"In winter, honey bees undergo a transition to a diutinus state, during which time brood rearing declines or stops entirely, and worker bees live for up to 20 weeks," Coit says in her abstract. "The mechanism, causes, and geographic prevalence of this transition are unknown, and can make managing honey bees in certain regions challenging. We hypothesized that the transition to overwintering is regulated by the forager pheromone, ethyl oleate, when forager bees are relegated to the hive for longer periods of time during poor weather conditions. We exposed bees of different ages and tasks to ethyl oleate and measured accepted markers of overwintering. Our findings indicate ethyl oleate may affect the efficiency of metabolism of protein into fat stores, allowing young bees to prepare for suboptimal conditions. Ethyl oleate, when concomitant with other factors such as gradual decline in brood pheromone, pollen dearth, cold temperatures, and photoperiod, may contribute to the transition to overwintering."
Coit, who grew up around Asheville, N.C., holds a bachelor of science degree in biology (2019) from the University of North Carolina (UNC) at Chapel Hill.
She received her master's degree from UC Davis on Sept. 9, and is currently working and living in Vermont. "I work at Sterling College, where I am teaching entomology, ecology, biology, and apiculture in the undergraduate program, as well as developing course materials for the continuing education department in a variety of subjects such as water management, agroecology, pest management, and sustainable agriculture and food systems."
Her biography on the Niño website includes: "She was founder and president of the Carolina Beekeeping Club, whose efforts recently succeeded in making UNC, a Bee Campus USA. She first became interested in honey bees in high school while taking a summer class at Cornell. In college, she began volunteering at the NC State University Honey Bee Research Laboratory to gain more experience with bees. Since then, she has also worked at NC State as a research technician and conducted her own research on pheromone variation of brood and queens among different stocks of bees."
Coit studied abroad at the University of Otago, Dunedin, New Zealand, in 2017, from July to November.
Emily Meineke, assistant professor of urban landscape entomology, UC Davis Department of Entomology and Nematology, coordinates the department's seminars for the 2022-23 academic year. All 11 seminars will take place both person and virtually at 4:10 p.m. on Wednesdays in Room 122 of Briggs Hall except for the Nov. 9th and Dec. 7th seminars, which will be virtual only, she said.

The video guidebook showcases the 480-page textbook, Biodemography: An Introduction to Concepts and Methods (Princeton University Press, 2020), co-authored by Deborah Roach, professor and chair of the University of Virginia's Department of Biology. Carey and Roach define the pioneering field of biodemography as “integrating biology, mathematics and demography.”
The video guidebook, now online on the UC Berkeley Population Sciences website, is unique in that never before has a scientific textbook author produced, scripted and narrated videos that encompass a book's entire content. The playlist includes 175 separate presentations, closed captioned in English and subtitled through YouTube in 300 different languages. The video guidebook covers the contents of his entire biodemography book with video modules on content ranging from life tables, mortality models and reproduction to stable population theory, matrix models and applied demography. He also has several dozen videos on best practices in visualization and presentation strategies.
Carey, a member of the UC Davis Department of Entomology and Nematology faculty since 1980 and a senior scholar with the UC Berkeley Center on the Economics and Demography of Aging (CEDA), opted to create the video playbook because “we believe the contents should be available to anyone interested in any aspect of biodemography regardless of their access to the book or their primary language.”
Carey is a fellow of four professional societies: the Entomological Society of America, the American Association for the Advancement of Science, the California Academy of Sciences, and the Gerontological Society of America. He is former director (2003-13) of a 11-university consortium funded by the National Institute on Aging (NIH/P01) on the evolutionary ecology of lifespan.

