Tabuloc's topic is "Environmental and Anthropogenic Impact on Insect Gene Expression and Physiology." Her seminar also will be virtual. The Zoom link:
https://ucdavis.zoom.us/j/95882849672.
Tabuloc will be introduced by Professor Chiu, her advisor. A pre-seminar coffee session is set from 3:30 to 4:10 p.m. in Briggs 158.
"Natural environmental factors and anthropogenic disturbances can modulate gene expression, resulting in alteration of organismal phenotype," Tabuloc says in her abstract. "In the first part of my thesis project, I used Drosophila melanogaster as an insect model to understand the mechanisms by which 24-hour light-dark cycles can regulate rhythmic changes in the chromatin to generate circadian rhythms of gene expression and orchestrate daily biological rhythms. I observed that two clock proteins, CLOCK and TIMELESS, regulate daily rhythmicity in the binding of BRAHMA, a chromatin remodeler, to DNA spanning clock-controlled genes to facilitate their rhythmic gene expression cycles. Moreover, because TIMELESS degrades in the presence of light, my results provide new insights into how light affects DNA structure and gene expression."
"In the second part of my thesis project, I investigated the impact of insecticide applications on the fruit pest Drosophila suzukii," Tabulocsaid. "Specifically, I performed RNA sequencing analysis on D. suzukii flies that are either susceptible or resistant to common insecticides to determine genetic mechanisms underlying insecticide resistance in this agricultural pest. My results revealed that enhanced metabolic detoxification confers pyrethroid resistance while spinosad resistance is the result of both metabolic and penetration resistance. Finally, we identified alternative splicing as an additional mechanism of resistance. These results will facilitate the development of efficient molecular diagnostics to identify insecticide resistance in the field and enable growers to adjust D. suzukii spray programs to control this devastating pest more effectively."
Christine received her bachelor of science degree in biochemistry and molecular biology from UC Davis in 2015. She joined the Chiu lab as an undergraduate research assistant in 2012. "Much of my work in the lab has involved different agricultural pests and investigating the molecular aspects contributing to the insect's ability to be an effective pest," she says on the Chiu lab website. "My current focus is to investigate the effects of climatic change on gene expression of an invasive pest and determine whether there is a correlation to resistance and survival. In addition to pest management research, I am also studying a kinase of a core clock protein in Drosophila melanogaster and hoping to dissect its functional contribution to the molecular oscillator."
The UC Davis Department of Entomology and Nematology's winter seminars are held on Wednesdays at 4:10 p.m. in 122 Briggs Hall. All are virtual. They are coordinated by urban landscape entomologist Emily Meineke, assistant professor. (See schedule.) She may be reached at ekmeineke@ucdavis.edu for technical issues.

But have you ever heard of a song featuring the three-cornered alfalfa hopper, Spissistilus festinus, and another one spotlighting the male insect organ, the aedeagus?
And composed by a graduate student at the University of California, Davis, and performed by seven insect-attired UC Davis doctoral students?
That's what happened during the recent UC Davis Picnic Day celebration when the septet gathered in front of Briggs Hall to perform three songs composed by talented musician and entomologist Michael Bollinger, enrolled in the master's degree program, UC Davis Department of Entomology and Nematology. The group performed Bollinger's compositions, “E Major Homeboy (Spissistilus festinus),” “Tragedy (of the Clocks)," and "Jackson's Song (Aedeagal Bits)," as well as a cover song, “Island in the Sun” by Weezer.
The performance went well. Very well. So did Picnic Day.
“My goal was to make sure Picnic Day worked overall, and that, for the band, the sounds were balanced and each of the elements could be heard,” said emcee and band member Brendon Boudinot, president of the UC Davis Entomology Graduate Student Association (EGSA) and a doctoral candidate specializing in ant evolution and classification.
The “Entomology at UC Davis” exhibit at Briggs Hall, the work of the UC Davis Department of Entomology and Nematology, won the campuswide “At One With Nature” category. And the band? It drew loud applause and high praise from the standing crowd.
Their name: “The Entomology Band.” (No take-offs of the iconic “Beatles,” “Buddy Holly and the Crickets” or “Adam and the Ants.”)
Bollinger's original songs capped a day of insect-related activities that included maggot art, cockroach races, nematode identification, scavenger hunts, and honey tasting.
- Molecular geneticist and drummer Yao “Fruit Fly” Cai of the Joanna Chiu lab, dressed in a fruit fly costume, Drosophila melanogaster, which he described as “our favorite model organism in Insecta!”
