UC Davis Continuing and Professional Education and The VINE launch indoor farming classes
A new, comprehensive and advanced learning experience in indoor farming is now available for growers. The VINE, an initiative of University of California Agriculture and Natural Resources (UC ANR), and UC Davis Continuing and Professional Education have opened enrollment for their new Controlled Environment Agriculture Program. Courses begin on July 1.
Controlled environment agriculture is a technology-based method of growing plants that offers precise control over temperature, humidity, light, carbon dioxide and air circulation. CEA can take place in greenhouses, indoor vertical farms or hydroponic farms.
"Unpredictable and extreme weather, pests and growing demand for year-round, local produce are driving growers to move crop production indoors,” said Gabe Youtsey, UC ANR chief innovation officer and co-founder of the VINE.
The CEA Program is designed to impart a deep understanding of both the scientific and practical aspects of indoor farming. The series of four detailed courses, designed to be completed in less than a year, are offered through a flexible online platform. This program is suitable for a wide range of professionals from various sectors including farming operations managers, horticulturists, indoor farming specialists, early-career agriculture professionals, and those in related fields.
"As the agricultural sector evolves, our CEA Program aims to provide the foundational knowledge and practical skills crucial for success in controlled environment agriculture," said Youtsey. "We are preparing participants to effectively manage and innovate within their own agricultural practices."
Participants in the program will receive instruction from international experts in controlled environment agriculture. The curriculum includes an exploration of various business models in CEA, optimal crop selection for different environments, and effective strategies for managing pests and diseases. Additionally, it covers the application of data to enhance growing conditions and profitability, as well as best practices for ensuring product safety and quality.
"Students in this program will gain a deeper understanding of the operational aspects of indoor farming and how they can apply this knowledge to real-world scenarios," said Jennifer Greenier, Ph.D., UC Davis Life Sciences Workforce Development director. "We are committed to providing educational pathways that nurture the skills necessary for advancing career opportunities in agriculture."
The Controlled Environment Agriculture Program is structured around four core courses, each designed to build specific skills and knowledge essential for success in indoor farming:
- Introduction to CEA – Fundamentals of indoor farming, business models, and technological advancements.
- Plant Production in Indoor Farming – Planning and implementing effective operations, understanding plant physiology, and nutrition management.
- Postharvest Processes: Ensuring Crop Quality and Safety in CEA – Food safety, proper storage, distribution, and marketing strategies.
- Data-driven Growing – Developing data management skills and optimizing operations through data analytics.
Individual course fees are $1,000 to $2,000 and the full CEA Program is priced at $6,000. Completely online, the courses are accessible to professionals both domestic and international.

That was the consensus at the Bohart Museum of Entomology open house when attendees tried to locate the queen in the bee observation hive at a table staffed by UC Davis graduate student Richard Martinez of the Elina Lastro Niño lab, Department of Entomology and Nematology.
Martinez purposefully didn't mark the queen.
"Most kids thought the queen was going to be marked--common beekeeping practice--but mine wasn't, so they thought that was unfair," Martinez quipped. "Only one kid was able to find the queen. And it was toward the end of the event. The queen was laying an egg when we found her."
The drones, the males, also drew avid interest.
"After I mentioned the hive has drones, what i referred to as 'the boys'--it helps kids understand their role in the hive--they were fascinated with finding the drones, which they did."
Most kids, however, confused drones for the queen, Martinez said.
Attendees, both adults and youth, delighted in trying on the beekeeper veils and suits, and examining the hive tools and other apiary equipment.
"A lot of the kids asked what bees do inside the hive," Martinez said. "So I went through my list of roles honey bees carry out. One family was super invested in the science behind honey bee research, particularly nutrition, which is what I study."
"It was a pretty fun event," he said.
The queen bee, the largest bee in the colony, has a long, narrow, pointed abdomen, and shorter wings than the worker bee. The worker has a rounded abdomen and wings that extend almost to the end of the abdomen. The drone, stout in body, has what some call "wrap around eyes."
The Bohart Museum open house, held May 19 not only featured honey bees (managed bees) but wild bees. (More images pending)
Martinez, a master's student, studies honey bee health, specializing in nutrition, in the lab of E. L. Niño, associate professor of Cooperative Extension, and a member of the UC Davis Department of Entomology and Nematology faculty.
Martinez recently helped staffed the UC Davis Entomology Graduate Student Association (EGSA) t-shirt booth at Briggs Hall during the 110th annual UC Davis Picnic Day, where he and fellow graduate students wore "Bugbie" shirts. The t-shirt, designed by Marielle Hansel Friedman, a second-year doctoral student in the lab of urban landscape entomologist Emily Meineke, features a rosy maple moth, Dryocampa rubicunda. (EGSA offers a variety of t-shirts on its sales website at https://ucdavisentgrad.square.site/.)
The Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis, houses a global collection of eight million insects, plus a live petting zoo, and a gift shop. Professor Jason Bond, the Evert and Marion Schlinger Endowed Chair of the Department of Entomology and Nematology, and the associate dean, UC Davis College of Agricultural and Environmental Sciences, directs the museum. He also serves as president-elect of the American Arachnological Society.
The next open houses are set for
- Saturday, July 20: "Moth Night at the Museum," 7 p.m. to 11 p.m.
- Saturday, Sept. 28: "Museum ABCs: Arthropods Bohart, and Collecting," 1 to 4:30 p.m.
All open houses are free and family friendly; parking is also free on weekends.
Summer public walk-in hours are on Tuesdays, June 17-Aug. 27 from 9 a.m. to noon, and from 1 to 4 p.m. The museum will be closed to the general public from Sept. 1-22.

