It's bee-ginning to look a lot like Christmas...
All hail our littlest agricultural worker.
European colonists brought the honey bee (Apis mellifera) to what is now the United States in 1622. Specifically, the bees arrived at the Jamestown colony (Virginia). Native Americans nicknamed the honey bee "the white man's fly."
California would have to wait until 1853 for honey bees to arrive. That's when Texas beekeeper Christopher Shelton, brought his colonies to the San Jose area. A plaque outside the international terminal of the San Jose airport documents their arrival.
The plaque, "First Honeybees in California," reads:
"Here, on the 1939-acre Rancho Potrero de Santa Clara, Christopher A. Shelton in early March 1853 introduced the honey bee to California. In Aspinwall, Panama, Shelton purchased 12 bee hives from a New Yorker and transported them by rail, “bongo,” pack mule and steamship to San Francisco. Only enough bees survived to fill one hive, but these quickly propagated, laying the foundation for California's modern beekeeping industry. California registered Landmark No. 945 plaque placed by the State Department of Parks and Recreation in Cooperation with E. Clampus Vitus, Mountain Charlie Chapter No. 1850, and in honor of San Jose City Historian Clyde Arbuckle, March 6, 1982."
According to atlasobscura.com, "In 1853, Texan Christopher A. Shelton purchased 12 hives of bees from an unknown beekeeper in what is now Colon, Panama. The bees, already transported to Panama from New York, were then sent up to San Francisco and Alviso, the nearest port to San Jose, by steamer. They then continued their journey via train and mule to the 1939-acre Rancho Potrero de Santa Clara where Shelton settled."
"Only enough bees to form one hive survived," the Atlas Obscura post related. "These German black bees (Apis mellifera mellifera) endured the tedious trek and were propagated throughout California and soon the whole of the West Coast. Shelton was not so fortunate and died alongside other prominent South Bay Residents of the time on the infamous Jenny Lind steamship explosion just a month after the receipt of his bees. His three hives—it didn't take long for his original stock to multiply—were sold at auction for $110 each, 22 times the price of a beehive on the East Coast."
Ever seen the inside of a hive? That's where the magic begins. You'll see "The Girls": the queen, nurse maids, nannies, royal attendants, builders, architects, dancers, honey tenders, pollen packers, propolis or "glue" specialists, air conditioning and heating technicians, guards, and undertakers.
And in spring, summer and early fall, you'll see "The Boys," the drones. They have one responsibility: reproduction. The drone mates in mid-air with a virgin queen, and then he dies--"and with a smile on his face," according to the UC Cooperative Extension apiculturist Eric Mussen (1944-2022).
As we celebrate Merry Christmas and the New Year, the bees could use some cele-bee-tion, too.

On Labor Day, a federal holiday, we celebrate the our country's labor movement, our gratitude, and our achievements.
But there is no Labor Day holiday for the worker bee, one of three castes (queen, worker and drone) in a honey bee colony. No Labor Day holiday for the queen, either. In peak season, she will lay from 1000 to 2000 eggs a day. A laborious task, to be sure.
Most will be worker bees, the most needed of the three castes. Worker bees perform such age-related duties as nurse maids, nannies, royal attendants, builders, architects, foragers, dancers, honey tenders, pollen packers, propolis or "glue" specialists, air conditioning and heating technicians, guards, and undertakers. The worker bees (sterile females) run the hive. They're the "you-go" girls, the "you-got-this" girls and the "go-to" girls.
No "atta boys" here. The boys, or drones, have one job to do: mate with a virgin queen (in flight) and then they die. (Or as the late Eric Mussen, UC Extension apiculturist emeritus and a longtime member of the UC Davis Department of Entomology and Nematology faculty, would add "They die with a smile on their face.")
It's a matriarchal society.
But life is short for the foraging worker bees.
"Worker bees live for approximately five to six weeks in the spring and summer," writes author and retired bee scientist and bee wrangler Norman Gary, emeritus professor of entomology at the University of California, Davis, in his book, Honey Bee Hobbyist: The Care and Keeping of Bees.
"Those reared in the fall live for several months--long enough for the colony to survive the winter--and are replaced by young bees in late winter or early spring," says Gary, whose entire apicultural career spans 75 years, from student to retirement 26 years ago. (He still works with bees.)
For the foragers, collecting nectar and pollen can be dangerous. Their searching expeditions and forays can take them four to five miles from their hive. Due to predators (including birds, praying mantids and spiders), pesticides and other issues, many do not return home at night.
They put the "severe" in persevere.
