Beehive

A beehive is an enclosed structure in which honey bees raise their young and produce honey as part of their seasonal cycle. Although the word beehive is used to describe the nest of any bee colony, scientific and professional literature distinguishes nest from hive. Nest is used to discuss colonies that house themselves in natural or artificial cavities or in structures that are hanging and exposed. The term hive is used to describe a man made structure created to house a honey bee colony. While species of Apis live in colonies, the western (Apis mellifera) and eastern honey bees (Apis cerana) are the main species kept in artificial beehives.

The hive's internal structure is a densely packed group of hexagonal prismatic cells made of beeswax, called a honeycomb. The bees use the cells to store food (honey and pollen) and to house the brood (eggs, larvae, and pupae).

Beehives are used by humans for producing honey, ensuring pollination of crops, housing bees for apitherapy treatment, and mitigating the effects of colony collapse disorder. In North America, hives are commonly transported between farms so bees can pollinate various crops during their specific blooming periods.

Several patents have been issued for beehive designs.

Honey bees use caves, rock cavities, and hollow trees as natural nesting sites. In warmer climates, they may build exposed hanging nests; members of other subgenera have exposed aerial combs. Multiple parallel honeycombs form the nest with a relatively uniform bee space. Nests typically have a single entrance. Western honey bees prefer nest cavities approximately 45 L (1.6 cu ft) in volume and avoid those smaller than 10 L (0.35 cu ft) or larger than 100 L (3.5 cu ft). Western honey bees show several nest-site preferences: the height above ground is usually between 1 metre (3.3 ft) and 5 metres (16 ft), entrance positions tend to face downward, equatorial-facing entrances are favored, and nest sites over 300 metres (980 ft) from the parent colony are preferred. Most bees occupy nests for several years.

The bees often smooth the bark surrounding the nest entrance and coat the cavity walls with a thin layer of hardened plant resin called propolis. Honeycombs are attached to the walls along the cavity tops and sides, but the bees leave passageways along the comb edges. The standard nest architecture for all honeybees is similar: honey is stored in the upper part of the comb; beneath it are rows of pollen-storage cells, worker-brood cells, and drone-brood cells, in that order. The peanut-shaped queen cells are normally built at the lower edge of the comb.

In antiquity, Egyptians kept bees in manmade hives. The walls of the Egyptian sun temple of Nyuserre Ini from the 5th Dynasty, dated earlier than 2422 BCE, depict workers blowing smoke into hives as they remove honeycombs. Inscriptions detailing honey production are found on the tomb of Pabasa from the 26th Dynasty (c. 650 BCE), and describe honey stored in jars and cylindrical hives.

The archaeologist Amihai Mazar cites 30 intact hives that were discovered in the ruins of Tel Rehov, located in modern-day Israel. This is evidence that an advanced honey industry existed in Canaan approximately 4,000 years ago. The 150 beehives, many broken, were made of straw and unbaked clay. They were found in orderly rows. Ezra Marcus from the University of Haifa said the discovery provided a glimpse of ancient beekeeping seen in texts and ancient art from the Near East. An altar decorated with fertility figurines was found alongside the hives and may indicate religious practices associated with beekeeping. While beekeeping predates these ruins, this is the oldest apiary yet discovered.
