A mysterious decimation of bee populations has German beekeepers worried, while a similar phenomenon in the United States is gradually assuming catastrophic proportions. The consequences for agriculture and the economy could be enormous.

    Walter Haefeker is a man who is used to painting grim scenarios. He sits on the board of directors of the German Beekeepers Association (DBIB) and is vice president of the European Professional Beekeepers Association. And because griping is part of a lobbyist's trade, it is practically his professional duty to warn that "the very existence of beekeeping is at stake."

    The problem, says Haefeker, has a number of causes, one being the varroa mite, introduced from Asia, and another is the widespread practice in agriculture of spraying wildflowers with herbicides and practicing monoculture. Another possible cause, according to Haefeker, is the controversial and growing use of genetic engineering in agriculture.

    As far back as 2005, Haefeker ended an article he contributed to the journal Der Kritischer Agrarbericht (Critical Agricultural Report) with an Albert Einstein quote: "If the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees, no more pollination, no more plants, no more animals, no more man."

    Mysterious events in recent months have suddenly made Einstein's apocalyptic vision seem all the more topical. For unknown reasons, bee populations throughout Germany are disappearing - something that is so far only harming beekeepers. But the situation is different in the United States, where bees are dying in such dramatic numbers that the economic consequences could soon be dire. No one knows what is causing the bees to perish, but some experts believe that the large-scale use of genetically modified plants in the US could be a factor.

    Felix Kriechbaum, an official with a regional beekeepers' association in Bavaria, recently reported a decline of almost 12 percent in local bee populations. When "bee populations disappear without a trace," says Kriechbaum, it is difficult to investigate the causes, because "most bees don't die in the beehive." There are many diseases that can cause bees to lose their sense of orientation so they can no longer find their way back to their hives.

    Manfred Hederer, the president of the German Beekeepers Association, almost simultaneously reported a 25 percent drop in bee populations throughout Germany. In isolated cases, says Hederer, declines of up to 80 percent have been reported. He speculates that "a particular toxin, some agent with which we are not familiar," is killing the bees.

    Politicians, until now, have shown little concern for such warnings or the woes of beekeepers. Although apiarists have been given a chance to make their case - for example in the run-up to the German cabinet's approval of a genetic engineering policy document by Minister of Agriculture Horst Seehofer in February - their complaints are still largely ignored.

    Even when beekeepers actually go to court, as they recently did in a joint effort with the German chapter of the organic farming organization Demeter International and other groups to oppose the use of genetically modified corn plants, they can only dream of the sort of media attention environmental organizations like Greenpeace attract with their protests at test sites.

   But that could soon change. Since last November, the US has seen a decline in bee populations so dramatic that it eclipses all previous incidences of mass mortality. Beekeepers on the east coast of the United States complain that they have lost more than 70 percent of their stock since late last year, while the west coast has seen a decline of up to 60 percent.

    In an article in its business section in late February, the New York Times calculated the damage US agriculture would suffer if bees died out. Experts at Cornell University in upstate New York have estimated the value bees generate - by pollinating fruit and vegetable plants, almond trees and animal feed like clover - at more than $14 billion.

    Scientists call the mysterious phenomenon "Colony Collapse Disorder" (CCD), and it is fast turning into a national catastrophe of sorts. A number of universities and government agencies have formed a "CCD Working Group" to search for the causes of the calamity, but have so far come up empty-handed. But, like Dennis vanEngelsdorp, an apiarist with the Pennsylvania Department of Agriculture, they are already referring to the problem as a potential "AIDS for the bee industry."

    One thing is certain: Millions of bees have simply vanished. In most cases, all that's left in the hives are the doomed offspring. But dead bees are nowhere to be found - neither in nor anywhere close to the hives. Diana Cox-Foster, a member of the CCD Working Group, told The Independent that researchers were "extremely alarmed," adding that the crisis "has the potential to devastate the US beekeeping industry."

    It is particularly worrisome, she said, that the bees' death is accompanied by a set of symptoms "which does not seem to match anything in the literature."

    In many cases, scientists have found evidence of almost all known bee viruses in the few surviving bees found in the hives after most have disappeared. Some had five or six infections at the same time and were infested with fungi - a sign, experts say, that the insects' immune system may have collapsed.

    The scientists are also surprised that bees and other insects usually leave the abandoned hives untouched. Nearby bee populations or parasites would normally raid the honey and pollen stores of colonies that have died for other reasons, such as excessive winter cold. "This suggests that there is something toxic in the colony itself which is repelling them," says Cox-Foster.

    Walter Haefeker, the German beekeeping official, speculates that "besides a number of other factors," the fact that genetically modified, insect-resistant plants are now used in 40 percent of cornfields in the United States could be playing a role. The figure is much lower in Germany - only 0.06 percent - and most of that occurs in the eastern states of Mecklenburg-Western Pomerania and Brandenburg. Haefeker recently sent a researcher at the CCD Working Group some data from a bee study that he has long felt shows a possible connection between genetic engineering and diseases in bees.

