Abstract

Beekeeping started in ancient times when the first humans naturally killed the swarms nesting in tree and stone hollows and utilized their honey. Beekeeping, which was practiced with primitive methods until a few years ago, has developed up to today's modern beekeeping in the light of scientific discoveries and developments. There are approximately 56 million beehives worldwide and 1.2 million tons of honey is produced from these hives. For this reason, honey is seen as a foodstuff that the first people meet their need for sugar, easy to digest, and quickly mixed into the blood. In addition, materials such as pollen, propolis, bee venom, and beeswax obtained from beekeeping have a very important place in health and industrial fields. However, there are not enough resources to guide today's beekeepers both for beekeeping and for bees and bee products in our country and in the world. Within the scope of this study, the historical development of beekeeping, beekeeper's calendar, hive types and sizes, honey harvesting and hive care, bee products, etc. It aims to give an overview to people interested in beekeeping.

Keywords
