The E. L. Niño Bee Lab, directed by Extension Apiculturist Elina Lastro Niño, University of California, Davis, is now recruiting for its first-ever California Master Beekeeper Program (CAMBP). The deadline to fill out the application form is Wednesday, June 1. Notifications of acceptance will be made by June 15.
Its mission: “To provide science-based education to future stewards and ambassadors for honey bees and beekeeping. The apprentice level is designed to build a solid foundation of basic beekeeping skill and knowledge. When participants achieve this level they may opt to stop or continue on to the more advanced levels: journeyman and master levels.”
“We are extremely excited about launching this program which will bring timely and most current beekeeping and other pollinator information to the stakeholders in California," said coordinator Bernardo Niño. "With the increased interest in beekeeping and need for continued public education we really want to engage those who love bees as much as we do be the true bee ambassadors in their communities."
"And with unique challenges for beekeeping in California--that is, about two million bee colonies end up in California in February each year for almond pollination--it was time to have a California-based program," he said. "We are here to support the bees and the beekeepers and we can't wait to start this new partnership."
A $200 program fee will be due no later than July 1. This cost covers a single exam fee, CAMBP study guide, priority access and program discount to all CAMBP-approved courses at UC Davis.
Individuals must score 75 percent or higher on both a written and field practical examination.
Upon completion, apprentice level beekeepers will at the minimum be able to complete the following practical tasks:
- Light and appropriately operate a smoker (including fire safety crucial for California)
- Identify different casts in the colony
- Confidently open and examine a colony
- Properly manage the colony throughout the year
- Be able to identify and take care of any issues that the colony encounters
- Identify and build/assemble standard hive equipment
- Be able to properly feed colonies if needed
- Prevent colony robbing
- Monitor for pathogens and pests
- Re-queen a colony
They are also expected to engage in community service activities, such as assisting members of youth organizations with bee-related projects; giving a public demonstration on beekeeping at a fair, festival or other similar event; or successfully mentoring a new beekeeper through at least one season.
The program is so far supported by the UC Davis Department of Entomology and Nematology, UC Davis College of Agricultural and Environmental Sciences, UC Davis Honey and Pollination Center, Kaiser Family Foundation, Mann Lake LTD, and Gilroy Beekeepers Association.

So when Yves Le Conte, director of the French National Institute for Agricultural Research, Paris, toured the UC Davis campus prior to his keynote speech at the second annual Bee Symposium, "Bonjour" was not only a greeting, but a very good day.
He toured the Harry H. Laidlaw Jr. Honey Bee Research Facility, the Häagen-Dazs Honey Bee Haven, and the Bohart Museum of Entomology.
Escorted by journalist/master beekeeper Mea McNeil of San Anselmo, he first enjoyed a luncheon catered by McNeil at the Laidlaw facility; toured the Bohart Museum, home of nearly eight million insect specimens; and then visited the honey bee garden, a half-acre bee garden located next to the Laidlaw facility on Bee Biology Road.
McNeil, who profiled him in a bee journal, described him as not only a rigorous scientist, but a warm, caring person. "It was his curiosity about mites that led him to make discoveries about bee pheromones that have substantially changed the understanding of bee behavior," she said. "A good deal of cross pollination took place as he met members of the UC Davis entomology community, and he relished a visit to the Bohart Museum."
Le Conte, known throughout Europe for his varroa mite research and the effects on honey bees, spoke on “Honey Bees That Survive Varroa Mite in the World: What We Can Learn from the French Bees.”
He related that the parasitic varroa mite, "a major pest for beekeepers," arrived in France in 1982, and that untreated colonies died after two or three years. Resistance of the honey bee to the mite is crucial for bees' survival, he said. He and fellow scientists are studying varroa-resistant bees. "We go to beekeepers and say 'Give me a piece of the wing of your queen--we want to study the DNA to select for (varroa) resistance," he said.
In addition to his groundbreaking work in Europe, Le Conte collaborated with bee scientist Gene Robinson at the University of Illinois to isolate the pheromone that helps regulate labor in the honey bee colony. Le Conte has also worked with Mark Winston, Marion Ellis and many others throughout the country. He is a member of the advisory board of the Bee Informed Partnership, which strives to help beekeepers keep healthy and stronger colonies.
The second annual Bee Symposium, held May 7 in the UC Davis Conference Center, and hosted by the Honey and Pollination Center and the UC Davis Department of Entomology and Nematology. Amina Harris, director of the center, and Neal Williams, associate professor in the department and a co-faculty director of the center, emceed the event.

