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 ...

Dec 28, 2024 · An Africanized honeybee is a hybrid honeybee resulting from the accidental release of African honeybees into the Western Hemisphere in 1957 and their subsequent crossbreeding with local western honeybees.

Jul 2, 2022 · The Africanized honey bee is a mix of European honey bee species combined with the African honey bee. Also known as the killer bee, this hybrid race is well-known for its willingness to attack. It is not used by commercial beekeepers and is considered a major threat to apiaries in the United States.

Oct 19, 2020 · Scutellata-European hybrid honey bees (also known as ‘Africanized’ honey bees) have been some of the most ecologically successful; originating in a 1950s experimental breeding program in Brazil, they rapidly came to dominate across most of the Americas.

Oct 28, 2014 · In 1957, researchers in Brazil were conducting an experiment where they cross-bred two subspecies of honey bee — the Africanized honey bee and European honey bee — when several colonies of the hybrid bees escaped from the research station.

The AHB is the hybrid offspring of African honey bees brought to Brazil in 1956 and honey bees commonly found in this hemisphere. Because of the way AHBs have been portrayed in the media, some people believe these bees swoop down from the sky, en …

The Africanized Honey Bee, more popularly known as the "killer" bee, has the general appearance of the more temperamental European Honey Bee (Apis mellifera). However, they are slightly smaller, but only microscopic measurements in a laboratory would be able to distinguish between the two.

Oct 19, 2020 · We use broad geographic sampling and whole genome sequencing of over 300 bees to map the distribution of scutellata ancestry where the northern and southern invasions have presently stalled, forming replicated hybrid zones with European bee populations in California and Argentina.

hybrid bees less competitive and less efficient at foraging, swarming, and mating. As a result, hybrid colonies may not survive well in the wild, which would contribute to the loss of European traits.

Sep 11, 2015 · The resulting hybrid offspring are known as "Africanized" honey bees. Africanized bees have since spread throughout much of the Western hemisphere, and the advance of African genes both north and south from the introduction site has become one of the most-studied cases in the hybridization literature (reviewed in [ 4 , 5 ]).