The event is free and family friendly. It is the Bohart's first special event of the fall season.
Visitors will learn about the smallest fairy wasps to the "murder hornets"; what role wasps play in plant galls and figs; and how to distinguish a parasitoid from a parasite. Lynn Kimsey, director of the Bohart Museum and a UC Davis distinguished professor of entomology, will discuss the Asian giant hornet, Vespa mandarinia, dubbed by the news media as “the murder hornet." The Entomological Society of America recently established as its official common name, “northern giant hornet.”
A single colony of the Asian giant hornet was found and destroyed Sept. 18, 2019 in Nanaimo, Vancouver Island, Canada, and a single dead hornet was found Dec. 8, 2019 in nearby Blaine, Wash. Since then, it also has been sighted-- and destroyed--in both Canada and Washington state.
Kimsey, an authority on the giant hornet and a two-term past president of the International Society of Hymenopterist, says the insects probably "hitched a ride" in a cargo box shipped from Asia to a North American seaport. The insect is considered the world's largest species of hornet and can reach up to 2 inches in length. A few hornets can destroy a bee colony, decapitating the honey bees, in a matter of hours.
Kimsey and two other wasp experts published “The Diversity of Hornets in the Genus Vespa (Hymenoptera: Vespidae; Vespinae); Their Importance and Interceptions in the United States,” in the journal Insect Systematics and Diversity in May of 2020. (See https://bit.ly/3BVZ34Y)
Lead author Allan Smith-Pardo, U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS), and co-authors James Carpenter of the American Museum of Natural History's Division of Invertebrate Zoology, and Kimsey covered 22 species of hornets, including V. mandarinia.
Fairy wasps, which belong to the family of chalcidoid wasps, are tiny insects that include the world's smallest known insect, with a body length of 0.139mm, and the smallest known flying insect, only 0.15mm. All known fairy wasps are parasitoids of the eggs of other insects.
A family arts-and-crafts activity is also planned at the open house.
The Bohart Museum is the home of a global collection of eight million insect specimens. It also houses a live “petting zoo,” comprised of Madagascar hissing cockroaches, stick insects and tarantulas; and a gift shop with insect-themed items. More information is available on the website at https://bohart.ucdavis.edu or by contacting bmuseum@ucdavis.edu.

UC Davis Chancellor Gary May congratulated the recipients.
In his remarks, Chancellor May told the crowd: "This is truly an exciting time for UC Davis. I hope you heard that we were ranked #2 nationally among public universities in Washington Monthly's 2022 Guide and Rankings. On top of that, UC Davis retained its No. 4 public university ranking in America's Top College List 2022 by Forbes. In some places UC Davis is the top, such as No. 1 for sustainabilty. UC Davis is also ranked No. 1 in the nation for diversity, inclusiveness and internationalization. And, we recently set a university record by attracting more than $1 billion in annual research awards. Fewer than 20 universities in the country can claim this."
"I could go on," the chancellor continued, "but the fact of the matter is that we are doing great work at UC Davis, and each of you are a part of this effort. I know how important your expertise, experience and institutional memory are to advancing the university's success. It's sometimes difficult to appreciate how our individual contributions make a difference in the 'big picture.' But every day, the work of staff are critical to our university projects, our operations and our campus environment."
The chancellor pointed out: "These behind-the-scene efforts are what keep UC Davis humming and in tune with our mission of excellence in teaching, research and public service. They are a big part of what your university and Staff Assembly recognizes and thanks you for today. The individuals and teams we honor this afternoon have gone 'above and beyond' all expectations to make UC Davis a more enjoyable, creative, inclusive and invigorating place to work.
He added: "I am proud of all UC Davis staff, but the individuals and teams we honor this afternoon have gone above and beyond in contributing to the university's success. Thank you so much for your outstanding contributions to UC Davis. Our university is a better place today because of your accomplishments, because of your hard work and because of your inspiring dedication to excellence."
In all, the UC Davis Staff Assembly awarded individual honors in five categories for its Citation of Excellence program: innovation, mentorship, service, supervision, and teaching, as well as a team award and a faculty and staff partnership award. The Staff Assembly also awarded scholarships to campus and UC Davis Health staff and staff dependents.
Jennifer Jackson, chair of the UC Davis Staff Assembly, and Jana Avila, chair of the UC Davis Health Staff Assembly, welcomed the crowd. Jackson serves as the Academic Program analyst in the College of Agricultural and Environmental Sciences, Dean's Office, and works with undergraduate student data for the college. Avila is the Affiliate Network manager.

His seminar, set for 4:10 p.m. in 122 Briggs Hall, will focus on Diabrotica (cornroot worms). It will be both in-person and via Zoom. The Zoom link: https://ucdavis.zoom.us/j/
Host is molecular geneticist and physiologist Joanna Chiu, professor and vice chair of the Department of Entomology and Nematology.
"Although they are largely studied because of their economic significance, agricultural pests can be useful model systems to study fundamental biology," Miller says in his abstract. "The beetle genus Diabrotica ("corn rootworms") includes species with generalist and specialist feeding habits that overlap on a common host plant, maize. This makes the genus an excellent system to study the adaptations of insect herbivores with differing host ranges to a common set of plant defenses. A long-standing area of interest in my lab is the adaptations of generalist and specialist Diabrotica species to the maize defensive compound DIMBOA."
Research in the Miller lab focuses on the population genetics and evolution of herbivorous insects. "We mostly study species that are pests of agriculture," he says on his website. "Key areas of interest include: adaptation by insect pests to the technologies intended to control them, including genetically-modified crops and pesticides; the interactions of specialist and generalist herbivores to plant defenses; dispersal and movement of insects and the genes they carry."
Miller holds a bachelor's degree and a doctorate from the University of Birmingham. His most recent publication:
