Honey bees, like all other living things, vary among themselves in traits such as temperament, disease resistance, and productivity.
The environment has a large effect on differences among bee colonies (for example, plants in different areas yield different honey crops), but the genetic makeup of a colony can also impact the characteristics that define a particular group.
The term "stock" is defined as a loose combination of traits that characterize a particular group of bees. Such groups can be divided by species, race, region, population, or breeding line in a commercial operation.
Many other honey bee stocks are worth noting:
Numerous hybrid stocks are also available commercially:
Bee differences can be used to advantage by beekeepers, depending on what traits interest them, so using different stocks can be a powerful tool at the beekeeper's disposal.
