What is the term for a group of bee colonies kept for honey production and crop pollination?

The term for a group of bee colonies that are managed together for purposes like honey production and crop pollination is "apiaries." An apiary typically consists of multiple hives and is designed to facilitate the care and management of bees, allowing the beekeeper to effectively manage the colonies. This can involve activities such as inspecting for diseases, collecting honey, and ensuring effective pollination in nearby crops.

The other terms listed describe different aspects of beekeeping but do not encapsulate the concept of a collective group of colonies in the same way. A hive refers specifically to the structure containing a colony of bees. A colony denotes the actual population of bees within a hive. Pollinator farms suggest a focus on a broader integration of various pollinating species or practices, rather than specifically addressing the collective grouping of bee colonies. Therefore, "apiaries" is the most accurate term for a collection of hives managed for honey and pollination purposes.
