Which honeybee is recognized for its heavy production of propolis?

The honeybee recognized for its heavy production of propolis is Apis mellifera caucasia. This variety, also known as the Caucasian honeybee, is known for its ability to gather and utilize resin from trees, which is essential for propolis production. Propolis is a resin-like material made by bees from plant resins, wax, and other substances, and is used to seal gaps in the hive, protect it from pathogens, and enhance hive hygiene.

Apis mellifera caucasia tends to have a stronger inclination to collect propolis compared to other subspecies, making it particularly valued for its ability to maintain clean and well-sealed hives. This characteristic contributes to the overall health of the colony, as propolis possesses antimicrobial properties that can help protect the hive from diseases and parasites.

In contrast, while other subspecies may produce propolis, they do not demonstrate the same level of productivity or preference for resin gathering, which is particularly pronounced in the Caucasian honeybee.
