The UC team, which swept the national championship last year, just won the regional competition Monday night at the Pacific Branch, Entomological Society of America (PBESA) meeting in San Diego. The Linnaean Games, launched in 1983, are lively, college-bowl style competitions on entomological facts, including questions on insects and entomologists.
The UC team is comprised of UC Davis and UC Berkeley graduate students: captain Ralph Washington Jr., who received his bachelor of science degree at UC Davis and is now a graduate student at UC Berkeley; doctoral candidate Brendon Boudinot of the Phil Ward lab, UC Davis; and graduate student Zach Griebenow of the Phil Ward lab.
At the PBESA meeting, UC Riverside took second, and Washington State University, third.
The UC Team will now defend its championship at the ESA meeting , set Nov. 17-20 in St. Louis, Mo. Both the first and second-place teams from each of the ESA's six branches are eligible to compete.
Question: The Passandridae are a family of beetles. What is unusual about their larvae?
Answer: The larvae are ectoparasitoids of wood-boring insects
Both Boudinot and Washington have received major accolades at the ESA and PBESA meetings. Boudinot, who researches ants, won the 2019 John Henry Comstock Award, the highest graduate student award presented by PBESA. He delivered a presentation on his research at the San Diego meeting. He next will be honored as one of the six Comstock award winners (one from each ESA branch) at the national meeting.
Washington, who at UC Davis studied with major professors Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology, and assistant professor Brian Johnson, won PBESA's 2017 Student Leadership Award.
PBESA encompasses 11 Western states, plus U.S. territories and parts of Canada and Mexico. ESA, the world's largest entomological society, is comprised of 7000 members.
And that's just a small portion of what they do.
And what a difference they're making!
Four UC Davis entomologists won awards from the Pacific Branch, Entomological Society of America (PBESA). They will be honored at the PBESA conference set for March 31-April 2 in San Diego.
Molecular geneticist/physiologist Joanna Chiu won the Physiology, Biochemistry, and Toxicology Award; pollination ecologist Neal Williams, the Plant-Insect Ecosystems Award; doctoral candidate Brendon Boudinot, the John Henry Comstock Graduate Student Award, the highest PBESA graduate student award; and UC Davis doctoral graduate Jessica Gillung, the Early Career Award.
Joanna Chiu is a newly selected Chancellor's Fellow, a five-year prestigious honor given to what Chancellor Gary May calls “prolific scholars, strong teachers, effective mentors and dedicated contributors to campus whose work is novel, unique and cutting-edge, groundbreaking and pathbreaking.”
Chiu investigates the regulation of animal circadian rhythms in her laboratory by using a combination of molecular genetics, biochemical, genomic, proteomic, and metabolomic approaches. Her overall research goal: to dissect the molecular and cellular mechanisms that control the circadian clock in animals, and to investigate how this endogenous timer interacts with the environment and cellular metabolism to drive rhythms of physiology and behavior.
Among the insects she studies: the spotted-wing drosophila, Drosophila suzukii.
"She has published a considerable amount on the spotted-wing drosophila, including its annotated genome, resistance studies, molecular basis of the so-called ‘winter morphs that are found in colder areas, and a molecular diagnostic for quickly providing species identification for all stages of this pest to distinguish it from other common Drosophila species," said emeritus Frank Zalom, UC Davis distinguished professor of entomology and a past president of the 7000-member Entomological Society of America.
"I can honestly say that in my 40 years on the faculty at UC Davis and earlier at the University of Minnesota, I have
never had the opportunity to work with a more collaborative and energetic early career scientist than Dr. Chiu," Zalom said.
Chiu, along with Professor Jay Rosenheim and associate professor Louie Yang of the UC Davis Department of Entomology and Nematology, are co-founders and co-directors of the highly successful, campuswide Research Scholars Program in Insect Biology. She helps students conduct cutting-edge research and provides guidance and advice, even after they have embarked on their own careers. Under her tutelage, many of her students are first authors of publications in prestigious journals.
Neal Williams "is widely known and respected for his excellence in research, extension, outreach, teaching, leadership and mentoring," said nominator Steve Nadler, chair of the Department of Entomology and Nematology. “He is a leading voice in the development of collaborative research on insect ecology. He has organized national and international conferences, leads scores of working groups, and guides reviews of impacts of land use and other global change drivers on insects and the services they provide.”
