Honey bee health key to wellbeing of important species
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 fruits of their labors
Summer time...and the livin' is easy.
But not for the bees. Worker bees, which live about four to six weeks, literally work themselves to death gathering nectar, pollen, propolis (plant resin) and water to bring back to their colony.
So, when you sit down to summer meals, you can thank a bee.
Extension apiculturist Eric Mussen of the UC Davis Department of Entomology and Nematology, says one-third of the American diet is pollinated by bees. Without bees, we'd be eating such wind-pollinated grains as wheat and rice.
Our gardens and orchards yield such favorites as carrots, cucumbers, onions, apples, grapefruit, oranges, pears, cherries, raspberries, strawberries, blueberries, lima beans, sunflowers and almonds.
All pollinated by honey bees.
Cole crops, such as cabbage, Brussel sprouts, collards, kale, kohlrabi, spinach, chard and broccoli?
All pollinated by honey bees.
Even milk and ice cream are linked closely to the honey bee. Cows feed on alfalfa, which is pollinated by honey bees (along with other bees). Ice cream ingredients usually include fruits and nuts, other bee favorites.
The ever-popular fruit salad features blueberries, apples, oranges and pomegranates.
All pollinated by honey bees.
An apple a day may keep the doctor away, but without the bees, we'd have no apples.
Love apples and honey? Here are two recipes from the National Honey Board celebrating both honey and apples.

Did you catch the buzz?
Did you catch the buzz?
It's still a troubling scene for our nation's honey bees, but it appears that the total losses for the 2011-2012 winter aren't as bad as they could be.
In other words, managed honey bee colonies appear to be holding their own. Overall, they didn't take a sharp dive last winter.
The annual survey, conducted by the U.S. Department of Agriculture (USDA), the Bee Informed Partnership, and the Apiary Inspectors of America shows that the honey bee colony losses averaged 30 percent for the winter of 2011-2012.
Compare that to 34 percent for the 2009-2010 winter, 29 percent for 2008-2009 winter; 36 percent for 2007-2008, and 32 percent for 2006-2007.
Kim Kaplan of the Agricultural Research Service (ARS) of USDA wrote in a May 23 news release that 5,572 beekeepers responded to the survey, which covered the period from October 2010 to April 2011. These 5,572 beekeepers, he said, manage more than 15 percent of the country's estimated 2.68 million colonies.
As ARS entomologist Jeff Pettis, who helped conduct the study, said: "The lack of increase in losses is marginally encouraging in the sense that the problem does not appear to be getting worse for honey bees and beekeepers."
Pettis is a familiar name among scientists, beekeepers and the beekeeping industry. He leads the USDA's chief research agency, the Bee Research Laboratory, in Beltsville, Md.
ARS plans to publish a complete analysis of the data later this year, Kaplan reports, but for now, we know that the average losses didn't fall below 30 percent. Some beekeepers, however, recorded much heavier losses.
Why care about the declining bee population?
As author Norm Gary, emeritus professor of entomology at UC Davis, says in his book, Honey Bee Hobbyist; The Care and Keeping of Bees, "Bees play a fundamental role in food production. About one-third of the food we eat, at least in the United States, can't be produced without pollination by honey bees. Fruits, vegetables, berries, some fiber crops, domestic animal feed, and oil seed crops would be in extremely short supply without honey bee pollination."
And almonds. California, the world's largest producer of almonds, has some 800,000 acres of almonds and each acre requires two hives for pollination. Without bees, no almonds.
"Can you imagine the impact on our food supply and diet if honey bees weren't available for pollination?" Gary asks. "Without them, the human diet would consist mostly of grains and fish."
Think wheat, rice and fish.
No honey, either.
Speaking of honey, you might like to try this Cranberry Oat Bread recipe provided by the National Honey Board. It hasn't been a honey of a winter for the nation's bees, but this is a honey of a recipe.
Cranberry Oat Bread
3/4 cup honey
1/3 cup vegetable oil
2 eggs
1/2 cup milk
2-1/2 cups all-purpose flour
1 cup quick-cooking rolled oats
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon salt
1/2 teaspoon ground cinnamon
2 cups fresh or frozen cranberries
1 cup chopped nuts
Combine honey, oil, eggs and milk in large bowl; mix well. Combine flour, oats, baking soda, baking powder, salt and cinnamon in medium bowl; mix well. Stir into honey mixture. Fold in cranberries and nuts. Spoon into two 8-1/2 x 4-1/2 x 2-1/2-inch greased and floured loaf pans.
Bake in preheated 350 degrees oven 40 to 45 minutes or until wooden toothpick inserted near center comes out clean. Cool in pans on wire racks 15 minutes. Remove from pans; cool completely on wire racks. Makes 2 loaves.

