ESSEX JUNCTION, Vt.— Vermont beekeepers face mite infestations, extreme temperature swings and the possibility of colony collapse. Last fall, a new threat emerged: zombie bees.
Beekeeper Anthony Cantrell of Burlington discovered zombie bees in his hive in October, the first time they’d been found in the eastern United States.
John Hafernik, a professor from San Francisco State University, discovered the first zombie bees in 2008. A fly called Apocephalus borealis attaches itself to the bee and injects its eggs, which grow inside the bee, Hafernik said. Scientists believe it causes neurological damage resulting in erratic, jerky movement and night activity, “like a zombie,” Hafernik said by phone Tuesday.
These aren’t undead bees doomed to roam for eternity. They often die only a few hours after showing symptoms, Hafernik said.
Hafernik and his team of colleagues and students have been tracking the zombie bee spread across the United States. California, Washington, Oregon and South Dakota all have confirmed zombie bees while this is the first time the bee has been found this far east, said Hafernik. The fly previously attached to bumblebees as hosts, not honeybees, according to Hafernik.
“Right now, we don’t know if it’s an isolated thing,” Stephen Parise, Vermont agricultural production specialist, said Tuesday at the state’s annual farm show.