The seminar, sponsored by the UC Davis Department of Entomology and Nematology, will be hosted by assistant professor Joanna Chiu.
Merlin joined Texas A&M's Department of Biology in the fall of 2013 and is a member of the Center for Biological Clocks Research.
The eastern North American monarch butterfly (Danaus plexippus) has emerged as a powerful model system to study animal circadian clocks and their role in an unconventional output, the photoperiod-induced long-distance migration," Merlin says in her abstract.
"Circadian clocks are endogenous 24-hour timekeepers that coordinate nearly all of the animal physiology and behavior to its environment to tune specific activities at the most advantageous time of the day. Monarchs use a circadian clock to navigate to their overwintering sites during their seasonal long-distance migration. The clock time-compensates for the movement of the sun across the sky over the course of the day and regulates the sun compass output in the brain. Circadian clocks could also be used to time the monarch seasonal departure from their breeding grounds, and consequently regulate the genetic/epigenetic program controlling migratory physiology and behavior."
In a news story written by Vimal Patel of the Texas A&M communications office, Merlin is described as zeroing in on "unraveling the mysteries of the migration and the role of internal clocks in the process."
Merlin was quoted as saying: "It's incredible how such a fragile insect can complete a long-range migration so demanding. Every piece of it fascinates me, from how it occurs to why they go precisely where they go."
An excerpt from Patel's piece:
"While she was a postdoctoral researcher at the University of Massachusetts Medical School in the laboratory of Prof. Steven Reppert, Merlin and colleagues showed that the clocks necessary for flight orientation lie in the creatures' antennae -- a departure from the previous conventional wisdom that the brain controlled the mechanism, given that it controls behavioral rhythmicity in virtually every other animal, including humans.
"The conclusion stemmed from Merlin's and her co-workers' collective curiosity concerning a decades-old anecdote. Around 50 years ago, entomologist Fred Urquhart found that Monarchs became disoriented after he clipped off their antennae. Since then, it had remained just a suspicion until the Massachusetts team confirmed it with more rigorous research."
"The team's experiment exploited technology in a way Urquhart, who merely observed the Monarchs in flight, could not at the time. They used a plastic barrel-like device called a Mouritsen-Frost flight simulator in which a butterfly is connected by tungsten wire to an output system that indicates which direction it is flying. The results were clear: The antennae-less Monarchs flew in every which direction, while those with intact antennae flew southwesterly, the migratory direction."
Merlin says she's interested in the role of the circadian clock in the induction of the migration. "Migration begins every year in the fall, when the day lengths change," she says. "The shortened day lengths might be a cue for the monarchs to start their migration. And if we can show this is the case and that the circadian clock is involved, we can now start to understand the genetic program that is allowing the migratory behavior."
A native of France, Merlin received her bachelor's, master's and doctoral degrees majoring in animal biology, invertebrate physiology and insect physiology, respectively, at the University Paris 6 Pierre and Marie Curie in France. She accepted a postdoctoral fellowship at the University of Massachusetts in 2007.

(Editor's Note: An update: The results of the CDFA analysis have been announced. The maternal lineage of the problematic colony in Concord was European. "Therefore, if that queen's daughters were acting in a very Africanized manner, it might have been because she mated with Africanized drones in the area," said Extension apiculturist emeritus Eric Mussen, "or because there are a number of drones from European cantankerous colonies around the area. The paternity tests were not run.")
It's all the buzz.)
For the past several days, journalists have sought out UC Davis experts Extension apiculturist Elina Niño and Extension apiculturist (emeritus) Eric Mussen to weigh in on the recent defensive bee incident in Concord.
The three-day incident began Friday, May 13, and primarily ended on Sunday, when many of the bees were destroyed. What happened: A beekeeper on Hitchcock Road was moving his two hives to make way for landscaping in his yard. He moved the first hive successfully, but the bees in the second hive turned defensive, killing two dogs, attacking a mail carrier, and targeting numerous passersby.
DNA tests are underway to see if the bees are Africanized. “Their behavior is very suggestive that they could be Africanized,” Mussen said.
Niño, who joined the UC Davis Department of Entomology and Nematology in September 2014, replacing Mussen, was interviewed by the Associated Press, San Francisco and Kathy Park of KXTV Channel 10 and Tom Jensen of KCRA Channel 3. More interviews are pending.
Mussen, who completed a 38-year career in 2014 and now serves as emeritus, was quoted in the San Francisco Chronicle and in other news media.
Niño told KCRA "Africanized honey bees tend to be more defensive, they amount a stronger defensive response. First of all, we don't like to call them killer bees. That's definitely not what they're there for. They're not coming at you for no reason."
Mussen told the San Francisco Chronicle that attempts to avoid the bees may have actually made things worse. Waving arms and swatting motions can provoke bees to sting — and then the stings themselves act as markers for other bees to target, he said.
Africanized bees are a hybrid of African honey bees and European/Western honey bees. In the 1950s, Brazilian scientists exported bees from South Africa to improve breeding stock and increase honey production. However the bees escaped quarantine and began mating with European honey bees. Since they they have spread throughout South and Central America and arrived in North America in 1985. Africanized bees expanded into southern California in 1994.
In appearance, Africanized bees and European honey bees look alike and cannot be distinguished except through DNA tests, Niño and Mussen said.
Mussen says that we have three ways to try to differentiate between Africanized honey bees (AHBs) and European honey bees (EHBs):
1. Mitochondrial DNA – The California Department of Food and Agricuture (CDFA) still conducts this type of testing once a year to clear the California Bee Breeders for queen exports into Canada. CDFA also uses this criterion as "the one" for declaring Africanization. However, its value in predicting temperament of the colony population is not particularly reliable.
2. Isozymes - the amino acid composition of certain enzymes differs between the two races
3. Morphometrics - computer matching of current sample specimens to verified AHB and EHB samples using measurements of various anatomical features. Hybrids are problematic.
"That type of bee was found around southern California and as far north as not too far from Angles Camp (Calaveras County)," Mussen mentioned. "Further north, they found only specimens with one or two traits, but not all three. That even occurred just into southern Oregon."
“Yes, EHB colonies can behave in that nasty manner, but I think it is more likely that AHBs are involved,” Mussen says. He recalled that twice in the 1980s, swarms of bees from South America accompanied shipments of raw sugar cane into the C&H sugar refinery in Crockett (Contra Costa County). We know the first one got away. They think they got the second one, but could not find the queen in either case. Since that time, there have been increasing complaints of 'hot' bees from that area, south to Castro Valley (Alameda County).”
Assistant professor Brian Johnson of the UC Davis Department of Entomology and Nematology, is doing research on genetic dispersion of AHBs around the state. He is collecting and freezing samples.
