Results of a new survey released Tuesday paint another dire picture of the population of bees in the United States.

Nearly a third of managed honey bee colonies were lost this past winter, the United States Department of Agriculture (USDA), the Bee Informed Partnership and the Apiary Inspectors of America (AIA) found, a 42% increase in loss over the previous winter.

But USDA bee expert Dr. Jeff Pettis, who worked on the study, also noted that "the 31 percent figure likely under-represents the losses, as we saw many weak colonies that were not actually dead."

Rather than showing evidence of colony collapse disorder (CCD), Pettis said most colonies "dwindled away rather than suffering from the sudden onset of CCD."

70% of the survey respondents reported a loss over 15% — a loss percentage deemed "acceptable."

The 6 year average total loss is also far above that "acceptable" level, averaging 30.5%.

The analysis was done by a team of 11 researchers led by Dennis vanEngelsdorp, an entomologist at the University of Maryland and director of the Bee Informed Partnership.

“We are one poor weather event or high winter bee loss away from a pollination disaster.”

Dr. Jeff PettisVanEngelsdorp pointed to the Midwest's drought as being one of the possible factors, as the bees may have been forced to look to flowering crops for nectar rather than wildflowers, and those crops may have had "unusually high" levels of pesticides.

Also a potential factor, stated vanEngelsdorp, is the fact that high corn prices lead to cornfields replacing some prairie and shrubs.

In a separate report released last week by the USDA and EPA on honey bee health, multiple factors were cited as responsible for the declining bee population, including pesticides.

The study highlighted the need for bees for the nation's food security. With bee populations declining year after year, Pettis said, “We are one poor weather event or high winter bee loss away from a pollination disaster.”

Following the study, Paul Towers, media director with the Pesticide Action Network, told IPS that the EPA/USDA study shows that action does need to happen, and fast:

“The report makes a compelling case that multiple factors are at play and that we do need to take action, but this needs to be done far more quickly,” Paul Towers, media director with the Pesticide Action Network, an advocacy group, told IPS.

“The five-to-ten-year timeframe these agencies are now saying they will follow is not fast enough. In fact, there is great imperative here: bees are a clear indicator of the overall health of our agricultural system, so if we’re unable to protect the pollinators we’ll put our entire agricultural system at risk.”

If this trend continues, we are clearly seeing our own extinction event, unraveling in slow motion. 5 years after most of the bees are dead, we will die. Humanity ceases to exist because it killed the bees.--jef

Is the Mystery Behind the Shocking Die-off of Bees Really Solved?

The New York Times essentially called it 'case closed' on Colony Collapse Disorder, but there is good reason to be wary about their reporting.

The New York Times made a long-awaited (and much emailed) announcement on its front page last week: The mystery of the ongoing and agriculturally devastating bee die-off (aka Colony Collapse Disorder, or CCD) has been cracked!

I'm not trying to hype the news. Here's the headline and lede:

Scientists and Soldiers Solve a Bee Mystery

It has been one of the great murder mysteries of the garden: what is killing off the honeybees?

Since 2006, 20 to 40 percent of the bee colonies in the United States alone have suffered "colony collapse." Suspected culprits ranged from pesticides to genetically modified food.

Now, a unique partnership -- of military scientists and entomologists -- appears to have achieved a major breakthrough: identifying a new suspect, or two.

A fungus tag-teaming with a virus have apparently interacted to cause the problem, according to a paper by Army scientists in Maryland and bee experts in Montana in the online science journal PLoS One.

It's easy to miss, but in that last sentence, reporter Kirk Johnson takes a wrong turn. In essence, he confuses proximate and efficient causes (i.e. what bees ultimately succumb to vs. what makes hives susceptible to collapse) and from that logical error, a whole series of cascading failures ensue. But don't take my word for it. Go read Katherine Eban's crack piece of reporting for Fortune that dissects the problematic nature of the Times article; the underlying study; its lead author, Jerry Bromenshenk; and the role in the whole debate of the pesticide company Bayer CropScience.

The enigma wrapped in a mystery coated with pesticide

Let's be clear: The study itself makes no conclusive claims about the causes of colony collapse disorder. Eban quotes from the paper that the research does not "clearly define" that the virus/fungus combination is "a marker, a cause, or a consequence of CCD." A scientist interviewed by Eban very helpfully offers the metaphor of HIV to describe what's going on with bees. HIV doesn't kill you -- it's the opportunistic infections and diseases that follow HIV's dismantling of a sufferer's immune system that do. In the case of bees, the virus/fungus combo are most likely the follow-on infections that kill off an already weakened hive.

The Times blunder goes beyond whether Johnson or his editor misinterpreted the results of new research. Unfortunately, as Eban details -- in part drawing on an unpublished piece she wrote for the now-defunct Portfolio magazine -- the Times left out key pieces of the real story of the fight over research into what's killing the bees.

As I wrote last January, many scientists believe that a novel class of pesticides called neonicotinoids -- which are insect neurotoxins -- has played a major role in CCD worldwide. An Italian entomologist at the University of Padua, Vincenzo Girolami, has research currently undergoing peer review showing that bees can be exposed to lethal levels of these pesticides through the use of seeding machines that sow neonicotinoid-coated seeds. These devices throw up a toxic cloud of pesticide as they work: bees fly through the cloud and either die or take the pesticide back to the hive. Once inside, even at low doses, it can cause disorientation or, as Girolami calls it, "intoxication" of whole hives.

