That would be the varroa mite, Varroa destructor, an eight-legged external parasite that attacks and feeds on honey bees. Those mites can spread viruses and decimate a healthy colony.
How can you monitor, mitigate and manage them?
Extension apiculturist Elina Lastro Niño and her lab are hosting a short course on "Varroa Mite Management Strategies" from 9 a.m. to 4 p.m., Sunday, Oct. 13 at the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, University of California, Davis.
"Current beekeeping challenges call for all beekeepers to have a solid understanding of varroa mite biology and management approaches," said Niño, in describing the course. "We will dive deeper into understanding varroa biology and will devote majority of the time to discussing pros and cons of various means to monitor, mitigate, and manage this crucial honey bee pest."
The course, limited to 20 participants, will cover varroa biology, treatment options and chemical-free options. Participants are to bring their bee veil or suit. The $200 registration fee covers the cost of course materials, lunch and refreshments. The last day to register is Monday, Oct. 7. Click here to register.
Originating in Asia, the varroa mite is now found throughout most of the world. It arrived in Japan and the Soviet Union in the early 1960s and South America in the 1970s. From the 1970s to 1980s, it spread to South America, Poland, France, Switzerland, Spain, and Portugal. The pest was first detected in the United States in 1987, in Canada in 1989, and in 1992 in the United Kingdom. It has since spread to Ireland, New Zealand and Hawaii, but to date, has not been found in Australia.
The female is reddish brown, while the male is white. They measure 1–1.8 mm long and 1.5–2 mm wide.
The course is sponsored by the UC Davis-based California Master Beekeeper Program, (CAMBP). directed by Niño. The program uses science-based information to educate stewards and ambassadors for honey bees and beekeeping.

The California Master Beekeeper Program (CAMBP), directed by Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, is hosting two short courses: one on “Planning Ahead for Your First Hives” on Saturday, Aug. 3 and the other, “Working Your Colonies” on Sunday, Aug. 4 at the Harry H. Laidlaw Jr. Honey Bee Research Program.
Each will take place from 9 a.m. to 4 p.m. at the facility, which is located on Bee Biology Road, west of the central campus. The deadline to register is Thursday, Aug. 1.
“These courses are foundational to beekeeping husbandry excellence,” said Wendy Mather, program manager. “They are great for folks who are thinking about getting bees next season, as well as those who currently have bees and want to ensure they're doing whatever they can to ensure the success of their hives.”
The classes are not required to become a California Master Beekeeper, but are highly recommended, as “they will help folks prepare to become a science-based beekeeping ambassador,” Mather said. Instructors are Elina Niño and CAMPB educational supervisor Bernardo Niño, a staff research assistant in the Niño lab.
Planning Ahead for Your First Hives
“Planning Ahead for Your First Hives” will take place Saturday, Aug. 3 and will include both lectures and hands-on activities. Participants will learn what's necessary to get the colony started and keep it healthy and thriving. They will learn about bee biology, beekeeping equipment, how to install honey bee packages, how to monitor their colonies (that includes inspecting and monitoring for varroa mites) and other challenges with maintaining a healthy colony.
The course is limited to 25 participants. The $105 registration fee covers the cost of course materials (including a hive tool), lunch and refreshments. Participants can bring their bee suit or veil if they have one, or protective gear can be provided. For more information or to register, see https://registration.ucdavis.edu/Item/Details/572.
Working Your Colonies
“Working Your Colonies” will take place Sunday, Aug. 4 and will include both lectures and hands-on activities. Participants will learn what is necessary to maintain a healthy colony. Lectures will cover advanced honey bee biology, honey bee integrated pest management, and products of the hive. Participants also will learn about queen wrangling, honey extraction, splitting/combined colonies, and monitoring for varroa mites.
The course is limited to 25 participants per session. The $175 registration fee covers the cost of course materials, lunch and refreshments. For more information or to register, see https://registration.ucdavis.edu/Item/Details/559.
Participants can bring their bee suit or veil if they have one, or protective gear can be provided. All participants are to wear closed-toed and closed-heel shoes, long pants and a long-sleeved shirt.

