The first reported cases of colony collapse disorder (CCD) in 2006 were identified by a commercial beekeeper from Pennsylvania, U.S., who was overwintering his colonies in Florida.1

While this report marked the initial recognition of the phenomenon in the fall of 2006, subsequent investigations indicated that beekeepers had likely experienced similar unexplained losses for at least three years prior. By early 2007, the disorder had been reported across several other states, including California, Oklahoma, and Texas, as well as in the mid-Atlantic region and the Pacific Northwest.1
