Commercial honey bees trucked across the United States for crop pollination face significant colony-level welfare stresses that contribute to high mortality rates and colony collapse disorder.
The welfare of commercial honey bees is a colony-level phenomenon: individual bees have brief lives, but colony survival and health represent the welfare unit. Commercial pollination creates concentrated stress - colonies arrive nutritionally depleted from winter, are exposed to novel pathogens from other commercial colonies, and face pesticide exposure in agricultural landscapes. The chronic high loss rates reflect a system pushing colonies beyond sustainable thresholds. Reform requires both better hive management practices and agricultural policy changes to create more pollinator-friendly landscapes.
