"More than three years after beekeepers starting seeing the sudden disappearance of hive populations, scientists have yet to find the cause -- let alone the fix -- for a condition called colony collapse disorder (CCD). Meanwhile, the commercial beekeeping industry is struggling to provide pollination services to the nations' farmers. One-third of food crops rely on insect pollination.
A recently published survey suggests that hive losses have stabilized at around 30 percent a year, but that high figure is based on last winter's data. Anecdotally, the losses have climbed this winter, although a formal tally won't occur until the spring."
