Boudinot will return to the United States in 2023.
While at UC Davis, Boudinot excelled in academics, leadership, public service activities, professional activities, and 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,” wrote nominator Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. (Update: As of June 14, Boudinot has now published 16 peer-reviewed papers.)
Despite being at an early stage of his academic career, Boudinot had already published several landmark papers on insect systematics, wrote Phil Ward in 2019. "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!"
His exit seminar on March 4 drew a standing room-only crowd in 122 Briggs. His abstract: "It is widely yet loosely agreed that the study of morphology--body form, structure and function--is undergoing a post-genomic revival, cautiously labeled 'phenomics' among active practitioners. I argue that the full reality of phenomics has yet to be realized, and that functional anatomy is the linchpin for the meaningful use of morphological data to understand evolution. In this seminar, I will present two case studies from my dissertation. The first will focus on reproductive anatomy in the context of the major transitions of insects from a marine, crustacean ancestor to the epically abundant diversity of wing-bearing species. The second and ongoing study combines more than 300,000 point-observations of morphology for 431 extinct and extant species with genomic sequence data to reconstruct the sequence of evolution leading to the living ants. I will introduce the audience to several extinct lineages of ants, including a new family of wasp-ant intermediates, and present functional morphological reconstructions of the ancestors of all ants, living and extinct." (Listen to the exit seminar here; access is free.)
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, now known as the Entomology Games, are a lively question-and-answer, college bowl-style competition on entomological facts played between university-sponsored student teams.
Boudinot served as president of the UC Davis Entomology Graduate Student Association from 2006 to 2019, and co-chaired the department's Picnic Day celebration (with forensic entomologist Robert Kimsey) for three years.

NSF has awarded a three-year collaborative research grant to five faculty members at Baker University, Baldwin City, Kansas, and to Lynn Kimsey, director of the Bohart Museum and professor, UC Davis Department of Entomology and Nematology.
All the tardigrades collected by Baker University's faculty and students will find a new home at the Bohart.
“Our part in all this is to act as a repository for all of the specimens collected,” Kimsey said. “We have one of the four largest collections of tardigrades in the world.”
The NSF awarded $256,849 for the project, titled “Cross Departmental Development of an Automated Species Identification System for the Phylum Tardigrada Found on Birds.” Collaborating with Kimsey are Baker University faculty members Scott Kimball, associate professor of biology; Randy Miller, director of research; Robert Schukei, assistant professor of computer science; Mahmoud Al-Kofahi, professor of physics; and Irene Unger, associate professor of biology and director of the Baker Wetlands.
"We thought we had a great project and were thrilled the award committee agreed to fund the full scope of our project," Kimball said in a press release. “Our group will engineer an automated process of preparing microscope slides of tardigrade specimens collected from any of several sources. The second objective is to design a species identification software application that will use computer learning processes to create efficiencies in the identification of specimens. All of this will be used to answer biological questions related to the geographic dispersion of tardigrades, specifically as it relates to the relationship between tardigrades and the birds in their environments that may serve to disperse them across the landscape."
The Bohart Museum's tardigrade current collection includes some 25,000 slide-mounted specimens. In a recent newsletter, Kimsey described the water bear as “one of the most peculiar and indestructible groups of animals known. The microscopic and nearly indestructible tardigrade can survive being heated to 304 degrees Fahrenheit or being chilled for days at -328 F. And, even if it's frozen for 30 years, it can still reproduce." See video on EurekAlert.
They belong to their own phyllum, the Tardigrada (meaning "slow steppers"), and to date there are some 1,500 described species throughout the world. "Tardigrades can survive high pressures of more than 1,200 atmospheres found in the bottom of the abyss," Kimsey says. "They can tolerate 1,000 times more ionizing radiation than other animals."
