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.

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.
Capsule information:
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.

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. Or, you can contact President Mussen at ecmussen@ucdavis.edu for more information.

Brandi will deliver his presentation on "Beekeeping in California: An Overview of Colony Management," covering the seasonal management of bees and their population cycle, at 10:30 a.m., Wednesday, Sept. 5 in the Activities and Recreation Center (ARC). He will discuss both managed and non-managed colonies.
Brandi, involved in bee industry activities over the past 40 years, chaired the National Honey Board for three years, and served 37 years on the California State Beekeepers' Association Board of Directors, including a year as president in 2016-17. He and his son currently manage about 2000 colonies in Central California.
Brandi, who holds a bachelor of science degree in ag business from California Polytechnic Institute, San Luis Obispo, in 1974, is heavily involved with bees. Among his many activities, he chaired the California Apiary Board from 1992 to 1995; served on the Project Apis m board from 2006 to 2016, and has been a member of the California Almond Board Bee Task Force since 2004 and a member of Carl Hayden Bee Research Center's Industry Liaison Committee since 2002. The USDA research center is located in Tucson.
The Western Apicultural Society (WAS) conference will filled with educational topics, networking, field trips, a silent auction, door prizes and just plain "bee" fun, says honey bee guru and WAS co-founder Eric Mussen, Extension apiculturist emeritus, UC Davis Department of Entomology and Nematology, who is serving his sixth term as president.
The conference is open to all interested persons and registration is underway at http://www.westernapiculturalsociety.org/2017-conference-registration/
WAS, founded at UC Davis, is a non-profit organization that represents mainly small-scale beekeepers in the western portion of North America, from Alaska and the Yukon to California and Arizona. Beekeepers across North America will gather to hear the latest in science and technology pertaining to their industry and how to keep their bees healthy.

You've heard "The 12 Days of Christmas," beginning with a single "partridge in a pear tree" and ending with "12 drummers drumming." In between: two turtle doves, three french hens, four calling birds, five gold rings, six geese-a-laying, seven swans-a-swimming, eight maids-a-milking, nine ladies dancing, 10 lords-a-leaping, and 11 pipers piping.
But have you heard "The 13 Bugs of Christmas?"
Back in 2010, Extension apiculturist Eric Mussen of the UC Davis Department of Entomology (now the UC Davis Department of Entomology and Nematology) and yours truly came up with a song about "The 13 Bugs of Christmas." Presented at the Department of Entomology's holiday party, it drew roaring applause. Then U.S. News featured it when reporter Paul Bedard picked it up.
It's still making the rounds, via social media, and it's also appeared in number of pubications, including a pest control magazine.
"The 13 Bugs of Christmas" is about a psyllid in a pear tree, six lice a'laying, 10 locusts leaping and 11 queen bees piping. Beekeepers know that distinctive sound of a queen bee piping.
"We attempted to keep the wording as close as possible for ‘The 12 Bugs of Christmas' and then we opted to spotlight some new agricultural pests in the next stanza," said Mussen, who retired in June 2014 after 38 years of service.
The song:
On the first day of Christmas, my true love gave to me, a psyllid in a pear tree.
On the second day of Christmas, my true love gave to me, two tortoises beetles and a psyllid in a pear tree
On the third day of Christmas, my true love gave to me, three French flies, two tortoise beetles and a psyllid in a pear tree
On the fourth day of Christmas, my true love gave to me, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the fifth day of Christmas, my true love gave to me five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the sixth day of Christmas, my true love gave to me six lice a'laying, five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the seventh day of Christmas, my true love gave to me seven boatmen swimming, six lice a'laying, five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the eighth day of Christmas, my true love gave to me eight ants a'milking, seven boatmen swimming, six lice a'laying, five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the ninth day of Christmas, my true love gave to me nine mayflies dancing, eight ants a'milking, seven boatmen swimming, six lice a'laying, five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the tenth day of Christmas, my true love gave to me 10 locusts leaping, nine mayflies dancing, eight ants a'milking, seven boatmen swimming, six lice a'laying, five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the 11th day of Christmas, my true love gave to me 11 queen bees piping, 10 locusts leaping, nine mayflies dancing, eight ants a'milking, seven boatmen swimming, six lice a'laying, five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
On the 12th day of Christmas, my true love gave to me 12 deathwatch beetles drumming, 11 queen bees piping, 10 locusts leaping, nine mayflies dancing, eight ants a'milking, seven boatmen swimming, six lice a'laying, five golden bees, four calling cicadas, three French flies, two tortoise beetles and a psyllid in a pear tree
Knowing the agony that Californians experience with the seemingly unending flood of pests, Mussen felt it "bugworthy" to add this verse:
"On the 13th day of Christmas, Californians woke to see:
13 Kaphra beetles,
12 Diaprepes weevils,
11 citrus psyllids,
10 Tropilaelaps clareae,
nine melon fruitflies,
eight Aedes aegypti,
seven ash tree borers,
six spotted-wing Drosophila,
five gypsy moths,
four Japanese beetles,
three imported fire ants,
two brown apple moths,
and a medfly in a pear tree."
Mussen noted that Tropilaelaps clareae is a honey bee mite from Asia, as is the well-known varroa mite (Varroa destructor), which was first detected in the United States (Wisconsin) in 1987 and is now beekeepers' No. 1 problem.
It's unlikely, however, that Tropilaelaps clareae and Varroa destructor will become part of any other Christmas song...but you never know...
