How fuelish is the honey bee?
Is it as fuel-efficient as say, the new Volkswagen that gets an estimated 170 miles per gallon, more MPG than any other vehicle?
National Public Radio recently posted an interesting article on its Web site comparing the VW with the HB (the honey bee, Apis mellifera).
It seems that when the German engineers rolled out their new VW--an 837-pound car with a 2.6-gallon diesel fuel tank--they boasted it could go 416 miles without stopping for gas.
Nice going, but wait just a minute!
"We suggest," wrote NPR author Robert Krulwich, "that Germany's proud engineers take picnic baskets to the nearest springtime hill and meet their energy-efficient masters, honey bees."
Krulwich recalled that in 1957, Canadian scientist Brian Hocking figured out "bee miles to the gallon."
"Experimenters take a bee, give it all the honey it can eat, and then tether it to a pole," Krulwich wrote, adding that this procedure "neither harms nor seems to disturb the bee."
So, our busy little bee flies around the pole until it runs out of fuel. "The pole measures the distance flown by the rotating bee," Krulwich explained. "Because the experimenter now knows how far a bee can travel on a bee-belly of fuel, you scale up to imagine how far it would go if it had a gallon-sized belly. That's how you calculate Bee Miles Per Gallon."
Hocking's formula: flight efficiency of a bee=0.5 mg per 1 kilometer.
The bee. By far.
The bee gets nearly 5 million miles per gallon, or specifically 4,704,280 MPG.
And that's without packing pollen.
Honey Bee in Flight
Target: Almond Blossoms
Eric Mussen is used to fielding questions about honey bees--how and why they gather nectar, honey, propolis and water; how many eggs a queen bee can lay in a day; and why beekeeper use smokers.
Typical of the questions and his answers:Why do beekeepers use smokers?
The smoke from the smoker has three effects on the bees. First, it prevents the guard bees from liberating much “alarm pheromone” (smells like bananas) in the hive. Second, it prevents “soldier” bees in the hive from smelling the pheromone that has been secreted. Third, it causes many bees to fill up on honey. Despite the wives’ tales to the contrary, there is no reason to believe that the bees “think” there is a fire or that bees full of honey cannot sting.
Can honey bees see color?
Yes, honey bees can see nearly all the colors we see. They cannot see red, which looks black to them. They can see into the UV wavelengths a ways, which is beyond our limit at purple. UV looks black to us.
However, when Mussen takes the stage on Monday, March 1 at the California Small Farm Conference in San Diego, he won't be giving a presentation on honey bees or answering questions.
He'll be receiving a well-deserved award: the Pedro Ilic Outstanding Ag Educator Award for his work in educating the agricultural community, the beekeeping industry and the general public about honey bees.
Mussen, an Extension apiculturist and member of the UC Davis Department of Entomology faculty since 1976, is considered by his peers as one of the most respected and influential professional apiculturists in the nation.
He serves in leadership roles in numerous honey bee organizations, from the California State Beekeepers' Association to the American Honey Producers' Association. He helped found the Western Apicultural Society and served terms as president. The list of service to agriculture and apiculture is both impressive and extensive.
“Yet he is just as open to answering a question about Nosema to a beginning beekeeper or responding to a child’s question about queen bees as he is to helping a commercial beekeeper with 15,000 hives, or engaging in intricate scientific research,” said nominator Larry Godfrey, Extension entomologist with the UC Davis Department of Entomology.
Mussen delivers his messages via computer, phone, field and office visits, research, conferences and publications. Since 1976, he has written the bimonthly newsletter, from the UC Apiaries, and fact sheets called Bee Briefs.
Yet unbeknowst to many of today's agriculturists: Eric Mussen and Pedro Ilic, a small farm-advisor in Fresno County who died in 1994, knew each other. In fact, they worked together as members of the Small Farm Work Group, part of the UC Agriculture and Natural Resources (UC ANR).
"They were alike in many ways: their dedication, enthusiasm, high energy, friendliness, their commitment to small-scale and family farming, and the easy-going way they imparted information on a diversity of projects, solving a multitude of problems—and sometimes at a moment’s notice,” Godfrey said.
Ilic was known as an effective teacher who instilled self-esteem in others and constantly encouraged others, his colleagues said. Illic showed characteristic determination, exuberance, high energy, and genuine friendliness for all people, with the conviction that the smallest is as important as the biggest.
That would be describing Eric Mussen to a "T."
Or to a "B."

It's not too early to start thinking about NPW.
NPW? National Pollinator Week.
They are a key to our global sustainability and food supply. Eighty-percent of the world's crops depend on pollination. Honey bees pollinate about one-third of the food we eat.
Worldwide, we have about 20,000 species of bees, according to native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis. And California alone, he says, has more than 1600 species. Bees include sweat bees, digger bees, leafcutting bees, bumble bees, and scores of others.
Want to know what to plant in your garden to attract bees and other pollinators? Good sites to read are UC Berkeley's Urban Bee Gardens Web site and the Xerces Society Web site.
Meanwhile, almond blossoms are in full bloom in California. At the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis, an almond tree near the apiary is a burst of blossoms and a flash of aromatic fury.
Walk by the tree and you'll see pollen-packing honey bees buzzing around like there's no tomorrow.
We must ensure there will be a tomorrow.

Buds 'n Blossoms
It's Presidents' Day today, a holiday for most of us but not for the honey bees.
The bees are buzzing in and around the almond blossoms, collecting nectar and pollen for their hives. Nectar provides the carbohydrates for the hive, and pollen provides the proteins.
Someone told me yesterday that she thought that the drones (males) gather the nectar and pollen. Not so. (Shades of the inaccurate information released in Jerry Seinfeld's "The Bee Movie" and the equally inaccurate term, "pollen jocks.") No, the only function of the drones is reproduction. When the virgin queen bee heads out on her maiden flight, she'll mate with 12 to 25 drones or so in the drone congregation area. Then the drones die. Happy, probably. If they don't mate, they'll die within a month. Sad, probably.
The queen bee, in peak season, will lay about 2000 eggs a day. The worker bees--all sterile female workers--serve as the nurse maids, nannies, royal attendants, builders, architects, foragers, dancers, honey tenders, pollen packers, propolis or "glue" specialists, air conditioning and heating technicians, guards, and undertakers.
It's a matriarchal society.
So when you see the bees buzzing around the almond blossoms, they're girls. Busy girls. Golden girls. They not only buzz, they rock.
They're the ones that pollinate one-third of the food we eat, including California's 700,000 acres of almonds.
You go, girls!
Wild Blue Yonder
The Tidy Tips, a native California wildflower (Layia platyglossa, family Asteraceae) is a welcome addition to flower beds.
If you walk behind the Sciences Laboratory Building on the University of California, Davis, campus, patches of Tidy Tips abound.
If it's cold, windy and rainy, no honey bees. If we're graced with a "sun break," here come the bees.
Sun break on the Tidy Tips...a sure sign of spring.
