The first survey of bee
health this year revealed a grim picture, with 36.1 percent of the nation's commercially managed hives
collapsing - a 13.5 percent increase over 2007. As beekeepers travel with their
hives this spring to pollinate crops around the country, it's clear the
bees themselves are buckling under the weight of new diseases, pesticide drift
and old enemies like the parasitic varroa mite, said Dennis vanEngelsdorp,
president of the Apiary Inspectors of America, which commissioned the survey
released Tuesday. This is the second year the association has measured colony
deaths across the country. This means there aren't enough numbers to show a
trend, but clearly bees are dying at unsustainable levels and the situation is
not improving, said vanEngelsdorp, also a bee expert with the Pennsylvania
Department of Agriculture. "For
two years in a row, we've sustained a substantial loss," he said.
"That's an astonishing number. Imagine if one out of every three cows, or
one out of every three chickens, were dying. That would raise a lot of
alarm."
The survey included 327 operators, or 19 percent of the
country's approximately 2.44 million commercially managed bee hives. The data
is being prepared for submission to a journal. Most of the bee deaths - 71 percent - were not due to
Colony Collapse Disorder, a mysterious disease that causes adult bees to
abandon their hives. But when hives show symptoms of the ailment - when
bees completely abandon a hive that otherwise looked healthy - a large
percentage of a keeper's hives are wiped out. Bee operations that noticed these
symptoms had a total loss of 41.3 percent of their colonies. Beekeepers who did
not find signs of colony collapse lost an average of 17.5 percent of their
hives. This combination of factors highlights the need for more research, not
only into CCD, but into pollinator health in general, said vanEngelsdorp. On
Tuesday, Pennsylvania's Agriculture Secretary Dennis Wolff announced that the
state would pour an additional $20,400 into research at Pennsylvania State
University causes of Colony Collapse Disorder. This raises emergency funds
dedicated to investigating the disease to $86,000. looking for
