National Honey Bee Day is Saturday, Aug. 19 and you're invited to join this oh-so-sweet celebration!
Launched in 2009, National Honey Bee Day takes place on the third Saturday of August. The event originated when a small group of beekeepers petitioned the U.S. Department of Agriculture "to honor" the honey bees and beekeepers.
HoneyLove.org, a Los Angeles-based honey bee educational non-profit organization, manages National Honey Bee Day and boosts "the educational outreach, community action and advocacy efforts to protect the health and well-being of honey bees," according to its website.
California Master Beekeeper Program. While we're honoring bees, we should also honor the UC Davis-based California Master Beekeeper Program (CAMBP), founded and directed by Elina Lastro Niño,associate professor of Cooperative Extension and a member of the faculty of the UC Davis Department of Entomology and Nematology.
"The award seeks to highlight teams who actively develop and encourage faculty/staff partnerships and as a result are able to make notable contributions to UC Davis that contribute to the University's Mission of Teaching, Research, and Service; and who exemplify outstanding achievement and/or service," according to Staff Assembly officials.
At the time of the nomination (March 15, 2023), CAMBP had
- Given 32,000 hours of volunteer time (Beneficial Educational Experiences) and served 186,630 individuals in education, outreach and beekeeping mentorship. If a volunteer hour is worth $26.87, the program has given $859,840 back to the state of California in service of science-based beekeeping and honey bee health.
- Enrolled 185 Honey Bee Ambassadors (a level established in 2021), 494 Apprentice, 93 Journey level candidates and certified 20 Master level beekeepers. There are 12 members in 2023 participating in their Master Capstone projects.
- Recorded 3752 hours since the team began tracking Continuing Education Experiences in 2020.
- Embarked on a project updating a safety manual.
National Honey Bee Day is also a good opportunity to learn about bees, our mini-agricultural workers that pollinate one-third of the food we eat.
The book includes 16 color plates (images contributed by Kathy Keatley Garvey), spotlighting a bee egg, bee castes, swarms and almond pollination, among others.
Princeton University Press bills the book as "the first up-to-date general reference of its kind published in decades. It is a must-have resource for social insect biologists, scientifically savvy beekeepers, and any scientist interested in bees as a model system."
Among his many honors and recognitions, Johnson was part of The UC Davis Bee Team that won the 2012 Team Award from the Pacific Branch, Entomological Society of America. Other members: Extension apiculturist Eric Mussen (1944-2022); systematist/hymenopterist Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology; native pollinator specialist Robbin Thorp (1933-2019) emeritus professor of entomology; and pollination ecologist Neal Williams (now professor) who specializes in pollination and bee biology.
Hear that buzz?
Are you ready for National Honey Bee Day?
It's held the third Saturday of August and that's tomorrow.
Launched in 2009 by a small group of beekeepers petitioning the U.S. Department of Food and Agriculture (USDA), the day basically "honors" honey bees and beekeeping. We first observed National Honey Bee Day on Aug. 22, 2009 (the fourth Saturday of August), but it is now permanently celebrated on the third Saturday of August.
It's a "buzzworthy" day to celebrate our tiniest agricultural workers. One-third of the food we eat comes from crops pollinated by honey bees, including almonds, apples, plums, pomegranates, onions, strawberries and much more.
"Honey bees play a critical role in agricultural production and pollinate dozens of food producing crops in the United States," according to UC Davis-based scientists. "In the U.S., honey bees account for $15 billion in added crop value."
Show me the honey? Okay. In 2019, U.S. honey bees produced about 157 million pounds of honey worth a total value of $339 million, according to the USDA. California ranks 5th in the nation in honey production.
At UC Davis, Extension apiculturist Elina Lastro Niño of our Department of Entomology and Nematology faculty, researches honey bees, and helps beekeepers and consumers. Her laboratory research interests include honey bee biology, health, breeding, behavior, reproductive physiology, genomics, chemical ecology and sociology of beekeeping. Check out her lab webpage on "Lending Bees and Beekeepers a Helping Hand." Niño, who serves all of California as the state's one and only apiculturist, also founded and directs the California Master Beekeeper Program, heralded for "using science-based information to educate stewards and ambassadors for honey bees and beekeeping."
Question: how many images do you have of honey bees pollinating different California crops? Here are a few.
It's National Honey Bee Day or National Honey Bee Awareness Day, launched in 2009 by newly appointed U.S. Secretary of Agriculture Thomas Vilsak during his first year of office with the Obama Administration.
