UC Davis Distinguished Professor Walter Leal: Third Academic Senate Award
The UC Davis Academic Senate today announced that UC Davis distinguished professor Walter Leal of the Department of Molecular and Cellular Biology and former professor and chair of the Department of Entomology, is the recipient of the Faculty Distinguished Research Award.
And with that award, comes Academic Senate history.
Leal is the first UC Davis faculty member to be honored by the Academic Senate for all three of its awards celebrating outstanding teaching, public service and research. In 2020, the Academic Senate awarded him the Distinguished Teaching Award for Undergraduate Teaching, and in 2022 Distinguished Scholarly Public Service Award.
“Dr. Leal is an internationally recognized entomologist and a world leader in his field for his groundbreaking and transformative research in insect olfaction and chemical ecology,” said nominator UC Davis distinguished professor Bruce Hammock of the Department of Entomology and Nematology, who won the Academic Senate's Faculty Research Award in 2001 and its Distinguished Teaching (Graduate Students/Professional) Award in 2008.
Leal said he's honored and humbled to receive the award, but emphasized that “it's a team effort.” See more.

The research, “Circabidian Rhythm of Sex Pheromone Reception in a Scarab Beetle,” published in the Jan. 18 edition of Current Biology, marks the first sex pheromone receptor identified in Coleoptera, the order of beetles.
While most insects exhibit a 24-hour circadian rhythm that regulates their behavior and physiology, the large black chafer beetle, Holotrichia parallela, operates on a 48-hour clock, said Leal, a global expert on insect olfaction and communication. A professor in the Department of Molecular and Cellular Biology, he is a former professor and chair of the UC Davis Department of Entomology, now the Department of Entomology and Nematology.
“Insects smell with their antennae,” said Leal, who has unraveled the molecular mechanisms of mosquitoes, true bugs, long horned beetles, moths and other insects. “They have a sophisticated olfactory system and can selectively detect minute amounts of odorants.”
The female H. parallela emerges from the soil every other night, after sunset, climbs the canopy of the host plant, and seeks a mate by releasing a sex pheromone. Leal wanted to know if the males are also on a 48-hour rhythm clock, and he wanted to identify the elusive male gene in the pheromone receptor that allows the male to scent the female's pheromone.
The answers: “yes” and “yes.”
“I have been waiting for almost three decades to answer these questions,” Leal said. “I identified the sex pheromone of this beetle species in 1993 while working for the Ministry of Agriculture and Forestry of Japan. At that time, I found for the first time a very unusual sex pheromone, which is derived from an amino acid. Now similar sex pheromones have been identified from many species of beetles.”
“Also, we showed that females produce the sex pheromone every other night,” Leal said. “The burning question in biology is what males do about sensing or smelling the female sex pheromone. Back then, we had no idea how insects sense smell. With the advancements in sequencing, we identified all potential receptors and identified which one senses the sex pheromone. COVID happened and delayed our research collaboration. Finally, we found that the receptor is expressed every other day.”
“This is remarkable,” Leal said. “How do they know when it is a 'date night' or a non-calling night? It is still a mystery, but we will find out one day.”
Leal and Yin and their team pointed out that virtually all life on Earth experiences a 24-hour circadian rhythm, which affects almost all behaviors, including sexual activity and mating.
Leal, a native of Brazil, received his Ph.D. in applied biochemistry from the University of Tsukuba, Japan, with subsequent postdoctoral training in entomology and chemical ecology at the National Institute of Sericultural and Entomological Science and Cornell University, respectively. He was the first non-Japanese person to earn tenure at Japan's Ministry of Agriculture, Forestry, and Fisheries.
Leal, who joined the UC Davis faculty in 2000, is a newly elected trustee of the Royal Entomological Society, the first UC Davis scientist to be elected a trustee. He chaired the UC Davis Department of Entomology in 2006-2008 before accepting a position in 2008 as professor of biochemistry in the Department of Molecular and Cellular Biology. His many honors include Fellow of the Entomological Society of America (2009), American Association for the Advancement of Science (2005), and the National Academy of Inventors (2019).

Elsevier. Elsevier, a global information analytics company that helps institutions and professionals progress science, advance healthcare and improve performance, published its "science-wide author databases of standardized citation indicators" on Oct. 4, 2023. The ranking of scientists is at https://elsevier.digitalcommonsdata.com/datasets/btchxktzyw. It is a publicly available database "of top-cited scientists that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator (c-score). Separate data are shown for career-long and, separately, for single recent year impact. Metrics with and without self-citations and ratio of citations to citing papers are given. Scientists are classified into 22 scientific fields and 174 sub-fields according to the standard Science-Metrix classification. Field- and subfield-specific percentiles are also provided for all scientists with at least 5 papers. Career-long data are updated to end-of-2022 and single recent year data pertain to citations received during calendar year 2022. The selection is based on the top 100,000 scientists by c-score (with and without self-citations) or a percentile rank of 2% or above in the sub-field. This version (6) is based on the October 1, 2023 snapshot from Scopus, updated to end of citation year 2022. This work uses Scopus data provided by Elsevier through ICSR Lab (https://www.elsevier.com/icsr/icsrlab). Calculations were performed using all Scopus author profiles as of October 1, 2023. If an author is not on the list it is simply because the composite indicator value was not high enough to appear on the list. It does not mean that the author does not do good work."

