If you have a bee hive, you most likely have mites.
Varroa mites, those blood-sucking parasites that latch onto the brood and also thrive on the adult bees, can weaken and destroy a hive.
Extension apiculturist Eric Mussen, member of the UC Davis Department of Entomology faculty, frequently fields calls about varroa mites.
In his latest edition of from the UC apiaries, he points out that "obtaining fumigants for varroa mite control may be somewhat difficult at this time for beekeepers."
"I haven't checked on the Apiguard® situation recently, but shipments from Europe had been held up, apparently by U.S. customs," Mussen wrote. "The other desired fumigant, Mite Away II pads, are vanishing from the market quickly. They are out of production and soon will not be available. The reason behind this is because NOD Apiary Products, in Canada, has decided to stop producing the pads and instead offer a formic acid product in strip form."
Today we spotted a varroa mite on a foraging bee. The bee, a golden Italian, was nectaring lavender.
Unfortunately, a nasty little parasite was eating at her.
When the Antioch Charter Academy, a middle school in Contra Costa County, toured the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis on Tuesday, May 4, they learned all about honey bees and native bees.
Tour coordinator Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology set up three activity stations, visited by groups of 13.
Extension apiculturist Eric Mussen, member of the UC Davis Department of Entomology faculty, talked to them about bee biology, bee communication and colony collapse disorder; Yang and native pollinator specialist Robbin Thorp, emeritus professor of entomology, discussed bee diversity, bee monitoring, bee identification and foraging behavior; and to top it off, bee breeder-geneticist Susan Cobey and Elizabeth Frost displayed bee equipment, discussed the breeding program and then opened several hives.
The students singled out the three castes: queen bee, drones and worker bees. They admired the many different colors of pollen. They gingerly picked up drones (male bees have no stingers).
Then at the urging of Cobey and Frost, the teenagers dipped their fingers into the honey.
Straight from the hive.
Their verdict: "Wow, this is good!"
A taste of honey, a picture of contentment, and a greater admiration for the work of honey bees.
Many Colors of Pollen
A Taste of Honey
If you cotton to honey, you'll want to head over to Briggs Hall tomorrow (Saturday, April 17) during the 96th annual UC Davis Picnic Day.
You can sample cotton honey, as well as five other flavors, from 11 a.m. to 4 p.m.
Extension apiculturist Eric Mussen of the UC Davis Department of Entomology faculty will be offering samples of these honeys: orange blossom, eucalyptus, raspberry, meadowfoam (a vernal-pool flower that is grown commercially in Oregon for oil), starthistle, and cotton.
You'll get six toothpicks, one for each container of honey. You'll taste the exquisite meadowfoam, the exotic raspberry, and then what some folks say is the "best-of-the-best" honey--starthistle. Bees make this from an invasive, exotic weed that agriculturists hate. Our tiny winged agricultural workers love it.
And then you'll taste cotton. Hint: it's a light-colored variety of honey.
If you have a question about honey bees, including colony collapse disorder, ask away.
At Mussen's booth, you can also taste "Honey Lovers," the fruit chews that Gimbal's Fine Candies makes with real honey. Gimbal's, located in San Francisco, is donating 5 percent of the proceeds from the sale of Honey Lovers to UC Davis honey bee research.
These sweet treats at Briggs Hall are free.
Here's what else the entomologists are planning at Briggs Hall and at the Bohart Museum of Entomology.
You'll see racing cockroaches, termite trails, Maggot Art, kissing bugs, fleas, ticks, walnut twig beetles and the like, and you can take home some free ladybugs (lady beetles) from the statewide UC Integrated Pest Management Program.
But it's the honey that makes UC Davis Picnic Day so sweet.
Honey Bee on Lavender
When some folks think of a honey bee, they immediately think of stings.
Not pollination, not honey, not colony collapse disorder, but stings.
To beekeepers, stings are a minor irritation, or perhaps not an irritation at all. It's just something that happens in an occupation. "It's like grease on a mechanic's hands," says bee breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Facility at the University of California, Davis.
Or, I imagine, like flour on a baker, dirt on a gardener or sweat on an athlete.
Yesterday, when Extension Apiculturist Eric Mussen of the UC Davis Department of Entomology faculty was opening a hive at the UC Davis apiary, a bee landed on his wrist.
"Bee on my wrist," he said, knowing I had my macro lens at the ready.
The bee, defending her hive, did what a good guard does--she stung him. When that happens, you scrape the stinger off with your fingernail so the barbed stinger with its attached venom sac doesn't continue to pump venom.
When a worker bee stings and pulls away from her victim, part of her anatomy pulls away, too. She dies, often within minutes.
What you usually see is only the stinger. Not this time. The camera lens caught the barbed stinger and the stretched tissue.
That one word aptly describes the generous donation by Gimbal's Fine Candies, San Francisco, to aid honey bee research at the Harry H. Laidlaw Jr. Honey Bee Research Facility at the University of California, Davis.
Extension apiculturist Eric Mussen, member of the UC Davis Department of Entomology faculty, recently accepted a check for $10,000 from Lance Gimbal, CEO of Gimbal's.
Seeking to help save the bees, company officials expressed concern about the declining bee population. USDA just reported a 29 percent drop in bee population in 2009. “Approximately one-third of our food supply depends on honey bees,” Lance Gimbal said.
The fact is, honey bees are in trouble and we must all do our part to help save the bees. For example, we can plant bee friendly gardens, avoid using pesticides in our garden, take up backyard beekeeping, buy only U.S. honey, and generally raise awareness about the plight of the honey bee.
This is the fourth year of colony collapse disorder (CCD), a mysterious malady characterized by adult bees abandoning the hive. They just fly off, leaving behind the queen bee, brood and stored food. This year is the worst ever for CCD, said Lynn Kimsey, director of the Bohart Museum of Entomology and professor and vice chair of the UC Davis Department of Entomology.
Enter Gimbal's Fine Candies. It just launched Honey Lovers, fruit chews made with natural honey, and will give UC Davis 5 percent of the proceeds for honey bee research.
Said Mussen: “The UC Davis bee biology program is extremely appreciative of the generosity of Gimbal’s Fine Candies. Their contribution will enable us to reach more people with factual information about bees and beekeeping. It also is possible that their support of our research efforts may help uncover better methods of dealing with pests, parasites, and diseases of honey bees and honey bee colonies.”
The allergen-free line of candy is available at Walmart and Fresh & Easy stores, as well as Amazon.com and candydirect.com. Additional stores featuring Honey Lovers will launch this spring.More information on bee research at UC Davis is on the bee biology Web site. More information on Gimbal’s Fine Candies is available from (800) 344-6255 or from its Web site.
Meanwhile, the folks at the UC Davis Department of Entomology are grateful that Gimbal's has stepped forward.
If honey is the "soul of a field of flowers," as someone once said, then businesses and individuals concerned about maintaining healthy bees are "surely the heart."
