Heritability of hygienic behavior in grey honey bees (Apis mellifera carnica) [PDF]
Acta veterinaria, 2008 Breeding grey A. m. carnica queens for hygienic behavior is beneficial for commercial beekeeping in Serbia, since hygienic behavior is associated with the resistance to the mite Varroa destructor, as well as to American foulbrood and chalk brood. In this work, heritability of hygienic behavior was analyzed in autochthonous grey A. m. carnica honey bees

Pathogen and Hemocyte Dynamics in Three Apiaries Across a Bee Season
Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.Honey bees are dying due to a disease complex consisting of viruses, parasites, chemicals, nutritional deficiencies, and management problems. In the present study, pathogens and hemocytes were analyzed in honey bee hemolymph samples using third‐generation sequencing and flow cytometry in three apiaries over a honey bee season. Using nanopore sequencing,