What's not to admire about the honey bee? All hail Apis mellifera, not just on Labor Day, but every day of the year. You go, girls! You got this!

If you haven't been around honey bees much, and can't distinguish the queen from a worker bee (sterile female) or drone (male bee), head over the California Master Beekeeper Program displays at the California Honey Festival on Saturday between 10 a.m. and 5 p.m. in downtown Woodland.
You can watch the bees in a glassed-in observation hive: the three castes, the queen, the workers and the drones.
In peak season, a queen can lay from 1000 to 2000 eggs a day.
It's a matriarchial society and the workers (females) do all the work. The workers' age-related specific duties include nurse maids, nannies, royal attendants, builders, architects, foragers, dancers, honey tenders, pollen packers, propolis or "glue" specialists, air conditioning and heating technicians, guards, and undertakers. The worker bees run the hive.
The California Master Beekeeper Program (CAMPB), directed by Extension apiculturst Elina Lastro Niño of the UC Davis Department of Entomology and Nematoogy, is a "continuous train-the-trainer effort," as its website indicates. "The CAMBP's vision is to train Apprentice, Journey and Master level beekeepers so they can effectively communicate the importance of honey bees and other pollinators within their communities, serve as mentors for other beekeepers, and become the informational conduit between the beekeeping communities throughout the state and UC Cooperative Extension staff."
This is science-based education! This is not Jerry Seinfeld's Bee Movie in which bee misinformation reigns supreme. The scenario: "Barry B. Benson, a bee just graduated from college, is disillusioned at his lone career choice: making honey. On a special trip outside the hive, Barry's life is saved by Vanessa, a florist in New York City. As their relationship blossoms, he discovers humans actually eat honey, and subsequently decides to sue them."
The most egregious error: male bees have nothing to do with making honey or finding flowers or running the hive. Zero. Zilch. Nada.
The drone's sole task is to mate with a virgin queen and then he dies. Any drones left in the hive by the end of the season (late fall, early winter) get kicked out by their sisters. They're just another mouth to feed. The gals don't want to deplete their precious resources.
The California Honey Festival, launched in 2017, is a good place to learn about bees and honey. Admission is free.
Some of the activities:
- The UC Davis Honey and Pollination Center will showcase its honey tasting wheel and offer free honey tasting.
- The California Master Beekeeper Program will staff two educational booths. Visitors can examine a bee observation hive, check out the beekeeping equipment and peer through microscopes. Kids' activities are also planned.
- The Bohart Museum of Entomology of the UC Davis Department of Entomology and Nematolgoy will showcase bee diversity in its specimen drawers. Its live "petting zoo" will include Madagascar hissing cockroaches and stick insects (walking sticks) that folks can hold, said Tabatha Yang, education and outreach coordinator.
- The UC Davis Arboretum and Public Garden will address pollinator needs and gardening.
- The Woodland Public Library will offer a children's reading hour.
- Uncle Jer's Traveling Bee Show will provide educational performances.
- The UC Davis Bookstores booth will contain honey, books, and other gifts for sale.
Amina Harris, director of the UC Davis Honey and Pollination Center, and a co-founder of the California Honey Festival, says 100 vendors will sell everything from food to plants to arts and crafts. Visitors can don a bee costume and get their picture taken in the UC Davis Pollination Park, a collaboration with the UC Davis Arboretum and Public Garden.
An after-party is planned at The Hive, part of Z Specialty Food, Woodland. Harris, the "Queen Bee" of Z Specialty Food, said advance registration is required. Access https://zspecialtyfood.com/event/california-honey-festival-after-party/.

If you're thinking of apiculture, you might be thinking of drones (male bees).
But if you're thinking of agriculture--more specifically sustainable agriculture practices in the 21st century--you ought to be thinking of the importance of unmanned aerial robots.
These drones promise to have a huge impact on 21st century sustainable agriculture.
Indeed, a newly published review paper, “Drones: Innovative Technology for Use in Precision Pest Management,” appearing in the Journal of Economic Entomology, should be required reading. The work of a four-member international team of scientists, including UC Davis entomologist Elvira de Lange, it's one of the first of its kind to summarize scientific literature on the use of agricultural drones for pest management.
De Lange, who assembled the team of authors, says that sustainable agricultural practices in the 21st century should increasingly depend on drones and other innovative technologies.
In advocating the need for more research, the authors say that drones are becoming an important part of precision pest management, from detecting pests to controlling them.
In their review, they emphasize "how sustainable pest management in 21st-century agriculture will depend heavily on novel technologies, and how this trend will lead to a growing need for multi-disciplinary research collaborations between agronomists, ecologists, software programmers, and engineers."
