A drone congregation area is an aerial region where honeybee drones and virgin queens gather to mate.
A drone congregation area is an aerial region where honeybee drones and virgin queens gather to mate.
Drone congregation areas are typically about 100 metres (300 ft) in diameter and 15–30 metres (50–100 ft) above ground. They have the shape of an upward-pointing cone, with the drone density being lower towards the top. [1] The boundaries are sharply defined: drones will not mate with queens even slightly outside the area. [2]
Over the course of a day, approximately 12,000 drones visited one drone congregation area, [3] and the drones represented at one can be from hundreds of different colonies. [4] However, these population numbers are highly variable depending on circumstances. [5]
It is not known exactly why drone congregation areas have the locations they do, or how bees locate them. [6] [7] [8] However, there is considerable evidence that they depend on static features of the landscape. Drones will congregate in these areas even in the absence of queens, and stay in similar areas year-to-year, [9] with one drone congregation area staying in the same location for almost 200 years. [10] Additionally, if drones are brought in from outside the local area, they still quickly find the local congregation areas. [10]
Most drone congregation areas are open spaces surrounded by a barrier; the open area provides visibility while the barrier (vegetation, hills, etc.) provides shelter from the wind. [2] The bees also tend to fly to low elevations. [11] [12] South-facing locations are also preferred in the Northern hemisphere; this may be due to differences in solar irradiance or the bees' magnetoreception. [13]
Drones find their way to drone congregation areas along flyways, specific shared trajectories. These generally follow features in the landscape, such as lines of trees. Drone congregation areas often occur at the intersection of flyways, though not all intersections form congregation areas. [1] Flyways, like drone congregation areas, are stable over a period of years. [7]
Pheromones also play a role in coalescing drones to the exact location of the queen. The International Bee Research Association's standard procedure for locating drone congregation areas involves using a queen or a (pheromone-marked) dummy queen to attract drones from the diffuse cluster of a typical drone congregation area into a visible clump. [8] In addition to drone attraction to queens, drones are attracted to other drones [14] and virgin queens are attracted to drones. [15]
A honey bee is a eusocial flying insect within the genus Apis of the bee clade, all native to mainland Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America, North America, and Australia.
A queen bee is typically an adult, mated female (gyne) that lives in a colony or hive of honey bees. With fully developed reproductive organs, the queen is usually the mother of most, if not all, of the bees in the beehive. Queens are developed from larvae selected by worker bees and specially fed in order to become sexually mature. There is normally only one adult, mated queen in a hive, in which case the bees will usually follow and fiercely protect her.
The European dark bee is a subspecies of the western honey bee, evolving in central Asia, with a proposed origin of the Tien Shan Mountains and later migrating into eastern and then northern Europe after the last ice age from 9,000BC onwards. Its original range included the southern Urals in Russia and stretched through northern Europe and down to the Pyrenees. They are one of the two members of the 'M' lineage of Apis mellifera, the other being in western China. Traditionally they were called the Black German Bee, although they are now considered endangered in Germany. However today they are more likely to be called after the geographic / political region in which they live such as the British Black Bee, the Native Irish Honey Bee, the Cornish Black Bee and the Nordic Brown Bee, even though they are all the same subspecies, with the word “native” often inserted by local beekeepers, even in places where the bee is an introduced foreign species. It was domesticated in Europe and hives were brought to North America in the colonial era in 1622 where they were referred to as the English Fly by the Native Americans.
Varroa jacobsoni is a species of mite that parasitises Apis cerana. The more damaging Varroa destructor was previously included under the name V. jacobsoni, but the two species can be separated on the basis of the DNA sequence of the cytochrome oxidase I gene in the mitochondrial DNA.