Williams focuses his research on the ecology and evolution of bees and other pollinator insects and their interactions with flowering plants. His work is particularly timely given concern over the global decline in bees and other pollinators.
Research entomologist James P. Strange of USDA's Bee Biology and Systematics Laboratory at Utah State University, describes Williams as “a valuable resource and prolific scientist in pollination biology and pollinator management. His papers are the result of collaborations with leaders in pollinator ecology, behavior and management and have been cited over 13,000 times during his career. His work has unraveled several questions central to plant-pollinator interactions, especially illuminating our understanding of the impacts of landscape resources on pollinator populations.”
In July, Williams will co-chair the Fourth International Conference on Pollinator Biology, Health and Policy at UC Davis. The four-day conference, themed “Multidimensional Solutions to Current and Future Threats to Pollinator Health,” will highlight recent research advances in the biology and health of pollinators, and link to policy implications.
Williams is also organizing a symposium at the PBESA's San Diego meeting in April on the lifelong contributions of native pollinator specialist, Robbin Thorp, UC Davis distinguished emeritus professor of entomology. Nine scientists influenced by Thorp and his research program will speak.
Brendon Boudinot, who studies with ant specialist/professor Phil Ward, was praised for his academic record, leadership, public service activities, participation in professional activities, and his publications. “A highly respected scientist, teacher and leader with a keen intellect, unbridled enthusiasm, and an incredible penchant for public service, Brendon maintains a 4.00 grade point average; has published 12 outstanding publications on insect systematics (some are landmarks or ground-breaking publications); and engages in exceptional academic, student and professional activities,” Nadler wrote.
Ward said that Boudinot, despite being at an early stage of his academic career, has already published several landmark papers on insect systematics. "This includes a remarkable article, just published in Arthropod Structure & Development, in which Brendon presents a comprehensive theory of genital homologies across all Hexapoda (Boudinot 2018). Based on careful comparative morphological study and conducted within a phylogenetic framework, this paper is a major contribution to the field and is destined to become a “classic." This could have been a decade-long study by any investigator, and yet it is just one chapter of Brendon's thesis!"
Active in PBESA and ESA, Boudinot received multiple “President's Prize” awards for his research presentations at national ESA meetings. He organized the ESA symposium, “Evolutionary and Phylogenetic Morphology,” at the 2018 meeting in Vancouver, B.C. , and delivered a presentation on “Male Ants: Past, Present and Prospects” at the 2016 International Congress of Entomology meeting in Orlando, Fla.
Boudinot served on—and anchored—three of the UC Davis Linnaean Games teams that won national or international ESA championships. The Linnaean Games are a lively question-and-answer, college bowl-style competition on entomological facts played between university-sponsored student teams.
Boudinot has served as president of the UC Davis Entomology Graduate Student Association since 2006, and is active in the campuswide UC Davis Picnic Day; he has co-chaired the department's Picnic Day Committee since 2017.
Jessica Gillung studied for her doctorate with major professor Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology. “Dr. Gillung has made outstanding contributions to entomology, shown commitment to extension or outreach, and excelled in entomological education,” Kimsey wrote in her letter of nomination. “In one word: she is ‘phenomenal.'"
Gillung most recently won the “Best Student Presentation Award” at the ninth annual International Congress of Dipterology, held in Windhoek, Namibia, and the 2018 PBESA Student Leadership Award. Her dissertation was titled: “Systematics and Phylogenomics of Spider Flies (Diptera, Acroceridae).”
Kimsey praised her phenomenal leadership activities, her nearly straight-A academic record (3.91 grade point average), her excellence as an entomologist and teacher, and her incredible publication record. “Note that she has 11 refereed publications on her thesis organisms in very strong journals,” Kimsey wrote. “Most entomologists do not publish nearly that much, even as a postdoctoral scholar or a junior faculty member!”
"Not only is Jessica's research on the cutting edge of the field of phylogenomics but--and this is where leadership comes in--she has taken it upon herself to involve and train other graduate students in the same cutting-edge techniques and theoretical framework," Kimsey said. "She is a dynamo--brilliant and high energy, but also constantly teaching."
