The Pan-European Genotype-Environment-Interactions Experiment
An international experiment to estimate the importance of genotype-environment interactions on vitality and performance of honey bees and colony losses was run between 2009 and 2012. The experiment included 621 starting colonies from 16 different genetic origins belonging to 5 Apis mellifera subspecies (carnica, ligustica, macedonica, mellifera, siciliana). It took place in 21 beeyards, managed by 15 COLOSS partners in 11 European countries, ranging from Scandinavia to the Mediterranean, and across Central Europe to the Balkans.
At each location, the local strain of bees was tested together with at least two “foreign
