The africanized bee, also known as the africanised honey bee, and known colloquially as killer bee, is a hybrid of the western honey bee species (apis mellifera), produced originally by cross-breeding of the african honey bee (a m scutellata) with various european honey bees such as the italian bee a m ligustica and the iberian bee a m. Africanized bees or killer bees are descendants of southern african bees imported in 1956 by a prominent brazilian geneticist, warwick kerr, attempting to breed a honey bee better adapted to the south american tropics. Currently, the africanized honeybees can be found in most of the american southwest and all of florida, and are moving north at an average rate of two miles a year scattered reports have occurred as far north as tennessee, probably from imported bees.

Seeking to combine the african honeybee's prolific breeding and warm-weather adaptations with the european honeybee's production of honey, brazilian scientist warwick kerr cross-bred the african bee with an italian variety of the european honeybee in the 1950s. This happened in arizona on the merkle memorial trail in usery mountain park authorities still haven't released the species involved, probably africanized bees, but it's possible it was the less aggressive european honeybees.

Ancestors to most honey bees and are docile for humans to hand country in east africa where killer bees were brought from brazilian entomologist who brought killer bees from africa to. The other view argues that africanized honeybees are better pollinators than european honeybees because they emphasize brood rearing and colony growth instead of honey production the shift in resource management allows africanized honeybees to forage more for pollen than european bees.
Geneticist, dr warwick kerr, as per the request of the brazilian government, was asked to create a bee that would withstand a tropical climate but breed it with the european honey bee during the time warwick was working with numerous species of african honey bees, some of them managed to get loose and began to mate with local drones and queens. Africanized honey bees warwick kerr brazilian entomologist who brought killer bees from africa to south america. Africanized honeybees are a hybrid of the european honeybee and african bees they are more dangerous and defensive than regular honeybeesbecause of this, some people call them 'killer bees.
In 1957, the brazilian scientist, warwick kerr, im- ported african honey bees (ahb) ( apis mellifera scutellata ) to genetically cross with european honey bees with hopes of. The mixing of genes that created africanized honey bees occurred in the 1950s in 1956, dr warwick kerr, a bee researcher in brazil, hoped to develop a bee that would thrive in brazil's tropical climate. The africanized honey bee is far more aggressive than the european honey bee while all hives attack potential hazards around them, the africanized honey bee is known to attack animals without any provocation and with hundreds of bees compared to the handful of bees european honey bees use to ward off intruders. The introduction of africanized honeybees into the western hemisphere was the result of a scientific experiment gone awry, according to a texas a&m university report.
Thus, in 1956, the brazilian scientist warwick kerr suggested to import african honeybees to brazil instead of the european ones in an effort to increase honey production then, the unique main problem he needed to solve was the aggressive nature of this subspecies. Africanized honey bees are said to carry more pollen than european honeybees they can also produce more honey per bee than european honeybees ahb's have a stronger immune system they are less susceptible to mites and other diseases. Africanized bees -- first introduced into the americas in the 1950s as part of an experiment by brazilian geneticist warwick kerr -- are a genetic hybrid of the more docile european honeybees and.