In appearance, the pudgy water bear seems as cuddly as a teddy bear. It has a barrel-shaped body and eight pudgy legs. The adults usually range from 0.3 to 0.5 mm in length. German zoologist Johann August Ephraim Goeze (1731-1793) first described the critters in 1773, referring to them as "kleiner Wasserbär," or "little water bears."
They're easiest to find on lichens and mosses, Kimsey says, but they can also be found on beaches, in the subtidal zone, freshwater sediments, soil, hot springs and even on barnacles. They've been found "high in the Himalayas to down in the deep sea and even in the interior of Antarctica,” Kimsey said.
They mostly feed on plants or bacteria "but some are predators on smaller tardigrades," Kimsey related. “They use the stylets in their tubular mouth (snout) to pierce "individual plant or bacterial ells or small invertebrates."
Why is the water bear so indestructible? In research published in 2016, geneticist Takekazu Kunieda and his colleagues from the University of Tokyo found that the water bear expresses a tardigrade-specific protein that binds itself to DNA. This acts like a "shield against x-ray radiation, preventing the DNA from snapping apart," according to an article published in Gizmodo.
Said Kimsey: "Tardigrades are awesome. They can dry out completely and then become immortal. In fact, SpaceIL may have left thousands of dried tardigrades on the moon when it crashed (in 2019)." (See news story.)
Plans call for a tardigrade sculpture to grace the entrance to the Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane. The artistic concrete sculpture will be about 4 feet by eight feet, about the size of a cow. A GoFundMe account, set up by the Bohart Museum Society, seeks $5000, and is at https://www.gofundme.com/f/waterbear-sculpture
"Tardigrades are really popular with kids in part because of their representation in the movies Ant-Man and Ant-Man and the Wasp, Star Trek and Family Guy," Kimsey noted.

As of July 8, the commentary, “Inflammation Resolution: a Dual-Pronged Approach to Averting Cytokine Storms in COVID-19?”—the work of a nine-member team of Harvard University and UC Davis researchers—has been downloaded 11,444 times since its publication May 8, 2020. It is online at https://rdcu.be/b33IN.
In comparison, the most downloaded publication in CMR in 2019 received 5,712, statistics show.
Editor-in-Chief and Professor Kenneth Honn, who selected their commentary as the top paper of the month, said it drew more downloads the first week of publication than any other in the journal's history. The work is based on more than 40 years of eicosanoid research from the Hammock lab and more than 40 years of eicosanoid research from the Charles Serhan lab at Harvard Medical School.
“COVID-19 results in excessive inflammation and a cytokine storm caused by the human body's reaction to the SARS-CoV-2 virus,” said lead author Dipak Panigrahy, a Harvard University physician and researcher who collaborates with the Hammock laboratory.
“Controlling the body's inflammatory response to COVID-19 will likely be as important as anti-viral therapies or a vaccine,” Panigraphy said. “Stimulation of inflammation resolutions via pro-resolution lipid mediators that are currently in clinical trials for other inflammatory diseases is a novel approach to turning off the inflammation and preventing the cytokine storm caused by COVID-19.”
The drug is an inhibitor to the soluble epoxide hydrolase (sEH) enzyme, a key regulatory enzyme involved in the metabolism of fatty acids.
Panigraphy and Hammock said they are receiving “tons of calls, media requests and emails” from all over the world, including Norway, Japan, United Kingdom, Germany, France, Mexico and Belgium.
Pioneering research from the Panigrahy and Hammock labs shows that cell debris from surgery, chemotherapy, toxin exposure and other causes lead to production of high levels of pro-inflammatory mediators commonly called cytokines as well as eicosanoids.
“A rapid immune response is critical to controlling this virus,” Panigrahy emphasized.
“We believe it holds promise to combat the inflammation involved with this disease,” said co-author Hammock, a UC Davis distinguished professor who holds a joint appointment with the Department of Entomology and Nematology and the UC Davis Comprehensive Cancer Center. “It hit me in March that what we really need to do is not so much block cytokines as to move upstream to modulate them and resolve them rather than block inflammation.”
