Bee Colony Collapse and Fungus

6 comments
The New York Times published a fascinating article this week linking damp environments to the dramatic reduction in bee colonies in the last 4 years. The article also points out the "crazy" behavior of the bees shortly before they die.

Since 2006, 20 to 40 percent of the bee colonies in the United States alone have suffered "colony collapse."

The culprit?

A fungus interacting with a virus. According to a paper published by Army scientists in Maryland and bee experts in Montana, there are clues as to how the two pathogens work together to kill bees.

"Both the virus and the fungus proliferate in cool, damp weather, and both do their dirty work in the bee gut, suggesting that insect nutrition is somehow compromised."

This is particularly interesting in light of the fact that toxic mold individuals commonly experience digestive problems.

Fungus and viruses often work together in nature, according to the report, and "one answer in protecting bee colonies might be to focus on the fungus — controllable with antifungal agents — especially when the virus is detected."

The researchers, including science team leader Dr. Jerry Bromenshenk, remain baffled by the bees' unusual behavior.

"Still unsolved is what makes the bees fly off into the wild yonder at the point of death. One theory, Dr. Bromenshenk said, is that the viral-fungal combination disrupts memory or navigating skills and the bees simply get lost. Another possibility, he said, is a kind of insect insanity."

When I think back to the height of our toxic mold exposure, I can relate to these bees.

I draw my own conclusion when I read this study. If bees can't survive on a chemical-ridden diet in an environment filled with pathogens... what makes us think we can?

  1. That is interesting you post that. When I first went to a gastroenterologist for digestive issues (before we knew about the mold) he couldn't find anything wrong in the tests. But, the one thing he did say is that sometimes you can get a virus and not notice the stomach effects until later. Now I wonder if he was right...the virus mixed with the fungus. Hmmm.

  2. You can make it!

  3. "Memory and navigating skills", yep... been there and still there...who knew we had something in common with bees. And the combo hit of a virus + fungus is very interesting! Thanks for the post Andrea. kt

  4. A follow-up article appeared October 8 in Fortune Magazine discussing a possible conflict of interest regarding the impact of pesticides on the bee colonies. Click here to view the article.
