Would you believe varroa mites, carbon dioxide and indoor wintering are working together to make keeping bees easier and more profitable? Well, believe it.
Today, we talk with Dr. Brandon Hopkins from Washington State University. His research has shown that if colonies are overwintered in an environmental chamber that can control the levels of the gasses the bees are exposed to, that by adjusting the level of carbon dioxide from a normal 0.04% to over 8.5%, mites in those colonies die. Really. And what’s more, the bees don’t, really!
Temperature was set at just about 40 degrees, the chamber was dark, and after 64 days, mite mortality was extremely high. High enough to prove that this could be a mite controlling tool to use in indoor wintering.
To show a difference, another chamber was set up with a 0.12% carbon dioxide concentration, and there was a significant difference in mite mortality was recorded between the two. High carbon dioxide equally high mortality, low concentration equals low mortality.
There is much more research underway. Stay tuned!