The dwarf honey bee, Apis florea, is one of two species of small, wild honey bees of southern and southeastern Asia. It has a much wider distribution than its sister species, Apis andreniformis. First identified in the late 18th century, Apis florea is unique for its morphology, foraging behavior and defensive mechanisms like making a piping noise. Apis florea have open nests and small colonies, which makes them more susceptible to predation than cavity nesters with large numbers of defensive workers. These honey bees are important pollinators and therefore commodified in countries like Cambodia.
The Cape honey bee or Cape bee is a southern South African subspecies of the western honey bee. They play a major role in South African agriculture and the economy of the Western Cape by pollinating crops and producing honey in the Western Cape region of South Africa. The species is endemic to the Western Cape region of South Africa on the coastal side of the Cape Fold mountain range.
Apis andreniformis, or the black dwarf honey bee, is a relatively rare species of honey bee whose native habitat is the tropical and subtropical regions of Southeast Asia.
Apis koschevnikovi, Koschevnikov's honey bee, is a species of honey bee which inhabits Malaysian and Indonesian Borneo, where it lives sympatrically with other honey bee species such as Apis cerana.
Apis nigrocincta is a species of honey bee that inhabits the Philippine island of Mindanao as well as the Indonesian islands of Sangihe and Sulawesi. The species is known to have queens with the highest mating frequencies of any species of the tribe Apini.
Apis dorsata, the rock bee or giant honey bee, is a honey bee of South and Southeast Asia. They are typically around 17–20 mm (0.7–0.8 in) long and nests are mainly built in exposed places far off the ground, like on tree limbs, under cliff overhangs, and under buildings. These social bees are known for their aggressive defense strategies and vicious behavior when disturbed. Though not domesticated, indigenous peoples have traditionally used this species as a source of honey and beeswax, a practice known as honey hunting.
The Maltese honey bee, Apis mellifera ruttneri, is a subspecies of the western honey bee, endemic to the Maltese islands which are situated in the Mediterranean Sea.
The East African lowland honey bee is a subspecies of the western honey bee. It is native to central, southern and eastern Africa, though at the southern extreme it is replaced by the Cape honey bee. This subspecies has been determined to constitute one part of the ancestry of the Africanized bees spreading through North and South America.
The Macedonian bee is a subspecies of the Western honey bee. It is found mainly in Bulgaria, North Macedonia, Northern Greece and other places in the Balkans as well. Originally this subspecies was described based on morphological characteristics by Friedrich Ruttner, as were the adami, cecropia and cypria subspecies.
The western honey bee or European honey bee is the most common of the 7–12 species of honey bees worldwide. The genus name Apis is Latin for "bee", and mellifera is the Latin for "honey-bearing" or "honey carrying", referring to the species' production of honey.
Apis cerana, the eastern honey bee, Asiatic honey bee or Asian honey bee, is a species of honey bee native to South, Southeast and East Asia. This species is the sister species of Apis koschevnikovi and both are in the same subgenus as the western (European) honey bee, Apis mellifera. A. cerana is known to live sympatrically along with Apis koschevnikovi within the same geographic location. Apis cerana colonies are known for building nests consisting of multiple combs in cavities containing a small entrance, presumably for defense against invasion by individuals of another nest. The diet of this honey bee species consists mostly of pollen and nectar, or honey. Moreover, Apis cerana is known for its highly social behavior, reflective of its classification as a type of honey bee.
Varroa sensitive hygiene (VSH) is a behavioral trait of honey bees (Apis mellifera) in which bees detect and remove bee pupae that are infested by the parasitic mite Varroa destructor. V. destructor is considered to be the most dangerous pest problem for honey bees worldwide. VSH activity results in significant resistance to the mites.
Apis mellifera cypria(Cyprus honey bee) is a subspecies of the Western honey bee. Its habitat is the Mediterranean island of Cyprus.
Apicystis bombi is a species of parasitic alveolates in the phylum Apicomplexa. It infects bees, especially bumblebees. It is believed to have a cosmopolitan distribution in bumblebees and a sporadic occurrence in honey bees, and causes disease symptoms in nonresistant bee species.
