"A worker honey bee has how many pairs of wax glands on its abdomen?"
That would be four, answered the UC Davis Entomology Team did at the Entomological Society of America's Virtual Entomology Games, a college-bowl type of competition formerly known as the Linnaean Games.
Doctoral students Jill Oberski, Zachary Griebenow and Hannah Kahl of the UC Davis Department of Entomology and Nematology teamed to compete in Games, a fun and lively event but this year it went virtual due to COVID-19 pandemic precautions.
Oberski and Griebenow are both fourth-year doctoral students in the Phil Ward lab, while Kahl, a member of the Jay Rosenheim lab, is currently a third-year doctoral student who will begin her fourth year in January.
The UC Davis team won its preliminary round and then entered the highly competitive finals, placing 11th. Alabama's Auburn University edged the Boiler Bugs of Purdue to win the championship.
The champions, from Auburn University's Department of Entomology and Plant Pathology, answered 27 of the 40 questions correctly, tying with the Boiler Bugs of Purdue, “but Auburn had the closest answer for the tiebreaker question,” Rominiecki said.
In the Entomology Games, teams of two to four students test their entomological knowledge by answering questions drawn from all disciplines of insect science: behavior and ecology, biological control, entomology in culture, integrated pest management (IPM) and insect/plant interactions, medical and veterinary entomology, biochemistry and toxicology economic entomology, history of entomology, morphology and physiology, and systematics and evolution.
ESA did not record the Games this year, as the event itself “was mostly just a recitation of the questions, without the more lively 'buzzing in' format of the live event,” Rominiecki related.
“All in all, we were pleased with how the Entomology Games went this year, in an entirely new format," he said. "Our organizers worked hard in just a few short months to create a virtual version of the Games, and it was great to have teams from all over the country participating as usual, despite the new circumstances. We look forward to returning to an in-person event in the future, of course, but the 2020 virtual edition will be a memorable one. Congratulations to Auburn on their victory, and kudos to all the teams who participated!”

The tiebreaker question? It dealt with the number of Far Side comics referencing insects. The question: "Gary Larson is known for using insects as a source of humor in his acclaimed comic strip 'The Far Side.' A survey of 4,300 'Far Side' comics revealed that exactly how many contained some sort of entomological reference?" Answer: 359.
Over the last few years, UC Davis teams have won the national championship three times in the fun and lively competitions. (See Bug Squad blog)
"Hopefully, we can be back onstage in person next year," said Oberski.
So begins Marlin Rice, author and a past president of the Entomological Society of America (ESA), in his wonderful and comprehensive piece in the current edition of ESA's American Entomologist about the legendary Bruce Hammock.
His story 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.
The headline says it well: "Bruce D. Hammock: Science Should Be Fun."
Hammock describes his Tom Sawyer-like childhood in Little Rock, where he wandered the woods and collected animals.
Rice asked him: "What was your favorite thing to collect?"
"I just liked interested creatures," Hammock told him. "I had a pet 'coon, pet deer, pet 'possums named Sears and Roebuck. The two 'possums had stolen some hot dogs at a Boy Scout jamboree and were trying to make their escape. This guy was going to kill them, so I took them home."
"I found Willy—his mom had been killed by hunters—in a tree stump and bottle-raised him with an old toothless bulldog, and he would ride around on her back. Raccoons and dogs are natural enemies. If an [unfamiliar] dog would growl at him, Willy would try to kill it, so he was not popular."
Young Tom went on to become an Eagle Scout and graduate from Louisiana State University. "I liked football, but I was not good at it," he recalled. "But I was upset with the football craziness in Arkansas, so I thought I could go to LSU and get away from it, but I ended up living underneath the football stadium."
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.
Of EicOsis, he told Rice: "It's actually three companies: human health, equine health, and companion animal health. The human health goal is moving the drug into the clinic to treat human neuropathic pain. In dogs and cats and horses, it turns out that non-steroidals, like aspirin, are so much more toxic. If you give your dog some non-steroidals, you're saying you want your dog to be pain-free for a year, but you know you're killing it. Some non-steroidals are so toxic to non-primates that there's a real opportunity to get epoxide hydrolase to the clinic."
Excerpts from the article:
- Little did we know: While in Warsaw to attend a scientific meeting, Professor Hammock was arrested in Poland on suspicion of being a spy and spent six hours in jail.
- What does he look for in researchers hoping to join his lab? "Curiosity. 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."
