Why
do some bees leave the hive and never return?Extension Apiculturist Eric Mussen (right), a member of the UC Davis Department of Entomology faculty, touches on these subjects in the latest edition of from the UC Apiaries, a bimonthly newsletter he's been writing since 1976.
Mussen, who will be the keynote speaker at the 120th annual California State Beekeepers' Association, set Nov. 17-19 in San Diego, keeps beekeepers informed.
His topic at the state beekeepers' meeting? “Glimpses of California’s Beekeeping Future.” He'll speak at 10:30 a.m. on Tuesday, Nov. 17 at the convention headquarters, the Hilton Resort and Spa.
Mussen, who was named the California Beekeeper of the Year in 2006, won the American Association of Professional Apiculturists’ Award of Excellence in Extension Apiculture in 2007. In 2008 he received the Distinguished Achievement Award in Extension from the Pacific Branch of the Entomological Society of America.
A noted authority on honey bees, Mussen has been interviewed by Good Morning, America, the Lehrer Hour, National Public Radio, California Heartland, New York Times and the Los Angeles Times, among other media.
Other UC Davis speakers at the conference will be breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility and assistant professor and native pollinator specialist Neal Williams.
Cobey, who was named the association’s California Young Beekeeper of the Year in 1986, will speak Nov. 17 on “Update on Stock Improvement.” Williams will discuss his work as the UC Davis new native pollinator specialist on Nov. 18.
Meanwhile, hot off the presses, is the September-October edition of from the UC Apiaries. You can read the current edition and back editions, 1994-2009, here. There's no charge to download the newsletters.

Honey Bee and Catmint

A bee is a bee is a bee?
Poet Gertrude Stein ("a rose is a rose is a rose") could have said that.
True, there's only one species of honey bee in the United States--Apis mellifera, the Western or European honey bee--but there are several races.
The "gold standard" is Apis mellifera ligustica, also known as the Italian honey bee, the most common bee in America. It's basically your yellow or golden bee.
But among the other popular races is Apis mellifera carnica, aka the Carniolans or "Carnies," a darker bee. It is primarily darkish gray.
We spotted both of them last weekend sharing a lavender--the blond Italian bee on one side and the darker Carniolan bee on the other.
Author Richard E. Bonney writes in his book, Beekeeping: A Practical Guide: "For the most part, they (the races) are the result of evolution in geographic isolation (Italians on the Italian peninsula, for instance) where the specific climate and vegetation influenced their development over the ages. Each race has specific traits that relate to the geographic origin of that race."
At UC Davis, bee breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility, focuses her research on identifying, selecting and enhancing honey bee stocks that show increasing levels of resistance to pests and diseases. In the early 1980s, Cobey developed her New World Carniolans stock by back-crossing stocks collected from throughout the United States to create a more pure strain.
“Over time, it has proven very productive, winter hardy, well-tempered and more resistant to pests and disease,” says Cobey, who teaches advanced courses on queen bee rearing and queen bee insemination, drawing students from throughout the world.
Genetic diversity, the raw tools for selection, is critical “in maintaining colony fitness and resisting pests and diseases,” she notes.
No matter the races, the honey bees still race for the lavender.
And the other bee friendly plants...

The Italian and the Carniolan
It was an unexpected visit.
UC Davis bee breeder-geneticist Susan Cobey noticed the critter in one of the restrooms at the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis.
She found it several days after the massive Oct. 12 storm raced through Northern California.
The heavy rain soaked the earth, apparently forcing the critter from its habitat.
How it wound up in the restroom is anybody's guess.
What is it?
Jerusalem cricket.
Not a true cricket, though. It's an insect (genus Stenopelmatus) that feeds primarily on decaying organic material (and occasionally insects). It burrows into the soil using its highly specialized feet.
And yes, it does inflect a sometimes painful bite, as Cobey can attest.
It's not lethal though.
Cobey returned it to the Laidlaw grounds, releasing it near a stump.
She has no plans to trade her honey bees in for Jerusalem crickets.

It's not a pretty sight--the Varroa mite attacking a honey bee.
Beekeepers are accustomed to seeing the reddish-brown, eight-legged parasite (aka "blood sucker") in their hives.
UC Davis bee breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, is among those who've declared war on the mites.
She's carrying out an intensive and comprehensive breeding and selection program aimed at developing honey bees that are resistant to pests and diseases.
The Varroa mite is a serious pest of honey bees worldwide, spreads diseases, and can weaken and destroy the colony. It is no doubt one of the culprits involved in colony collapse disorder, a mysterious phenomenon characterized by honey bees abandoning the hive.
Here's what the Varroa mite looks like attacking an immature bee.

A tip of the bee veil to Susan Cobey.
Cobey, bee breeder-geneticist and manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility at the University of California, Davis, has won the 2009 “Outstanding Service to Beekeeping” award from the Western Apicultural Society (WAS).
Cobey received a plaque at the organization’s 31st annual conference, held last week in Healdsburg.
Known world-wide for her expertise in instrumental insemination and stock improvement, she trained under Harry Laidlaw (1907-2003) of UC Davis, considered “the father of honey bee genetics.”
WAS president and Extension apiculturist Eric Mussen of the UC Davis Department of Entomology faculty, presented her the award, praising her expertise, dedication and passion.
Cobey is well-known in the beekeeping industry. Her advanced beekeeping courses on queen bee rearing and queen bee insemination draw students from throughout the world.
“It’s a special honor to receive this award, especially since my return to California,” said Cobey, who participated in the first WAS conferences.
Cobey joined the UC Davis Department of Entomology in May 2007, after a career spanning 17 years as staff apiarist at the Rothenbuhler Honey Bee Laboratory, Ohio State University.
Cobey developed the New World Carnolians stock, a dark race of honey bees, in the early 1980s by back-crossing stocks collected from throughout the United States and Canada to create a more pure strain. A current focus of her research includes selecting and enhancing this stock to show increasing levels of resistance to pests and diseases.
Of her research, she says: “Over time, it has proven very productive, winter hardy, well-tempered and more resistant to pests and disease. Genetic diversity, the raw tools for selection, is critical in maintaining colony fitness and resisting pests and diseases.”
She is enhancing the stock, now in its 27th generation, with importation of semen from the German Carnica Association.
Cobey is the 28th person to receive the WAS award, and the sixth from UC Davis. Harry H. Laidlaw Jr. received the award in 1980; Robert Page in 1989; Norman Gary in 1990; Eric Mussen in 1991; and Christine Peng in 2002. Page (now with Arizona State University), Gary and Peng are all emeriti professors.
Mussen and Gary co-founded WAS in 1978 as a non-profit, educational organization designed specifically to meet the educational needs of beekeepers from Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming; the provinces of Alberta, British Columbia, Saskatchewan, and the Yukon; and the states of northern Mexico.

High Honor
