The Canadian Association of Professional Apiculturists (CAPA) has just issued its final report on overwintering losses of honey bees in Canada, and the picture is not a pretty one — although New Brunswick beekeepers fared a bit better than we have in the past few years.
Nationwide honey bee losses of 35% over the winter of 2007-2008 are up from last year’s mortality rate of 29% of colonies, and more than double the long-term “normal” of 15% that Canadian beekeepers were accustomed to seeing before the arrival of the Varroa destructor mite in this country.
