Sarah Silverman, a doctoral candidate who is studying insect demography at UC Davis with major professor James R. Carey, won a second-place award in her category.
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)."
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.”
Silverman gave 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.”
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. Her work at UC Davis is in the field of insect demography. “I specifically study insect lifespan in the wild, 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,” she said.
At its annual meetings, the ESA offers graduate students the opportunity to present their research and win coveted prizes. The first-place President's Prize recipient receives a one-year free membership in ESA, a $75 cash prize, and a certificate. The second-place winner receives a one-year free membership in ESA and a certificate.
The oral presentations are evaluated 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.
Boudinot's previous President's Prizes were for work on the male genitalia of ants, and for providing the first male-based identification material for the ant genera of the New World.
Ants are highly diverse, with over 13,000 known species, Boudinot said. "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."
The UC Davis Department of Entomology and Nematology is planning scores of insect-related activities for the 103rd annual campuswide UC Davis Picnic Day on Saturday, April 22.
What's new this year in the department's line-up will be an insect scavenger hunt, replacing the Pollinator Pavillion, said Brendon Boudinot of the Phil Ward lab, chair of the department's Picnic Day Committee.
"Visitors will search for and identify insects in display boxes and be rewarded with stickers," Boudinot said.
The campuswide Picnic Day gets underway at 9:30 a.m. with an opening ceremony by the grandstands on North Quad Ave., across from Wickson Hall. The parade starts at 10 a.m. from the same site. Announcement locations are at 2nd and D streets in downtown Davis; F Street in front of PDQ Fingerprinting, and 3rd and C streets in downtown Davis. The UC Davis Entomology Club, advised by forensic entomologist Bob Kimsey, will enter its popular black widow float.
The Briggs Hall activities will be open from 10 a.m. to 4 p.m., but the cockroach races will close at 2 p.m.
The list of activities at Briggs:
- Honey Tasting (You can sample varietals of honey)
- Bug Doctor (The doctor is in!)
- Cockroach Races (Pick a winner)
- Scavenger Hunt (Do you know your insects?)
- Dr. Death (Forensic entomologist Robert Kimsey will answer your questions)
- Insect Face Painting (Get a bee, lady beetle or another insect painted on your face)
- Little Swimmers and Fly Tying (Watch and identify aquatic insects, a project from the Sharon Lawler lab, and learn "how to tie a fly" from the Fly Fishers of Davis
- Maggot Art (Dip a maggot into a water-based, non-toxic paint and create a painting suitable for framing)
- UC Statewide Integrated Pest Management (UC IPM) (See their many publications and ask questions; youngsters can receive a vial of free lady beetles, aka ladybugs)
- T-shirt sales by the UC Davis Entomology Graduate Students' Association (popular t-shirts include beetles and honey bees)
- Social insects, insect forestry, medical entomology, and more (See a honey bee observation hive from the Harry H. Laidlaw Jr. Honey Bee Research Facility and ants from the Phil Ward lab; and also learn about forest insects and mosquitoes. The Sacramento-Yolo Mosquito and Vector Control District will staff a booth)
The Bohart Museum of Entomology in Room 1124 of the Academic Surge Building will swing open its doors from 10 a.m. to 3 p.m. The theme: "Bigger, Better and Buglier: Impressive Science at the Bohart." This will be an opportunity to see some of the nearly eight million specimens, visit the live petting zoo (Madagascar hissing cockroaches, walking sticks and taranatulas) and ask questions of the scientists.
The nematology collection will be on display in the Sciences Laboratory Building, across from Briggs.
The UC Davis Linnaean Games Team has successfully defended its national championship.
The team, comprised of three UC Davis Department of Entomology and Nematology graduate students, defeated the University of Georgia in the championship round.
The annual Linnaean Games, sponsored by the Entomological Society of America (ESA), took place at ESA's recent meeting in Orlando, Fla., held in conjunction with the International Congress of Entomology meeting.
UC Davis team members are captain Ralph Washington, a third-year graduate student; Brendon Boudinot, a third-year graduate student; and Emily Bick, a second-year graduate student. They defeated the University of Georgia, the 2012 winner, in the championship match (score, UC Davis 145; Georgia, 55). The UC Davis entomologists earlier outscored Ohio State University, North Carolina State University (champions in 2014), and Texas A&M in advancing to the finals.
The ESA 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. The winning team receives a trophy cup for the department, and each individual, a plaque.
Washington is studying for his doctorate with major professors Steve Nadler and Brian Johnson, who respectively specialize in systematics and evolutionary biology of nematodes and the evolution, behavior, genetics, and health of honey bees; Boudinot with major professor Phil Ward, systematics and evolutionary biology of ants; and Bick, with major professor Christian Nansen. Bick is working on ecosystem models to optimize pest management in two systems: invasive aquatic weed species water hyacinth and its biological control agent, Neochetina bruchi; and working to control Lygus bugs using alfalfa as a trap crop in strawberries. UC Davis Extension entomologist Larry Godfrey serves as the advisor.
Below are some of the questions that the UC Davis team answered correctly in the championship match.
- Question: “You have just moved into an apartment that has been vacant for weeks but whose prior owners had several cats and dogs. A very few days after you move in you are bitten by a huge number of cat fleas that seem to have appeared out of nowhere. What characteristic behavior of cat fleas biology is probably responsible for this?”
Answer: “Cat flea pupae eclose in response to the presence of a host.”
Question: Insects inhabiting a very thin water film such as splash zones marginal to streams are called what?
- Question: The insect order Notoptera unites what two former insect orders?
Answer: Notoptera unites Mantophasmatodea and Grylloblattodea
- Question: What are the two obvious clinical symptoms that someone is suffering from onchocerciasis?
Answer: Blindness and hanging tissue around lymph nodes, often times the scrotum.
- Question: What is the common name for the zygentoman pest that thrives in high humidity and high temperatures and is often found in boiler rooms?
Answer: The firebrat, Thermobia domestica.
- Question: Projection neurons travel across what two major regions of the insect brain?
Answer: The protocerebrum and the deutocerebrum.
