Studies link pesticides to plunging bee populations

British researchers, meanwhile, found that bumblebee colonies exposed to common levels of another pesticide from the same family grew more slowly and produced nearly 85% fewer queens than non-exposed colonies, "which clearly could have very strong implications for bumblebee populations in the wild," co-author Dave Goulson said Thursday in Paris.
"I would suggest that there is a need to urgently re-evaluate the use of these pesticides on flowering crops," said Goulson, a biology professor at the University of Stirling in Scotland.

The studies released Thursday are the latest to point to neonicotinoid insecticides, which are often used to treat seeds for cereals and some flowering crops like corn, as a factor in plunging bee populations. The chemicals mimic the effect of the tobacco ingredient nicotine, which is used as a natural insecticide, and pose less risk to humans and other mammals.

This is interesting that they have now found solid proof of something that has destroyed bee colonies in observed tests.. and would explain why it's happening mainly in the West and around large agricultural centers.

Another ... erm .. interesting tidbit.. Monsanto happens to be the largest producer of neonicotinoid insecticides, and in the few places that have banned the substance Monsanto has often led the lobbying group to have he rules overturned. Such as Slovenia who in 2003 after bee colonies began collapsing banned the substance .. Monsanto later had it overturned.

Coincidence? I think not.

After researching a little more I found that Monsanto is actually the second largest producer.. Bayer corporation is the largest producer of neonicotinoids.

Bedfellows with Monsanto and Bayer, the USDA will most likely never publish the
study they did, the truth be told, the Neonicotinoids are harmful even in minute exposure
to the bees.


The American study ... has demonstrated that the insects’ vulnerability to infection is increased by the presence of imidacloprid, even at the most microscopic doses. Dr. Pettis and his team found that increased disease infection happened even when the levels of the insecticide were so tiny that they could not subsequently be detected in the bees, although the researchers knew that they had been dosed with it.

the lead researcher at the USDA’s very own Bee Research Laboratory completed research two years ago suggesting that even extremely low levels of exposure to neonicotinoids makes bees more vulnerable to harm from common pathogens.



So why on earth are they still in use on million of acres of American farmland?

If this is true (there were other suggested explanations for the bee plague), and the pesticide can be identified, the manufacturer could be sued beyond all comprehension - and maybe also the govts that allowed this pesticide to be used. The extermination of the honey bees wrecked the pollination of plants and crops and doomed a number of flowering species to extinction. What we feared would be the result of acid rain or some such turned out to be the byproduct of deliberate spraying.

Some thoughts, the bees are our Sixth Extinction.



www.aloelf.com...


Honey bee and pollinator decline indicates a “sixth major extinction” of biological diversity is currently underway, caused by habitat loss, pollution, pest invasion, and disease, leading to ecosystem havoc vital to human livelihood.

Current evidence demonstrates that a sixth major extinction of biological diversity
event is underway.

1. The Earth is losing between one and ten percent of biodiversity
per decade

2, mostly due to habitat loss, pest invasion, pollution, over-harvesting and
disease

3. Certain natural ecosystem services are vital for human societies.
Many fruit, nut, vegetable, legume, and seed crops depend on pollination.

Pollination services are provided both by wild, free-living organisms (mainly bees,
but also to name a few many butterflies, moths and flies), and by commercially
managed bee species. Bees are the predominant and most economically important
group of pollinators in most geographical regions.

The Food and Agriculture Organisation of the United Nations (FAO)4 estimates that
out of some 100 crop species which provide 90% of food worldwide, 71 of these
are bee-pollinated.

In Europe alone, 84% of the 264 crop species are animalpollinated
and 4 000 vegetable varieties exist thanks to pollination by bees5. The
production value of one tonne of pollinator-dependent crop is approximately five
times higher than one of those crop categories that do not depend on insects.

So, what is the end here, with endangered honey bee's?

Monsanto and the GMO bees? Seriously, folks this is looking rather bleak.
