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.

To bee or not to bee depends on the crop

Bees do it. Birds do it. Even bats do it. They all help plants reproduce by carrying pollen from one flower to another. Beetles, butterflies, wasps, flies and moths are also pollinators.

About 35 percent of the food we eat depends on the assistance of bees to pollinate plants and trees so they will produce fruit, nuts or vegetables. It takes 1.6 million colonies of honey bees to pollinate California's 800,000 acres of almond trees.

Our food choices would be dramatically reduced if bees weren't around to pollinate. To illustrate what the produce section of a grocery store would look like in a world without bees, Whole Foods Market removed the products that depend on pollination from one of its stores and took a photo. See the difference: http://ucanr.tumblr.com/post/84164840510/kqedscience-whole-foods-shows-customers-the. Without bees, more than half the fruits and vegetables were eliminated.  

Honey bees and other pollinators are being threatened by the drought, disease, mites, loss of habitat and food sources, according to Eric Mussen, UC Cooperative Extension specialist in the Department of Entomology at UC Davis and bee expert.

But not everyone wants help from pollinators. To produce seedless fruit, some citrus growers cover their mandarin trees to keep out bees because the mandarins, or tangerines, produce seeds if the tree is pollinated. Most consumers prefer their mandarins to be seedless.

Beth Grafton-Cardwell, UC Cooperative Extension specialist in the Department of Entomology at UC Riverside and director of Lindcove Research and Extension Center, talks about the role of pollinators in California agriculture in this video: http://www.youtube.com/watch?v=8suOt5PnzWc&feature=youtu.be.

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.

Apple honey crisp

2 lbs. apples, quartered and sliced (1-1/2 quarts)
1/2 cup plus 1/4 cup  honey, (separated)

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:

Did you know that Gridley is the kiwi capital of America? There used to be a kiwi festival and a kiwi queen, but that all got too expensive for Gridley's kiwi farmers quite a few years ago, Frank Stenzel reports. He's getting ready to start pruning his 14 acres of kiwi vines next week; pruning will take a crew of 12 about two weeks. After pruning, each of the 25 or 30 canes on each kiwi vine will need to be tied to a trellis, very much like grape vines, to be ready for next year's growth.

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.

Now that the weather is getting colder, the older chickens at Annette Jones' Islote Farms in Esparto have started molting. For a few weeks, they will lose feathers and stop laying eggs. But Jones isn't worried; in fact, she planned for this. Younger hens are picking up the slack because they hatched later in springtime and are just starting to lay eggs in December and January. The older hens can take their much needed break while the youngsters get busy.  The fresh eggs from the younger hens are available at the market today in small and medium sizes. When springtime comes, all the birds will be laying again and eggs will be plentiful.

On Federico Toledo's Toledo Farm in Lodi, his son, brother, brother-in-law and other family members are busy planting this month - cabbages, broccoli, cauliflower, spinach, beets, cilantro, carrots, onions and curly parsley. What they're planting now will be at the farmers markets in March, April and May, if the weather cooperates. The 20 long rows of onions going in now will yield green onions in February and March, full-size fresh onions in April and May, and then dry onions in June and July. Today's market table has stories too: The last red tomatoes of the year are for sale today; they were picked green in November and ripened with a heater. The winter squash was actually grown in summer and harvested in August - it gets sweeter over the months and keeps well in winter. The persimmons, grapefruit, lemons and apples were all fresh-picked by the farm family.

All the rice has been harvested now at Robin Harlan's Bullfrog Farms in Winters, and the 3,000 hives of Bullfrog Bees are getting pollen patties to make it through the winter since there aren't enough blossoms to keep them fed without help this time of year. There's time now for bottling the honey; it's been stored in big stainless steel barrels since the Harlans harvested it in the summer. Bullfrog Farms grows more than 200 acres of almond trees which start blooming in January, so the bees will have blossoms very soon to pollinate and pollen to gather for more honey. After working in the Bullfrog orchards, they'll go to Blue Diamond almond orchards, and then to orange groves in Winters. Local honey is the sweet result of these hard-working bees.

Todd Evans works at certified organic Mount Moriah Farms in Clements. Today he's selling crisp Fuji and Pink Lady apples. Up until two days ago, Evans, farm owner Steve Smit, and a couple of other guys were harvesting apples. Now they're getting ready to prune all the trees, which will take the four of them about a month. The apples should last in storage until about May, just long enough for the cherries to be ready.
