“They know what’s killing the bees, they’ve have known for years. Go to the EPA’s site and read some of the studies. This one in particular paints a pretty clear picture.” 

“Ugh…. I thought they figured out it was the low level neurotoxins in pesticides that played out over generations of hives?”

It is definitely this. There is just MASSIVE opposition to stopping use of them. My family has been involved in beekeeping in MN for 3 generations. Beekeepers are roughly split into three categories, large, small and hobbyist operations. The larger operations (things like Mel-O honey etc.) use big rig trucks to move large hive sections all over depending on what field a farmer needs pollinated. The smaller operations focus on apiaries and other smaller farms that they don’t have to move the hives as often or at all. Hobbyists obviously never move their hives during the season, but often don’t care if they die off in the winter.

The bees that are dying are from the LARGE operations, because they have the most contact with the pesticides in question. Which are the bad ones you ask? Neonicotinoids.


Colony Collapse Disorder: Common Pesticides Disrupt Brain Functioning in Bees.

Update via Reddit r/permaculture:

Recent bee related death reports:

Meanwhile, other reports of bees dying around Wilsonville and surrounding towns have prompted Xerces to check whether similar pesticides were used elsewhere.

“My worry is that we’re going to lose sight of the real message,” said Mace Vaughan of Xerces. “I think we’re (using insecticides) all over the place, and people are doing it in their backyards without even knowing it.”

U.S. Bee Deaths From Colony Collapse Disorder May Be Tied To Diet, Study Finds (Boston, MA)

Agrichemical and pesticide makers like Monsanto, Bayer AG and Syngenta are also launching projects to study and counter colony collapse.

Few deny that pesticides – particularly a class of commonly used insecticides called neonicotinoids – can be harmful to bees in the laboratory. It is unclear what threat the insecticides pose under current agricultural usage. Some scientists say habitat decline and disease-carrying parasites, such as the Varroa mite, are the chief cause of bee deaths.

One of every three bites of food we consume depends on pollination by honeybees, but these overlooked contributors to our food system are continuing to die in stubbornly perplexing ways.

In 2006, beekeepers started noticing that bees were abandoning their hives, a phenomenon scientists dubbed Colony Collapse Disorder. Since then, the American bee population has dropped by an average of 30 percent every year, sending researchers, beekeepers and farmers into a head-scratching frenzy to figure out the cause.

Study links insecticides to bee deaths (Quebec, Canada)

According to Jean-Pierre Chapleau, spokesman for the Quebec Beekeepers’ Federation, beekeepers want neonicotinoid insecticides banned.

“Neonicotinoid insecticides are overused,” he says. Chapleau said that beekeepers don’t blame farmers, because they can’t buy seeds that have not been treated with insecticides even if they want to.

The industry says that’s not accurate.

SBA president Phil McAnespie said: “Last summer and autumn were very bad, which is obviously an issue and viruses are associated with that. “I think most of the losses are down to the weather. Obviously, there is concern about neonicotinoids and there is ongoing research into that but I don’t think they have played any major part in this [the increase in bee deaths].”

Update: 1/3 of US Honeybee Colonies Died Last Winter, Threatening US Food Supply – “We’re getting closer & closer to the point where we don’t have enough bees in this country to meet pollination demands,” said entomologist Dennis vanEngelstorp, who led survey documenting declines. (wired.com)

Update: It’s confirmed: It’s getting worse. Cover of the NY Times today, edging out even the Taliban. Thing is, this threat we know how to stop.

“Bee Die-Off Soars, Putting Crops at Risk A mysterious malady seems to have expanded drastically in the past year, wiping out as many as half of the beehives needed to pollinate much of America’s produce.”

Exposure to commonly used pesticides directly disrupts brain functioning in bees, according to new research in Nature.”

While the study is the first to record that popular pesticides directly injure bee brain physiology, it adds to a slew of recent studies showing that pesticides, especially neonicotinoids, are capable of devastating bee hives and may be, at least, partly responsible for on-going Colony Collapse Disorder (CCD).

Christopher Connolly with the University of Dundee in Scotland and his team exposed honeybees to two pesticides at levels encountered in the wild: neonicotinoids and miticidal pesticides.