"Summer is nearly over, and the fall quarter begins soon," said Leal, professor of biochemistry in the Department of Molecular and Cellular Biology and former professor and chair of the Department of Entomology (now the Department of Entomology and Nematology). "Let's pause and express our gratitude to our colleagues who transitioned to emeriti status this summer."
"For decades, they strived to make UC Davis a better place, and many will remain engaged with research, teaching, and public service," he noted.
Leal said the late Distinguished Emeritus Professor Robbin Thorp (1933-2019) epitomizes how emeriti contribute to UC Davis. Thorp, a 30-year member of the entomology faculty, and a tireless advocate of pollinator species protection and conservation, retired in 1994, but he continued working until several weeks before his death on June 7, 2019, at age 85. In 2014, he co-authored two books: Bumble Bees of North America: An Identification Guide (Princeton University,) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday). He published more than 50 percent of his papers following his retirement.

Leal, a leading global scientist and inventor in the field of insect olfaction and communication, is known for his impact in the fields of molecular, cellular biology and entomology.A member of RES since 2008, he was named a Fellow of RES in 2009 and Honorary Fellow in 2015.
The organization, founded in 1833 in London, is devoted to the understanding and development of insect science, and supporting international collaboration, research and publication. It aims “to show every person how remarkable and valuable insects are,” RES officials said.
Leal said he plans to “hone in on new ways to develop and promote diversity and inclusivity,” and “to see our global entomological community bud, bloom and flourish.”
Leal, who joined the UC Davis entomology faculty in 2000, chaired the UC Davis Department of Entomology in 2006-2008 before accepting a position in 2013 as professor of biochemistry in the Department of Molecular and Cellular Biology. He chairs the Council of the International Congresses of Entomology, the body that ensures the continuity of the international congresses of entomology, succeeding May Berenbaum of the University of Illinois Urbana-Champaign.
“As a citizen of the world--born in Brazil, educated in Brazil and Japan, and honored as a Distinguished Professor with the University of California, Davis---I am eager to be serve as a trustee of the Royal Entomological Society and be part of the RES strategic plan to (1) move insect science forward internationally, (2) empower the global entomological community, and (3) to promote diversity and inclusivity,” Leal said.
His peers praise him for his contributions to insect science, including his teachings (he has taught insect physiology for almost 15 years); his internationally recognized research for his pioneering and innovative work in insect olfaction and communication; his publication record; his global entomological leadership; his administrative positions; and his commitment to serving humanity and engaging with scientists from all over the world.
Leal, named a UC Davis Distinguished Professor in 2016, co-chaired the 2016 International Congress of Entomology in Orlando, Fla., one of entomology's most prominent events (6,682 registrants from 102 countries).
He is a Fellow of the Entomological Society of America (2009), American Association for the Advancement of Science (2005), and the National Academy of Inventors (2019). He served as president of the International Society of Chemical Ecology, among other leadership activities.
During the COVID pandemic, Leal brought together the entomological and chemical ecology communities through various creative activities, including inventing and organizing a symposium, “Insect Olfaction and Taste in 24 Hours Around the Globe,” drawing thousands of participants from nearly 60 countries. He provided a platform for young scholars to highlight their recent work and interact with well-established scholars in the field.
Leal received his Ph.D. in applied biochemistry from the University of Tsukuba, Japan, with subsequent postdoctoral training in entomology and chemical ecology at the National Institute of Sericultural and Entomological Science and Cornell University, respectively. He was the first non-Japanese person to earn tenure at Japan's Ministry of Agriculture, Forestry, and Fisheries.
UC Davis and RES are closely connected. Peter Cranston, emeritus professor, UC Davis Department of Entomology and Nematology, became an Honorary Fellow of RES in 2010. Among the RES Fellows are emeriti professors Frank Zalom (a past president of the Entomological Society of America) and Phil Ward, both of the UC Davis Department of Entomology and Nematology, and Art Shapiro, emeritus professor, Department of Evolution and Ecology.
As of October 2018, there are approximately 1,689 living Fellows, Foreign and Honorary Members, of whom 85 are Nobel Laureates, according to Wikipedia. Among the notables are Sir David Attenborough, Honorary Fellow; and Charles Darwin, and Albert Einstein, Fellows. RES Fellowship has been described by The Guardian as "the equivalent of a lifetime achievement Oscar."
