2、 beekeepers across the country, 25 to 40 percent of the honeybees in the United States have vanished from their hives since last fall. So far, no one can explain why.   Colony collapse is a serious concern because bees play an important role in the production of about one-third of the foods we eat.

3、 As they feed, honeybees spread pollen from flower to flower. Without this process, a plant can’t produce seeds or fruits.   Now, a group of scientists and beekeepers have teamed up to try to figure out what’s causing the alarming collapse of so many colonies. By sharing their expertise in honeybee

And bees from collapsing colonies don’t look very healthy. “Their stomachs ar

Moreover, they have high levels of bacteria inside their bodies.   Another cause of colony-collapse disorder

If it turns out that a disease is contributing to colony collapse, bees’ genes could explain why some colonies have collapsed and others have not. In any group of bees there are many differ
