Backyard beekeeping is a dying art in the American Southwest, in large part because of the invasion of Africanized bees. They’re more defensive than European honey bees, and that takes the charm out of the hobby. But they also have more resilient genes. So despite their nasty reputation, some beekeepers want to work with Africanized bees. That’s easier to do in northern Arizona, where cooler temperatures mean calmer bees.