(June 17-23 is National Pollinator Week.)
"How many? Does anyone know?"
No one did, but by the end of the Pollination Education Program, sponsored by CAMBP, all 72 youths from the Sutter Creek and Ione area of Amador County did: 20,000.
They also learned that there are 4000 species of bees in the United States, 1600 species in California, and 350 in Yolo County.
And they learned that pollinators include honey bees, bumble bees, butterflies, sweat bees, hummingbirds and syrphid flies.
"Can you all say entomologist?" Mather asked. "Does anyone know what entomology means?"
"Insects," said one youth.
"Yes, entomology is the scientific study of insects," Mather told them. That's what each and everyone of you is today: entomologists! Okay?
She explained the life cycle of a bee: from egg to larva to pupa to adult. "Males are called drones," she said. "Females are called worker bees."
Toward the end of the program, Mather told the students: "You are ready for the university. As soon as you graduate from high school, I hope to see you guys here. You are all excellent, very respectable, responsible and mature scientists. I want you to please take the knowledge that you gathered here today and share it with family and friends."
The Pollinator Education Program (PEP), developed two years ago by CAMPB director and Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, along with staff research associate Bernardo Niño, aims to provide a fun, immersive educational experience "to help kids of all ages understand the importance pollinators play in the lives of humans."
At the recent session, Mather shared data on native bees, explained the life cycle of a honey bee, encouraged students to be citizen scientists, and demonstrated how to carefully collect bee specimens with a bee vacuum in a catch-and-release activity.
Volunteer Robin Lowry managed the “Planting for Pollinators” and “Be a Beekeeper” station. Students tried on beekeeping suits and tested the equipment, including a smoker and hive tools.
Volunteer Julia Wentzel introduced the concept of "pollinator specialists" and engaged the students in creating a "pollinator" which they then used to transfer "pollen" to different shaped flowers. Diverse floral sources are integral to honey bee health, she said.
Matthew Hoepfinger, staff research associate in the Niño lab, opened a bee hive (inside a screened tent) and showed the students the queen, workers and drones.
Just before boarding the buses for home, the students sampled several varietals of honey. "This is really good!" a girl said. "I want more."
Ron Antone of the UC Master Gardeners of Amador coordinates the annual program, working with Amador school officials, parents and master gardeners. This year he coordinated two groups:
- Jackson Elementary. 62 third graders, 3 teachers, 2 aides, 3 parents and 2 Master Gardener volunteers from Amador County.
- Ione Elementary. 72 third graders, 3 teachers, 7 parents, 3 Master Gardeners and 3 volunteers from Farms of Amador.
The UC Davis Department of Entomology and Nematology operates the Häagen-Dazs Honey Bee Haven, with Elina Lastro Niño serving as the garden's faculty director and Christine Casey as the manager. Two others from the Niño lab--staff research associate Charley Nye, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility, and staffer Christine Torres--assisted with the pollinator education programs.
"It takes a village as they say," Mather said.
That it does.

When you're a little kid and there's a huge bee towering over you, what do you do?
You do what comes naturally.
Kids reacted differently toward the adults who donned the California Master Beekeeper Program's queen bee costume at the third annual California Honey Bee Festival last Saturday in downtown Woodland.
Some looked at Ms. Queen Bee, quite quizzically. What's that?
Others gave her the high five, a smile, a giggle, or a hug as their parents moved in closer to take photos.
But one little boy clutching a stuffed toy pink pig did three things. First he offered an outstretched hand for a high five. Then he introduced his pink pig to Ms. Queen Bee. After the proper introductions, he asked if she would remove her head so he could see her face.
Ms. Queen Bee obliged, much to his delight.
The sign in front of the California Master Beekeeper Program (CAMPB), which is directed by Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, succinctly explained what the program is all about: "Educating stewards and ambassadors for honey bees and beekeeping."
Master Beekeeper Wendy Mather, program manager of CAMPB, and several others staffed the booth, while research associate Bernardo of the Niño lab opened hives inside a screened tent to show visitors what a colony looks like. Bernardo, who serves as the educational supervisor for CAMPB, introduced the crowd to the queen bee, worker bees and drones.
