Honey bee geneticists with long ties to UC Davis are putting together those missing pieces of the puzzle involving bee chromosomes. Newly published research by a team of Germany-based honey bee geneticists, collaborating with Robert Eugene (“Rob”) Page Jr., of Arizona State...
"The honey bee genome,” Robert Page Jr. explained, “is composed of about 15,000 genes, each of which operates within a complex network of genes, doing its small, or large, share of work in building the bee, keeping its internal functions operating, or helping it function and behave in its environment.

That simple request, prefaced with a term of endearment for good measure, means there's honey on the table.
And well there should be. As the daughter, granddaughter and great-great granddaughter (and beyond) of beekeepers, I grew up with honey on the table. (And on my fingers, face and clothes.)
My favorite then was clover honey from the lush meadows and fields of our 300-acre farm in southwest Washington. My favorite now is Northern California yellow starthistle honey, derived from the blossoms of that highly invasive weed, Centaurea solstitialis, which farmers hate (and rightfully so) and beekeepers love.
“Almost every honey has its own unique flavor-- even when it is the same varietal,” says Amina Harris, director of the UC Davis Honey and Pollination Center. “There are characteristics we learn to look for, but even within that variety, the honey will differ from each area collected. For instance: avocado honey is known for being very dark amber with a flavor reminiscent of molasses, licorice or anise. However, once you start tasting a selection, some will taste like blackstrap molasses and very black licorice. Others will have almost a fruity flavor like dried figs or prunes. Most folks can't tell the difference – and then there are the honey nerds, like me!”
“My favorite all-around honey is one I keep returning to. I love sweet clover from the High Plains with its cinnamon hit —the spicy characteristic is just something I love,” Harris said. “My favorite ‘shock honey' is coriander. Collected near Yuba City, this seed crop gives us a honey that is like walking through a spice bazaar with hints of cardamom, cinnamon, allspice, nutmeg, coriander and — chocolate.”
The UC Davis Honey and Pollination Center, located in the Mondavi Institute for Wine and Food Science on Old Davis Road, periodically offers courses on the sensory evaluation of honey, as well as honey tastings. Next up: the center will host free honey tastings at its home base during the 105th Annual Campuswide Picnic Day on April 13, and at the California Honey Festival in downtown Woodland on May 4. Another popular honey tasting: California Extension apiculturist Elina Lastro Niño, based in the UC Davis Department of Entomology and Nematology, hosts a honey tasting at Briggs Hall during the annual Picnic Day.
There's more to honey than meets the eye — or the palate. The Honey and Pollination Center recently hosted a three-day Sensory Evaluation of Honey Certificate Course last October, using “sensory evaluation tools and methods to educate participants in the nuances of varietal honey,” Harris said. Northern California public radio station KQED spotlighted the course on its “Taste This” program.
And we owe it all to honey bees.
Pollination ecologist Stephen Buchmann of the University of Arizona (who received his doctorate in entomology from UC Davis, studying with native pollinator specialist Robbin Thorp), writes in his book, Honey Bees: Letters from the Hive, that each worker bee “may make four to ten or so flights from the nest each day, visiting hundreds or many thousands of flowers to collect nectar and pollen. During her lifetime, a worker bee may flown 35,000 to 55,000 miles collecting food for her and her nest mates. One pound of honey stored in the comb can represent 200,000 miles of combined bee flights and nectar from as many as five million flowers.”
Take a 16-ounce jar of honey at the supermarket. That represents “the efforts of tens of thousands of bees flying a total of 112,000 miles to forage nectar from about 4.5 million flowers,” writes Buchmann.
Of course, we primarily appreciate honey bees for their pollination services (one-third of the food we eat is pollinated by bees) but honey is more than just an after thought.
It's been described as “liquid gold,” “the nectar of the gods” and “the soul of a field of flowers.” Frankly, it's nothing short of miraculous.
And well it should be.

Our friends the honey bees make it possible for us to devour an abundance of almond products. In 2016 the California almond crop totaled 2.15 billion pounds valued at $5.2 billion. Growing 80 percent of the world's almonds in California takes a lot of honey bees for pollination, roughly two hives for every acre of almond trees. It's estimated that California has 1.3 million acres of almonds, stretching 400 miles between Bakersfield and Red Bluff.
California is rated in the top five honey producing states in the nation. The U.S. per capita consumption of honey is around 1.3 pounds per year. Our buzzing friends visit millions of blossoms, making pollination of plants possible and collecting nectar to bring back to the hive. Lucky for us bees make more honey than their colony needs allowing beekeepers the opportunity to remove the excess honey and bottle it for us to enjoy.
