Wild bee populations have declined dramatically, facing cumulative welfare impacts from pesticide exposure, pathogen spillover from honeybees, habitat loss and climate change.
Wild bee welfare encompasses both individual and population-level concerns. Individual bees exposed to sublethal pesticide concentrations suffer impaired cognition and navigation that causes increased mortality through getting lost and reduced foraging success. Pathogen-infected bees show reduced flight, abnormal behaviour and shortened lifespan. The scale of wild bee decline means this individual suffering is multiplied across billions of individuals. Welfare improvement requires habitat restoration (diverse, pesticide-free flowering plants), pesticide reform (restricting neonicotinoids on flowering crops), and thoughtful apiculture that minimises disease spillover to wild populations through management standards.