The California Honey Festival, sponsored by the City of Woodland and the UC Davis Honey and Pollination Center, included a cooking stage, a UC Davis educational stage, a kids' zone, a refreshment zone, and live entertainment.
UC Davis was well represented. Among the UC Davis attractions: the Honey and Pollinator Center offered free honey tasting; the Bohart Museum of Entomology displayed both live insects and specimens; the UC Davis Häagen-Dazs Honey Bee Haven provided pollinator gardening information; the UC Davis Graduate Student Association offered t-shirts; and the UC Davis Stores offered a selection of beekeeping and bee books, including "The Honey Bee Hobbyist: The Care and Keeping of Bees" by emeritus professor and retired bee wrangler Norm Gary.
More than 30,000 people attend the festival every year. Its mission: to promote honey, honey bees and their products, and beekeeping. Through lectures and demonstrations, the crowd can learn about bees and how to keep them healthy. Issues facing the bees include pests, pesticides, diseases, malnutrition, and climate changes.
And sometimes understanding honey bees all begins when a little kid can engage with a smiling, costumed queen bee--and she obligingly removes her head!
You'll see scores of honey varietals at the third annual California Honey Festival on Saturday, May 4.
And you can sample the honey, ask questions, and purchase it--the soul of a field of flowers.
The free event, sponsored by the City of Woodland and the UC Davis Honey and Pollination Center, will take place from 10 a.m. to 5 p.m., in downtown Woodland. Last year's festival drew 30,000 people and some 16 California honey companies.
Amina Harris, director of the Honey and Pollination Center, says the festival will include a cooking stage, a UC Davis educational stage, a kids' zone, a beer and mead pavilion and live entertainment.
Among the featured attractions will be a screened bee tent, where festival-goers can see beekeeper Bernardo Niño, staff research associate III in the Elina Niño lab in the UC Davis Department of Entomology and Nematology, open the hive and point out the queen, worker bees and drones. Bernardo is the educational supervisor of the California Master Beekeeper Program, directed by Extension apiculturist Elina Niño and operated by the Niño lab.
"Bernardo will be taking the girls through their paces three times during the day," Harris quipping, referring to the worker bees.
The California Master Beekeepers will be staffing a table throughout the all-day event. The UC Davis Häagen-Dazs Honey Bee Haven will feature a pollinator garden installation highlighting what and how to plant for pollinators, along with displays about common bees found in gardens, said Christine Casey, academic program management officer and manager of the half-acre garden, located on Bee Biology Road. She also will be speaking on bee gardening at 2:45 p.m. on the UC Davis Educational Stage. California Master Beekeepers will be teaching on the educational platforms at the festival.
Kitty Bolte from the Xerces Society of Invertebrate Conservation, one of the speakers, will welcome Woodand as a "Bee City" in the opening address on the UC Davis Educational Stage at 10:15 a.m. Plans also call for UC Davis to be named "Bee University" on Saturday, Harris said. "Rachel Davis, director of the Gateway Gardens, Arboretum has been spearheading this designation."
The UC Davis area, located in the Woodland Opera House Plaza, in the middle of the festival activities, will be abuzz with new additions, Harris said. Newcomers to the festival include the World Food Center Plant Breeders and UC Davis entomology students. (See schedule)
The Pollinator Posse of the Bay Area, headed by Tora Rocha and Terry Smith, will be on hand to explain the importance of pollinators and what everyone can do to help them.
Live entertainment will include Jayson Angove, Jessica Malone, Big Sticky Mess, Bocado Rio, Case Lipka, David Jacobin, Katgruvs, accordionist Jared Johnson, The City of Trees Brass Band and Double X Brass Band. Other live entertainment includes Space Walker and the Hand Stand Nation.
The festival, launched in 2017, aims to cultivate an interest in beekeeping, and to educate the public in support of bees and their keepers, according to Amina Harris, director of the UC Davis Honey and Pollination Center.
