This year's recipient is Marc Tatar, an authority on the aging of insects.
Tatar, a professor in the Division of Biology and Medicine at Brown State University, Providence, R.I., will speak on “Integrated Control of Drosophila Aging by Insulin/IGF (Insulin-Like Growth Factor) Signaling” at 6:15 p.m. Wednesday, Dec. 5 in Ballroom A of the Activities and Recreation Center (ARC), UC Davis campus. Prior to the presentation, a wine and cheese reception will take place from 5 to 6 p.m. outside of Ballroom A.
The event is open to all interested persons, said James R. Carey, UC Davis professor of entomology, who will introduce his former student. The presentation will be recorded for later posting on the UCTV seminars.
Tatar has studied the demography, evolution and genetics of aging working with a variety of insect systems to explore the regulation and basic mechanisms of life history traits and senescence. The current work in the Tatar laboratory focuses on genetic analysis of Drosophila to understand how insulin/IGF signals and lipid hormones regulate aging, and how these endocrine signals interact with nutrition.
Tatar received his doctorate in ecology from UC Davis in 1994 while with the Graduate Group in Ecology, working in James Carey's laboratory. Tatar obtained his bachelor’s degree in biology in 1980 from Earlham College, Richmond, Ind., and went on to receive his master’s degree in zoology from UC Davis in 1984. He completed postdoctoral research in genetics at the University of Minnesota, St. Paul before joining the Brown University faculty in 1997. He was promoted to professor in 2007.
While at UC Davis, Tatar was the 1994 recipient of the Merton Love Award for his Outstanding Dissertation in Ecology and Evolution. He is an Ellison Senior Scholar, founding joint editor-in-chief of the journal Aging Cell, and a past member of the Board of Review Editors for Science.
The Leigh seminar memorializes cotton entomologist Thomas Frances Leigh (1923-1993), an international authority on the biology, ecology and management of arthropod pests affecting cotton production. During his 37-year UC Davis career, Leigh was based at the Shafter Research and Extension Center, also known as the U.S. Cotton Research Station. He researched pest and beneficial arthropod management in cotton fields, and host plant resistance in cotton to insects, mites, nematodes and diseases.
Leigh, who joined the UC Davis Department of Entomology in 1958, retired in 1991 as an emeritus professor, but he continued to remain active in his research and collaboration until his death on Oct. 26, 1993.
At Shafter, Leigh focused his research on the biology, ecology, host plant resistance, control and management of insects and spider mites on cotton. He stood at the forefront of Integrated Pest Management (IPM) of cotton pests, according to an article in the summer 1994 edition of American Entomologist. He taught courses on cotton IPM and host plant resistance.
In his memory, his family and associates set up the Leigh Distinguished Alumni Seminar Entomology Fund at the UC Davis Department of Entomology. When his wife, Nina, died in 2002, the alumni seminar became known as the Thomas and Nina Distinguished Alumni Seminar.
Thanks to the Leigh family, outstanding UC Davis alumni return to campus to share their accomplishments.
Professor Marc Tatar of Brown State University, Providence, R.I., will deliver the Thomas and Nina Leigh Distinguished Alumni Seminar at UC Davis on Dec. 5.
Those are some of the topics to be covered at the UC Davis Department of Entomology's fall noonhour seminars, to begin Wednesday, Oct. 17 and continue through Wednesday, Nov. 28 in Room 1022 of the Life Sciences Building.
All seminars will be held every Wednesday except for Nov. 14. No seminar will be held that day. That's during the Entomological Society of America's annual meeting, which will take place Nov. 11-14 in Knoxville, Tenn.
The good news is that if you cannot attend these seminars, not to worry. Professor James R. Carey is arranging the videotaping of the seminars. They will be be broadcast at a later date on UCTV. Meanwhile, if you missed any of the previous ones, most can be accessed on UCTV.

The first speaker, evolutionary biologist Tim Linksvayer, will focus on superorganisms. Honey bees are considered superorganisms.
"Despite these conspicuous superorganismal properties and the inherent hierarchical organization of life in insect societies (i.e. colony-level, organismal-level), most previous studies of the evolutionary genetic and molecular basis of social insect traits use the same reductionist approaches that have been developed for solitary organisms, where an individual’s traits are only influenced by its own genome. More realistically, in social organisms, an individual’s traits are the property of the genomes of all social group members. I will discuss ongoing integrative research studying how social interactions in ants and honey bees affect the expression and evolution of individual- and group-level traits."

