African honeybees are more aggressive and when a sentry ruptures its venom sac by stinging, all males in the hive swarm out to assault the victim as opposed to the European pattern of limited response by the nearest warriors.
Also they will pursue for a radius of 400 meters, instead of 100 meters.
In North America,  European bees brought into proximity to African hives, while remaining genetically distinct, began adopting the aggressive social behaviors of African bees.
These "Africanized" bees further spread the social pattern, leading to a wave of "killer bees" north from Mexico, where the pattern originated, into the United States.  It has been halted by the destruction of commercial and hobbyist hives throughout border states, in a "scorched earth" policy to halt "killer bees".
