Extension apiculturist Elina Lastro Niño of the University of California, Davis, and staff research associate Bernardo Niño are planning three classes this fall and one deals specifically with “Varroa Mite Management Strategies.” The all-day short course starts at 9 a.m. and ends at 4:30 p.m. on Friday, Sept. 22 in the Harry H. Laidlaw Jr. Honey Bee Research Facility, 1 Bee Biology Road, west of the UC Davis central campus.
Current beekeeping challenges call for all beekeepers to have a solid understanding of varroa mite biology and management approaches, the husband-wife Niño team said. “We will dive deeper into understanding varroa biology and will devote the majority of the time to discussing pros and cons of various means to monitor mitigate and manage this crucial honey bee pest.”
The course modules will cover varroa biology, effect of varroa on honey bee colonies, non-chemical management, and chemical options. The practical modules will cover mite monitoring, treatment applications, data/record keeping and inspection of colonies for varroa.
The varroa course is limited to 25 participants, who are asked to bring their bee suit/veil if they own one. The $175 registration fee covers the cost of course materials, lunch and refreshments. Registration is underway at https:registration.ucdavis.edu/Item/Details/342. The last day to register is Wednesday, Sept. 20. The blood-sucking varroa mite, which can also transmit diseases, crippling and decimating a hive, is considered a beekeeper's No. 1 enemy.
Bernardo will speak on beehive iterations on Thursday afternoon, Sept. 7 during a conference tour of the Laidlaw facility from 1 to 4. This is part of several education stations planned at the facility and the nearby bee garden, the Häagen-Dazs Honey Bee Haven, both operated by the UC Davis Department of Entomology and Nematology. There's still time to register for the Western Apicultural Society conference.
Then in October, the Niños will teach two more classes at the Laidlaw facility as part of their fall schedule: “Planning Ahead for Your First Hives” is on Saturday, Oct. 7; and “Queen Rearing Basics” is on Friday, Oct. 20. Both are one-day short courses set from 9 a.m. to 5 p.m. in the Laidlaw facility.
Planning Ahead for Your First Hive, Saturday, Oct. 7, 9 a.m. to 4:30 p.m.: Participants will learn about and practice many aspects of what is necessary to get the colony started and keep it healthy and thriving. This short course will include lectures and hands-on exercises. “This course is perfect for those who have little or no beekeeping experience and would like to obtain more knowledge and practical skills to move on to the next step of owning and caring for their own honey bee colonies,” the Niños said. At the end of the course participants will be knowledgeable about installing honey bee packages, monitoring their own colonies and possible challenges with maintaining a healthy colony.
Lecture modules will cover honey bee biology, beekeeping equipment, how to start your colony and maladies of the hive. Practical modules will cover how to build a hive, how to install a package, how to insect your hive and how to monitor for varroa mites.
The course is limited to 25 participants; participants are asked to bring their bee suit or veil if they own one. The $95 registration fee covers the cost of course materials (including a hive tool), lunch and refreshments. Registration is underway at https://registration.ucdavis.edu/Item/Details/314. The last day to register is Friday, Oct. 6.
Queen-Rearing Basics, Friday, Oct. 20, 9 a.m. to 4:30 p.m.. Participants will have an opportunity to learn about the theory behind the queen rearing strategies and topics from basic queen biology to basics of breeding honey bees. “This course is perfect for those who want to learn more about the most important individual in their colonies or have been thinking about rearing the own queens, but might not feel ready to do hands-on exercise," the Niños said.
Topics covered will include honey bee queen biology, ideal rearing conditions, various queen rearing techniques, mating new queens, installing new queens and basic breeding principles. The course is limited to 25 participants who have basic beekeeping experience. The $125 registration fee covers the cost of breakfast, lunch and refreshments. Registration is underway at https://registration.ucdavis.edu/Item/Details/341. The last day to register is Wednesday, Oct. 18.
About the Niño Team: Elina Niño holds a doctorate in entomology from Pennsylvania State University and Bernardo Niño holds a master's degree in entomology from North Carolina State University.
Through her extension activities, Elina works to support beekeepers and the beekeeping industry. Her lab offers a variety of beekeeping courses and educational opportunities for beekeepers, future beekeepers, other agricultural professionals and the public. Most recently, her lab has implemented the first ever California Master Beekeeper Program. 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.
