Beekeeper (apiarist) Henk Brouwer in Zwiggelte owns 30 bee colonies of which in winter 2012-2013 half have died. Since several years beekeepers worldwide confront massive death of bees in their bee hives. Bees are vital for the agriculture, 75% of the pollination of agricultural crops in the open field and in the greenhouses is done by bees. Apiarist Brouwer keeps his colonies at different locations: in his backyard surrounded by agriculture and also in a nature reserve on heathland. It is very hard to draw conclusions about the reasons of the massive death of the bees. Possible reasons could be the varroa (parasite), nosema (parasitic mould) or pesticides. The bees of these colonies did certainly not die from hunger.
