Colony
Collapse Disorder
Honey bees are a critical link in U.S.
agricultural production. Pollination by managed honey bee colonies adds at
least $15 billion to the value of U.S. agriculture annually through
increased yields and superior-quality harvests. But managed honey bees
have come under serious pressures from many different stresses, which has
resulted in beekeepers losing many colonies.
One problem plaguing honey bees since
2006 has been Colony Collapse Disorder (CCD), which is a syndrome
specifically defined as a dead colony with no adult bees and with no dead
bee bodies, but with a live queen, and usually honey and immature bees,
still present. CCD is not a general term that covers all managed honey bee
colonies that are lost due to any reason. No scientific cause for CCD has
been proven. Most research has pointed to a complex of factors being
involved in the cause of CCD, and possibly not all of the same factors, or
the same factors in the same order, are involved in all CCD incidents.
CCD is far from the only major threat
to the health of honey bees and the economic stability of commercial
beekeeping in the United States. In fact, the number of managed colonies
that beekeepers have reported losing specifically from CCD began to wane
in 2010 and has continued to drop. But the beekeeping industry continues
to report losing a high percentage of their colonies each year to other
causes.
Major factors threatening honey bee
health can be divided into four general areas: parasites and pests,
pathogens, poor nutrition, and sublethal exposure to pesticides. In
reality though, these factors tend to overlap and interact with one
another, which complicates issues. In addition, there are other issues
that have impacts on honey bee health such as the narrow genetic base of
honey bees in the United States.
Best Recommendations for the
Public
The best action the public can take to
improve honey bee survival is not to use pesticides
indiscriminately. In
particular, the public should avoid applying pesticides during mid-day
hours, when honey bees are most likely to be out foraging for nectar and
pollen on flowering plants.
In addition, the public can plant
pollinator-friendly (for butterflies, too) plants that are good sources of
nectar and pollen such as red clover, foxglove, bee balm, joe-pye weed,
and other plants.
I knew next to nothing about the
feeding and nutrition needs of the honeybee until i visited Michigan
University College of Natural Science
Pollinator Science Initiative online.
It states that : "honey bees, like
all other animals, require essential ingredients for survival and
reproduction. Most of what we know about honey bee nutrition was learned
from the 1950s through the 1970s; only during the last few years have we
started to pay attention to honey bee nutrition again. Honey bees require
carbohydrates (sugars in nectar or honey), amino acids (protein from
pollen), lipids (fatty acids, sterols), vitamins, minerals (salts) and
water. Additionally, these nutrients must be present in the right ratios
for honey bees to survive and thrive."
