colony collapse disorder

For almost two years, the honeybees that support almost all human agriculture have fought a plague right out of a sci-fi movie. Varroa mites, a deadly parasite, have hid in the labyrinthine combs of beehives, feeding off the juices of still-living insects, and causing the the problem we know as Colony Collapse Disorder.

To help our bee allies fend off the alien invaders, the Agriculture Research Service division of the Department of Agriculture has created a new breed of super-vigilant bees that will take the fight to the mites.

Since 2006, about 30 percent of the commercial honeybee population has died off due to Colony Collapse Disorder. Though many theories have emerged about the causes of CCD since it first began ravaging honeybee populations, a study released this week has identified the first molecular marker of the disorder.

People generally know that substances that are harmless when taken separately in small doses can lead to disorientation, and perhaps uncharacteristic behavior, when mixed. Honey bees, apparently, do not. After all, dabbling is what honey bees do, and it's what we love them for. These little workers are responsible for billions of annual agricultural industry dollars, thanks to their pollination services. But bees haven't been staying on task. They've been acting a little weird lately--leaving their hives and not coming back--and attracting a lot of attention for it.

More discouraging statistics this week from the Apiary Inspectors of America: 36.1 percent of commercially managed beehives in the U.S. have been lost in the past year. While the group only began to track these numbers last year when Colony Collapse Disorder (CCD) was first appearing, the two years of losses add up to a bleak picture for honeybees. These drops are undoubtedly unsustainable over the long term and the situation is not improving.

Weve by now all seen the news that bees are dying in huge numbers. Scientists have labeled the phenomenon Colony Collapse Disorder, or CCD. Dead bees mean less crop pollination, which means less food at higher prices. Whats causing the problem is still anyones guess. Now, strangely, bats in the eastern U.S. are experiencing a similar plague which biologists have dubbed White Nose Syndrome (WNS) for the white fungus that appears on their bodies at the height of infection.

In a typical lab culture, a microbial organism is first isolated and grown in a sterile environment. Generally, the starting point is just a single cell or organism. The resulting growth is then called a clonal culture because every cell produced is genetically identical. This technique gives researchers the ability to study exactly what they want from the cell, without any environmental interference.

Scientists still are unsure what caused the massive decline in bee populations last year. It could be part of a natural cycle or the result of something more insidious—but one thing is clear, both food producers and consumers will suffer if the drop continues.
