Which race of honeybee is known for its gentle demeanor and high productivity?

The race of honeybee recognized for its gentle demeanor and high productivity is Apis mellifera carnica, commonly known as the Carniolan honeybee. This specific breed is known for its calm nature, making it easier for beekeepers to manage compared to more aggressive strains. Additionally, Carniolan bees are highly productive, particularly in colder climates, as they exhibit excellent foraging ability and are quick to build strong colonies.

In contrast, the other options do not align with the characteristics mentioned in the question. The Africanized honeybee (Apis mellifera scutellata), for example, is known for its aggressive behavior. Similarly, Apis mellifera caucasia, while gentle, does not have the same level of productivity or resilience in diverse environments as the Carniolan. Apis mellifera linguistica is not widely recognized among the popular races and does not have notable features that correspond with gentleness and productivity. Understanding these specific traits can help both beginning and experienced beekeepers choose the right race for their needs and local conditions.
