The Africanized Honey Bee is a result of mating between African bees and European honey bees of North and South America. In 1956, a geneticist brought African queens to Brazil with the idea of developing a superior honey bee, one more suited to tropical conditions. Unfortunately, some of these bees were accidentally released near Sao Paulo, Brazil. The bees interbred in the wild with the European honey bees, resulting in "Africanized" offspring. They have spread throughout most of South America, Mexico, southern parts of Texas, New Mexico, Arizona, and California.
