Losses of honey bee colonies over the 2012/13 winter
19.07.2013

PRESS RELEASE from the COLOSS Network

The honey bee research network COLOSS1 has today announced the preliminary results of an international study to investigate winter colony losses. Data were collected from 19 countries from Europe, Israel and Algeria. In total, more than 15,000 beekeepers provided overwintering mortality and other data of their colonies. Collectively, they managed more than 280,000 colonies. A preliminary analysis of the data shows that the mortality rate over the 2012-13 winter varied between countries, ranging from 6% in Israel to 37% in Ireland, and there were also marked regional differences within some countries. These figures compare with losses over the same period of 31% and 34% recently reported from the USA2 and the UK3 respectively.