“We can increase the concentration of natural pro-resolving mediators termed EETs which act on a biological system to produce other pro-resolution mediators which modulate inflammation and actively resolve the process,” explained Hammock, who founded the Davis-based company EicOsis Human Health LLC, to bring the inhibitor to human clinical trials, which are underway in Texas.
The co-authors include two physician-researchers: Patricia Sime of the Division of Pulmonary and Critical Care Medicine, Virginia Commonwealth University, Richmond, and Irene Cortés-Puch of the Division of Pulmonary, Critical Care and Sleep Medicine, UC Davis Medical Center, and an EicOsis project scientist.
“It is this resolution of inflammation and the subsequent repair that is critical to restore patient health,” said Serhan, whose studies with collaborator Sime show that immune resolution and repair are active processes in the lungs and other tissues. What drives the process, Serhan said, is the production of specific pro-resolving agents (SPMs).
Other co-authors of the paper are Molly Gilligan and Allison Gartung of the Panigrahy lab; Sui Huang of the Institute for Systems Biology, Seattle; and Richard Phipps, independent scholar, Richmond, Va.
National Institutes of Health (NIH) grants, including a National Institute of Environmental Health Science (River Award) to Hammock, helped fund the research. The Panigrahy laboratory is generously supported by the Credit Unions Kids at Heart Team; the C.J. Buckley Pediatric Brain Tumor Fund; and the Joe Andruzzi Foundation.

But if you're Jasmin Ramirez Bonilla, a UC Davis graduate student in entomology, you're seeking to control these agricultural pests through more effective integrated pest management (IPM) strategies.
Jasmin, who plans to complete her master's degree in the spring of 2022, recently presented her thesis proposal, “Advancing Integrated Pest Management Strategies for Cucumber Beetles in California,” to the UC Davis Department of Entomology and Nematology at a Zoom session.
“The beetle of focus for my thesis is the Western striped cucumber beetle, Acalymma trivittatum,” said Jasmin, who studies with major professor and agricultural entomologist Ian Grettenberger, a Cooperative Extension specialist in the UC Davis Department of Entomology and Nematology. “A second species, the Western spotted cucumber beetle, Diabrotica undecimpunctata undecimpunctata--a milder pest but still a pest of melons-- is also part of my project but not the primary subject of my studies.”
Her thesis project consists of three objectives:
- Characterize the non-crop and overwintering habitat
- Clarify short-distance dispersal dynamics after harvest
- Evaluate the utility of the aggregation pheromone, vittatalactone
Both species feed on muskmelons, Cucumis melo. “These include honeydew melon, cantaloupe, crenshaw, and cassava,” she said. “However, Acalymma is the specialist.” Cucumber beetles are pests of plants in the Cucurbitaceae family,which includes melons, gourds, cucumbers, squash and pumpkin.
Of key concern is “the lack of effective IPM tools for the management of cucumber beetles, especially the western striped cucumber beetle,” she said. “There is a critical need to visit this system and revisit the ecology to have a clearer understanding of the non-crop habitat uses and dispersal dynamics to improve and optimize the scouting and monitoring strategies. In addition, one way to monitor and manage insect pests is using semiochemicals such as aggregation pheromones and kairomones—for example, cucurbit blossom volatiles--which are of interest to be combined and studied their efficacy attraction.”
Preliminary data for one of her experiments indicates that the synthetic aggregation pheromone, vittatalactone, attracts the western striped cucumber beetle and the spotted cucumber beetle. “This pheromone was mimicked from airborne volatiles produced by male beetles, Acalymma vittatum, the cousin of the western striped cucumber beetle,” Bonila related. “This pheromone is a potential monitoring tool for managing these beetles and minimize the intensive applications of insecticides on the field.”