Bernardo, whose master's degree dealt with the population and genetic colony structure of the Eastern subterranean termite, switched to honey bees eight years ago. He now keeps “more than 130 colonies “happily buzzing to accommodate the needs of all the researchers in the lab,” and leads projects on varroa control and honey bee health. He has also developed a number of educational programs for diverse audiences and for the past seven years he has been involved with organizing and running queen rearing workshops and serving as the program supervisor of the California Master Beekeeper Program.

"Him" is Vernard Lewis, who terminated termites, bugged bed bugs, and controlled cockroaches.
As Pamela Kan Rice, assistant director of News and Information Outreach, University of California Division of Agriculture and Natural Resources (UC ANR) wrote in her wonderful feature story this week on his retirement:
"He built a villa for termites, delighted school children with giant cockroaches, did “time” at San Quentin State Prison, traveled the world looking at insects and, in 2016, Vernard Lewis was inducted into the Pest Management Professionals' Hall of Fame. On July 1, UC Berkeley's first African American entomologist retired from a 35-year career as an urban entomologist, the last 26 years as a UC Cooperative Extension specialist."
We asked Lynn Kimsey, director of the Bohart Museum of Entomology and UC Davis professor of entomology, and integrated pest management specialist Frank Zalom, UC Davis distinguished professor of entomology and a past president of the 7000-member Entomological Society of America (ESA), for their comments:
"Vernard was The Expert for anything termite in California," Kimsey said. "He was the best; knowledgeable, personable and engaged. I'm really annoyed that he retired."
Can you imagine anyone building a home, Villa Termiti, just for termites? Or, rather, to do research?
Wrote Pam Kan-Rice:
"In the early 1990s, the UC Cooperative Extension specialist needed a place to test drywood termite detection and control methods. The College of Natural Resources wasn't keen on infesting a building with destructive pests near UC Berkeley's historic buildings, but ultimately allowed Lewis to construct the Villa Termiti in Richmond, about six miles north of campus."
"Villa Termiti has since hosted ants, subterranean termites, wood-boring beetles, and bed bugs for subsequent research projects."
Lewis, born in Minnesota and the oldest of 10 children, gleefully recalled his fascination with bugs when he moved from Minnesota to Fresno to live with his grandparents for six years. “California has a lot more bugs because Minnesota is frozen six months out of the year,” he said wryly. “During recess, while other kids were kicking balls, I was catching grasshoppers and feeding them to harvester ants.”
Lewis was also known for mentoring young scientists at UC Berkeley and stimulating children's interest in science. He joined the Oakland Unified School District's City Bugs project to educate K-12 school teachers and students about insects, life sciences and biodiversity.
He liked to bring live props and engage his audience. He recalled the time in 1993 when he brought a Madagascar hissing cockroach to show to 300 students at Claremont Middle School, Oakland. You guessed it. The center of attention escaped and both the cockroach and the kids ran for cover. (Well, they ought to visit the Madagascar hissing cockroaches in the Bohart Museum of Entomology. The roaches are part of the insect museum's live "petting zoo.")
Vernard Lewis led a fascinating and productive life. Be sure to read Kan-Rice's entire piece on Vernard Lewis on the UC ANR blog.
You'll note that:
- He showed his can-do attitude with: “My high school counselor said I wasn't bright enough to go to college. I took offense to that,” said Lewis, recalling his high scores on IQ tests administered in the 1950s and 1960s. “I asked him what was the best university in the country. He said, ‘UC Berkeley,' so I decided to go there.”
- He went on to receive three degrees from UC Berkeley: his bachelor of science degree in agricultural sciences in 1975; his master's degree in entomology in 1979; and his doctorate in entomology in 1989.
- He was fondly known as "Killer" at San Quentin Prison because as head of vector control (contract work), he exterminated bed bugs and cockroaches there from 1986 through 1988.
- The ESA featured him in its book “Memoirs of Black Entomologists,” published to spotlight African-American entomologists and to encourage black students to pursue careers in the life sciences.
Bottom line: UC ANR has lost a great scientist, researcher, collaborator, colleague and friend to retirement. Lynn Kimsey is still annoyed that he retired, but the termites, bedbugs and cockroaches--not so much.
No sweat? Or, are you...ahem...sweating the answer?
You can learn more about native bees at a special presentation on Saturday, Sept. 17 in the UC Agriculture and Natural Resources' Hopland Research and Extension Center, Hopland.