The maker of this pesticide is Bayer CropScience. What does a corporation do when it discovers it may have developed and marketed a dangerous and potentially devastating product? Here in America, you confuse, you obfuscate, and you buy off scientists.

And as Eban skillfully details, that's exactly what Bayer has been doing for the last decade or so.

Beeing clear

Which brings us back to Bromenshenk. He was an expert witness for a group of beekeepers that in 2003 sued Bayer over the pesticide Imidacloprid. Bromenshenk later backed out of the lawsuit and, soon after, Bayer gave Bromenshenk a "research grant." But it gets worse. Eban reports something the Times piece doesn't: that Bromenshenk's consulting company, Bee Alert Technology, is developing diagnostic tools for "various bee ailments." The company stands to profit from curing bee diseases -- and thus it's rather convenient that Bromenshenk has published research that points the finger towards "treatable" conditions, rather than pesticides, as the primary culprit in bee deaths. Indeed, he had admitted as much to Eban while she was researching her Portfolio piece.

While this tremendous potential conflict doesn't necessarily invalidate Bromenshenk's findings, it certainly warrants a mention.

So where does this leave us? In an email exchange with me, the Italian scientist Girolami said he agrees with many of the experts Eban interviewed: The virus/fungus combination is secondary. In Girolami's opinion, the underlying causes of CCD -- the factors that are weakening the hives and making them susceptible to infection and die-offs -- are most likely neonicotinoids along with the Varroa mite, a parasite that can infect and destroy hives all on its own.

In fact, last year Italy banned neonicotinoid-coated corn seeds and, according to this report, after the first non-neonicotinoid sowing, nary a hive was lost, although neonicotinoid spraying is still allowed in some areas -- and still linked with bee deaths. France has also banned coated seeds -- though there, as in Germany, the pesticide lobby has fended off total bans for now. As for the U.S., Bayer successfully convinced a judge to throw out crucial evidence in the beekeeper lawsuit and has, to date, prevented the EPA from releasing the data the agency used to approve neonicotinoids in the first place.

Eban concludes with the observation that little neonicotinoid research is going on in the U.S .at the moment, thanks in large part to Bayer's efforts to "support" scientists who work in other, shall we say, less-sensitive areas. It seems it is up to scientists outside the U.S., in countries less beholden to corporate interests, to do the scientific heavy lifting.

Ah, America. Fighting hard for the freedom to spray toxic chemicals everywhere.

Bee Catastrophe

At certain points over the last couple of years, I have remarked to a few people that if there is a catastrophic end to humanity, it won't come from an asteroid, super volcano, global warming, or nuclear annihilation--it will come in the form of a tiny space that no longer contains a bee, or the hives which no longer contain bee colonies. When there is no pollination, everything green will die. The domino effect will reach us very quickly.

1/3 of Colonies Died This Winter, Worries Grow About Terminal Decline
By Alison Benjamin, The Observer UK
May 3, 2010

Disturbing evidence that honeybees are in terminal decline has emerged from the United States where, for the fourth year in a row, more than a third of colonies have failed to survive the winter.

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 US and billions of honeybees worldwide have died and scientists are no nearer to knowing what is causing the catastrophic fall in numbers.

The number of managed honeybee colonies in the US fell by 33.8% last winter, according to the annual survey by the Apiary Inspectors of America and the US government's Agricultural Research Service (ARS).

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.

US scientists have found 121 different pesticides in samples of bees, wax and pollen, lending credence to the notion that pesticides are a key problem. "We believe that some subtle interactions between nutrition, pesticide exposure and other stressors are converging to kill colonies," said Jeffery Pettis, of the ARS's bee research laboratory.

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 UK it is still too early to judge how Britain's estimated 250,000 honeybee colonies have fared during the long winter. Tim Lovett, president of the British Beekeepers' Association, said: "Anecdotally, it is hugely variable. There are reports of some beekeepers losing almost a third of their hives and others losing none." Results from a survey of the association's 15,000 members are expected this month.

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."

Bee farmers in Scotland have reported losses on the American scale for the past three years. Andrew Scarlett, a Perthshire-based bee farmer and honey packer, lost 80% of his 1,200 hives this winter. But he attributed the massive decline to a virulent bacterial infection that quickly spread because of a lack of bee inspectors, coupled with sustained poor weather that prevented honeybees from building up sufficient pollen and nectar stores.

The government's National Bee Unit has always denied the existence of CCD in Britain, despite honeybee losses of 20% during the winter of 2008-09 and close to a third the previous year. It attributes the demise to the varroa mite – which is found in almost every UK hive – and rainy summers that stop bees foraging for food.

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 UK alone, honeybee pollination is valued at £200m. Mankind has been managing and transporting bees for centuries to pollinate food and produce honey, nature's natural sweetener and antiseptic. Their extinction would mean not only a colorless, meatless diet of cereals and rice, and cottonless clothes, but a landscape without orchards, allotments and meadows of wildflowers – and the collapse of the food chain that sustains wild birds and animals.