A native of Brazil, Gillung speaks four languages fluently: Portuguese, Spanish, English and German. While at UC Davis, Gillung was active in PBESA and ESA, presenting a number of presentations and serving on award-winning Linnaean Games teams. In outreach programs, she reached at least 20,000 people encompassing all events from 2013 to 2018. This included open houses, off-site programs, science presentations, summer camps, classroom activities, UC Davis Picnic Days, agriculture days, and fairs and festivals.
As a postdoctoral researcher at Cornell University in the Bryan Danforth lab, Gillung is researching Apoidea (stinging wasps and bees) phylogenomics, evolution and diversification.

PBESA is one of six branches of the Entomological Society of America (ESA). Founded in 1889, ESA is the world's largest organization serving the professional and scientific needs of entomologists and individuals in related disciplines. It is comprised of more than 7000 members, who are affiliated with educational institutions, health agencies, private industry, and government. Members are researchers, teachers, extension service personnel, administrators, marketing representatives, research technicians, consultants, students, pest management professionals, and hobbyists.
When the 103rd annual meeting of the Pacific Branch of the Entomological Society of America (PBESA) takes place March 31-April 3 in the Hyatt Regency Mission Bay Spa and Marina, San Diego, something very special will happen.
Native pollinator specialist Robbin Thorp, UC Davis distinguished emeritus professor of entomology and a global authority on bumble bees and other native pollinators, will be honored at a special symposium being planned by his colleague, pollination ecologist Neal Williams, professor, UC Davis Department of Entomology and Nematology.
The event is set for Tuesday afternoon, April 2.
“The symposium will include scientific contributions from leaders in the fields of bee ecology, conservation and pollination,” announced Williams. “All are individuals whose work and specialty have been influenced by Robbin and his research program."
The scientists speaking include:
- Neal Williams, UC Davis
- Claire Kremen, University of British Columbia, formerly of UC Berkeley
- James Strange, USDA's Agricultural Research Service
- Heidi Dobson, Whitman College, Walla Walla, Wash.
- Gretchen Lebuhn, San Francisco State University
- Richard Hatfield, Xerces Society for Invertebrate Conservation
- Terry Griswold, USDA's Agricultural Research Service
- Leslie Saul-Gershenz, UC Davis
- Gordon Frankie, UC Berkeley
Thorp, a member of the UC Davis entomology faculty for 30 years, from 1964-1994, achieved emeritus status in 1994 but has continued to engage in research, teaching and public service. In his retirement, he co-authored two books Bumble Bees of North America, an Identification Guide (Princeton University, 2014) and California Bees and Blooms, A Guide for Gardeners and Naturalists (Heyday, 2014).
Thorp, a tireless advocate of pollinator species protection and conservation, is known for his expertise, dedication and passion in protecting native pollinators, especially bumble bees, and for his teaching, research and public service. He is an authority on pollination ecology, ecology and systematics of honey bees, bumble bees, vernal pool bees, conservation of bees, contribution of native bees to crop pollination, and bees of urban gardens and agricultural landscapes. He is active in research projects and open houses at the Bohart Museum of Entomology.
Thorp received his bachelor of science degree in zoology (1955) and his master's degree in zoology (1957) from the University of Michigan, Ann Arbor. He earned his doctorate in entomology in 1964 from UC Berkeley, the same year he joined the UC Davis entomology faculty. He taught courses from 1970 to 2006 on insect classification, general entomology, natural history of insects, field entomology, California insect diversity, and pollination ecology.
Every summer since 2002, Thorp has volunteered his time and expertise to teach at The Bee Course, an annual workshop sponsored by the American Museum of Natural History and held at the Southwestern Research Station, Portal, Ariz. The intensive 9-day workshop, considered the world's premiere native bee biology and taxonomic course, is geared for conservation biologists, pollination ecologists and other biologists who want to gain greater knowledge of the systematics and biology of bees.
An authority on Franklin's bumble bee, Bombus franklini, Thorp has monitored the bumble bee population since 1998 in its narrow distribution range of southern Oregon and northern California. He has not seen it since 2006 and it is feared extinct. In August of 2016 a documentary crew from CNN, headed by John Sutter followed him to a meadow where Thorp last saw Franklin's bumble bee. He wrote about Thorp, then 82, in a piece he called "The Old Man and the Bee," a spinoff of Ernest Hemingway's "The Old Man and the Sea."
