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.
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.
Theme of this year's Picnic Day is "Growing Together." The schedule can be downloaded from the campus website.

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.
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.
