In the period of 12.5.-16.5.2022 Bjørn Dahle and Camillia Sundby from the Norwegian Beekeepers Association came to Croatia to visit the “deep forest” and flatland mating stations run by the Centre for applied life sciences Healthy food chain Ltd. for research and development (CALIS). With their experience in controlled mating of queen bees, during the implementation of the BeeConSel project, we aim to improve mating control in all tree beneficiary countries – Croatia, Macedonia and Slovenia.
