The home honeybee (Apis mellifera), additionally incessantly spelled “honey bee” and recognized scientifically because the European or western honeybee, is the most typical of the 9 species of honey-producing bees. It’s native to Africa, Europe and the Center East, in response to the College of Arkansas Division of Agriculture, however people have launched home honeybees all over the world and it is the one honeybee in the USA.
Honeybees are social bugs. They dwell in massive colonies that embrace a single grownup queen bee and tens of hundreds of feminine employee bees, whose numbers change with the seasons, in response to the U.S. Meals and Drug Administration. The queen bee is the one bee that lays eggs. Male honeybees, known as drones, are solely seen in the course of the spring mating season and hatch from unfertilized eggs. The feminine employee bees, alternatively, hatch from eggs which have been fertilized by drones.

Beekeeping, or apiculture, is the human administration of honey bee colonies. The follow dates again to virtually 9,000 years in the past, in response to a 2015 paper printed within the journal Nature. Trendy beekeepers use human-made bee hives which are usually containers with rows of picket frames that bees fill with wax honeycomb. The hives are designed to offer beekeepers entry to gather honey and assist keep the nest.
Why honeybees are necessary
Honeybees produce a number of merchandise which are helpful to individuals, notably honey and beeswax. There’s a saying amongst beekeepers: “With a bee, you should use all the things however the buzz,” stated Sue Garing, a industrial beekeeper who owns and operates a honey enterprise in Kirkwood, New York.
Honeybees additionally present a invaluable service by pollinating flowers as they forage, thus serving to wildflowers reproduce and serving to farms yield extra and higher produce. Many frequent agricultural crops require pollination as a way to bear fruit or enhance the standard of the fruit. “When you have beehives [nearby], you will have higher fruit,” Garing advised Reside Science; she first acquired honeybees to assist her fruit bushes in upstate New York.

Honeybees have grow to be an necessary complement to native bee pollinators for a lot of crops, and important to manufacturing of some, reminiscent of almonds and avocados, in response to the Nationwide Honey Board. Right this moment, most of the largest industrial beekeepers transfer hives across the nation to pollinate crops — a service that is many beekeepers’ main supply of earnings, Garing stated.
Consultants stress that whereas honeybees are economically and ecologically necessary, there are round 20,000 different species of bees worldwide that additionally pollinate crops. “A few of these bees go to flowers that may solely be visited by them,” stated Margaret Couvillon, a pollinator biologist at Virginia Tech in Blacksburg, Virginia. “In the event you take that bee away, that flower may even disappear.”
For instance, in a 2014 examine printed within the journal Scientific Experiences, researchers describe how a species of solitary ground-nesting bee native to Japan has coevolved with a trumpet-shaped flower. The bee’s unusually lengthy tongue has made it crucial pollinator species for that specific flower.
How honeybees make honey
Some employee bees specialize as foragers, and so they journey comparatively far distances (round 4 miles, or 6.5 kilometers) for his or her tiny physique dimension searching for good meals sources, wrote pollinator specialist Joe Traynor, in his article on the beekeeping discussion board Beesource.
As soon as a honeybee finds a patch of flowers or fruit orchard, the bee returns to the colony to recruit different employees to go to the location by performing a “waggle dance.” The bee’s waggle dance is “a symbolic language giving a distance and path,” Couvillon stated. The dance gives all the knowledge the opposite bees want to search out the situation.