- Why did he leave UC Riverside for UC Davis? "Smog. [But] I absolutely loved Riverside. At the time, it was the largest entomology department in the world. It was just wonderful. And it was in the desert and I loved the desert. And I like rattlesnakes, and there is no shortage of rattlesnakes. They're not very pettable, but they're interesting. I've been bitten a lot of times by non-poisonous snakes. I thought I was fast, but snakes were faster. So I never kept a rattlesnake more than a few hours."
- His parents? His father was a postal worker and his mother sold World Book encyclopedias "and was convinced that if you bought World Book, you would be brilliant."
Indeed, Bruce Hammock's career is incredible--incredibly focused, superlative and kind. But he also has a finely honed sense of humor. Who else would launch an annual water balloon battle? He started it in 1980 on the Briggs Hall lawn, just outside his office. It's now called the Bruce Hammock Lab Water Balloon Battle or "Bruce's Big Balloon Battle at Briggs."
"A few years ago, we had the management officer in biochemistry upset because she thought it was unseemly for the university," Hammock told Rice. "Last year, somebody called the police on us, and the police came, and the guy took off his gun belt and joined us. [Laughs.] That was fun!"
So is science. Or it ought to be.

A year-long project on "Current Techniques in Morphology" was posted online today (Nov. 12).
Doctoral candidate Brendon Boudinot of the Phil Ward lab, UC Davis Department of Entomology and Nematology, edited the special collection of articles for the Entomological Society of America journal, Insect Systematics and Diversity (ISD). The work is publicized on EurekAlert! and the entire project can be accessed free online.
Boudinot co-led the development of the collection with István Mikó, collections manager at the University of New Hampshire Department of Biological Sciences.
For the year-long project. Boudinot and Mikó gathered articles illustrating cutting-edge research techniques in insect morphology and phylogenetics, including videos, interactive 3D images, and augmented reality.
"The increasing availability of advanced technologies, such as micro-computed tomography and confocal laser scanning microscopy, are allowing researchers to generate models of morphology in three and four dimensions based on physical data,” Boudinot wrote in the foreword. “These models not only allow for detailed and quantitative study of anatomical systems and their biomechanical properties, but they also allow end-users to experience the richness of morphology in virtual reality, which is incredible."
Boudinot marvels at the 3D models “which open new pathways of research and which you can manipulate on your computer, and another which can project your model in virtual reality on your phone or tablet.”
Boudinot also wrote an editorial on the future of morphology titled Toward Phylomics in Entomology: Current Systematic and Evolutionary Morphology.
Articles in the collection include:
- A Systematist's Guide to Estimating Bayesian Phylogenies From Morphological Data
- PARAMO: A Pipeline for Reconstructing Ancestral Anatomies Using Ontologies and Stochastic Mapping
- From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
- Jumping and Grasping: Universal Locking Mechanisms in Insect Legs
- Revision of the Highly Specialized Ant Genus Discothyrea (Hymenoptera: Formicidae) in the Afrotropics with X-Ray Microtomography and 3D Cybertaxonomy
- Ready Species One: Exploring the Use of Augmented Reality to Enhance Systematic Biology with a Revision of Fijian Strumigenys (Hymenoptera: Formicidae)
“Morphology, encompassing the study of phenotypic form and function, is one of the ancient branches of human knowledge and is foundational for organismal classification,” Boudinot wrote in his editorial. “Two decades into the current century, the specialized biological knowledge of the history and pattern of evolution has been revolutionized by genome-scale sequencing technologies, and cryptic variation within and among species is quantifiable even with a few genetic markers. The application of statistical phylogenetic models of nucleotide and amino acid substitution to sequence data has enabled revised interpretations of morphological identities—be they population-level generalizations, such as species diagnoses, or the definition and homology of specific anatomical entities—and evolutionary transformation across the tree of life (e.g., insect genitalia, ancestral morphology of Polyneoptera). These models are also being adapted for phylogenetic analysis of morphological data, allowing explicit incorporation of fossil terminals and their stratigraphic information.”
Boudinot coined the word, “Phylomics,” which he said “can be defined as the inference of organismal evolution at the molecular and morphological scale, through the use of genomic and phenomic data (the ‘phenome' being a physical model of the phenotype of an organism, such as seen in the ISD special collection). The idea ultimately is to model the morphology of organisms across the phylogeny, through time, literally depicting ancestors and seeing the transformation from ancestor to descendant across the tree of life.”
