1)An american hybrid of the African and European honeybees produced by the mingling of domesticated European colonies with an expanding and migrating African colony in Brazil in 1956. 2)A honey bee , native to africa, that is extremely aggressive and attacks in swarms when disturbed.
Africanized honey bees, known colloquially as "killer bees", are some hybrid varieties 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. iberiensis. The hybrid bees are far more aggressive than any of the various European subspecies. Small swarms of Africanized bees are capable of taking over European honey bee hives by invading the hive and establishing their own queen after killing the European queen.Their sting is no more deadly than that of normal bees, but Africanized bees tend to be less docile than normal so are more ready to sting. When one bee stings, it also releases an attack pheromone which attracts other bees who are also more likely to sting. If people are badly affected it will be because of the sheer number of stings they receive.they live in parts of America and Africa. (most commonly found in Texas)

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. They are robust, 3/4 of an inch in length, and are covered in fuzz. They are brownish in color with black stripes that aren't as distinct as those on wasps or hornets. They have four clear wings that are attached to the thorax, which is the middle section of the body. The six legs are also attached to the bottom of the thorax. The abdomen is larger than the thorax and ends in the stinger, and the head is smaller than both of the sections. The two compound eyes are large and bulbous and allow the Africanized Honey Bee to see ultraviolet rays, enabling them to fly at night. The queens are the largest bees in the social structure, followed by the drones and then the workers.
Africanized Honey Bees and European Honey Bees may be similar in appearance, but not in behavior. Africanized Honey Bees will attack when unprovoked, and they respond rapidly and in large numbers to disturbances that European Honey Bees would ignore. Like European Honey Bees, Africanized Honey Bees can sting only once; they deliver a venom identical to that of European Honey Bees. Both types of bee die shortly after leaving their stings and ends of their abdomen in their victim.
1)they are called Africanized Honey Bee. 2)they are called killer bee because Africanized bees will actually pursue intruders and continue to sting him even after he has died, and they may interpret an intruder as no more than a passerby. 3)?????(i dont know) 4)they live in africa

Killer bees, or Africanized honey bees, are hybrid mistakes. They first came to being in 1957, when a replacement bee keeper accidentally released 26 Tanzanian queen bees in between the rest of the bee hives, on a farm in South Eastern Brazil. The hives had belonged to biologist, Warwick E. Kerr, who had intended to interbreed European bees with Southern African bees, to create a strain of bees that would produce more honey and that would adapt better in tropical conditions than European bees. Since their release, the killer bees have multiplied and migrated. They can be found throughout South America and through most of North America, now. Africanized honey bees are highly aggressive, hence the name “killer bee”, and are known to move huge distances in massive swarms. When they are threatened in any way, they will attack, and their attacks came in large numbers. They will ruthlessly sting any threat to death, as happens to about two people a year in the US.
During a 1957 science experiment ,African killer bees were accidentally released in Brazil.
