The Africanized bee, also known as the Africanized honey bee (AHB) and colloquially as the "killer bee", is a hybrid of the western honey bee (Apis mellifera), produced originally by crossbreeding of the East African lowland honey bee (A. m. scutellata) with various European honey bee subspecies such as the Italian honey bee (A. m. ligustica) and the Iberian honey bee (A. m. iberiensis).
The East African lowland queens' virgin daughters mated with local European honey bee drones and produced what is now known as the Africanized honey bee in South and North America. The intense struggle for survival of western honey bees in Sub-Saharan Africa is given as the reason that this subspecies is proactive in defending the hive and also ...
Another important factor was thought to be differences between the species in age polyethism, or the allotment of different tasks as a honey bee ages. [12] Young worker bees focus on in-hive assistance such as brood care, and the relatively younger African bee populations were thought to be one explanation for the emphasis on reproduction and ...
The term hive is used to describe an artificial/man-made structure to house a honey bee nest. Several species of Apis live in colonies. But for honey production, the western honey bee (Apis mellifera) and the eastern honey bee (Apis cerana) are the main species kept in hives. [1] [2]
Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best known honey bee is the western honey bee, (Apis mellifera), which was domesticated for honey production and crop pollination. The only other domesticated bee is the eastern honey bee (Apis cerana), which occurs in South, Southeast, and East Asia.
The propensity to swarm differs among the honey bee species. Africanized bees are notable for their propensity to swarm or abscond. Absconding is a process where the whole hive leaves rather than splits like in swarming. This process is mainly determined by climate and effects of climate change and nectar flow.
While some colonies live in hives provided by humans, so-called "wild" colonies (although all honey bees remain wild, even when cultivated and managed by humans) typically prefer a nest site that is clean, dry, protected from the weather, about 20 litres (4.4 imp gal; 5.3 US gal) in volume with a 4–6 cm 2 (0.62–0.93 sq in) entrance about 3 ...
Apis mellifera monticola is known by the common name of the East African mountain honey bee. In 2017 its complete mitochondrial genome was sequenced, confirming that it belonged to the A Lineage of honey bees and concluding that "A phylogenetic tree showed that A. m. monticola clusters with other African subspecies".
