The Bee Informed Partnership (http://beeinformed.org), in collaboration with the Apiary
Inspectors of America (AIA) and the United States Department of Agriculture (USDA),
is releasing preliminary results for the seventh annual national survey of honey bee
colony losses. For the 2012/2013 winter season, a total of 6,287 U.S. beekeepers
provided validated responses. Collectively, responding beekeepers managed 599,610
colonies in October 2012, representing about 22.9%1 of the country’s estimated 2.62
million colonies.
Preliminary survey results indicate that 31.1% of managed honey bee colonies in the
United States were lost during the 2012/2013 winter. This represents an increase in loss
of 9.2 points or 42% over the previous 2011/2012 winter’s total losses that were
estimated at 21.9% (Figure 1). This level of loss is on par with the 6 year average total
loss of 30.5%2.
On average, U.S. beekeepers lost 45.1% of the colonies in their operation during the
winter of 2012/2013. This is a 19.8 point or 78.2% increase in the average operational
loss compared to the previous winter (2011/2012), which was estimated at 25.3%. The
difference between average loss and total loss is explained by the respondent pool: while
a majority of the respondents (95%) were backyard beekeepers, they managed a small
fraction of the colonies represented in the survey (6%). For this reason total loss (which
is more heavily influenced by commercial beekeeper losses) is more representative of
national losses.
Survey participants indicated that they considered a loss rate of 15% as “acceptable,” but
70% of them suffered losses greater than this.

I keep bees and belong to a local beekeepers group. Every one of us in the group has had major losses of up to 50%over the past 5 years due to CCD, varroa mites, neonictinoids from pesticides, and even cell phone signals have been known to throw the bees off their game. They have recently even discovered zombie bees among beeekeepers in VT which become afflicted through fly bites. Beekeeping is tiring but rewarding profession or hobby. Billions of people depending on the honey bee for the food on their table. This die off has serious implications for every human.
