Honey bees are among the world's most important insects. They help pollinate many of the crops we depend on for food. Without them, the global food supply would be in great danger.

In 1998, beekeepers in Europe made a shocking discovery--almost all of the honey bees had disappeared from their hives. Several years later, beekeepers in the United States found that many of their honey bees had vanished too. Scientists called this disappearance colony collapse disorder (CCD), and at first, no one knew why it was happening.

It was time to call the bee doctors! Join author Sandra Markle as she explores what apiologists--scientists who study bees--have learned about CCD and what they are doing to prevent it from spreading further.
