Ground-breaking discoveries by Michigan State University researchers could help protect honeybees from deadly parasites that have devastated commercial colonies.
The MSU researchers for the first time were able to produce in the laboratory proteins that help channel sodium ions through cell membranes of parasites known as Varroa mites. The research, using cellular frog eggs, also found that these proteins react to chemicals differently than the sodium channel proteins in honeybees, a finding that could be a key to controlling the mites.
“The insecticide used to control Varroa mites, fluvalinate, targets the mite sodium channel,” said Ke Dong,MSU professor of entomology. “But the mites are becoming resistant to fluvalinate. Successfully producing the mite sodium channel in the lab now allows scientists to develop new chemicals that target the mite sodium channel but don’t affect the honeybee’s.”
