"The Ja lab uses the fruit fly, Drosophila melanogaster, as a model organism for uncovering the genetic and neuronal mechanisms that drive aging, behavior, and disease," Ja says in his abstract. "Recently developed tools allow us to track fly feeding behavior with unparalleled resolution. These tools facilitate the identification of genes and circuits that regulate food intake at diverse time scales, including studies of: 1) meal intake; 2) daily (circadian) feeding rhythms; and 3) compensatory feeding in response to high or low quality food. Our studies of feeding behavior and nutrition also inform aging interventions, including a novel caloric restriction paradigm and an intermittent fasting regime that extends fly life through the stimulation of circadian-regulated autophagy. Overall, our fly studies shed light on basic neurobiological principles that drive animal behavior, providing insights that potentially inform the development of conserved therapeutic strategies."
Ja received his chemistry degree at UC Berkeley, working with Richard Mathies and Alex Glazer on DNA sequencing technologies. He pursued doctoral studies at the California Institute of Technology with Rich Roberts, utilizing mRNA display technology to identify modulators of G protein signaling. Ja remained at Cal Tech as a postdoctoral scholar to work with Seymour Benzer on developing longevity ‘drugs' in Drosophila. His laboratory focuses on aging and nutrition, animal behavior, and host-microbiome interactions.

The Bohart Museum of Entomology recently hosted an evening open house to engage and inform UC Davis Department of Entomology and Nematology biologists on how to streamline their efforts at all stages of their research, from collecting insects and arachnids to using the Bohart specimens.
More than two dozen scientists, including UC Davis undergraduates, graduate students, postdoctoral scholars, researchers, associates and faculty, attended. They gathered information on:
- Making wet, dry or cryo collections
- Donating, borrowing or sampling museum specimens from the Bohart or from collections around the world
- Prepare specimens and formatting labels
- Field collecting (equipment, permits, storing, regionally and internationally)
- Identifications services
- Language for grants, and budget development
- Science communication: public outreach, and broader impacts
UC Davis distinguished professor Lynn Kimsey, director of the Bohart Museum, led the event. Entomologist Jeff Smith, who curates the lepidoptera collection, offered a pinning demonstration. (See one of his previous videos.) Others assisting were other Bohart staff and associates, including the laboratory of arachnologist Jason Bond, the Evert and Marion Schlinger Endowed Chair, UC Davis Department of Entomology and Nematology, and associate dean, UC Davis College of Agricultural and Environmental Sciences.
The Bohart Museum has an online playlist of 11 short videos on "How to Make an Insect Collection." It was the brainchild of UC Davis distinguished professor James R. Carey, who led a class of entomology students 13 years ago to create tightly scripted clips, with an emphasis on brevity, simplicity and low cost.
The entire series can be viewed in less than 10 minutes. The clips range in length from 32 seconds to 77 seconds. UC Davis forensic entomologist Robert Kimsey provided the introductory narration for each clip. See Bohart web page for more information on insect collecting and links to the videos.