James R. Carey, professor of entomology at the UC Davis Department of Entomology (the department co-sponsored the event), webcast the six talks presented by either current or retired UC Davis professors. The videos are now on UCTV; here's the link to the Honey! index page.
Did we say "free?" Free.
Carey is a firm believer that UC seminars ought to be shared with not only UC affiliates but with the general public. (Read about how and why he spearheaded the 10-campus project.)
Meanwhile, you can learn about bees from some of the country's best: two UC Davis Department of Entomology faculty and one emeritus. Extension apiculturist Eric Mussen discussed "The Wonder of Honey Bees" and later presented a talk about honey and honey tasting.
Assistant professor Brian Johnson--he researches the behavior, evolution, and genetics of honey bees--covered "Honey Bee Communication: How Bees Use Teamwork to Make Honey" and emeritus professor Norman Gary, a scientist, author and professional bee wrangler, convinced us why we should consider "Hobby Beekeeping in Urban Environments." After all, he's been keeping bees for 64 years!
Then Louis Grivetti, professor emeritus in the nutrition department, strode to the podium to tell us "Historical Uses of Honey as Food"--you won't believe all the things he said in his well-researched talk! Liz Applegate, nutrition professor and director of the Sport Nutrition Program," followed with "Sweet Success: Honey for Better Health and Performance."
By the end of the day, the crowd agreed with Mussen that “Honey bees are truly marvelous.” And with Johnson who pointed out: “Bees have small brains but can solve big problems."
A nice addition: a honey-tasting contest judged by the attendees. The winner? An oh-so-good clover honey from Sacramento Beekeeping Supplies. The honey (yes, it's available for sale at the 2110 X St. business), was produced by the Jones Bee Company, Salt Lake City. Second place went to Alan Pryor of Alameda; and third place, Diane Kriletich of Paloma, Calaveras County.
“It was a sweet day all in all,” said coordinator Clare Hasler-Lewis, executive director of RMI.
Indeed it was!

Dengue is one of them.
Dengue, transmitted by the daybiting Aedes aegypti mosquito, globally infects 50 to 100 million people yearly, according to dengue expert Tom Scott, professor of entomology at UC Davis. At risk are some 2.5 to 3 billion people, primarily in tropical and sub-tropical countries. The most severe form of the disease, dengue haemorrhagic fever (DHF), strikes half a million a year and kills an estimated 5 percent, according to the Centers for Disease Control and Prevention.
Those alarming statistics are why scientists like Scott and Kathryn “Kathy” Hanley devote their lives to studying the emergence and control of dengue.
Hanley will speak on “Fevers from the Forest: Dynamics of Sylvatic Dengue Virus and Chikungunya Virus in their Primate Hosts and Mosquito Vectors in Southeastern Senegal from 12:10 to 1 p.m., Wednesday, Nov. 30 in 122 Briggs Hall.
Scott will introduce Hanley, an associate professor at New Mexico State University, Las Cruces, and now on sabbatical (she's working in the Scott lab).
The Hanley lab investigates the molecular biology, evolution and ecology of emerging RNA viruses like dengue and influenza, with the goal of using this basic knowledge to design better methods to control the spread of these dangerous pathogens.
Abstract of Her Talk:
"Mosquito-borne dengue virus exists in two ecologically and evolutionarily distinct transmission cycles: an ancestral sylvatic cycle in which the virus is transmitted between non-human primates and arboreal Aedes, and a derived human cycle in which the virus is transmitted by domestic and peridomestic Aedes, primarily Ae. aegypti. This seminar will present current research on the evolutionary and ecological factors that promote, and constrain, the emergence of sylvatic dengue virus into transmission among humans."--Kathryn Hanley.