"Native Bees in Your Backyard," sponsored by UC ANR, will take place from 10 a.m. to 2 p.m. and will feature entomologist Gordon Frankie, UC Berkeley professor and co-author of California Bees and Blooms: A Guide for Gardeners and Naturalists, and award-winning pollinator garden designer Kate Frey, co-author of The Bee-Friendly Garden (written with co-author Gretchen LeBuhn, professor of biology at San Francisco State University.)
Entomologist/insect photographer Rollin Coville, who captured the spectacular images in California Bees and Blooms, will share his photos.
"The morning will be spent learning about some of the 1,600 native bee species found in California, from the leafcutting bee to the cuckoo bee, the sweat bee to the mining bee!" a spokesperson said. Attendees will learn how to identify them and how to accommodate the needs of the native bees in their own gardeners.
After a locally sourced lunch from Black Dog Farm catering, the participants will carpool to the gardens of Kate Frey, about five miles from the Hopland Research and Extension Center. Her gardens are renowned for their floristic diversity, color and the habitats they provide for wildlife. (See previous Bug Squad blog on Kate Frey.)
California Bees and Blooms is "the bible" of California bee books. A main co-author is Robbin Thorp, distinguished emeritus professor of entomology at UC Davis. Thorp, who received his doctorate in entomology from UC Berkeley, co-teaches The Bee Course every year at the Southwestern Research Station Portal, Ariz., which began today (Aug. 22) and continues through Sept. 1. Rounding out the list of co-authors of California Bees and Blooms is plant expert/curator Barbara Ertter of UC Berkeley.
Registration for "Native Bees in Your Backyard" is now underway at http://hrec.ucanr.edu/?calitem=336669&g=61984. Early bird registration before Sept. 1 is $35. Registration is $40 after this date.

Think ACP. Think HLB. Think ASAP.
ACP spreads the killer huanglongbing (HLB) disease, also called "citrus greening," which is threatening California's citrus industry and residential landscapes. Some 60 percent of California homeowners have at least one citrus tree.
The brown-mottled, aphid-sized pest (Diaphorina citri), a native of Pakistan, was first detected in California in 2008. It earlier wreaked havoc in Florida's citrus industry. Due to HLB and citrus canker, the Florida citrus industry has lost nearly 50 percent of its citrus production in the past 10 years, according to the national Citrus Research Board.
California has more to lose. The Golden State is the No. 1 economic citrus state in the nation, ranking first in the U.S. in terms of economic value and second (after Florida) in terms of production, says the national Citrus Research Board. "California produces approximately 80 percent of the nation's fresh fruit citrus and is the country's main source (80 percent) of fresh-market oranges (Florida grows oranges mainly for juice)."
It's crucial to check for signs of this pest now--right now--because of the new leaf growth (flush). The young, tender leaves are perfect for psyllids. Tell-tale signs of psyllid presence include distorted new leaves and stems, waxy deposits, honeydew and sooty molds.
Checking for psyllids is our first line of defense.
“We encourage home citrus growers and farmers to go out with a magnifying glass or hand lens and look closely at the new growth,” said Beth Grafton-Cardwell, UC Agriculture and Natural Resources (UC ANR) citrus entomologist. “Look for the various stages of the psyllid – small yellow eggs, sesame-seed sized yellow ACP young with curly white tubules, or aphid-like adults that perch with their hind quarters angled up.”
Photos of the Asian citrus psyllids and the life stages are posted on the UC ANR website at http://ucanr.edu/acp. If you find signs of this insect, you're urged to telephone the California Food and Agriculture (CDFA) Exotic Pest Hotline at (800) 491-1899.
Yellow mottling on the leaves may be the first sign your citrus tree is infected with the HLB. Other indications are sour misshapen fruit. If your tree has HLB, that's a death sentence. It will die. You cannot save it.
CDFA officials recently removed a few HLB-infected trees in urban Los Angeles County.
“In California, we are working hard to keep the population of ACP as low as possible until researchers can find a cure for the disease,” Grafton-Cardwell said. “We need the help of citrus farmers and home gardeners.”
A new UC ANR ACP website for citrus growers and homeowners provides help in finding the pest and what to do next. The site, spearheaded by Grafton-Cardwell, includes an interactive map so viewers can locate where the psyllid is established, and areas being targeted.
