Faster than a speeding bullet...
As soon as UC Davis bee breeder-geneticist Susan Cobey opened a beehive and removed a chunk of honeycomb to show visitors, here came the speeding bullet. A fast camera shutter caught what the eye couldn't see.
It was a queen yellowjacket taking dead aim at the comb.
"The yellowjacket queen this time of year zeroes in on the honey as soon as you open a hive," said Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility.
"They build up their populations in the fall and eat the bees for protein to overwinter. They can actually kill bee colonies, especially weak ones. As meat-eating predators, these are common at picnic time, for which honey bees are often unfairly blamed."
Yes, honey bees are indeed unfairly blamed. Like human vegetarians, honey bees don't eat meat. They may land on your soda can for the sugar water, but meat doesn't interest them. They forage for nectar and pollen.
Now yellowjackets--they're predators. They love meats and sweets. You'll see these uninvited guests at your picnic or barbecue, boldly sampling your steak, hamburger or chicken; targeting your can of soda; or scavenging in and around your garbage can.
They also vigorously defend their nests, which look like paper combs. Do not go near their nests.
Their sting is painful. A yellowjacket recently nailed UC Cooperative Extension Apiculturist Eric Mussen beneath the collar as he was checking the honey bees at the Laidlaw facility.
Mussen noted that beekeepers inadvertently kill a few bees each time they open a hive and pry open the "stuck-together" frames with their hive tool. The dead bees fall to the ground--to the waiting yellowjackets. The yellowjackets then carry the bees off to their nest, chew them into pulp, and feed the "protein" to their brood.
More yellowjackets on the way.
And soon, more speeding bullets.
Sheridan Miller's gift to UC Davis for honey bee research was both generous and thoughtful.
The 11-year-old Bay Area resident raised $733 for the Harry H. Laidlaw Jr. Honey Bee Research Facility through the sale of jars of honey, candles, baked goods and a self-penned booklet on the plight of honey bees.
The fifth grader and her family (father Craig, mother Annika and sister Annelie, 8) traveled from their home in Marin County to present the check to Lynn Kimsey, professor and chair of the Department of Entomology and director of the Bohart Museum of Entomology. Bee breeder-geneticist Susan Cobey guided the group on a tour of the Laidlaw facility and apiary.
“It’s very thoughtful and generous of a little girl to think of the plight of the honey bees and to raise funds for research,” Kimsey said. "We are overwhelmed.”
Said Cooperative Extension Apiculturist Eric Mussen, a member of the UC Davis Department of Entomology since 1976: “I really appreciate the fact that so many members of the general public have become concerned about the plight of honey bees. I am particularly impressed by individuals such as Sheridan who have devoted so much time and effort in really trying to improve the health and longevity of the honey bees.”
"Honey bees pollinate delicious fruits, vegetables and even nuts," Sheridan wrote. "If they were to disappear, our food source would consist of wheat, rice and corn."
Sheridan's dedication deeply illustrates what one person can do to help save the bees.
Sheridan cannot imagine a world without bees. Neither can we.
What's happening with the honey bees?
Those following the mysterious phenomonen known as colony collapse disorder (CCD)--characterized by bees abandoning their hives--are eagerly waiting the latest developments.
So, when UC Davis bee breeder-genetist Susan Cobey recently offered a class on queen-bee rearing at the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis, she invited Cooperative Extension Apiculturist Eric Mussen to address the group.
Mussen, who is entering his 33rd year as a member of the UC Davis Department of Entomology, is considered one of the top authorities on honey bees in the country, and indeed the world. News media--including the Associated Press, New York Times, Boston Globe, BBC, Los Angeles Times and Good Morning, America--seek his expertise.
Lately he's been asked if the newly published research work in Spain "solves" the global mystery of CCD. It does not.
"It is true that we have available to us an antibiotic that, when used properly, practically eliminates the disease-causing fungus, Nosema ceranae, from our colony populations," he wrote today in answer to an inquiry. "However, in many cases, nosema-free colonies continued to dwindle to nothing very quickly in many parts of the country. Whatever the causes of that collapse may be, elimination of nosemosis, alone, is not adequate to improve the health of our colonies enough that they survive."
"We need to increaes our research efforts on this malady," Mussen said, "so that we can assure the existence of healthy honey bee colonies for the production of the fruits, vegetable and nuts that make up the healthiest one third of our daily diets."
Freerk Molleman, a postdoctoral scholar in professor James Carey's lab at UC Davis, kindly video-taped Mussen's hour-long lecture to Cobey's class.
Here it is: what's happening with the bees.
Except it wasn’t planned.
On the last day of a two-day advanced workshop on "The Technique of Instrumental Insemination,” taught by bee breeder-geneticist Susan Cobey at the Harry H. Laidlaw Jr. Honey Bee Research Facility. UC Davis, bees from one of the hives began to swarm.
It was perfect for one of Cobey's students, Ventura resident Bill Weinerth,
The bees headed for a nearby tree. Cobey, manager of the Laidlaw facility, smoked them to calm them down before shaking the bees loose and into their new home: an awaiting hive.
Weinerth loves working with bees. “I’ve had bees all my life except for 10 years when I was going to school (master’s of divinity),” he said.
“When I was 12, and living in
It's been a bee-loved passion every since.

With the opening of baseball season, it's "peanuts, popcorn and Cracker Jacks!"
But to beekeepers, it's peanuts.
Or rather, peanut-like shells.
Immature queen bees grow to maturity in cells that resemble peanut shells.
When UC Davis bee breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis, led a recent queen-bee rearing class on a tour of commercial queen bee producers, one of the stops was at C. F. Koehnen & Sons, Inc., Glenn, Calif.
The Koehnens, in the bee business since 1907, are the largest producers of honey bees and queen bees in California. They maintain more than 15,000 colonies. The Cobey class marveled at the operation.
A beekeeper held a frame up to the sky as worker bees cleaned out the vacated queen bee cells.
Not your basic goober peas!