December farm stories
Davis Wednesday afternoon farmers' market can be quiet in December, so what better time to learn a little about what's going on back at the farms? Every farmer I talked with today had delicious treats to sell and a story to tell. Here are a few:
The fuzzy green fruit for sale today from Stenzel's Kiwi Farm was harvested late in October and has been held in cold storage at 32 degrees since then. The fruit will last about six months stored this way, allowing Stenzel to bring out what he needs, grade it by size, let it ripen a little, but sell it while it's still firm. When you bring your kiwis home, let them ripen three or four days more for the best flavor.
Give it a try - visit your local winter farmers market and learn some new stories!

Honey, I'm homemade!
Well, they enabled it.
Take a look at one of May Berenbaum’s favorite honey recipes and you’ll know why she calls it “Apiscotti” or “Bee-Enabled Biscotti.”
Seven of the 12 ingredients (butter, honey, almond extract, nutmeg, cranberries, cherries, and almonds) depend on the pollination services of the honey bee, Apis mellifera.
May Berenbaum, professor and head of the University of Illinois Department of Entomology, kindly shared the recipe below.
You may know her as an entomologist, an administrator, a honey bee researcher, a book author, a columnist (American Entomologist), an opinion page writer (see her piece on bed bugs in the New York Times) a wife and a mother.
But not a beekeeper
“Although I’m an entomologist, I’m not in any sense of the word a beekeeper,” she writes in her newly published book, Honey, I'm Homemade: Sweet Treats from the Beehive Across the Centuries and Around the World, a project that benefits the University of Illinois Pollinatarium, the nation's first free-standing science outreach center devoted to flowering plants and their pollinators.
“At various intervals during my life I’ve been a bee landlord—other entomologists have kept bees on property I own—but I’ve never personally had a hive I could call my own or been involved in the production of honey. Truth be told, I’m a little afraid of honey bees—and not just because they can sting. The stings are a manageable risk. What I find unnerving about bees is how eerily talented they are and how profoundly different from the million-plus other species of insects.”
Berenbaum, a fellow of the American Academy of Arts and a member of the National Academy of Sciences, says that honey is a unique food “because of its power to evoke a particular time and place. Every time it is collected from a hive, honey takes on the nuanced flavors of a particular set of flowers--clover, orange blossoms, buckwheat, or others--at a certain point in time processed and stored by a particular group of bees. Honey is not just a snapshot of a time and place--it's the taste of a time and place, and it lends its flavors to the delectable baked goods and other treats found here.”
Indeed, we’re glad to see a project benefitting the Pollinatarium and heralding the humble honey bee. In pollination services alone, honey bees contribute approximately $20 billion annually to American agriculture. And the value of the 2008 honey crop totaled more than $226 million, Berenbaum points out.
Without the honey bee, there would be no Apiscotti—or most of the other foods we enjoy. And that would bee disastrous.
Here’s her recipe for Apiscotti.
Apiscotti (Bee-enabled Biscotti)
1/2 cup butter
1/2 cup sugar
1/4 cup honey
3 eggs
1/2 teaspoon salt
1 teaspoon almond extract
1/4 teaspoon nutmeg
2 teaspoons baking powder
2 1/2 to 3 cups flour
1/2 dried cranberries, chopped
1/2 cup dried cherries, chopped
1/2 cup blanched sliced almonds, chopped
Preheat oven to 350 degrees. Cream sugar and butter together; mix in honey until smooth. Beat eggs until frothy and then add salt, almond extract, nutmeg, and baking powder. Combine the sugar-butter mixture with the egg mixture. Add flour until dough is a consistency that can be handled. Refrigerate dough for 1 hour or more.
Divide chilled dough into 3 parts and flatten each third into a rectangle (use additional flour to make handling easier if necessary). Place a line at the center of each flattened section of dough and fill with chopped cherries, cranberries, and nuts. Fold the sides of each rectangle over to form a loaf, filling in center, and seal.
Place loaves on greased cookie sheet at 350 degrees for 45 minutes to 1 hour, or until golden brown. Slice on a slant while hot into 1/2-inch slices. For crispier slices, return to oven for 5–10 minutes, or until golden brown (the color of a honey bee).
