Colony Collapse Disorder
“If the bee disappeared off the surface of the globe, then
man would have only four years of life left. No more bees, no more pollination,
no more plants, no more animals, no more man” Albert Einstein
The Colony Collapse Disorder (CCD) is the name used for the
rapid declination of honey bees all across the world. ‘The issue was first
raised in October 2006 where beekeepers in the United states recorded losses
somewhere between 30-90% of their hives’. There is no known reason for why the
CCD has occurred. Major contributing factors to the decrease of the Honey Bees
have been broaden down into four main categories; pathogens, parasites,
management stressors, environmental stressors.
-Pathogens: There is no specific pathogens that can be
pointed out as the direct reason for CCD but there is a few major pathogens
that account for a loss in honey bees. The pathogens are a mix of fungal,
bacterial and viral diseases.
-Parasites: One of the main problems in the decline in honey
bees and the infestation of bee hives is Varroa Mites the only organism
responsible in the CCD.
-Management Stressors: The increase of honey bees in a
certain area can bring on overcrowding of a bee hive and the migratory stress of
bees being relocated to other bee hives.
-Environmental Stressors: The stress that environmental
factors have on bees also can be correlated to the CCD. One of the major issues
is pesticides used for protecting agricultural environment that require
pollination resulting in large numbers of bees dying. Also the lack of pollen
diversity and lack of pollen create environmental stress. Contaminated water
also another reason for the decline in bees.

Here we can see a healthy bee population in figure 1, but as
the years go on polloution, disease and the unknown cause of the colony
collapse disorder, shows the rapid decline in colonies over time.
