"Killer bees," more formally called Africanized bees, originated in 1957 in southeast Brazil when 26 Tanzanian Queen bees were released to the wild by a replacement beekeeper and mated with local drones of European bee species. The Queens had been brought to Brazil for use in hybridization experiments.
