Colony Collapse Disorder
Colony Collapse Disorder
) is a little-understood phenomenon in which worker bees from a beehive or Western honey bee colony abruptly disappear. CCD was originally found in Western honey bee colonies in North America in late 2006. European beekeepers observed a similar phenomenon. Possible cases of CCD have also been reported in
Taiwan since April 2007.
From 1971 through 2006, there was a dramatic reduction in the number of feral (wild) honeybees in the US (now almost absent);
and a significant, though somewhat gradual decline in the number of
colonies maintained by beekeepers. This decline includes the cumulative
losses from all factors such as urbanization, pesticide use, tracheal and Varroa mites, and commercial beekeepers retiring and going out of business. However, late in the year 2006 and
in early 2007 the rate of attrition was alleged to have reached new
proportions, and the term "Colony Collapse Disorder" was proposed to
describe this sudden rash of disappearances
Limited occurrences resembling CCD have been documented as early as
1896, and this set of symptoms has in the past several decades been
given many different names (disappearing disease, spring dwindle, May disease, autumn collapse, and fall dwindle disease). Most recently, a similar phenomenon in the winter of 2004/2005 occurred, and was attributed to Varroa mites
(the "Vampire Mite" scare), though this was never ultimately confirmed.
Nobody has been able to determine the cause of any past appearances of
Upon recognition that the syndrome does not seem to be
seasonally-restricted, and that it may not be a "disease" in the
standard sense — that there may not be a specific causative agent — the syndrome was renamed.
cause (or causes) of the syndrome is not yet well understood. Theories
include environmental change-related stresses, malnutrition, pathogens
(i.e., disease including Israel acute paralysis mites, pesticides such
as neonicotinoids or imidacloprid, radiation from cellular phones or
other man-made devices", and genetically modified (GM) crops with
pest control characteristics such transgenic maize. Since 2007, the Israel acute paralysis virus or IAPV is under increased scrutiny as the leading suspect having been identified in 25 of 30 collapsed hives in one study and 96% in another.
So says Wikipedia
Louisiana has not experienced CCD to any significant extent. Bees are plentiful and productive.
