A leaked document shows the EPA under the Bush administration approved the pesticide clothianidin for widespread use on many crops, including corn, despite the findings from EPA scientists that it was a bee-killer.
It may be responsible for the recent "Honeybee Depopulation Syndrome,"
which has been negatively affecting agriculture throughout North America. Previously.
The NYTimes covers the mysterious collapse of commercial honeybee colonies over the last 5-months, covering dozens of states
. The disease, Colony Collapse Disorder
, does not have a determined cause. The Canary Database
indicates that bees
can serve as "canaries in a coalmine" for human diseases
, as many other animals do. Some of the suspected causative agents (as reported [pdf
] by Penn State
) include a immunodeficiency, the hive consumption of high-fructose corn syrup, nutritional stress, parasites, infectious diseases, stress due to colony splitting and relocation, insecticides, and antibiotic use. The die-offs are likely to adversely impact both prices and crop yields
"Bees are in grave danger. So is our food supply. Why something so small matters so much."
Where have all the bees gone?
Wild bee populations appear to be declining (members of a local naturalists' mailing list I subscribe to report seeing substantially fewer bumblebees in recent years), and domestic honeybees are susceptible to mites. Since one third of our crops require pollination, this is not just an environmental concern but also a very real threat to our food supply. Find out what's being done about it. Fascinating stuff, if a little frightening.
Pollination Pets for the Garden.
The UK bee population has almost halved in the last 10 years due mainly to the spread
of a mite called Varroa
from Asia. The loss of such a large proportion of the bee population has implications for agriculture, horticulture and nature, bees pollinate the majority of plants with no intervention from man, there isn't a more reliable fertilisation method.
However an Oxford company has come up with a simple kit
to attract Mason bees to nest in your garden requiring no effort and no protective clothing, they're pretty docile too, so it's unlikely you'll get stung.
BTW, the US
is affected too.
