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.
If you attend the 95th annual UC Davis Picnic Day on Saturday, April 18 and stop by Briggs Hall between 10 a.m. to 4 p.m., you'll get a taste of honey.
In fact, six tastes of honey.
Extension Apiculturist Eric Mussen, a 32-year member of the UC Davis Department of Entomology faculty, will provide six different flavors of honey: Eastern buckhweat, redwood forest, orange blossom, California sage, Northwest raspberry and Georgia gallberry.
Here's the procedure: you scoop up six toothpicks, one per honey sample. You dip a toothpick into a container of honey (no double-dipping!) and then you discard the toothpick..
The darker honeys are Eastern buckwheat, redwood forest and Georgia gallberry; medium color, Northwest raspberry; and the lighter ones are orange blossom and California sage.
You can almost catch the buzz as you taste the honey. Honey differs in flavor and color, depending on the nectar source (blossoms) that the honey bees visit. Some 300 different varieties of honey are available for sale in the United States. In general, the lighter the color, the milder the flavor.
For more information on honey, visit the National Honey Board's Web site.
Questions about bees? Colony collapse disorder? Bee behavior? Queen bees, worker bees and drones? Why beekeepers wear light-colored clothing and don't eat bananas before visiting the hive? Mussen will be happy to answer them.

If you built it (a field of dreams), they will come.
And if you bring flowers, that's all the bettter.
Melissa "Missy" Borel, program manager of the California Center for Urban Horticulture, UC Davis, and a strong proponent of bee friendly plants, brought salvia, lavender (Otto Quast Spanish lavender) and some stalked bulbine (Bulbine frutescens) to a television interview today at the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis.
Darsha Philips and camerman Andrew Faulk of Fox 40, Sacramento were there to interview her along with Lynn Kimsey, professor and chair of the UC Davis Department of Entomology and director of the Bohart Museum of Entomology; and Cooperative Extension apiculturist Eric Mussen, a 32-year member of the UC Davis Department of Entomology faculty..
Missy Borel placed the three potted plants atop a hive while waiting for the interview. It didn't take long for the honey bees to find the unexpected treat! They lavished the lavender, salivated over the salvia, and stalked the stalked bulbine.
Meanwhile, concern about the declining honey bee population continues. A third of the food we eat is pollinated by bees. Bee nutrition has never been so important. The bees are seeking nectar, pollen and water to bring back to their hives.
Want to select bee friendly plants for your garden? Missy Borel compiled this list during the Haagen-Daz Honey Bee Haven Design Competition. (See pages 7, 8 and 9 of the PDF). See more information on the winning design on the UC Davis Entomology Web site. The new garden will be located next to all the hives at the Laidlaw facility.
When the half-acre bee haven is completed, the bees won't have far to go to gather nectar and pollen all year around. Look for the dedication sometime in October.

A honey bee exhibit at the 133rd annual Dixon May Fair featuring Cooperative Extension Apiculturist Eric Mussen has just won a top regional honor.
The exhibit, housed appropriately in the floriculture building, won second place in the Western Fairs’ Association’s non-competitive exhibit category. WFA represents fairs and festivals in 27 states and
“The honey bee exhibit was a first at the Dixon May Fair and very popular,” said Ester Armstrong, the fair’s interim chief executive officer. “Dr. Mussen drew large, interested crowds, all wanting to know about the plight of the honey bee.” A record 89,000 attended the four-day fair, the oldest running fair in
Mussen, a University of California apiculturist and member of the UC Davis Department of Entomology faculty for the past 32 years, fielded questions from fairgoers. He also provided educational displays of bees and beekeepers.
Bee breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis, and research associate Kim Fondrk loaned the fair a bee observation hive, a glassed-in facility showing the queen bee, workers and drones.
Over the last two years, individual beekeepers have reported losing 30 to 100 percent of their bees due to a mysterious phenomenon known as colony collapse disorder. Honey bees pollinate one third of the American diet.

It makes sense that one of the oldest insects should be at the state's oldest fair. . The oldest known bee, found encased in amber in Burma, is thought to be 100 million years old. The specimen is at least 35 to 45 million years older than any other known bee fossil, scientists say./o:p>/st1:address>/st1:street>/st1:city>/st1:city>/st1:address>/st1:street>/u2:p>/st1:place>/o:p>/u2:p>/st1:placename>/st1:placetype>/st1:placetype>/st1:place>/st1:placename>/st1:place>/st1:country-region>/st1:country-region>/st1:place>/st1:placetype>/st1:placetype>/st1:placename>/st1:placename>/st1:place>/st1:place>/u2:p>/o:p>/u2:p>/u2:p>/span>/o:p>/u2:p>/u2:p>/o:p>/u2:p>/u2:p>/st1:state>/st1:place>/o:p>/u2:p>/st1:place>/st1:country-region>/st1:country-region>/st1:place>/span>/o:p>
The BBC this week examined colony collapse disorder (CCD), a mysterious phenomonen characterized by bees abandoning their hives. The adult bees buzz off, leaving the brood and stored food behind. They do not return.
Many bee specialists believe it's not just one thing causing CCD--it's a combination of factors or a "perfect storm": parasites, pesticides, malnutrition, stress, diseases and global weather changes.
The blood-sucking varroa mite, a parasite of honey bees, is a contributing factor in the decline of bee health.
When the BBC interviewed Cooperative Exension Apiculturist Eric Mussen of the UC Davis Entomology Department faculty about varroa mites, he said that the European or western honey bee doesn't "do a good job" of removing them. To a human, the varroa mite would be about the size of a softball "running around on you."
The varroa mite, Mussen said, is problematic because of three things:
1. It sucks the so-called bee blood, making the bee nutritionally weaker
2. It interferes with the immune system
3. The varroa can get viruses on its mouthparts so it inoculates bees with viruses as it travels from one bee to another.
Listen to Mussen talk about the varroa mite as he examines it under a microscope. Then imagine a softball-sized bloodsucker on you.
