Advanced review of honey bee and bumble bee welfare, including colony management, pesticide impacts, and parasitism.
Bee welfare operates at both individual and colony levels. Individual bees show nociception and behavioural indicators of negative emotional states. Colony-level welfare includes freedom from disease, parasitism, and environmental stressors. Varroa management, pesticide exposure, and colony manipulation all affect welfare across multiple levels simultaneously. Advanced bee welfare considers these multiple scales rather than treating bees as interchangeable units.