Kaya, who joined the UC Davis faculty in 1976 and retired in 2010, has known Lynn and her husband, Robert "Bob," for more than four decades. Both the Kimseys received their bachelor and doctoral degrees in entomology from UC Davis.
"I never had Lynn in a classroom situation, but she was always helpful in helping others ID insects," Kaya said. He and Lynn worked on a McKnight Foundation potato grant project in Peru for four years. He remembers Bob as a "super student in my insect pathology class."
Lynn, then Lynn Siri, received her bachelor's degree in 1975 and her doctorate in 1979, while Bob received his bachelor's degree in 1977 and his doctorate in 1984. Lynn joined the UC Davis faculty in 1989 and has directed the Bohart Museum since 1990. Bob, a forensic entomologist, joined the UC Davis faculty in 1984 as a lecturer. Both plan to retire this year.
Harry Kaya is internationally recognized for his contributions to insect pathology and insect nematology, which include more than 250 peer-reviewed publications. He co-authored an insect pathology book in 1993; co-edited another insect pathology book in 2012; and co-edited five books in several disciplines including forest entomology, entomopathogenic nematology, and invertebrate pathology.
He was named a fellow of the Entomological Society of America (ESA) in 2007.
At the seminar, co-organizer Lynn Lebeck, then executive director of the Association of Natural Biocontrol Producers, praised him as a top-notch researcher and as "a warm human being." She recalled the "many years of fun times and great research experiences with him." (See news story)
Kaya co-founded the journal Biological Control, and served as the co-editor of the first and second editions of Field Manual of Techniques in Invertebrate Pathology, Application and Evaluation of Pathogens for Control of Insects and other Invertebrate Pests.
Born and raised in Honolulu, Harry received his bachelor's degree in entomology in 1962 from the College of Tropical Agriculture, University of Hawaii (UH). He served in the U.S. Army, and after being discharged as a first lieutenant, earned his master's degree in entomology from UH in 1964, specializing in insect ecology. In 1970, UC Berkeley awarded him his doctoral degree in entomology. with research in insect pathology.
From 1971 to 1976, Kaya worked as an entomologist at the Connecticut Agricultural Experiment Station in New Haven and conducted research on biological control of forest insects. In 1976, he joined the UC Davis faculty as an assistant professor, attaining the rank of full professor in 1984. He became a distinguished professor of entomology in 2008.
Kaya chaired the Department of Nematology from 1994 to 2001. He also served as an officer in the Society of Invertebrate Pathology (treasurer, 1990–1994, vice-president, 2000–2002, and president-elect 2002–2004), and was one of the founding editors of the journal Biological Control.
Highly honored by his peers, Kaya received the 1998 C. W. Woodworth Award, the highest honor presented by the Pacific Branch, ESA. In 2000, he received the 2000 Recognition Award in Entomology from ESA and Fellow of the Society of Nematologists. The Society for Invertebrate Pathology and UH also presented him with several awards.
In honoring him as a Fellow, ESA posted this on its website: "Kaya has mentored many graduate students and post-doctoral researchers who have proceeded to establish their own careers and excel in research and teaching. His laboratory hosted and trained many visiting scientists from other countries who have become leaders in research with entomopathogenic nematodes upon their return to their own countries. These include scientists from Korea, Thailand, Turkey, Mexico, Ukraine, and Peru. Kaya maintains a strong relationship with many of them and he had research projects with scientists from Korea and Turkey."
Kaya's first four PhD students--Raquel Alatorre, Arnold Hara, Phyllis Hotchkin {Weintraub) and Robin Goblin-Davis--are all retired from their faculty and research positions. Arnold Hara died Nov. 18, 2022.
Kaya resides in Davis with his wife, Joanna. He enjoys spending time with his grandchildren and gardening, and used to fish with colleague Les Ehler (1946-2016). "No fishing since Les passed away," he related.
One of his granddaughters, Madelyn Lee, a freshman at UC Riverside, may follow in his footsteps. "She has always been interested in the biological sciences and has become an active member of the Entomology Club at Riverside. She is thinking about being an entomology major."

The open house, themed "Social Wasps," is free and family friendly. Parking is also free.
Kimsey defines social wasps as "wasps that live together and cooperate in a colony, with female workers and a queen; only the queen has babies."
What drew her to study social wasps? "I just like stinging things in general and their anatomy and social behavior are really interesting."
Kimsey lists some of the common myths about social wasps as:
- They are often seen as malevolent beings out to get you and will chase you
- That they serve no purpose except to annoy us
- If you're allergic to bee stings you'll be allergic to wasp stings
- A copper penny place on a sting will make it go away
The public should know that social wasps "provide valuable ecosystem services; do pest control, and assist in nutrient recycling and pollination," she said.
"There are about 2,000 described species of social wasps worldwide," Kimsey said, and probably around 500 species undescribed.
The Bohart Museum has approximately 50,000 vespids in its collection, "and clearly the most popular is the Northern giant hornet, Vespa mandarinia," she said. The press dubbed it "Murder hornet." The Entomological Society of America recently changed its common name, "the Asian giant hornet," to "northern giant hornet."
The hornet, considered the world's largest hornet, is native to Asia. It was first detected in the Pacific Northwest in 2019, and with nests found in 2021.
Kimsey is a recognized authority on insect biodiversity, systematics and biogeography of parasitic wasps, urban entomology, civil forensic entomology, and arthropod-related industrial hygiene. She holds bachelor and doctoral degrees from UC Davis. She joined UC Davis entomology faculty in 1989, and has served as director of the Bohart Museum since 1990.
She plans to retire this year, but not from research and public service.
Kimsey served as president of the International Society of Hymenopterists from 2002-2004, and as a member of the board of directors of the Natural Science Collections Alliance in 2000 and 2001. The Pacific Branch, Entomological Society of Ameica (PBESA) singled her out for its highest honor, the C. W. Woodworth Award, in 2020. She received the PBESA Systematics, Evolution, and Biodiversity Award in 2014 and was a member of 'The Bee Team' that won the PBESA Outstanding Team Award in 2013. The UC Davis Academic Senate honored her with its Distinguished Scholarly Public Service Award in 2016 in recognition of her outstanding work. She received the UC Davis College of Agricultural and Environmental Sciences (CA&ES) Exceptional Faculty Award in 2023.
The Bohart Museum also houses a live "petting zoo" (Madagascar hissing cockroaches, stick insects, tarantulas and more), and an insect-themed gift shop.