Thorp was instrumental in placing the bumble bee on the Red List of Threatened Species of the International Union for Conservation of Nature and Natural Resources (IUCN). Long active in the North America IUCN Bumblebee Specialist Group, Thorp served as its regional co-chair, beginning in 2011.
Thorp was named a fellow of the California Academy of Sciences, San Francisco in 1986; recipient of the Edward A. Dickson Emeriti Professorship of UC Davis in 2010; and recipient of the UC Davis Distinguished Emeritus Award in 2015. Other honors include: member of the UC Davis Bee Team that won PBESA's Team Award in 2013. In addition, he is a past president (2010-2011) of the Davis Botanical Society, and former chair (1992-2011) of the Advisory Committee for the Jepson Prairie Reserve, UC Davis/Natural Reserve System.
Since its inception, Thorp has been involved in the Häagen-Dazs Honey Bee Haven, a half-acre bee garden on Bee Biology Road operated by the UC Davis Department of Entomology and Nematology, installed in 2009. To establish a baseline, he began monitoring the site for bees in 2008. He has since detected more than 80 species of bees.
Thorp has identified thousands and thousands of native bees for scientists, citizen scientists, and the general public, in addition to his other work involving research, teaching, mentoring and public service.
And now he will be honored at a special PBESA symposium. PBESA encompasses 11 Western U.S. states, plus several U.S. territories and parts of Canada and Mexico.
It's an honor well deserved./span>
Her research already has.
She just won the prize for best student presentation at the recent 9th International Congress of Dipterology in Windhoek, Namibia.
Gillung delivered her presentation on “Phylogenetic Relationships of Spider Flies (Acroceridae) – Discordance, Uncertainty and the Perils of Phylogenomics.” Acrocerid adults are floral visitors, and some are specialized pollinators, while the larvae are internal parasitoids of spiders.
Approximately 350 delegates attended the conference; the scientists focus on the Diptera order, which includes houseflies, mosquitoes, and gnats. Gillung was among 40 students presenting their research.
Gillung studies with major professor Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology; mentor Shaun Winterton of the California Department of Food and Agriculture; and collaborator Phil Ward, UC Davis professor of entomology.
UC Davis doctoral students Charlotte Herbert Alberts and Socrates Letana, who both study with Kimsey, also presented their work; Alberts delivered an oral presentation on her research (she studies Asilidae (Assassin flies), and Letana displayed a poster on bot flies.
Presenting the award to Gillung was Professor Thomas Pape of the Natural History Museum of Denmark and chair of the Council for the International Congresses of Dipterology, which organizes the conferences. The next Congress takes place in 2022 in California.
In her abstract, Gillung described spider flies “as a monophyletic group of lower Brachycera currently classified into three subfamilies, 55 genera and ca 530 species.”
“The group has long been considered a rogue taxon and its placement within the Diptera tree of life remains uncertain,” she wrote. “Phylogenetic relationships among lineages of spider flies are by contrast relatively well established, with hypotheses proposed based on molecular data from both Sanger and high-throughput sequencing. Phylogenomic estimation of spider fly relationships yields different topologies, depending on whether data is coded and analyzed as nucleotides or as amino acids. The most significant difference among the two data types is in the monophyly of Panopinae; a morphologically and ecologically recognizable group, that is recovered as monophyletic only in the analyses of nucleotides. This study uses Acroceridae as a system to explore the effects of potential confounding factors in phylogenomic reconstruction. This research takes advantage of modern and powerful statistical approaches, including posterior predictive simulation, to understand the effects of conflict, uncertainty and systematic error in the estimation of evolutionary relationships using the standard phylogenomic toolkit.”
Fast forward to her exit seminar, which she will deliver at 2 p.m., Friday, Dec. 14 in 122 Briggs Hall, located off Kleiber Hall Drive. The title: “Evolution of Fossil and Living Spider Flies (Diptera, Acroceridae): A Tale of Conflict and Uncertainty."