The goals are the same as those in 2009:
- Promote and advance beekeeping
- Educate the public about honey bees and beekeeping
- Ensure that the public is aware of environmental concerns affecting honey bees
It's a day when we applaud our bees, and the bee scientists, beekeepers, commercial breeders, and all the educational, scientific and research organizations that friend them, fund them, or fuel them.
Indeed, one third of the food we eat is pollinated by bees. What many folks don't realize is that honey bees are not native to the United States. European colonists brought them here in 1622, and it wasn't until 1853 when a beekeeper in the San Jose area introduced them to California.
Statistics provided by the National Honey Bee Day officials, help tell the story of the industry:
- For every 100 beekeepers, 95 percent are hobbyists, 4 percent are sideliners, and 1 percent are commercial beekeepers.
- Beekeeping dates back at least 4500 years.
- Beekeeping can be a sustainable endeavor.
- Renting bees to farmers in need of pollination generates a source of income.
- Beehives are kept on farms, in backyards, on balconies, and high-rise rooftops, all across the country.
Bees will also take center stage at the 40th annual conference of the Western Apicultural Society (WAS) at the University of California, Davis. The conference, to take place Sept. 5-8 in the Activities and Recreation Center, is quite special because the organization was founded at UC Davis. WAS president is Extension apiculturist emeritus Eric Mussen of the UC Davis Department of Entomology and Nematology promises an educational program, complete with speakers, networking, tours and a silent auction.
Among those speaking will be Extension apiculturist Elina Lastro Niño, who will address the crowd on "The Impact of Varroa on Honey Bee Reproductive Castes (Queen Bee, Worker Bee and Drone): Where Will the Research Lead Us?” Her talk is at 8:30 a.m. on Thursday, Sept. 7.
Her research interests encompass basic and applied approaches to understanding and improving honey bee health and particularly honey bee queen health. Ongoing research projects include understanding the synergistic effects of pesticides on queen health and adult workers in order to improve beekeeping management practice, testing novel biopesticides for efficacy against varroa mites, a major pest of bees, and understanding the benefits of supplemental forage in almond orchards on honey bee health.

Writer Stephanie Parreira of the UC Statewide Integrated Pest Management Program (UC IPM) recently interviewed Niño for a podcast on bee pests and how to manage them, using IPM methods. The podcast appears on the UC ANR Green Blog. You can read the transcript here.
Niño mentioned that varroa mites remain the key concern of beekeepers. "In fact, when I first started my position here as an extension specialist at UC Davis, I asked beekeepers what is one of the things that they would like me to focus on, and about ninety-nine percent of them said varroa mites," she said in the podcast. "Varroa mites are a problem because they basically suck honey bee blood, or honey bee hemolymph, they transmit viruses, [and] they can suppress immune genes in developing and adult bees. So they can kill the colony, basically, if they're not managed properly. We have seen in our own colonies that if we do not treat or manage varroa mites, we know that we will lose that colony over winter."
If you're interested in attending the WAS conference and learning more about bees, you can register here. The speakers represent a wide spectrum of expertise and topics, from top-bar beekeeping to pesticides to how to keep your colonies healthy.

Well, not just pink. All other colors, too.
It's National Honey Bee Day on Saturday, Aug. 20.
That's when we officially celebrate the honey bee, Apis mellifera, which the European colonists brought to the Jamestown colony in Virginia in 1622. The honey bee didn't arrive in California until 1853 when a beekeeper brought colonies to the San Jose area.
How did National Honey Bee Day originate? U.S. beekeepers launched the event in 2009. In fact, they petitioned the U.S. Department of Food and Agriculture to recognize and pay tribute to its smallest agricultural worker, to spread awareness, and to advance beekeeping. This year's theme: "Beekeeping: A Hobby with a Sweet Taste."
When bees are out foraging, they bring back to the colony four essentials: nectar, pollen, water and propolis (plant resin that's used as a glue to seal small spaces).
But that's not the only thing they bring back to the hive.
They can also bring back pesticides that can kill or harm a colony.
Just in time for National Honey Bee Day, the University of California Statewide Integrated Pest Management Program (UC IPM), affiliated with UC Agriculture and Natural Resources, has developed and published Bee Precaution Pesticide Ratings "to help pest managers make an informed decision about how to protect bees when choosing or applying pesticides."
Cheryl Reynolds, senior editor/interactive learning developer for UC IPM, wrote a piece today on the UC Davis Department of Entomology and Nematology website about the project, first describing the UC IPM mission as "to protect the environment by reducing risks caused by pest management practices."
