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.
Insects are in. They're not only everywhere in nature (well, almost everywhere!), they've climbed, crawled, jumped, buzzed, fluttered, flew or otherwise positioned themselves on fashions, including the UC Davis Entomology Graduate Student Association (EGSA) t-shirts.
The EGSA, comprised of UC Davis graduate students who study insect systems, is an organization that "works to connect students from across disciplines, inform students of and provide opportunities for academic success, and to serve as a bridge between the students and administration," according to EGSA president Brendon Boudinot, an ant specialist/doctoral student in the Phil Ward lab.
As a year-around fundraising project, they sell t-shirts, which can be viewed and ordered online at https://mkt.com/UCDavisEntGrad/. Jill Oberski, a graduate student in the Phil Ward lab, serves as the t-shirt sales coordinator. She can be reached at email@example.com.
Oberski designed an award-winning onesie, “My Sister Loves Me." It's an adult ant, “loosely based on Ochetellus, a mostly-Australian genus.”
Boudinot's award-winning design is REPRESANT, with illustrations by colleague Eli Sarnat, an alumnus of the Ward lab.
One of the favorite bee t-shirts depicts a honey bee emerging from its iconic hexagonal cells. It's the 2014 winner by then doctoral student Danny Klittich, now a California central coast agronomist.
Another "fave" bee shirt--this one showing a bee barbecuing--is by doctoral student and nematologist Corwin Parker, who studies with Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. It was one of the 2018 winners. (See the three winners on this site.)
EGSA is heading for the Entomological Society of America annual meeting in November. In addition to their participation, the graduate students will be selling shirts at the meeting, appropriately themed "Sharing Insects Globally." It's set for Nov. 11-14 in Vancouver, B.C. The EGSA also sells its t-shirts at other events, including at Briggs Hall during the annual UC Davis Picnic Day.
Insects rock. But some climb, crawl, jump, flutter, buzz, fly or otherwise position themselves on EGSA t-shirts.
Add an innovative project involving insects.
Add three talented instructors: Diane Ullman, professor of entomology, UC Davis Department of Entomology and Nematology, and lecturers Gale Okumura and Morissa Rubin of the UC Davis Department of Design
Result: an art exhibition, “The World of Insects: Paper, Tile, Branding and Packaging.” to take place from 6 to 8 p.m., Wednesday, June 6 in the Environmental Horticulture courtyard, located near Walter A. Buehler Alumni and Visitors Center on Alumni Drive. The event is free and open to the public.
The students will display their branding and packaging of their product for edible insects, said Okumura. "The design students were to create a pattern from the assigned insect, as well as design a logo for their branding, which was then applied to their packaging and business system," she said. "The packaging had be appealing to the consumer and in some sense, change behavior of the audience to buy edible insects by having appealing graphics."
Rubin said the silkscreen prints "focus on illustrations of the insect and its key features (entomology students) or graphic patterns derived from significant markings or features of the insect. Additionally design students have developed an insect related product and its entire graphic identity."
Bottom line: Prepare to enter an amazing world you may not have seen before--the incredible world of insects, coupled with innovative marketing and designs.
And maybe, just maybe, you'll add crickets to your diet?
If you haven't already?
If you attended the 2017 Entomological Society of America (ESA) meeting, held recently in Denver, you probably recognized a familiar face and his research.
This is the third year he has won first-place honors in the President's Prize competition, an opportunity for graduate students to present their research.
Boudinot, who studies classification and evolution of morphology, delivered a 10-minute oral presentation in the Systematics, Evolution and Biodiversity Section on "The Protopodal Theory of Genitalic Evolution in the Hexapoda (Arthropoda: Mandibulata: Pancrustacea)."
Judges evaluate the oral presentations on scientific content (50 percent) and presentation (50 percent). For scientific content, judges score them on introduction and background with pertinent literature cited; objectives clearly stated and concise; materials and methods (study design) clear and concise; results and discussion clear, concise and accurate; and significance of results to field of study. Judges evaluation the presentation on organization, slides and delivery.
For his work, he received a one-year free membership in ESA, a $75 cash prize, and a certificate.
Boudinot's previous President's Prizes were for presentations on the male genitalia of ants, and for providing the first male-based identification material for the ant genera of the New World.
"I study ants because they are a unique evolutionary radiation of wingless, social wasps; through the study of their genetic and morphological diversity, we are better able to understand the ecological and biogeographic components of the process of speciation," Boudinot said today. "I came to study ants through several years of work I did as an undergraduate sorting and identifying ants from thousands of leaf litter samples collected in Central America by the Leaf Litter Arthropods of MesoAmerica project, which I was involved in (see photo of him in Honduras during 2010, as well as a little blurb from the year before he joined UC Davis graduate program)."