Honeybees collect nectar of their mouths, which collects in a honey crop, an inner organ often known as a honey abdomen. Pollen accumulates on the bee’s hind legs within the pollen basket, an indented space surrounded by hair.
Again on the hive, employees regurgitate the nectar and cross it amongst themselves in a series of regurgitated nectar-honey, till enzymes of their abdomen have damaged down the nectar into easy sugars. The nectar then will get dehydrated to include solely 18 to twenty% water, a course of aided by the fast wing flapping of the honeybees, in response to an article in The Dialog. As soon as the nectar has became honey and sufficiently dehydrated, the bees seal it in honeycomb chambers with a skinny layer of beeswax, which the bees produce themselves. The honey can stay edible for lots of of years due to its low moisture content material and pure antibacterial properties, Smithsonian Journal reported.
When nectar is in brief provide, some honeybees steal meals from different hives moderately than waste power foraging. Honeybees could also be significantly defensive at these occasions, known as a robbing season, stated Elina Niño, a beekeeping researcher on the College of California, Davis.
Honey is the primary foodstuff of employee bees, and colonies depend on stockpiles to outlive the winter, when foraging alternatives are slim. The opposite lessons of bees have specialised diets. For instance, employee and drone larvae eat extra pollen, which has a better protein content material to assist their bodily growth, Niño stated.
The follow of beekeeping
When a employee bee feels threatened, it could stick its venomous, barbed stinger into the risk. This motion is a final resort for the employee, because the stinger is then ripped out of the bee, killing the bee within the course of. To get across the bee’s painful protection mechanism, beekeepers could ship puffs of smoke into the hive and surrounding space, which interferes with the bees’ capability to detect one another’s alarm pheromones and stops them from stinging.

Honeybee conduct varies amongst colonies, Niño stated. Some honeybee colonies are not often defensive whereas others could also be poised to assault at any time. For instance, Africanized honey bees, a hybrid pressure of honeybees from Africa and Europe, are thought-about particularly defensive. “Africanized honey bees will reply quicker, in better numbers, and observe intruders for longer distances than European honey bees,” she stated.
Populations of Africanized bees have unfold northward via the Americas, from Brazil, after African honeybees have been launched there within the Fifties, in response to the Smithsonian Institute. Garing stated that if certainly one of her 50 hives is especially “scorching” (or overly aggressive), she is going to kill the queen and change it with a brand new one for the colony to assist, in an effort to assist the hive grow to be extra mellow. Queens are sometimes allowed to mate with any wild drones within the space, Garing defined, due to the problem and expense of selective breeding or synthetic insemination.
Honey bee merchandise
Folks eat and use many merchandise instantly produced by honeybees, reminiscent of honey and beeswax. The excessive sugar content material of honey makes it a fascinating candy deal with for many individuals, and the flavour is exclusive to the mix of flowers the bees acquire their nectar from. Beeswax is comprised of the bees’ glandular secretions that construct the hexagonal cells that function brooding and storage chambers within the hive. The product additionally has a number of human makes use of and is included in objects reminiscent of candles, skincare merchandise and cleaning soap.

There are various supposed medicinal makes use of of honey and different bee merchandise, reminiscent of propolis (a form of sealant that bees use to shore up holes of their nest and line the doorway to the hive) and royal jelly (one other sort of glandular secretion produced by nursery employees, or bees chargeable for taking good care of child bees). Garing additionally receives requests for bee brood, or bee eggs, larva and pupae, all of that are edible.
These merchandise are sometimes touted as new-age or conventional medication, and are stated to offer poorly-defined basic well being advantages. However regardless of the lengthy historical past of beekeeping, which predates Western medical science, the extent of many of those advantages and the potential explanations are usually not well-understood, as summarized in a 2017 evaluation printed within the journal Oxidative Medication and Mobile Longevity.
Threats to honeybees
The principle threats to the well being of a honeybee hive are generally grouped into what scientists name “the 4 Ps”: pesticides, pests, pathogens and poor vitamin.
A number of the largest issues going through honeybees within the U.S. embrace varroa mites, that are blood-sucking parasites that transmit illness; American foulbrood, a bacterial an infection that kills bee larvae; local weather change; and urbanization. These pressures have made beekeeping harder and dearer, and have contributed to a significant decline within the variety of managed beehives in the USA — from greater than 5 million within the Fifties to about 2.5 million lately, in response to a 2010 article within the journal Apidologie.

Whereas there are challenges to each industrial operations and yard beekeepers, honeybees are usually not at risk of extinction, specialists advised Reside Science. As an alternative, hundreds of native bee species, that are additionally necessary pollinators for a lot of wild and home crops however are sometimes solitary, and subsequently poor candidates for industrial rearing, are in additional dire want of assets and safety.
Completely different species of bees have totally different roles as pollinators, whether or not it’s specialised pollination that helps biodiversity, or massive scale agricultural crop pollination that feeds the world, Couvillon stated. For that cause, she stated, “we want each [native bees and honeybees] current within the panorama.”