The website outlines biological control efforts that are underway, and directions for insecticidal control, if it is needed. An online calculator allows farmers and homeowners to determine their potential costs for using insecticides.
Additional measures and precautions are advised:
- When planting new citrus trees, purchase the trees only from reputable nurseries. Do not accept tree cuttings or budwood from neighbors, friends or relatives. HLB can be spread by grafting.
- After pruning or cutting down a citrus tree, dry out the green waste or double bag it to ensure that live psyllids won't hitch a ride to another region and spread HLB from tree to tree.
- Control ants in and near citrus trees with bait stations. Scientists have released natural enemies of ACP in Southern California to help keep the pest in check. However, ants will protect the psyllids from the natural enemies. Ants feed on honeydew.
- Learn more about the Asian citrus psyllid and huanglongbing disease on UC ANR's Statewide Integrated Pest Management website.
- Assist in the control of ACP by supporting CDFA insecticide treatments on your citrus or treating the citrus yourself when psyllids are present.
- Support the removal of HLB-infected trees.
HLB has seriously impacted citrus production in Brazil, India, Asia, the Arabian Peninsula, Africa and now Florida. We don't want California added to that list.
The Extension apiculturist, aka "honey bee guru," officially retired at the end of June after a 38-year academic career. A native of New York, he joined the faculty of the UC Davis Department of Entomology (now the UC Davis Department of Entomology and Nematology) in 1976 after receiving his doctorate in entomology from the University of Minnesota.
He's known not only as the "honey bee guru," but “the pulse of the bee industry" and as "the go-to person" when consumers, scientists, researchers, students, and the news media have questions about honey bees.
Mussen was just named the recipient of the 2013-14 Distinguished Service Award for Outstanding Extension from the UC Agriculture and Natural Resources (UC ANR), a well-deserved honor.
For nearly four decades, he has devoted his research and extension activities toward the improvement of honey bee health and honey bee colony management practices.
His nominators wrote that what sets Dr. Mussen apart from his Extension-specialist peers are these seven attributes:
- His amazing knowledge of bees
- His excellent communication skills in a diverse clientele, including researchers, Extension personnel, legislators, commodity boards, grower organizations, pesticide regulators, students, news media, and beekeeping associations at the national, state and local levels,
- His eagerness to help everyone, no matter the age or stature or expertise, from an inquiring 4-H'er to a beginning beekeeper to a commercial beekeeper
- His ability to translate complicated research in lay terms; he's described as “absolutely the best”
- His willingness—his “just-say-yes” personality---to go above and beyond his job description by presenting multiple talks to every beekeeping association in California, whether it be a weekday, evening or weekend, and his willingness to speak at a wide variety of events, including pollinator workshops, animal biology classes, UC activities and fairs and festivals
- His reputation for being a well-respected, well-liked, honest, and unflappable person with a delightful sense of humor; and
- His valuable research, which includes papers on antiobiotics to control American foulbrood; fungicide toxicity in the almond orchards; the effect of light brown apple moth mating pheromone on honey bees; the effects of high fructose corn syrup and probiotics on bee colonies; and the invasion and behavior of Africanized bees. He is often consulted on colony collapse disorder and bee nutrition.
"Without question, Eric is the No. 1 Extension person dealing with honey bees in the nation, if not the world," said MacArthur Genus Awardee Professor Marla Spivak, Distinguished McKnight University Professor Apiculture/Social Insects at the University of Minnesota. "Research colleagues, beekeepers and the public are all very lucky to have him.”
"I am basically all pro-bee,” Mussen told the American Bee Journal in a two-part feature story published in September of 2011. “Whatever I can do for bees, I do it...It doesn't matter whether there is one hive in the backyard or 15,000 colonies. Bees are bees and the bees' needs are the bees' needs.”
That says it all in a nutshell--or a bee hive.
What next? Eric Mussen will be around the UC Davis campus--his office in Briggs Hall and the bee lab at the Harry H. Laidlaw Jr. Honey Bee Research Facility--to help the new apiculturist, Elina Lastro Niño of Pennsylvania State University get adjusted when she arrives in September. She's known for her expertise on honey bee queen biology, chemical ecology, and genomics. (See news story on the UC Davis Department of Entomology and Nematology website.)
We rather expect that Mussen will continue to be involved with the bees. Maybe he'll write a book on California beekeeping, or update the one he co-authored years ago.
That could very well "bee."
Great job, Eric Mussen! A tip of the veil!
