Honey Bee Die-off Alarms Beekeepers, Crop Growers, and Researchers
23 April 2007 - sciencedaily.com
| An alarming die-off of honey bees has beekeepers
fighting for commercial survival and crop growers wondering whether
bees will be available to pollinate their crops this spring and
summer. Researchers are scrambling to find answers to what's causing
an affliction recently named Colony Collapse Disorder, which has
decimated commercial beekeeping operations in Pennsylvania and across
the country. "During the last three months of 2006, we began to receive
reports from commercial beekeepers of an alarming number of honey bee
colonies dying in the eastern United States," says Maryann Frazier,
apiculture extension associate in Penn State's College of Agricultural
Sciences. "Since the beginning of the year, beekeepers from all over
the country have been reporting unprecedented losses. |

"This has become a highly significant yet poorly understood problem
that threatens the pollination industry and the production of
commercial honey in the United States," she says. "Because the number
of managed honey bee colonies is less than half of what it was 25
years ago, states such as Pennsylvania can ill afford these heavy
losses."
A working group of university faculty researchers, state regulatory
officials, cooperative extension educators and industry
representatives is working to identify the cause or causes of Colony
Collapse Disorder and to develop management strategies and
recommendations for beekeepers. Participating organizations include
Penn State, the U.S. Department of Agriculture, the agriculture
departments in Pennsylvania and Florida, and Bee Alert Technology
Inc., a technology transfer company affiliated with the University of
Montana.
"Preliminary work has identified several likely factors that
could be causing or contributing to CCD," says Dennis vanEngelsdorp,
acting state apiarist with the Pennsylvania Department of Agriculture.
"Among them are mites and associated diseases, some unknown pathogenic
disease and pesticide contamination or poisoning."
Initial studies of dying colonies revealed a large number of disease
organisms present, with no one disease being identified as the
culprit, vanEngelsdorp explains. Ongoing case studies and surveys of
beekeepers experiencing CCD have found a few common management
factors, but no common environmental agents or chemicals have been
identified.
Comment: No mention of radio, micro, or cellular
wave energy as of yet, or if they will be allowed to research it.
The beekeeping industry has been quick to respond to the crisis. The
National Honey Board has pledged $13,000 of emergency funding to the
CCD working group. Other organizations, such as the Florida State
Beekeepers Association, are working with their membership to commit
additional funds.
This latest loss of colonies could seriously affect the production of
several important crops that rely on pollination services provided by
commercial beekeepers.
"For instance, the state's $45 million apple crop -- the fourth
largest in the country -- is completely dependent on insects for
pollination, and 90 percent of that pollination comes from honey
bees," Frazier says. "So the value of honey bee pollination to apples
is about $40 million."
In total, honey bee pollination contributes about $55 million to
the value of crops in the state. Besides apples, crops that depend at
least in part on honey bee pollination include peaches, soybeans,
pears, pumpkins, cucumbers, cherries, raspberries, blackberries and
strawberries.
Frazier says to cope with a potential shortage of pollination
services, growers should plan well ahead. "If growers have an existing
contract or relationship with a beekeeper, they should contact that
beekeeper as soon as possible to ascertain if the colonies they are
counting on will be available," she advises. "If growers do not have
an existing arrangement with a beekeeper but are counting on the
availability of honey bees in spring, they should not delay but make
contact with a beekeeper and arrange for pollination services now.
"However, beekeepers overwintering in the north many not know the
status of their colonies until they are able to make early spring
inspections," she adds. "This should occur in late February or early
March but is dependent on weather conditions. Regardless, there is
little doubt that honey bees are going to be in short supply this
spring and possibly into the summer."