Kathryn Hanley, who joined New Mexico State University as an assistant professor of biology in 2004 and was promoted to associate professor in 2010, says she is a proud native of New Jersey, and "yes, I stand by that statement." She received her bachelor of arts degree from Amherst College where she majored in biology and minored in English poetry. After graduating magna cum laude, she entered a Ph.D. program at UC San Diego. Her dissertation research on host-parasite interactions in parthenogenetic lizard species involved fieldwork across the islands of the South Pacific. Hanley received her Ph.D in biology in 1994, and subsequently conducted postdoctoral research at UC Davis, the University of Maryland and the National Institutes of Health (NIH).
She credits NIH for initiating her investigation of the emergence and control of dengue virus that remains the focus of her research today.
The Scott lab was recently featured on National Public Radio. The lab's research on daily temperature fluctuations drew international attention last April when the Proceedings of the National Academy of Sciences published that work. The research, Scott said, helped explain why dengue increases during certain times of the year in “tropical areas where mosquito-borne diseases inflict an enormous burden on human health."
If you miss Hanley's lecture, you can probably view it on UCTV. Professor James R. Carey is recording research seminars and posting them on UCTV.

Bugs do rule, and they'll rule at the 59th annual meeting of the Entomological Society of America (ESA), to take place Nov. 13-16 in the Reno-Sparks Convention Center, Reno.
At the event, the UC Davis Department of Entomology will be one of the most honored departments in its history.
Professor Frank Zalom, in line for the presidency of the 6000-member association, will be installed as vice president-elect and will begin his term Nov. 16. Professor James R. Carey and Diane Ullman, professor and associate dean for undergraduate academic programs in the College of Agricultural and Environmental Sciences, will be inducted as ESA fellows, an honor limited to 10 persons per year.
Michael Parrella, professor and chair of the Department of Entomology, will receive the Distinguished Achievement Award in Horticultural Entomology, and professor Walter Leal, the Nan-Yao Su Award for Innovation and Creativity in Entomology.
Harry Kaya, emeritus professor of entomology and nematology, will be honored at a special seminar titled “Entomopathogenic Nematodes: Their Biology, Ecology, and Application. A Tribute to the Dynamic Career of Harry K. Kaya.” Ed Lewis, acting chair of the UC Davis Department of Entomology, is among the coordinators.
Three other faculty members are moderating/organizing or co-conducting symposiums. They are James R. Carey, “Insect Demography: Emerging concepts and Applications”; Neal Williams, “Biodiversity, Global Change and Insect-Mediated Ecosystem Services,” and Walter Leal, “Insect Olfaction and Taste: Identifying, Clarifying and Speaking about the Key Issues.” Each will also deliver a lecture.
Leal and Parrella are among the most active UC Davis members of ESA. Leal is serving on the Presidential Committee on the International Congress of Entomology (ICE), to be held Aug. 19-25 in Daegu, South Korea. Parrella holds a seat on the ESA Governing Board, representing the Pacific Branch of the ESA.
Graduate students will also be quite involved at the ESA meeting. The UC Davis Linnaean Team will participate in the annual competition. The team includes Matan Shelomi, who studies with major professor Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology; Meredith Cenzer, who studies with Louie Yang; Andrew Merwin, who studies with Michael Parrella; Mohammad-Amir Aghaee, who studies with Larry Godfrey; and Hanayo Arimoto, with studies with Ed Lewis. The team earlier won first place in the Pacific Branch competition.
Another highlight is a student debate: “Identify...Clarify...Speak Out! Land Grant Mission, Organic Agriculture & Host Plant Resistance Programs.” UC Davis entomology graduate students will team to argue the pro side: Matan Shelomi, Mohammad-Amir Aghaee; Andrew Merwin; Meredith Cenzer, and Kelly Hamby (she studies with major professor Frank Zalom).
There's also the fun side. A video created by UC Davis undergraduate student Heather Wilson, who works in the Frank Zalom lab, is entered in the open division category of the ESA YouTube Contest. Her entry, “I Wanna Be an Entomologist,” is a a parody of the hit song, “I Wanna Be a Billionaire.” Wilson filmed the video in the Zalom lab and the Bohart Museum of Entomology. On the serious side, she'll present her research on the Spotted Wing Drosophila: “Seasonal Movements of Drosophila suzukii (Diptera: Drosophilidae) in a Multi-Crop Setting.” Watch Heather Wilson's video
In addition, scores of other UC Davis representatives--faculty, graduate students and postdoctoral scholars--will present their work.
Yes, bugs do rule!
