The Research Network for Sustainable Bee Breeding is the task force dedicated to breeding and conservation within COLOSS.
This task force aims to improve honey bee health by considering the bees’ genetic origin and how they interact with the surrounding environment. We believe that the native honey bee populations represent an important resource for breeding gentle and productive bees adapted to environmental challenges. The ultimate aim of our group is to improve honey bee welfare by developing and disseminating comprehensive breeding strategies that include colony vitality and the conservation of locally adapted populations.
The Western honey bee, Apis mellifera L., is a diverse species, with 26 currently recognized subspecies reflecting the wide variety of ecosystems in its native range of Africa, Europe, Western and Central Asia. Studies of honey bee biodiversity were initiated in the 20th century, with outstanding contributions of two significant personalities: Brother Adam (1898-1996), who collected bees from across the world in search of the “perfect bee???, and Friedrich Ruttner (1914-1998), a scientist who published the work of his lifetime in the comprehensive monograph “Biogeography and taxonomy of honeybees??? (1988). This volume is still considered an important reference manual for anyone studying honey bee diversity, but more recently, increasing evidence from molecular methods has added to the picture.
Among the 12 subspecies of honey bees native to Europe, many are being subject to intense pressures from human activities. Meeting the demand for high economic performance, selective breeding for traits of commercial interest is concentrated in two subspecies (A. m. carnica and A. m. ligustica) only. This fact has in many regions led to the replacement of native subspecies by non-native bees. Commercial production of queens, migratory beekeeping and a free market permitting the trade of honey bees with no limitations on genetic origin, are additional factors endangering native honey bee populations. This phenomenon does not only signify the loss of natural heritage and diversity, but may also exacerbate colony health problems and losses.
We believe that the safeguarding of bee biodiversity, beyond its ethical and scientific dimensions, is also of high economic interest, because in the long run locally adapted populations are better suited than imported ones to cope with prevailing environmental conditions and health threats, and thus to survive. We have observed this in the pan-European experiment.
We therefore recognise the strong need to preserve local adaptation all over Europe: to achieve this we must encourage regional breeding efforts and find support to maintain local strains of bees in conservation apiaries.
Our working approach includes cooperation, exchange of ideas and mutual support, in a positive and friendly atmosphere. Our ambitious aim is to disseminate and implement sustainable breeding strategies on a global level, and to achieve this we will welcome new ideas and contributions that are in line with our constructive approach.
