Varroa destructor mites are the most significant threat to managed honeybee colonies globally. Their impact on individual bee health and colony survival makes varroa management a central welfare concern in apiculture.
The welfare of individual honeybees within a managed colony is complex - bees are eusocial insects whose individual significance is inseparable from their colony context. However, varroa infestation causes clear harm at both individual and colony levels: infested bees emerge with physical deformities, shortened lifespans, and impaired foraging ability; infested colonies decline, become nutritionally stressed, and ultimately collapse. Effective varroa management is therefore both a welfare and a beekeeping production imperative. The development of treatment-resistant mite populations makes investment in breeding for natural resistance increasingly urgent.