Bees are animals too
Bees are one of our planet's most important animals. They produce honey and they are the primary managed pollinators for a majority of high value specialty crops grown in the contiguous states of California and Oregon, such as nuts, stone fruits, vegetables, and berries. A problem looms for our animal friends, the bees. Colony losses are high due to a variety of environmental and biological causes including bacterial diseases. Historically, beekeepers have self-prescribed antibiotics to control these diseases.
Enter UC Davis and Oregon State University to aid beekeepers in addressing the problem of antibiotic resistance and antimicrobial use in the feed or water of food-producing animals, namely, protecting the health and safety of bees. The overall strategy leads to a safer food supply because the potential for antibiotic resistance is reduced.
The Western Institute for Food Safety and Security (WIFSS), UC Cooperative Extension, and UC Davis School of Veterinary Medicine are partnering with Oregon State University in a USDA funded multi-state specialty crop project to develop CE training for veterinarians on bee health and antibiotic use — a practice that is now regulated under the Veterinary Feed Directive (VFD). The project will offer a comprehensive bee biology online course and train-the-trainer practical training for veterinarians and apiculture educators. The ultimate goals are to protect the specialty crop — honey — from becoming contaminated with antibiotic residues; to protect the health and safety of bees, which are essential to California agriculture; and, finally, to support veterinary oversight in the use of antibiotics, which will lead to an overall reduction of antibiotic resistant bacteria in the environment.
The $483,278 award will address the unique needs of the beekeeping industry that have been experiencing high colony losses since 2006. It will also focus on new rules established by the U.S. Food & Drug Administration on the use of antibiotics which are used to control certain diseases affecting bee colonies.
The principal investigator is Elina L. Niño, a UC Cooperative Extension specialist with the UC Davis Department of Entomology and Nematology. Project leader is Bennie Osburn, director of outreach and training at WIFSS. Collaborating in the project is Jonathan Dear, from the Department of Medicine and Epidemiology at UC Davis School of Veterinary Medicine, and the partner state collaborator is Ramesh Sagili from the Department of Horticulture at Oregon State University. A team of graphic and instructional designers from WIFSS will work with Drs. Niño, Dear, and Sagili, to translate the science into user friendly information for veterinarians and beekeepers.
Educating about honey bee health
Dear who is collaborating with WIFSS to produce an online and hands-on module to train veterinarians about beekeeping and honey bee health, points out that, “Honey bees are such an important part of our economy and, like any food producing animal, they can be affected by preventable and treatable diseases.”
He is enthusiastic about the project and says, “Our hope is that by educating veterinarians about honey bee health, they can play a key role in maintaining the health and wellbeing of this important species.”
With the efforts of extension specialists, veterinarians, and graphic and instructional designers, beekeepers and veterinarians will work together to navigate the VFD regulations, and consumers will continue to enjoy nature's sugar.
The humming sound of busy honeybees filled the fall air, darting back and forth as I followed longtime beekeeper Randy Oliver around his bee yard. I was there to learn about a new issue for local beekeepers. Oliver explained that local honeybee colonies have been robbed of their honey in places they have been kept year-after-year for several decades. Robbed?? Yes, by other honeybees, from hives from other parts of California. In the last couple years, numerous out-of-area hives have been placed in close proximity to local hives. Oliver, along with local beekeepers, presented a draft proposal to the Nevada County Ag Advisory Commission, which recommended an emergency beekeeping ordinance to county supervisors.
Oliver explained that the proposal calls for a minimum of a 2-mile radius around each existing apiary location and a 45-hive maximum in each location. All bee hives in Nevada County must be registered by the Ag Commissioner in January each year. This ordinance is designed to provide the resources and “teeth” to protect local bees and their food sources. Put in rancher terms, imagine that you had your cattle on pasture, someone saw your cattle grazing and decided to dump off 100 cows in the same pasture because it looked like a good food source. “This is beekeepers regulating themselves” said Oliver. The ordinance would not cost taxpayers and is funded by beekeepers themselves. Hobby beekeepers would be exempt from the registration fees and existing hives would be grandfathered in. Another issue with having bee colonies in close proximity is the potential for infection and mite drift into hives. Oliver explained the dangers of reintroducing a bacterial disease called American foulbrood that is nearly eradicated in Nevada County. This issue may also be of concern in Placer County.
So what does this have to do with local farmers and ranchers? If someone asks permission to put honeybee hives on your land, or leaves a note on your gate, contact your Nevada County Beekeepers Association or search “Honey” on the Placer Grown website to find local beekeepers.
A report released in March by the National Agricultural Statistics Service (NASS) stated that California produced 13,735,000 pounds of honey in 2017, worth more than $28.5 million dollars. Beekeeping is an important agricultural activity in this area. Hive rentals to almond growers rather than honey provide the major income for beekeepers, but honey is an important product in the foothills.