"Parasitoid flies," Gillung wrote in her abstract for her Dec. 14 seminar, "are some of the most remarkable, yet poorly known groups of insects. Represented by over 10,000 species distributed in 21 families, dipteran parasitoids comprise over 100 independent lineages, offering an unparalleled system to understanding the origin, evolution and diversification of the parasitoid life history. My dissertation research unraveled the systematics, evolution and biology of a lineage of dipteran parasitoids specialized in spiders, Acroceridae, commonly known as spider flies. My research resulted in a monograph of fossil spider flies, and a robust hypothesis for the pattern and timing of spider fly evolution based on high throughput sequencing. Through the combination of DNA sequence data obtained via Sanger sequencing with morphological characters, I also estimated their relationships among spider fly genera using an extensive taxon sampling which culminated in a new taxonomic classification for the family.”
Gillung has accepted a postdoctoral position at Cornell University, Ithaca, beginning Jan. 2. She will be working with Bryan Danforth on Apoidea (stinging wasps and bees) phylogenomics, evolution and diversification.
She recently was named the recipient of the prestigious 2018 Student Leadership Award, presented by the Pacific Branch, Entomological Society of America (PBESA), which represents 11 states, seven U.S. territories, and parts of Canada and Mexico.
A native of Brazil, Jessica holds a bachelor's degree in biology from the Federal University of Paraná, Curitiba, Brazil and a master's degree in zoology from the University of São Paulo, Brazil. She speaks four languages fluently: Portuguese, Spanish, English and German.
Which team--the UC Berkeley-UC Davis team or the Washington State University team--would win?
That was the white-knuckle scene at the Linnaean Games competition hosted by the Pacific Branch, Entomological Society of America (PBESA) at its meeting June 10-13 in Reno. The Linnaean Games are a lively question-and-answer, college bowl-style competition on entomological facts played between university-sponsored student teams.
The teams score points by correctly answering random questions. Per the rules, they often try to answer the question before it is completed.
Was the answer Dutch scientist Antonie Philips van Leeuwenhoek? Or not?
After hearing a portion of the question, WSU rapidly--and incorrectly--buzzed in the answer, Leeuwenhoek.
It was actually Jan Swammerdam.
The UC Berkeley-UC Davis Team emerged victorious. The team, captained by Ralph Washington Jr., a graduate student in public policy at UC Berkeley, (formerly a graduate student at UC Davis), included UC Davis doctoral students Brendon Boudinot, Zachary Griebenow and Jill Oberski, all of the Phil Ward lab, and Emily Bick of the Christian Nansen lab.
“Davis vs WSU was the final game of the night,” related Boudinot. “This went into Sudden Death as the teams were tied 90-90 after several UC Davis interrupts reduced their point total. We came back from DOWN to tie at about 15th question, and the sudden death question was specifically selected to be challenging. The key details were ‘Dutch ... microscopist from the 17th century.' WSU buzzed in on the interrupt and stated 'Leeuwenhoek,' which was incorrect, leading to their elimination. The correct answer was Swammerdam."
The complete question: What Dutch scientist, a microscopist, was the first to observe and describe red blood cells? As part of his anatomical research, Swammerdam (1637-1680) "carried out experiments on muscle contraction," according to Wikipedia. "In 1658, he was the first to observe and describe red blood cells. He was one of the first people to use the microscope in dissections, and his techniques remained useful for hundreds of years."
What a close competition! Congratulations to both teams!
PBESA will sponsor the UC Berkeley-UC Davis team at the National Linnaean Games at the Entomological Society of America's annual meeting, set Nov. 11-14, in Vancouver, Canada. Runner-up WSU (my alma mater!) also will compete.
Some of the questions asked at this year's PBESA Linnaean Games, as related by Ralph Washington Jr.:
Question: Name the fungal agent that grows naturally in soils throughout the world and causes white muscardine disease and is commercially packaged as a biological insecticide for the control of termites, whiteflies, and other insect pests?
Answer: Beauveria bassiana
Question: Name the process through which spiders use silk to fly and disperse.
Question: Where are you most likely to encounter a rheophilic insect?
Answer: In moving streams.
UC Davis has done well in the Linnaean Games over the years. It won national championships in both 2015 and 2016; Washington captained both teams. Boudinot was a member of both teams, and Bick, the 2016 team.
