The Different Types of BEES Honey bees, like all other living things, vary among themselves in traits such as temperament, disease resistance, and productivity. The environ- ment 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. Beekeepers have long known that different genetic stocks have distinctive characteristics, so they have utilized different strains to suit their particular purpose, whether it be pollination, a honey crop, or bee production.

What is a bee stock? Wide variation exists within stocks The term “stock” is defined as a loose as well as among them. Any generali- combination of traits that characterize a ties about a particular stock should be particular group of bees.