"The bee precaution ratings are based on the reported effects of a pesticide's active ingredient on adult honey bees or their brood," Reynolds wrote. "You can find and compare ratings for active ingredients including acaricides (miticides), bactericides, fungicides, herbicides, and insecticides."
"Ratings fall into three categories," she noted. "Red, or rated I, pesticides should not be applied or allowed to drift to plants that are flowering. Plants include the crop AND nearby weeds. Yellow, or rated II, pesticides should not be applied or allowed to drift to plants that are flowering, except when the application is made between sunset and midnight if allowed by the pesticide label and regulations. Finally, green, or rated III, pesticides have no bee precautions, except when required by the pesticide label or regulations."
Reynolds emphasized that the bee precaution pesticide ratings "are not the pollinator protection statements on the pesticide label."
"Each crop in the UC Pest Management Guidelines has links to the bee precaution ratings and provides guidance on how to reduce bee poisoning from pesticides," Reynolds pointed out.
Meanwhile, Happy National Bee Day! Thank a bee! And if you want to become a beekeeper, UC Davis offers classes.
If you've ever seen honey bees foraging on primrose, you may have seen something unusual.
What's with the pollen hanging below their hind legs as they buzz from primrose to primrose?
There's a reason for that.
Distinguished emeritus professor Robbin Thorp of the UC Davis Department of Entomology and Nemalogy alerted us to the reason.
"Note the stringy mass (mess) of pollen hanging below the hind legs of the bee," Thorp points out. "Honey bees have great difficulty in collecting (actually packing into their corbiculae) pollen from any large flowered species of Oenothera. The pollen grains are very large, more than 100 microns, and tied together with viscin threads to form a webby mass. This is ideal for transfer by hawkmoths where stringy masses get attached to their undersides as they probe for nectar."
"Oenothera pollen," Thorp says, "can be collected by some native bees where the scopae are modified to contain sparse simple hairs where the webby pollen can be easily stored. But the corbiculae of honey bees are not well suited to handle this webby stuff, since it will not pass neatly through the 'pollen mill' of the honey bee hind leg."
He recalls seeing the same situation when honey bees were working his desert evening primroses.
And speaking of honey bees, it's National Honey Bee Day on Saturday, Aug. 22.
Extension apiculturist (emeritus) Eric Mussen of the UC Davis Department of Entomology and Nematology, wrote a piece on a UC ANR blog published this week. He initially published it in the June 2013 edition of the UC IPM Retail Nursery & Garden Center IPM News but it's quite timely.
"The actual cause of honey bee decline is still uncertain," Mussen says. "What is known is a number of factors are probably involved. Honey bees are their most robust and able to best contend with stresses when well fed. In addition to water, honey bees require nectar sources for carbohydrates and a varied mix of pollens to provide proteins, lipids, vitamins, minerals, sterols, antioxidants, and other nutrients. Drought, flooding, and conversion of former foraging grounds into large agricultural monocultures, highways, airports, developments, and so forth have led to honey bee malnutrition in many locations."
"In the last 20 years beekeepers have been encountering a series of previously exotic pests that invade the hive and kill bees, such as the varroa mite; new honey bee diseases, including Nosemaceranae; and many viruses."
"Pesticides can also be involved in bee decline, especially when applied to plants when they are in bloom and bees are foraging," Mussen points out. "Many insecticides are highly toxic to bees including virtually all organophosphates, carbamates, and pyrethroids. If not killed in the field, foraging bees can collect residue-contaminated pollens and bring them back to the hive for immediate consumption or long-term storage. There are serious concerns over the chronic, sublethal effects of these residues on the physiology of immature and adult bees."
"A newer class of insecticides, the neonicotinoids, which include imidacloprid, clothianidin, and dinotefuran, also pose hazards for honey bees. These products are systemic materials that move through the plant and are included in the nectar and pollen of flowers when they bloom. Although the neonicotinoid residues may not kill bees immediately, they may have sublethal effects, such as suppressing immune and detoxification systems, causing bees to be more sensitive to other stresses."
If you want to know more about neonics, be sure to attend the UC Davis neonics conference on "Truth or Myth: Neonicotinoids and Their Impact on Pollinators: What Is the Science-Based Research?” from 10 a.m. to 4 p.m., Wednesday, Sept. 9 in the UC Davis Conference Center. UC Davis researchers and state officials will address the crowd, announced conference coordinator Dave Fujino, director of the UC Davis-based California Center for Urban Horticulture.