- Bark beetle specialist and rhythm guitarist Jackson “Darth Beetle” Audley of the Steve Seybold lab, portrayed an Asian longhorned beetle, Anoplophora glabripennis
- Honey bee researcher and bass guitarist Wei “Silverfish” Lin of the Brian Johnson lab, wore a costume that celebrated his moniker, Lepisma saccharina, a small, wingless insect in the order Zygentoma
- Ant specialist and keyboard artist Zachary “Leptanilla” Griebenow of the Phil Ward lab, dressed as “a generic male leptanilline ant (Formicidae: Leptanillinae).” He said: “The yellow color “is not anywhere near so vivid in real life.”
- Systematist and tenor saxophonist Jill “Jillus Saximus” Oberski of the Phil Ward lab, dressed as a “generalized heteropteran,” which she described as “most likely a member of the family Acanthosomatidae (shield bug) or Pentatomidae (stink bug). My family and friends have called me Jillybug, so I came to be the band's representative of Hemiptera.”
- Molecular geneticist and vocalist Christine “The Clock” Tabuloc of the Joanna Chiu lab, wrapped herself in butterfly wings
- Ant specialist and bass guitarist Brendon “Hype Man-tis” Boudinot of the Phil Ward lab, dressed in a green helmet, a blue and gold EGSA bee shirt and a UC Davis cow costume to showcase his department and campus-wide love of bovines.
The seven band members share a love of music.
Drummer Yao Cai, who grew up in Southeast China and holds an undergraduate degree in plant protection and a master's degree from China Agricultural University, has been playing drums since age 17. “We formed as a short-lived band for a show. After that, I realized that I really wanted to keep playing and improved my drum techniques. Thus, we started another band in college and played for six years in college, as an undergrad and graduate student.
“It is very interesting that I was in a band that was the first band in Department of Entomology in China Agricultural University and now we started the first band in Department of Entomology at UC Davis.”
Rhythm guitarist Jackson Audley said he “started learning to play the guitar when I was about 11-12 ish. The first band I joined was a Blink-182 cover band, in which I played the bass guitar, and we played together for most of eighth grade. Then in early high school I joined a Smashing Pumpkins/Radiohead cover band as the second guitarist. Shortly after joining that band, we started making predominantly original music. By the end of high school, we had played a few small shows around the Atlanta area and had recorded a few songs. Unfortunately, the band did not survive the transition into university and we broke up.”
Since then he's mostly played “for fun and I like to jam with folks.”
Jill Oberski, a native of Twin Cities, grew up mostly in Chaska, Minn., “a sleepy suburb of Minnesota.” She received her bachelor's degree in Macalester College in Saint Paul, Minn., where she double-majored in biology and German studies.
“I started playing the piano in kindergarten, and switched to saxophone in fifth grade,” Oberski related. “I played classical and jazz in my school bands from sixth grade through college, and pit orchestra / pep band / marching band in high school as well. I've always been better at classical than rock/jazz/Latin.”
“I probably reached my highest point in late high school, when I served as co-section leader for the saxes in the Minnesota all-state symphonic band--we even got to play a concert in Minneapolis' orchestra hall. These days I'm only involved in the entomology band and some very casual ukulele playing.”
Brendon Boudinot, who received his bachelor's degree in entomology at the Evergreen State College, Olympia, Wash., performed on a metallic sky-blue bass. “I just love art,” he said. “Music is a family thing for me in a number of different ways. Although I have played instruments alone or in groups for many years, nothing really clicked in me until I heard Michael and Yao play together. They shred.”
“The Entomology Band is special to me, and I am just glad I could be a part of it.”
Vocalist Christine Anne Tabuloc, who grew up in the Los Angeles area and received her bachelor's degree from UC Davis in biochemistry and molecular biology, says she does not play an instrument. “I'm far less talented than everyone else in the group,” she quipped. “I've been singing for as long as I can remember. I've been writing lyrics since elementary school. However, I never got around to getting music written for them. I was in choir before and have had solos but that's pretty much it.”
Bass guitarist Wei Lin, who grew up in Xiamen, "a beautiful island in southern China," received his bachelor's and master's degree in China Agricultural University, majoring in plant protection and entomology. “This was my first experience in a band. I just started to learn bass last year when this band was built.”
Following the four-set gig, Boudinot told the appreciative crowd, “That's all we know!”
Pending performances? “The band,” he said, “is on hiatus.”
Or diapause.
