The UC Davis Department of Entomology and Nematology and the Bohart Museum of Entomology will be participating in the virtual 107th annual UC Davis Picnic Day on Saturday, April 17, a traditional event being held untraditionally this year due to the COVID-19 pandemic.
The entomological events will include cockroach racing and a series of talks. Among them: Bohart Museum associate and natural historian Greg Kareofelas will present a pre-recorded video on Gulf Fritillary butterflies and entomologist Jeff Smith, the Bohart's volunteer curator of the Lepidoptera collection, will deliver a live Zoom talk on butterfly and moth mimicry from 1 to 2 p.m.
Said Smith: "For my presentation on mimicry within Lepidoptera, it will briefly mention camouflage and spend most of the time on mimicry for defense-- mimics of toxic or distasteful species, mimicry using odors or sounds, mimics of snakes or spiders, and mimics of non-food materials such as bird feces."
More events--and the schedule--are pending.
The Bohart Museum, temporarily closed, is located in Room 1124 of the Academic Surge Building on Crocker Lane. Directed by Professor Lynn Kimsey, the Bohart Museum includes nearly eight million insect specimens, a live "petting zoo" (Madagascar hissing cockroaches, stick insects and tarantulas) and an online gift shop stocked with insect-themed t-shirts, jewelry, hoodies, books, posters and more.
Discovering Silver Linings
This year's theme is “Discovering Silver Linings.” Despite all that has happened this year, the UC Davis community has continued to find silver linings everywhere, the Picnic Day officials reported on their website. "Our campus always strives to inspire hope and works towards a better and brighter tomorrow."
Last year's in-person events also were canceled and some virtual events took place.
"This long-standing campus tradition began in 1909 when the University Farm invited the surrounding community to view their new dairy barn. Two thousand visitors attended, bringing picnics to complement the coffee, cream, and sugar provided by the University. Following the success of the 1909 picnic, the faculty of the University Farm continued to plan and sponsor the event until a student committee took over the task in 1912. Through the years of Picnic Day history, the event has only been canceled five times. In 1924, an outbreak of hoof-and-mouth disease among the cowherds caused the first cancellation. In 1938, delayed construction of the gymnasium, which was needed to accommodate the ever-increasing number of participants, led to a second cancellation. During World War II, the Army Signal Corps controlled the campus, and Picnic Day disappeared from 1943 to 1945. Since 1946, Picnic Day has been growing strong and now boasts an annual attendance of more than 70,000 people. This year, there will be more than 200 events on campus and an estimated 75,000 visitors attending this special event. Since 1959, the parade was extended to include downtown Davis to celebrate the fact that Davis became a separate UC campus and not just the Farm School for UC Berkeley."

It chronicles how Hammock's basic research on caterpillars--how caterpillars become butterflies--led to key discoveries about chronic pain, including diabetic pain.
It includes information on Hammock's collaborator, John Imig, professor of pharmacology and toxicology at the Medical College of Wisconsin, who recently received a $2.3 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases "to investigate the development of a drug to treat type 2 diabetes and metabolic syndrome."
"But what we didn't tell you is that this translational grant is all thanks to some caterpillars in California and decades of research," wrote communication specialist Karri Stock. "It's a tale of pure curiosity with a great lesson for budding scientists and the public alike: You can't always predict where basic science discoveries will lead."
She related how, more than 40 years ago, a young entomologist in California named Bruce Hammock found a key enzyme (epoxide hydrolase or EH) in the metamorphosis of caterpillars into butterflies. "The enzyme degrades a caterpillar's juvenile hormone, allowing it to move from the larval stage into an adult insect. Early in his career, Dr. Hammock found that if he exploited this EH and prevented larvae from becoming adults, he had on his hands an effective genetically engineered insecticide."
Then came the basic science and fundamental questions that Hammock asked. "Does the enzyme occur in plants? Does it occur in mammals?"
"And it turns out that it does, particularly as soluble epoxide hydrolase (sEH) in mammals, including mice and humans, and its distribution suggested it was involved in regulatory biology," Stock wrote. She went on to detail the collaboration of Hammock and Imig. Read the entire MCW story here.
Hammock's work has drawn national and international attention. Groundbreaking neuropathic pain research emanating from the Hammock lab made Discover magazine's Top 100 Science Stories of 2015 ranking among the Top 15 in the medicine/genetics category.
The UC Davis research was singled out for its “Endoplasmic Reticulum Stress in the Peripheral Nervous System is a Significant Driver of Neuropathic Pain,” published in July 2015 in the Proceedings of the National Academy of Sciences. (See UC Davis news story).
Highly honored by his peers, Hammock is a fellow of the National Academy of Inventors, which honors academic invention and encourages translations of inventions to benefit society. He is a member of the U.S. National Academy of Sciences, a fellow of the Entomological Society of America, and the recipient of the Bernard B. Brodie Award in Drug Metabolism, sponsored by the America Society for Pharmacology and Experimental Therapeutics. He directs the campuswide Superfund Research Program, National Institutes of Health Biotechnology Training Program, and the National Institute of Environmental Health Sciences (NIEHS) Combined Analytical Laboratory.
