The honey bee protection network, COLOSS1, announced the preliminary results of an international study to investigate honey bee winter colony losses earlier this month. Data were collected from Israel and Algeria and 19 European countries. In total 17,135 respondents provided overwintering mortality and other data of their honey bee colonies.
Collectively, all responding beekeepers managed more than 376,754 colonies. A preliminary analysis of the data show that the mortality rate over the 2013-14 winter varied between countries, ranging from 6% in Norway to 14 % in Portugal, and there were also marked regional differences within most countries. The overall proportion of colonies lost was 9 %, the lowest since the international working group started collecting data in 2007.
Last winter also saw a decrease in overwintering losses for honey bee colonies being reported for England and Wales and the USA.
