The varroa mite (Varroa destructor) belongs to the major threat of colonies of the western honey bee (Apis mellifera) worldwide. A sustainable approach to control the mite population in a honey bee colony is by breeding varroatolerant honey bees. In the SETBie project beekeepers, beekeeper associations and various university institutions are working together to breed and establish a varroa tolerant honey bees in Baden-Württemberg via the behavioural trait Varroa Sensitive Hygiene (VSH). Bee colonies with this trait specifically remove varroa infested brood cells and thus reduce the mite density within a colony. The project investigates the breeding trait VSH from genetic, methodological and beekeeping aspects.