“We propose extensive communication and collaboration between scientists from various disciplines, extension agents, industry professionals, and commercial growers to reach drones' optimal potential to help with pest management and control,” said De Lange, the corresponding author and a postdoctoral fellow in the Christian Nansen lab, UC Davis Department of Entomology and Nematology.
The paper covers the use of drones with remote sensing equipment, to detect pest problems from the air. It calls for the increased use of actuation drones, to provide solutions such as spraying pesticides and releasing biocontrol organisms. “Most literature concerns remote sensing,” said de Lange.
Filho just completed his master's degree on drones and remote sensing in Brazil and is currently a doctoral student. Co-authors, in addition to De Lange, are engineer and drone communication expert Zhaodan Kong, assistant professor, UC Davis Department of Mechanical and Aerospace Engineering; and remote sensing expert Wieke Heldens of the German Aerospace Center, Earth Observation Center, Germany.
“Early outbreak detection and treatment application are inherent to effective pest management, allowing management decisions to be implemented before pests are well-established and crop losses accrue,” the authors wrote in their abstract. “Pest monitoring is time-consuming and may be hampered by lack of reliable or cost-effective sampling techniques. Thus, we argue that an important research challenge associated with enhanced sustainability of pest management in modern agriculture is developing and promoting improved crop monitoring procedures.”
Drones can target pest outbreaks or hot spots in field crops and orchards, such as Colorado potato beetle in potato fields or sugarcane aphid in sorghum, the scientists pointed out. “Pests are unpredictable and not uniformly distributed. Precision agricultural technologies, like the use of drones, can offer important opportunities for integrated pest management (IPM).”
De Lange, noting that drones are increasingly used in agriculture for various purposes, commented: “They are often equipped with remote sensing technology, for yield predictions, evaluation of crop phenology, or characterization of soil properties.”
“There are myriad possibilities for use of drones in pest management,” she said. “Sensing drones, equipped with remote sensing technology, could help detect pest hotspots. Pests are often small and hard to find, so indirect detection, through changes in how plants reflect light, has the potential to find the pest earlier, treat earlier, and keep damage in check.”
“Furthermore, actuation drones, equipped with precision spray rigs or dispensers of biocontrol organisms, could apply localized solutions. Pesticide sprays exactly where needed would reduce the needs to spray an entire field. More efficient distribution of biocontrol organisms would make them a more competitive alternative to pesticides.”
“Remote sensing equipment,” De Lange added, “can also be placed on manned aircraft and satellites. However, drones fly lower, increasing images' spatial resolution, and making clouds less of an issue. They are generally cheaper and can be flown more frequently. Compared to ground-based devices, drones can cover much more ground in a shorter period of time.”
The authors said that drones could also be used to distribute sterile insects and mating disruption, and contribute to pest outbreak prevention, rather than provide only solutions to existing problems.
De Lange, who holds a doctorate in chemical ecology from the University of Neuchâtel, Switzerland, joined the Nansen lab in 2016. Her research interests include plant-insect interactions, integrated pest management, chemical ecology and precision agriculture. She does much of her research on California strawberries.

It's often mistaken for a honey bee. Hey, isn't every floral visitor a bee? No, not by a long shot. One's a fly and one's a bee.
That came to mind last weekend when we saw a large number of honey bees (Apis mellifera) and drone flies (Eristalis tenax) nectaring on Mexican sunflowers (Tithonia). The feeding frenzy brought back all the Internet images of mistaken identities. And the arguments.
That's a bee!
No, it's not. It's a fly.
That's no fly. That's a bee.
It's a fly. Bee-lieve me!
To the untrained eye, they look alike at first glance. They're both insects, they're about the same size, and they're both pollinators.
The drone fly, though, in its immature stage is a rat-tailed maggot that lives in drainage ditches, hangs out around manure piles and sewage, and its idea of a pool party is water that is badly polluted.
Honey bees gather nectar and pollen (and water and propolis) for their colonies. Nectar is their carbohydrate and pollen is their protein.
Drone flies mimic bees in color, size and nectaring behavior. They're actually hover flies, members of the family Syrphidae. Watch them hover over flowers like a helicopter.
Lately, we've been seeing an influx of drone flies in our little pollinator garden. Look closely at their large eyes and stubby antennae and you can easily distinguish them from honey bees. Then notice the "H" on their abdomen. Maybe that's "H" for hello? Or "H" for Halloween? Or, or "H" as in "Hey, I'm not a bee! I just mimic a bee so you'll think I'll sting you."
They're bluffing. Drone flies don't sting.