Watch out ACP, Persea Mite, Avocado Thrips. Here comes Snake Fly. Not a snake. And not a fly. But a snakefly. It's always fun to be reminded that there are lots of different predators out there, and this one is one of the more voracious. Although because of its slow reproductive cycle, you don't see a lot of them until you start seeing them all over the place. Here's one that came up in a recent text message.

Snakeflies are related to lacewings (order Raphidioptera, rhaphidiids). The adult has a long thorax and can raise the head above the rest of the body which gives it the appearance of a snake ready to strike. Snakeflies are found world-wide, but only in western North America on this continent. Larvae live under the bark of forest, ornamental and fruit trees, including avocado and citrus. They can be helpful predators in fruit orchards. Adults also are predaceous. They would work in concert with other predators for control of Asian Citrus Psyllid and avocado mite and thrips.
Hosts
Larvae feed on wood-boring insects, small insects such as aphids and caterpillars, and various insect eggs, often feeding on insects and mites found in leaf duff. Snakefly adults feed on aphids or other small, weak prey.
Life stages
Egg -The egg is elongated and cylindrical with a small appendage at one end.
Larva - The larva is long and flattened with a black shiny head and prothorax and three pairs of legs. It can be from 1/2 to almost 1 inch (12 to 25 mm) long and is a mottled reddish or grayish color.
Pupa -The pupa is active and not enclosed in a cocoon.
Adult - Snakeflies have four membranous wings which are held roof-like over the body when at rest. The wings, which have many veins, are from 1/4 to 2/3 inch (6 to 17 mm) long. The prothorax is elongated. The female is usually slightly larger than the male and has a long tail-like ovipositor.
Life history
Most species have one generation each year but take 2 to 3 years to complete their life cycle. The larva overwinters in a small depression on the bark surface covered by small pieces of bark. After pupation under the bark, adults emerge and disperse in search of prey. They can be seen in orchards throughout the season.
Adult snakeflies are territorial and carnivorous organisms. They are diurnal and are important predators of aphids and mites. Pollen has also been found in the guts of these organisms and it is unclear whether they require pollen for part of their lifecycle or if it is a favoured food source. The larvae of many raphidiids live immediately below the bark of trees, although others live in crevices in rocks, among leaf litter and in detritus. Here they feed on the eggs and larvae of other arthropods such as mites, springtails, spiders, barklice, sternorrhynchids and auchenorrhynchids. The actual diets of the larvae vary according to their habitats, but both larvae and adults are efficient predators.
What predates/parasitizes snakeflies?
Birds eat them. They predate each other making it difficult to raise in an insectary. And they are parasitized by wasps.