Boudinot traces his initial interest in the taxonomic and morphological diversity of ants through direct observational experience. Now, as a member of the Ward Lab, he continues his work, which encompasses three components:
- the diversity and classification of male ants in the New World
- a reclassification of the Formicidae based on phylogenetic analyses combining fossils with living taxa, and
- a study of the morphological evolution of the abdomen of insects, borne out of work done in projects (1) and (2).
Boudinot completed his undergraduate work at the Evergreen State College, Olympia, Wash., and spent a year working as a research technician at the University of Utah before starting his graduate work in 2014 with advisor Phil Ward. He focuses his research on evolution and ecology, approached from the perspective of systematics. “I integrate several lines of inquiry to answer historical evolutionary questions, including morphological and molecular phylogenetics, paleontology, and traditional comparative morphology,” Boudinot related. “I specialize on the skeletomusculature system of the male genitalia of the Hexapoda and the classification of the Formicoidea.”
Ants are highly diverse, with more than 13,000 known species, Boudinot says. "They are, however, but one stitch in the diversity of all insects, and we are entering a new era for the study of morphology in the 21st century."
The genitalia of male insects are fascinating, he said. "Both male and female insect genitalia are derived from the appendages of a pair of abdominal segments. Evidence from the skeletomusculature indicates that these structures are really legs of a crustacean ancestor that have been modified for numerous reproductive tasks--from copulation and insemination, to singing and silk-spinning."
When he's not studying ants, you can find Brendon Boudinot serving as president of the Entomology Graduate Student Association (EGSA), his second term at the helm. In this capacity, he functions as student liaison to the faculty, and as chair or co-chair of several committees, both for departmental and graduate student events (including the Entomology Seminar Series, Retreat Committee, annual Graduate Student Recruitment Day, Picnic Day, and various graduate student social events).
UC Davis doctoral candidate Sarah Silverman of the James R. Carey lab joined Boudinot in the winners' circle at the ESA meeting. She won a second place award in the President's Prize competition, delivering a 10-minute oral presentation in the Diptera-Mosquitoes category of the Medical, Urban, and Veterinary Entomology Section, on “Population as Cohort: Interpreting the Mortality Patterns of Wild-Caught Adult Mosquitoes of Unknown Ages.”
Her work at UC Davis is in the field of insect demography. “I specifically study insect lifespan in the wild," she said, "as well as the the age-structure of insect populations in the wild using an innovative methodological approach: the capture of live-insects in the wild which are then maintained and observed in the lab until death." Silverman completed her bachelor's degree in environmental science at McGill University in Montreal. For her undergraduate thesis, she studied the phenology of wild Osmia bees./span>
Extra, extra, read all about it!
This "extra" has nothing to do with a special edition of a newspaper.
This "extra" deals with something that may puzzle you.
This "extra" refers to the passionflower vine (Passiflora), the host plant of the Gulf Fritillary butterfly (Agraulis vanillae).
About this time of year, the Gulf Frit caterpillars have probably skeletonized your passionflower vine. It's the Halloween poster child of the plant world.
But why, then, are honey bees foraging on a flowerless Passiflora? Their activity has nothing to do with pollination. They're foraging on the leaves and stems. And they're not seeking water.
Extension apiculturist (emeritus) Eric Mussen, UC Davis Department of Entomology and Nematology, answered that question with three little words: "Extra-floral nectary."
It's a subject unfamiliar to many non-botanists and non-biologists.
Wikipedia describes it this way: "Nectar is a sugar-rich liquid produced by plants in glands called nectaries, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide antiherbivore protection."
Lenore Durkee of Grinnell (Iowa) College wrote a scientific paper, "The Floral and Extra-Floral Nectaries of Passiflora," published in the October 1982 edition of the American Journal of Botany, that answers the question and explains the phenomenon.
She defined extra-floral nectaries as "glands that secrete primarily sugars and are found on the vegetative portions of many species of plants."
In her research, Durkee studied the extra-floral nectaries of nine species of Passiflora with light and electron microscopy prior to and during secretion. In her abstract, meant for botanists, she wrote: "There is no evidence of ER or Golfi participation in the secretion of nectar. The vascular tissue supplying the nectary is characterized by companion and pholem parenchyma cells which are usually larger than the sieve elements, a configuration similar to that found in leaf minor veins. In the petiolar nectaries, large masses of membrane-bound protein are commonly found in these cells. This protein is absent in laminar nectaries."
That's probably TMI (too much information) unless you're a botanist.
No worries. The bonus is this: the next time someone asks you why honey bees are foraging on the leaves and stems of your Passiflora (don't you hear that all the time?), you can answer "Extra Flora Nectaries" or "EFN." You can explain that flowers produce nectar but extra-floral nectaries are just nectar-producing glands physically apart from the flower. And, you could add that EFN occurs in more than 2000 plant species in more than 64 families, according to scientists at University of Florida Extension.
Ants like EFN, too.
So do a lot of other insects, including those hungry Gulf Fritillary caterpillars that eat everything in sight...and out of sight...