UC Davis undergraduate student Ziv Lieberman of the Phil Ward lab (he's a senior majoring in evolution and ecology), and Francisco Hita-Garcia of Okinawa (of the Biodiversity and Biocomplexity Unit and Institute of Science and Technology Graduate University), served as the lead authors of “Revision of the Highly Specialized Ant Genus Discothyrea (Hymenoptera: Formicidae) in the Afrotropics with X-Ray Microtomography and 3D Cybertaxonomy.”
Lieberman and Hita-Garcia and three other co-authors described 15 new species in the genus, which is poorly represented in museum collections. Due to its “cryptic lifestyle, Discothyrea are poorly represented in museum collections and their taxonomy has been severely neglected,” they wrote. “We perform the first comprehensive revision of Discothyrea in the Afrotropical region through a combination of traditional and three-dimensional (3D) cybertaxonomy based on microtomography (micro-CT). Species diagnostics and morphological character evaluations are based on examinations of all physical specimens and virtual analyses of 3D surface models generated from micro-CT data.” These models can be seen for free in their article and online at https://sketchfab.com/arilab/collections/discothyrea.
Additionally, they applied “virtual dissections for detailed examinations of cephalic structures to establish terminology based on homology for the first time in Discothyrea. The complete datasets comprising micro-CT data, 3D surface models and videos, still images of volume renderings, and colored stacked images are available online as cybertype datasets (Hita Garcia et al. 2019, http://doi.org/10.5061/dryad.3qm4183).”
The journal, Insect Systematics and Diversity, launched by ESA in 2017, publishes research on systematics, evolution, and biodiversity of insects and related arthropods, including comparative and developmental morphology, conservation, behavior, taxonomy, molecular phylogenetics, paleobiology, natural history, and phylogeography.
The journal set out to host articles that utilize novel technologies or data types or describe emerging methods of research, ESA spokesperson Lisa Junker said. The new special collection on current techniques in morphology, she said, highlights how Insect Systematics and Diversity has become a premier outlet for integrative research combining multiple subdisciplines within the field.
"It" is the three-cornered alfalfa hopper, Spissistilus festinus, a lear-winged, wedge-shaped (thus the name "three-cornered") insect that's about a quarter of an inch long. That's about the size of a pomegranate seed.
And the spotlight will shine on the hopper on Wednesday, Dec. 5 when Cindy Preto--who recently received her master's degree in entomology from the University of California, Davis, studying with major professor Frank Zalom--delivers a UC Davis Department of Entomology and Nematology seminar.
Preto's hourlong seminar, titled “Behavior and Biology of the Three-Cornered Alfalfa Hopper in Vineyards," begins at 4:10 p.m. in 122 Briggs Hall, located on Kleiber Hall Drive. Preto received her bachelor's degree in viticulture and enology, with an entomology minor in agricultural pest management, from UC Davis in 2014.
Zalom, a distinguished professor in the department, a former director of the UC Statewide Integrated Pest Management Program (UC IPM), and a past president of the 7000-member Entomological Society of America (ESA), will introduce her.
Back in October of 2016, UC Davis-based research on the three-cornered alfalfa hopper and the Grapevine Red Blotch Disease grabbed the headlines. It made the cover story of a special focus issue, "Disease Management in the Genomics Era," in the journal Phytopathology.
Zalom and research biologist Mysore "Sudhi" Sudarshana of the USDA's Agriculture Research Services (ARS), who is based in the UC Davis Department of Plant Pathology, led the research.
In 2015, the Zalom team hypothesized that the three-cornered alfalfa hopper could transmit the Grapevine Red Blotch-associated virus, GRBaV, "based in part on phylogeneic analysis of coat protein sequences of 23 geminiviruses that revealed that GRBaV-CP was most similar to that of another geminivirus that was transmitted by another treehopper," explained Zalom, a distinguished professor of entomology with the UC Davis Department of Entomology and Nematology, and a past president of the Entomological Society of America
Their research, published in the journal, confirms that the alfalfa hopper “was able to both acquire the virus from a grapevine infested with GRBaV and transmit the virus to healthy grapevines in the laboratory.”
“In commercial vineyards, lateral shoots of grapevines girdled due to feed injury by the adult three-cornered alfalfa hopper also tested positive for the virus using digital PCR,” the scientists noted in their abstract. “These findings represent an important step in understanding the biology of GRBaV and develop management guidelines.”
The disease, first noticed in 2008 and attributed to a newly identified virus in 2012, is present in many major grape production regions of the United States and Canada. It can reduce fruit quality and ripening. (See this UC IPM document, written by Zalom and his colleagues.)
The scientific name, Spissistilus festinus, sounds a little festive--especially when mentioned during the holiday season.
Names can be deceiving.
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.
