What's a picnic without bugs!
The UC Davis Department of Entomology and Nematology is gearing up for the 110th annual UC Davis Picnic Day, set April 20.
This year, all of the entomology exhibits, including those at the Bohart Museum of Entomology, will be at Briggs Hall. (The Bohart Museum headquarters in the Academic Surge Building will be closed on Picnic Day.)
Picnic Day at Briggs Hall is from 9 a.m. to 5 p.m. Some of the activities will closer earlier.
The list of events and activities in and around Briggs Hall will include:
Bug Doctor
Briggs Hall Entryway
Graduate students will answer questions about insects. What's that bug? Attendees are encouraged to bring an insect or photo for identification.
Cockroach Races
Front of Briggs Hall
American cockroaches, Periplaneta americana, from Bob Kimsey's forensic lab, race on a specially made track, while roach fans cheer for their favorites. (Sometimes the athletes are named for faculty, friends or bystanders.)
Medical Entomology
122 Briggs Hall
Carla-Cristina "CC" Melo Edwards of the Geoffrey Attardo lab is coordinating the medical entomology display. Her research focuses on investigating the physiological mechanisms underlying pyrethroid resistance in Aedes aegypti (the yellow fever mosquito).
Diversity of Arachnids
122 Briggs Hall
Doctoral student Emma Jochim of the Jason Bond lab is coordinating an exhibit she created last year to display the diversity of arachnids, such as vinegaroons, whip spiders, tarantulas, and scorpions. "We'll have live animals and fact sheets that will give a general overview of their diversity, behavior, and habitat," Jochim said. "I'll also bring some curated specimens to show what goes into creating a scientific collection and talk about why collections are important for understanding biodiversity. "
Maggot Art
Briggs Courtyard
Artists--children and adults alike--create maggot art by dipping a live maggot into water-based, non-toxic paint. It's suitable for framing (or at least a spot on the refrigerator door). This event will close at 3 p.m. this year (last year it was at 5 p.m.)
Dr. Death
122 Briggs Hall
Forensic entomologist Robert Kimsey will display and discuss his work in his "Dr. Death" booth. Last year Kimsey pin-mounted and identified flies from various cases and research efforts, and displayed studies on the sequence of development of individual maggots, calling attention to the development and sequence of communities of insect maggots. "By these means, approximations about how long a person has been dead can be made," he told the crowd.
Entomology at UC Davis
122 Briggs Hall
Displays of insects, including bees, ants and more. Graduate students, faculty and emeriti will staff the tables.
Bohart Museum of Entomology
Front of Briggs Hall
A pop-up tent, staffed by the Bohart Museum, will include stick insects (walking sticks) and Madagascar hissing cockroaches. "We are excited to be part of the bigger department's offerings," said Tabatha Yang, education and outreach coordinator. Give-aways are also planned.
Fly-Tying
Briggs Hall courtyard
Fly Fishers of Davis will show attendees how to tie a fly. The recipients take home the flies.
Insect-Themed T-Shirt Sales
Briggs Hall entryway
Members of the Entomology Graduate Student Association (EGSA), led by president Mia Lippey, will be selling their popular insect-themed t-shirts, including The Beetles. The T-shirt, EGSA's all-time best seller, is a take-off of the cover of The Beetles' Abbey Road alum. However, instead of the Beatles crossing the road in a single file, four beetles (family names Phengogidae, Curculionidae, Cerambycidae and Scarabaeidae) do so.
Mosquito Control Booth
Entrance to Briggs (below front steps)
Sacramento-Yolo Mosquito and Vector Control District will be providing information on mosquitoes, answering questions, and handing out give-a-ways, including mosquito repellent.
UC Statewide Integrated Pest Management (UC IPM)
Briggs Hall Courtyard
“We plan to have many of our usual materials on display and will be giving out the live lady beetles (aka ladybugs) again,” said urban and community IPM educator Lauren Fordyce. “We purchase them from a local garden center. In addition to that, we plan to have a prize wheel that adults and kids can spin, answer a question, and win a prize if they answer correctly. We may also have temporary insect tattoos to give away.”

