Summary  Recapping of  Varroa destructor ‐infested brood cells is a trait that has recently attracted interest in honey bee breeding to select mite‐resistant  Apis mellifera  colonies. To investigate the genetic architecture of this trait, we evaluated a sample of  A .  mellifera mellifera  colonies ( N  = 155) from Switzerland and France and performed a genome‐wide association study, using a pool of 500 workers per colony for next‐generation sequencing. The results revealed that two QTL were significantly ( P  < 0.05) associated with recapping of  V. destructor ‐infested brood cells. The best‐associated QTL is located on chromosome 5 in a region previously found to be associated with grooming behaviour, a resistance trait against  V. destructor , in  A .  mellifera  and  Apis cerana . The second best‐associated QTL is located on chromosome 4 in an intron of the  Dscam  gene, which is involved in neuronal wiring. Previous research demonstrated that genes involved in neuronal wiring are associated with recapping and varroa sensitive hygiene. Therefore, our study confirms the role of a gene region on chromosome 5 in social immunity and simultaneously provides novel insights into genetic interactions between common mite resistance traits in honey bees.