If you're a member of the Hammock lab, you're family.
So it was no surprise--no surprise at all--when Jean-Pierre Delplanque, Vice Provost and Dean of Graduate Studies announced that Hammock is a recipient of a 2024 Graduate Studies Distinguished Graduate and Postdoctoral Mentoring Award.
“Your dedication to mentoring is truly commendable, and this recognition is well-deserved,” he told Hammock in an email.
The annual award recognizes “the vital role mentoring plays in the academic and professional development of graduate students and postdoctoral scholars at UC Davis.” The professor will receive a certificate and a $1,000 education enrichment award.
Hammock, who holds a joint appointment with the Department of Entomology and Nematology and the UC Davis Comprehensive Center, “is an incredible mentor, legendary scientist, highly supportive colleague, and a great friend,” wrote nominator and former Hammock lab member Guodong Zhang, now an assistant professor in the UC Davis Department of Nutrition. “He richly deserves this prestigious award.”
Zhang described the Hammock lab as a “highly multidisciplinary, with members having scientific backgrounds in nutrition, pharmacology, analytical chemistry, cancer, pain, and environmental toxicology. From these extensive interactions within and outside of the research group, I have learned how to conduct scientific collaborations."
“The 3-year postdoc training in the Hammock lab stands out as one of the most rewarding periods in my research journey,” Zhang related. “In my moments of experimental setbacks, Bruce was a constant source of encouragement, guiding me on extracting valuable insights from negative data. Conversely, when experiments yielded positive results, he offered insightful advice and introduced me to other labs at UC Davis, thus broadening the scope of our research projects. Bruce was most excited about the ‘unexpected data' because of his belief that such anomalies often herald new scientific discoveries. And he always encouraged us to perform experiments to disprove his favorite hypotheses, fostering a positive and nurturing research environment.”
In his letter of nomination, Zhang shared comments by four other Hammock lab alumni: Kin Sing Stephen Lee, now an assistant professor, Department of Chemistry, Michigan State University; Yuxin Wang, lead computational biologist and manager of the Stephen Lindemann lab, Purdue University; Weicang Wang, assistant professor, Department of Food Science, Purdue University, and Susanne Mumby, retired assistant dean for postdoctoral affairs at the University of Texas Southwestern Medical Center.

'If Science Is Not Fun, It Shouldn't Be Done!'
We remember when Marlin Rice, a past president of the Entomological Society of America (ESA) chronicled Hammock in a 2020 Legends feature in the ESA's American Entomologist and asked what he looks for in researchers seeking to join his lab. "Curiosity," Hammock replied. "And then there's this: If science is not fun, then it shouldn't be done. And if they enjoy science, then they probably will be successful."
A member of the UC Davis faculty since 1980, Hammock is known for his expertise in chemistry, toxicology, biochemistry, entomology and human health research. His work in enzyme research alone spans more than 50 years. He co-discovered a human enzyme termed Soluble Epoxide Hydrolase (sEH), a key regulatory enzyme involved in the metabolism of fatty acids. The enzyme regulates a new class of natural chemical mediators, which in turn regulates inflammation, blood pressure and pain, and is in human clinical trials to replace opioid analgesics.
As director of the UC Davis Superfund Research Program (funded by the National Institutes of Health's National Institute of Environmental Health Sciences) for nearly four decades, Hammock supported scores of pre- and postdoctoral scholars in interdisciplinary research in five different colleges and graduate groups on campus. campus. He ran a pre- and postdoctoral training grant associated with this program and in addition for 15 years was principal investigator of a NIH training grant in the UC Davis Biotechnology Program.
Hammock is an internationally celebrated scientist. He is a fellow of the National Academy of Inventors, the National Academy of Sciences, the California Academy of Sciences, and ESA. At UC Davis, he received both the Academic Senate's Distinguished Teaching Award and the Faculty Research Lectureship. In 2020, UC Davis Chancellor Gary May awarded him the first-ever Lifetime Achievement Award.
His story, however, begins in Arkansas.
A native of Little Rock, Ark., Bruce received his bachelor's degree in entomology (with minors in zoology and chemistry) magna cum laude from Louisiana State University, Baton Rouge, in 1969. He received his doctorate in entomology-toxicology from UC Berkeley in 1973 with John Casida at UC Berkeley. Hammock served as a public health medical officer with the U.S. Army Academy of Health Science, San Antonio, and as a postdoctoral fellow at the Rockefeller Foundation, Department of Biology, Northwestern University, Evanston, Ill.
In the Army, he served as a medical officer at Fort Sam, Houston, and what he saw--severely burned people in terrible pain--made a lasting impression on him. Today he's deeply involved in his research at UC Davis and the company he founded, EicOsis, in 2011 to alleviate pain in humans and companion animals.
And today, UC Davis distinguished professor Bruce Hammock is a newly announced recipient of a 2024 Graduate Studies Distinguished Graduate and Postdoctoral Mentoring Award. Not only highly commendable, but so well-deserved!
