Bee Die-Off Theories: Looks Like We Have A Deadly Winner..

Wik-Bee Leaks: EPA Document Shows It Knowingly Allowed Pesticide That Kills Honey Bees  With "This is how the government and corporations are killing you" excerpts in italics:

The world honey bee population has plunged in recent years, worrying beekeepers and farmers who know how critical bee pollination is for many crops. A number of theories have popped up as to why the North American honey bee population has declined--electromagnetic radiation, malnutrition, and climate change have all been pinpointed. Now a leaked EPA document reveals that the agency allowed the widespread use of a bee-toxic pesticide, despite warnings from EPA scientists. 

The document, which was leaked to a Colorado beekeeper, shows that the EPA has ignored warnings about the use of clothianidin, a pesticide produced by Bayer that mainly is used to pre-treat corn seeds. The pesticide scooped up $262 million in sales in 2009 by farmers, who also use the substance on canola, soy, sugar beets, sunflowers, and wheat, according to Grist.

The leaked document (PDF) was put out in response to Bayer's request to approve use of the pesticide on cotton and mustard. The document invalidates a prior Bayer study that justified the registration of clothianidin on the basis of its safety to honeybees:

Clothianidin’s major risk concern is to nontarget insects (that is, honey bees). Clothianidin is a neonicotinoid insecticide that is both persistent and systemic. Acute toxicity studies to honey bees show that clothianidin is highly toxic on both a contact and an oral basis. Although EFED does not conduct RQ based risk assessments on non-target insects, information from standard tests and field studies, as well as incident reports involving other neonicotinoids insecticides (e.g., imidacloprid) suggest the potential for long-term toxic risk to honey bees and other beneficial insects.
And:
Clothianidin has already been banned by Germany, France, Italy, and Slovenia for its toxic effects. So why won't the EPA follow? The answer probably has something to do with the American affinity for corn products. But without honey bees, our entire food supply is in trouble.

From:  Timeline of a Bee Massacre: EPA Still Allowing Hive-Killing Pesticide

Beekeepers across the U.S. are reporting record low honey crops as their bees fail to make it through the winter. One-third of American agriculture, which relies on bee pollination, is at stake. And the problem may be at least partially attributable to clothianidin, a Bayer-branded pesticide used on corn and other crops.

But as we revealed last week, the EPA knew that clothianidin could be toxic when the product came on the market in 2003. So why is it still on the market?

The bee-toxic pesticide problem can be traced back to 1994, when the first neonicotinoid pesticide (Imidacloprid) was released. Neonicotinoids like imidacloprid and clothianidin disrupt the central nervous system of pest insects, and are supposed to be relatively non-toxic to other animals. But there's a problem: The neonicotinoids coat plant seeds, releasing insecticides permanently into the plant. The toxins are then released in pollen and nectar--where they may cause bees to become disoriented and die.
And:
The EPA first brought up the link between clothianidin and bees before the pesticide's release in February 2003. The agency originally planned to withhold registration of the pesticide because of concerns about toxicity in bees, going so far as to suggest that the product come with a warning label (PDF): "This compound is toxic to honey bees. The persistence of residues and the expression clothianidin in nectar and pollen suggest the possibility of chronic toxic risk to honey bee larvae and the eventual stability of the hive."

But in April 2003, the EPA decided to give Bayer conditional registration. Bayer could sell the product and seed processors could freely use it, with the proviso that Bayer complete a life cycle study of clothianidin on corn by December 2004. Bayer was granted an extension until May 2005 (and permission to use canola instead of corn in its tests), but didn't complete the study until August 2007. The EPA continued to allow the sale of clothianidin, and once the Bayer study finally came out, it was flawed.

In a statement to the Pesticide Action Network, beekeeper Jeff Anderson explains:

"The Bayer study is fatally flawed. It was an open field study with control and test plots of about 2 acres each. Bees typically forage at least 2 miles out from the hive, so it is likely they didn’t ingest much of the treated crops. And corn, not canola, is the major pollen-producing crop that bees rely on for winter nutrition.

"This is a critical point because we see hive losses mainly after over-wintering, so there is something going on in these winter cycles. It’s as if they designed the study to avoid seeing clothianidin’s effects on hive health." [Emphasis ours]
And:
The new study, unearthed by Colorado beekeeper Tom Theobald, invalidates Bayer's previous study, claiming that "after another review of this field study in light of additional information, deficiencies were identified that render the study supplemental. It does not satisfy the guideline 850.3040, and another field study is needed to evaluate the effects of clothianidin on bees through contaminated pollen and nectar." The study also warns that clothiandin is highly toxic to bees on both a contact and oral basis.

And yet, the EPA is continuing to allow the sale of clothiandin, even though the study that the agency based its decision on proved to be invalid. "It's a matter of perspective," says Frazier. "If the core study to judge registration is no longer considered a valid core study, do you allow continued use of something without good scientific data behind it? That's the choice that's been left to be made by the EPA."

With the EPA's stellar performance record, do you think clothiandin will be taken off the market anytime soon?  Why won't the Environmental Protection Agency even pretend to protect the environment?  Will American society even pretend to care? 

Welcome to 2010:  We gladly kill what would save us.