By recording brain activity after exposure, the researchers found that both pesticides directly hampered bee brain functioning, including blocking neurons from firing. The findings are especially notable for studying bees after exposure to the miticidal pesticide, which is used directly on bee hives to safeguard them from a common parasite, the Varroa destructor mite. In this case, however, the cure may be worse than the disease. Connolly explains:

“Much discussion of the risks posed by the neonicotinoid insecticides has raised important questions of their suitability for use in our environment. However, little consideration has been given to the miticidal pesticides introduced directly into honeybee hives to protect the bees from the Varroa mite. We find that both have negative impact on honeybee brain function.”

Furthermore the researchers found that when bees were exposed to both chemicals—the neonicotinoids and miticidal pesticides—their brain functioning and learning abilities were hurt even more.

The study is the first to show the direct brain impacts that may explain why bees exposed to these pesticides slow aberrant behavior, including losing their way easily and slow reactions.

Scientists both in the U.S. and Europe have recorded the complete collapse of hives following exposure. However, pesticide companies have continually argued that their products cause no harm to bees even as high-profile independent research from multiple sources appears to be telling a very different story.

The research has spurred some policy movement. France has banned the use of neonicotinoids on certain crops. The EU proposed a ban on neonicotinoids for two years after a committee looked at the research for six months. However, the ban was scuttled by opposition from Germany and the UK, though it could still come up in appeal.

Most recently, nine beekeeping and environmental groups sued the U.S. Environment Protection Agency (EPA) for failing to take action to protect bees.

Bees are key plant pollinators, and their decline has worried scientists, farmers, and policymakers worldwide. In the U.S. alone, bee pollination is estimated to be worth $8-12 billion. While bee declines have occurred in the past, researchers believe this one is much more severe.

Great article! That is the type of info that are supposed

to be shared around the web. Shame on Google for now not positioning this put up upper!

Come on over and talk over with my site . Thanks =)

BREAKING: 99.9% of all dinosaurs on Earth did not survive the asteroid impact 65 million years ago.

Seriously, enough fear mongering…

"Scientists have estimated that over the course of Earth's history, anywhere between 1 and 4 billion species have existed on this planet. Be it through disease, genetic obsolescence, over-predation or any number of other factors, the overwhelming majority of these species are now extinct. Of these billions of species, roughly 50 million still survive into the modern era. While these numbers are certainly extreme at first glance, it serves as proof that extinction, while a sad occurrence, is a part of life for all living things." http://curiosity.discovery.com/question/how-speci

Humans fear change – we like everything to stay the same, all the time. The same way we don't like our favorite restaurants going out of business, we don't like thinking that a species will go extinct (because it makes us realize that WE could go extinct). We fear that "everything will collapse" in a sort of butterfly-effect if one tiny cog on the gear breaks. This is absolutely not the case, as we know because of our scientific understanding of biology and ecosystems.

People also forget about this little thing called "evolution", which, as we know, is driven by "survival of the fittest". The species that best adapt to changes in their environment are the ones that survive. If the bees don't make it, they don't make it – just like the billions of other species that didn't make it (even before humans were around…). Changes in environment can cause species to go extinct, but look around – there is life EVERYWHERE. These changes can range from natural disasters, to asteroid impacts, to shifts in climate due to continental drift, to overpopulation of predators, to the under-supply of food source, to disease.

Reality: the population count of all species is always changing, and sometimes they go extinct. That's life, folks.

Maybe all the bees dying off isn't as scary as you think…stop freaking out, and please, stop fear mongering. Life will continue on this planet as it has for appx. 2 billion years.

I know what your counter fear-driven argument is going to be: "BUT IF ALL THE BEES DIE THEN OUR FOOD SUPPLY WILL DWINDLE BECAUSE THE BEES POLLINATE MOST OF OUR CROPS! THEN WE'LL BE THE ONES AT RISK OF POPULATION DECLINE!" Except that…that's not going to happen, for multiple reasons.

There are lots of numbers out that that get thrown around. I've seen claims as high as "1/3 of the foods we eat"…but here's the thing: just because we currently eat certain foods, doesn't mean we need to eat them to survive. You know what grows without the intervention of bees? Most plants…including the foods that sustain most of the world: from corn and rice, to potatoes to various leafy greens. Second, evolution is similar to capitalism: if there is supply available, a demand will arise. So honey bees stop pollinating? Well, either a stronger species of honey bee will come about or different species will take their place in the usage of the pollen (causing pollination). Bees aren't the only species that use pollen, you know. If there is more pollen to go around for other species (because the bees aren't using it), those other species will likely grow in population and continue the pollination work of the bees.

Life on this plant is far more complex than you can imagine. Stop worrying about every single little cog…the planet, and the life on it, will continue as it has for 2 billion years.
