Killer bees started in Brazil in 1957. A scientist in Sao Paulo wanted bees to make more honey （蜂蜜）. So he put forty-six African bees with some Brazilian bees. The bees bred （繁殖）and made a new kind of bees. But the new bees were a mistake. They didn’t want to make more honey. They wanted to attack. Then, by accident, twenty-six African bees escaped and bred with the Brazilian bees outside.
Scientists could not control （控制）the problem. The bees increased fast. They went from Brazil to Venezuela. Then they went to Central America. Now they are in North America. They travel about 390 miles a year. Each group of bees grows four times a year. This means one million new groups every five years.
