ZomBee Watch tracks bee-killing parasite
HURLEY, N.Y.— Call them “the Buzzing Dead.”
Honeybees are being threatened by tiny flies that lead them to lurch and stagger around like zombies. The afflicted bees often make uncharacteristic night flights, sometimes buzzing around porch lights before dying. Well-documented on the West Coast, some zombie-bee cases also have been detected in eastern states by volunteers helping track its spread. This comes as honeybees have already been ravaged in recent years by mysterious colony collapse disorder, vampire mites and nutritional deficiencies.
“We’re not making a case that this is the doomsday bug for bees,” said John Hafernik, a biology professor at San Francisco State University. “But it is certainly an interesting situation where we have a parasite that seems to affect the behaviour of bees and has them essentially abandoning their hive.”
In 2012, Hafernik started a project to enlist people to track the spread of zombie bees called ZomBee Watch. Participants are asked to upload photos of the bees they collect and photos of pupae and adult flies as they emerge. They have more than 100 confirmed cases.
The fly had already been known to afflict bumblebees and yellow jackets. Then in 2008, Hafernik made a discovery after scooping up some disoriented bees beneath a light out- side his campus office. Before long, he noticed pupae emerging from a bee.
That led to the first of many zombie honeybee cases found in the San Francisco area and beyond. Researchers believe Apocephalus borealis flies attack bees as they forage. The flies pierce the bees’ abdomens and deposit eggs, affecting the behaviour of the doomed bees.
A beekeeper in Burlington, Vt., detected the first zombie case in the East, in 2013. Then this summer, amateur beekeeper Joe Naughton of Hurley, N.Y., discovered the first of two recently confirmed cases in the Hudson Valley, north of New York City.
Naughton, who has 200,000 or more bees, is not panicking just yet.
“You know, the ‘zombie’ thing is a little bit sensational and some people hear that and they go right into alarm bells ringing,” Naughton said. “Where the state of things are right now is mostly just fact finding.”
