COLOSS SURVEY 2021

Thanks to all beekeepers who completed the COLOSS Survey 2021. The Survey is now CLOSED for this year.

The National Apiculture Programme is co-funded by the Department of Agriculture, Food and the Marine and the European Union Under the National Apiculture Programme 2020-2023. The current Programme is based in University College Dublin.

The global decline of managed honeybee colonies (Apis mellifera L.) and high winter mortalities are a serious threat ecologically and economically. Winter colony losses in Ireland remain one of the highest in Europe, frequently exceeding 20%, and sometimes greater than 30%. The reasons for these losses are unclear, but factors including operation size, beekeepers’ experience, insufficient control of Varroa, age/quality of queens and forage sources are possible causes.
