including apples, oranges, strawberries, onions and carrots – they pollinate nuts, sunflowers and oil-seed rape. Coffee, soya beans, clovers – like alfafa, which is used for cattle feed – and even cotton are all dependent on honeybee pollination to increase yields.In the