    The study in question is a small research project conducted at the University of Jena from 2001 to 2004. The researchers examined the effects of pollen from a genetically modified maize variant called "Bt corn" on bees. A gene from a soil bacterium had been inserted into the corn that enabled the plant to produce an agent that is toxic to insect pests. The study concluded that there was no evidence of a "toxic effect of Bt corn on healthy honeybee populations." But when, by sheer chance, the bees used in the experiments were infested with a parasite, something eerie happened. According to the Jena study, a "significantly stronger decline in the number of bees" occurred among the insects that had been fed a highly concentrated Bt poison feed.

    According to Hans-Hinrich Kaatz, a professor at the University of Halle in eastern Germany and the director of the study, the bacterial toxin in the genetically modified corn may have "altered the surface of the bee's intestines, sufficiently weakening the bees to allow the parasites to gain entry - or perhaps it was the other way around. We don't know."

    Of course, the concentration of the toxin was ten times higher in the experiments than in normal Bt corn pollen. In addition, the bee feed was administered over a relatively lengthy six-week period.

    Kaatz would have preferred to continue studying the phenomenon but lacked the necessary funding. "Those who have the money are not interested in this sort of research," says the professor, "and those who are interested don't have the money."      Go to Original

Colorado beekeepers stung by mysteriously vanishing colonies.

    Like other Colorado beekeepers, Jeff Theobald knows that between 2 percent and 10 percent of his bees typically won't survive winter, but this year, the loss rate is 40 percent and rising as entire colonies vanish without a trace.

    "It's just bizarre," said Theobald, who runs Grand Mesa Honey Farm in Delta. "I've had hives that had dead bees in them - 4,000 to 5,000 dead bees - and hives that were completely empty. The bees were just gone."

    Regional disasters have afflicted beekeepers in the past, but baffled entomologists and agricultural experts call this the first national crisis, with potentially grave consequences. Approximately $14.6 billion worth of U.S. nut, fruit and vegetable crops depend on bee pollination.

    Throughout the U.S., honeybee colonies, including approximately 30,000 colonies in Colorado, are affected by what researchers are calling colony collapse disorder. To date, the disorder has been identified in 24 states.

    "The map changes almost daily," said Jerry Bromenshenk, president of Bee Alert Technology, a research company affiliated with the University of Montana. "Almost every time the phone rings, we say, 'Is that another state calling in with a problem?"'

    The accounts are eerily identical: A bee colony that appeared perfectly strong and healthy during a late 2006 inspection abruptly disappears when beekeepers make their first bee-yard rounds in 2007. One commercial beekeeper with hives in Oklahoma and Texas lost 80 percent of his 13,000 colonies.

    "One day, you look at the bees and they're good," Bromenshenk said. "The next time you look in the box, you take a second look, pull the cover off, and you might have a queen and three young bees trying to keep things going. If it was a pesticide or a virus, you'd expect to find piles of dead bees in the box, and in the bee yard. But this looks like someone swept the bottom board clean."

    Where are the missing bees? Nobody knows. What's causing them to leave the hive? Nobody knows that, either. How many bees are missing?

    "We wish we knew, and we wish we had a means of collecting statistics," Bromenshenk said. "The problem is (that) the beekeepers we hear from are the ones who have a problem. And another problem is that we're not hearing from the beekeepers who aren't owning up, because they don't want growers to know."

    Still, there are few secrets in the relatively small, close-knit beekeeping community, one of the last agricultural domains still dominated by family dynasties.

    "Dad knows so many beekeepers, and a bunch of his friends have already had big losses," said Jeff Johnston, whose Colorado Honey Company processes honey from Colorado colonies kept by relatives and friends with operations from the Eastern Plains to the Western Slope. His father, Lyle, is currently in California, where almond growers pay $125 to $165 per hive.

    Lyle Johnston's business is based in Rocky Ford. He normally stays close to home to serve the farmers and ranchers who hire his bees, but the California almond crop is too lucrative to ignore.

    The Johnstons are among a handful of this state's commercial beekeepers whose colonies pollinate Eastern Plains alfalfa crops, Western Slope peaches, Rocky Ford cantaloupe and other crops that depend on honeybees. Hundreds of other hobbyist beekeepers maintain an average of a few dozen hives each throughout Colorado.

    As bees die, the price of replacement bees - which has already quadrupled in the past decade because so many bees succumb to mite infestations - is escalating.

    "If we don't have bees, then all (that) those folks in California have got is fancy shade trees," Theobald said. "I'm afraid attention won't be paid, and we'll be going to South America for fruits and vegetables."

    Theobald and his brother, Tom, a Niwot beekeeper for more than three decades, believe that colony collapse disorder is the result of long-ignored environmental regulations. When growers violate pesticide restrictions, the chemical residue poisons bees.

    Until the disorder was identified, pesticides and parasitic mites were the chief causes of colony die-offs. When Colorado's apiary program lost its funding in the early 1980s, government bee inspections ceased, leaving no one but the beekeepers to monitor the mite infestation or pesticide abuse.

    "Until then, I did routine disease inspections, and since the program went under, there've been all kinds of problems," said state entomologist Jerry Cochran.

    Tom Theobald agrees. He refers to the existing system as "the (Hurricane) Katrina model of management."

    "We've known this problem was coming for a long time," he said, "and the people in charge have not discussed the problems openly."

    "It's not colony collapse disorder. It's industry collapse disorder, and it's very serious."
