The Research Network for Sustainable Bee Breeding was founded on April 5th 2013 on the Croatian island Unije. The foundations for the group date back to 15 years ago when a first survival experiment involving several European genetic origins took place. In 2004, during the first European conference of Apidology (EURBEE) a group of scientists involved in honey bee breeding decided to create the Eurbee Breeding Group, with the aim of exchanging experience and of harmonising breeding methods. With the start of the COST action “Prevention of honey bee colony losses” (COLOSS), part of the breeding group became “working group 4” of COLOSS, as we believed that Diversity and Vitality of honey bees could have an impact on the performance and survival of the colonies. The contribution of WG4 to the COST action was to perform a pan-European experiment. With completion of the COST action and the experiment we decided that we wanted to join the positive experiences and spirit of the group and that is how the RNSBB emerged, and is now the task force dedicated to breeding and conservation within the new registered association COLOSS.