What sparked her interest in entomology? When she worked as a field research assistant for six months in 2017 with the UC Cooperative Extension in Woodland and sampled Lygus damage in sunflower fields.
“After this field assistant position, I worked as a junior specialist on an alfalfa weevil project to improve management in alfalfa,” Jasmin related. This was a research grant of the late Larry Godfrey (1956-2017), an Extension entomologist based in the UC Davis Department of Entomology and Nematology. Godfrey, the principal investigator of the grant, worked with co-principal investigator Yolo County Farm Advisor Rachael Long until his death in April.
Long invited Jasmin to apply for the position. “That increased my interest in bugs,” Jasmin said. “There were so many different species and I was constantly collecting plethora of insects in each sample!”
A native of Guatemala, Jasmin moved to the United States at age 15 with her family. “Even though I wasn't born here, I still consider myself Guatemalan,” she related. “My family lives in Los Angeles and I attended Reseda High School in the San Fernando Valley.”
Jasmin, who received her bachelor's degree in earth system science at UC Merced in 2016, worked as a vegetation and ecological restoration intern with the National Park Service before enrolled in the UC Davis graduate program.
But it's the insects—particularly cucumber beetles—that fascinate her.

The Bohart Museum will live-stream the free open house on Facebook. Entomologist Jeff Smith, who curates the 500,000 Lepidoptera (butterflies and moths) collection, will show specimens and answer questions.
Due to the COVID-19 pandemic, this is the Bohart Museum's first-ever Virtual Moth Open House.
“We started holding a moth-themed open house near Mother's Day in May, because people who are enthusiasts for moths are called moth-ers,” said Tabatha Yang, education and outreach coordinator for the Bohart Museum. “We then switched our programming to align with National Moth Week. This year's Moth Week is July 18-26. The annual event is celebrated throughout the world with private and public events.
Bohart Museum officials are preparing videos on black-lighting and how to spread and pin moths.
During the Facebook Live program, viewers can type in their questions on moths.
Smith is expected to answer questions such as:
- What is the largest moth?
- How do butterflies and moths differ?
- What is so unique about moths?
- Why should we be concerned with moth diversity?
Smith received a 2015 Friend of the College Award from the UC Davis College of Agricultural and Environmental Sciences for saving the museum some $160,000 over a 27-year period through his volunteer service.
Kimsey, who has directed the museum since 1989, remembers when Smith joined the museum. “When Jeff was working for Univar Environmental Services, a 35-year career until his retirement in 2013, he would spend some of his vacation days at the museum. Over the years Jeff took over more and more of the curation of the butterfly and moth collection. He took home literally thousands of field pinned specimens and spread their wings at home, bringing them back to the museum perfectly mounted. To date he has spread the wings on more than 200,000 butterflies and moths. This translates into something like 33,000 hours of work!” The numbers have since increased.
“About a decade ago, Jeff began helping us by assembling specimen drawers from kits that we purchased,” Kimsey related. “This substantially lowered our curatorial costs, from $50/drawer to $16/drawer. We use several hundred drawers a year to accommodate donated specimens, research vouchers and specimens resulting from research grants and inventories. More recently, he's been accumulating scrap lumber and making the drawers from scratch at no cost to us. Overall, he has made more than 2000 drawers. Additionally, he makes smaller specimen boxes with the leftover scrap wood, which are used by students taking various field courses in the department. We simply could not curate the collection without his contributions.”
Kimsey praised Smith for completely reorganizing the butterfly and moth collection. “It's no small feat to rearrange this many specimens, housed in roughly one thousand drawers,” she said. “Many thousands of the specimens needed to be identified, and the taxonomy required extensive updating and reorganization.”
The Bohart Museum, located in Room 1124 of the Academic Surge Building, Crocker Lane, UC Davis campus, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum.
Bohart Museum is the home of a “live” petting zoo featuring Madagascar hissing cockroaches, walking sticks and tarantulas, and a gift shop, stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