The Nematode Collection, showcased in the Katherine Esau Science Hall, drew hundreds of visitors wanting to know more about the organism commonly known as "roundworm."
Nematologist Shahid Siddique, associate professor, UC Davis Department of Entomology and Nematology, and Alison Blundell, a doctoral candidate in Plant Pathology, coordinated the displays.
The collection highlighted both animal and plant parasitic nematodes. Visitors examined the preserved specimens and watched the movement of live free-living C. elegans (good nematodes) via a microscope.
Among the displays:
Animal Parasitic Nematodes: Anisakis nematodes from a Minke whale stomach, heart of a dog infected with heartworms; dog intestine infected with whipworms; a horse stomach parasite community including Parascaris, tapeworms and botfly larvae; adult raccoon roundworms; tree swallow infected with Diplotriaena nematode; and whipworms isolated from the human intestine.
Plant Parasitic Nematodes: Celery, sugar beet, and yam infected with root-knot nematodes; fresh tomato root infected with root-knot nematodes, and a mustard plant infected with cyst nematodes.
"Plant-parasitic nematodes are destructive pests causing losses of billions of dollars annually," Siddique writes on his website. "Economic, health, and environmental considerations make natural host plant resistance a preferred strategy for nematode control, but there are limitations to this approach. In many cases, the resistance conferred by resistance genes is partial, and some of the nematodes are able to survive. Similarly, nematode resistance genes are often effective against only one or a few species, whereas plants are exposed to several pathogens in the field. Another concern is the emergence of pathotypes that can overcome resistance. In view of all these limitations, it is important to identify additional mechanisms and tools that can be used to develop novel and sustainable approaches to the management of nematodes."
Research in the Siddique lab focuses on basic as well as applied aspects of interaction between parasitic nematodes and their host plants. "The long-term object of our research is not only to enhance our understanding of molecular aspects of plant–nematode interaction but also to use this knowledge to provide new resources for reducing the impact of nematodes on crop plants in California," he says.
The 13th annual Biodiversity Museum Day featured 10 museums or collections: Anthropology Museum, Arboretum and Public Garden, Bohart Museum of Entomology, Botanical Conservatory, California Raptor Center, Center for Plant Diversity, Nematode Collection, Museum of Wildlife and Fish Biology, Paleontology Collection, and Phaff Yeast Culture Collection.

You'll see specimens and get to talk to nematologists during the 13th annual UC Davis Biodiversity Museum Day on Saturday, Feb. 10. The free and family friendly event, known as “Super Science Day," will showcase 10 museums or collections.
The nematode collection, headed by Shahid Siddique, associate professor, Department of Entomology and Nematology, will be open from 10 a.m. to 2 p.m.. in the Katherine Esau Science Hall, off Kleiber Hall Drive.
“Our collection will highlight both animal and plant parasitic nematodes,” said graduate student Alison Blundell of the Siddique lab. “We will have mostly all preserved specimens from our nematode collection for the community to look at, and some live free-living (good nematodes) under the microscope for viewing. We hope to inspire people to understand what a nematode is and how they can impact their own lives!”
“We will have preserved specimens of common crops and plants you see in your garden infected with nematodes,” she added. “We also plan to have live C. elegans (Caenorhabditis elegans) to watch how they move through the environment. Come talk to experts in the field and see why worms are cool and you will receive a cool magic worm to take home as well!”
What visitors can expect to see:
- Anthropology Museum, 328 Young Hall and grounds, open from noon to 4 p.m.
- Arboretum and Public Garden, Habitat Gardens in the Environmental GATEway, adjacent to the Arboretum Teaching Nursery on Garrod Drive, 10 a.m. to 2 p.m.

Last year's Biodiversity Museum Day drew some 4000 people, said chair Tabatha Yang, education and outreach coordinator for the Bohart of Museum of Entomology who co-founded the event.
"Traditionally UC Davis Biodiversity Museum Day is a free, educational event for the community where visitors get to connect with UC Davis scientists from undergraduate students to staff to emeritus professors," Yang posted on the website. "In 2021, we pivoted to a month-long, virtual program. In 2022, also because of COVID regulations, we held the event in the UC Davis Conference Center as an 'expo.' In 2023 and again this year in 2024 we continued to maintain that spirit and were excited to have the event in our near our home departments."
