WASHINGTON (AFP) - US beekeepers have been stung in recent months by the mysterious disappearance of millions of bees threatening honey supplies as well as crops which depend on the insects for pollination.
Bee numbers on parts of the east coast and in Texas have fallen by more than 70 percent, while California has seen colonies drop by 30 to 60 percent.
According to estimates from the US Department of Agriculture, bees are vanishing across a total of 22 states, and for the time being no one really knows why.
"Approximately 40 percent of my 2,000 colonies are currently dead and this is the greatest winter colony mortality I have ever experienced in my 30 years of beekeeping," apiarist Gene Brandi, from the California State Beekeepers Association, told Congress recently.
It is normal for hives to see populations fall by some 20 percent during the winter, but the sharp loss of bees is causing concern, especially as domestic US bee colonies have been steadily decreasing since 1980.
There are some 2.4 million professional hives in the country, according to the Agriculture Department, 25 percent fewer than at the start of the 1980s.
And the number of beekeepers has halved.
The situation is so bad, that beekeepers are now calling for some kind of government intervention, warning the flight of the bees could be catastrophic for crop growers.
Domestic bees are essential for pollinating some 90 varieties of vegetables and fruits, such as apples, avocados, and blueberries and cherries.
"The pollination work of honey bees increases the yield and quality of United States crops by approximately 15 billion dollars annually including six billion in California," Brandi said.
California's almond industry alone contributes two billion dollars to the local economy, and depends on 1.4 million bees which are brought from around the US every year to help pollinate the trees, he added.
The phenomenon now being witnessed across the United States has been dubbed "colony collapse disorder," or CCD, by scientists as they seek to explain what is causing the bees to literally disappear in droves.
The usual suspects to which bees are known to be vulnerable such as the varroa mite, an external parasite which attacks honey bees and which can wipe out a hive, appear not to be the main cause.
"CCD is associated with unique symptoms, not seen in normal collapses associated with varroa mites and honey bee viruses or in colony deaths due to winter kill," entomologist Diana Cox-Foster told the Congress committee.
In cases of colony collapse disorder, flourishing hives are suddenly depopulated leaving few, if any, surviving bees behind.
The queen bee, which is the only one in the hive allowed to reproduce, is found with just a handful of young worker bees and a reserve of food.
Curiously though no dead bees are found either inside or outside the hive.
The fact that other bees or parasites seem to shun the emptied hives raises suspicions that some kind of toxin or chemical is keeping the insects away, Cox-Foster said.
Those bees found in such devastated colonies also all seem to be infected with multiple micro-organisms, many of which are known to be behind stress-related illness in bees.
Scientists working to unravel the mysteries behind CCD believe a new pathogen may be the cause, or a new kind of chemical product which could be weakening the insects' immune systems.
The finger of suspicion is being pointed at agriculture pesticides such as the widely-used neonicotinoides, which are already known to be poisonous to bees.
France saw a huge fall in its bee population in the 1990s, blamed on the insecticide Gaucho which has now been banned in the country.
How were North American trees and plants pollinated before the Europeans introduced the honey bee?
Hives only produce as many workers as they can support. CCD is an interruption of this process. It is not a pesticide kill. CCD can be caused by attempts to mimic pollination using various pheromones. A principal component of this would be farnesol. Bees that have low levels of farnesol in their honey tend to be more inclined to mite infestation.
Well I had one land on my shoulder just the other day.
Somebody told them to buzz off, and, well...
I live in farming country and both sets of my grandparents were farmers.
I don’t think this is a laughing matter. You can’t laugh it up on the internet if you’re starving because the bees haven’t pollinated the crops.
Am I alarmist? Maybe.
Is this the end of the world? Probably not.
Worth looking into further, and more seriously? Most definitely.
Sincerely,
CD
AHA : the X FILES and KILLER BEES, must be the rebel aliens killing the bees...
I have a huge flower garden which attracts many bees. I will be observing carefully what happens in the next month or so. I would note that I have many honeybees because there is a beekeeper fairly nearby, but I also have many other kinds of bees. The reported bee losses are apparently honey bees, and, of course, beekeepers would notice that. As far as pollination goes, honeybees are not the only ones in that line of work, so part of the question has to be whether the decline is in the honey bee species or is a general problem affecting many other pollinators.
It is not a pesticide kill.
Sure.
A microscope will quickly prove or disprove mites. If it is mites, they’d be widely publicized by now. OTOH, if it is NOT mites, well, certain agencies and companies would prefer to NOT have it publicized in a big way that it is not mites.
They will put off throwing a handful of dead bees into a blender and then up the tube of a chromatograph for as long as they can, and hope to quietly remove the nicotinamides from production and use.
A quick web search leads me to believe that 'tomatoes' is the correct spelling.
41,200,000 for tomatoes / 630,000 for tomatos
It is utterly amazing the number of Libs I run into that scream about the Kyoto treaty. Not a single one has read it or knows anything about it that I've encountered. Equally amusing is the lack of knowledge that the Senate voted it down 99-0 and it was Clinton, not Bush, who refused to sign it.
Do they try to take advantage of social give away programs?
Thank you Perfect Stranger - I didn’t know there could be more than one way to spell it. I’ll go with tomatoes from now on. I could have looked in the dictionary but didn’t take the time. You wouldn’t happen to know the Vice President’s name that misspelled potato, would you?
Good morning. We didn’t get down to freezing last night but we did have SNOW! Unbelievable event. There was an inch or two that had collected in the valleys of the roof.
We can stick our toes in the Gulf of Mexico and had snow on April 8th.
LOL!!

Thank you very much. It was driving me crazy but I had a contest going with myself that I couldn’t look it up but would remember before anyone on Free Republic answered. - I lost. Either he was very forgetable or my memory is going.
The bees disappearing is really disturbing . Also were supposed to have the cicadas appear again too this summer ....
