Health Status of Honeybee Colonies Differing in Genetic Intra-Colonial Diversity

Abstract Two different levels of diversity within a colony were compared for the prevalence pathogens and diseases. Lower genetic was obtained in colonies which queens inseminated with semen collected from drones originating single colony, while greater thirty colonies. Bees tested Varroa destructor infestation, microsporidia Vairimorpha spp. infection, acute bee paralysis virus (ABPV) deformed wing (DWV). Colonies workers more infested mites than genetically uniform infestation not found to be associated directly weakening after winter. The two experimental groups had similar number infected , viruses. Intensity infection did significantly affect overwintering DWV detected weakened during overwintering.
