Her colleague, ESA president Frank Zalom, a distinguished professor in the UC Davis Department of Entomology and Nematology, presented the award at the organization's recent meeting in Portland, Ore.
This is the highest honor that the 7000-member ESA presents to its outstanding teachers.
Ullman chaired the UC Davis Department of Entomology in 2004-2005, and served as an associate dean for undergraduate academic programs, College of Agricultural and Environmental Sciences from 2005 to 2014. There she led curriculum and program development, student recruitment and outreach, and she administrated all undergraduate academic activities.
Ullman is known for innovative, multidisciplinary teaching strategies that connect science and art programs that mentor the next generation of scientists and help undergraduates succeed. Key examples are the Art/Science Fusion Program (using experiential learning to enhance scientific literacy), the Career Discovery Group Program (training mentors to help students explore careers and select majors), and the national Thrips-Tospovirus Educational Network (training graduate students and postdoctoral scholars to mentor new scientists).
Ullman's research revolves around insects that transmit plant pathogens, in particular plant viruses. She is best known for advancing international knowledge of interactions between thrips and tospoviruses and aphids and citrus tristeza virus. Her contributions have played a fundamental role in developing novel strategies for management of insects and plant viruses. She leads a $3.75 million Coordinated Agricultural Project, and has authored more than 100 refereed publications.
Highly honored for her work, Ullman is a fellow of the American Association for the Advancement of Science (2014) and ESA (2011). Among her many honors: the USDA Higher Education Western Regional Award for Excellence in College and University Teaching (1993), the UC Davis Chancellor's Achievement Award for Diversity and Community (2008), and the 2014 Distinguished Award in Teaching from ESA's Pacific Branch.
Ullman received her bachelor's degree in horticulture from the University of Arizona in 1976 and her doctorate in entomology from UC Davis in 1985. She began her career in 1987 at the University of Hawaii-Manoa, relocating in 1995 to UC Davis' Department of Entomology and Nematology. Ullman also holds a joint appointment with the graduate programs of the Department of Entomology and Nematology, and the Department of Plant Pathology.
“Dr. Ullman is a world-renowned and highly respected teacher, but she is an outstanding mentor, researcher and administrator who combines innovation, energy, talent and dedication to help students learn, retain that knowledge, and succeed in class, college and life. They cannot praise her enough, and neither can we,” the nominating team wrote.

Dingle, a UC Davis emeritus professor of entomology and author of two editions of “Migration: The Biology of Life on the Move,” said his previous studies reveal that migrant and resident monarchs exhibit different wing shapes.
Dingle is the recipient of the UC Davis Edward A. Dickson Professorship Award to research “Monarchs in the Pacific: Is Contemporary Evolution Occurring on Isolated Islands?”
Dingle will be working with community ecologist Louie Yang and molecular geneticist Joanna Chiu, assistant professors in the UC Davis Department of Entomology and Nematology, to examine the ecology and physiology of monarch butterflies (Danaus plexippus) in three islands where contemporary evolution might be expected. The islands are Oahu (Hawaii), Guam (Marianas) and Weno (Chuuk or Truk).
“This is the necessary first step in a long-term analysis of the evolutionary ecology and physiology of monarch butterflies on remote Pacific islands,” said Dingle, a fellow of the American Association for the Advancement of Science and the Animal Behavior Society.
Dingle said the monarch, widely distributed “for eons” in the New World, is fairly new to the Pacific islands and to Australia. “In addition to North America, the monarch occurs as a resident throughout the Caribbean and Central and northern South America—and probably as a migrant farther south. One of the more intriguing aspects of its distribution is that beginning in the early part of the 19th century, it spread throughout the Pacific all the way to Australia, where there are now well-established migratory and non-migratory populations.”
Dingle speculates that the monarchs arrived in the Pacific islands with their host plant, milkweed, which was valued at the time for its medicinal properties. Some of the islands are extremely isolated, he said.
An analysis of a monarch population in Hawaii shows that resident monarchs have shorter, broader wings than the long-distance migrants. The Hawaii butterfly wings were shorter than the eastern U.S. long-distance migrants, but “not so short-winged as the residents in the Caribbean or Costa Rica, which have been present in those locations for eons, rather than the 200 years for Hawaii.”
“If there are indeed wing shape changes associated with evolution in isolation, are there other changes that may have occurred under selection and local adaptation for residency?” Dingle wonders. “Are there other changes that may have occurred under selection and local adaptation for residency? Examples of such traits might be changes in flight muscle physiology, changes in photoperiodic diapause response, changes in the characteristics of orientation ability and its relation to antennal circadian rhythms, or changes in the reproductive capacity or tactics (re-colonization of ‘empty' habitats is no longer part of the life cycle).
“Diapause and fat storage, necessary to support migration, are triggered by short photoperiods,” Dingle said, “and the butterflies orient using a sun compass synchronized to a circadian rhythm in the antennae. Overwintering sites in North America include the Transvolcanics Mountains of central Mexico, and the California Coast, particularly Santa Cruz, Pismo Beach, and Pacific Grove.
The UC Davis team will study the monarchs on the three islands and compare them with California mainland monarchs. Using an image analyzer and camera equipment available in Yang lab, the team will photograph “chilled” butterflies in a fixed position with wings spread and then release them back into the wild. The image analyzer will measure different variables, including length, width and angles from the photographs and compute multivariate-shape parameters.
The Chiu lab will assess genetic differences using a transcriptomic approach with monarch caterpillars. “This assessment will be greatly facilitated by the fact that the monarch genome has now been sequenced,” Dingle noted. “A major focus of Dr. Chiu's research is circadian rhythm genes, and these will be especially relevant here because of the association of these genes with monarch capabilities. Because the monarch cell line is cycling and has a functional circadian clock, effects of mutations in specific clock genes can be examined with regard to clock function.”
Dingle expects the one-year research program not only to form the basis for “long-term research on the evolutionary genetics of behavior, ecology and physiology on Pacific island monarch butterflies” but on “the general aspects of island biogeography, a subject of great practical theoretical interest in evolutionary biology.”
Both Yang and Chui currently have grants involving research on monarch butterflies. Yang also studies island ecology.
Dingle, who received his bachelor's degree in zoology from Cornell University and his doctorate in zoology from the University of Michigan, served on the faculty of the UC Davis Department of Entomology (now the UC Davis Department of Entomology and Nematology) from 1982 to 2002 and achieved emeritus status in 2003. He is a past president of the Animal Behavior Society and former secretary of the International Society for Behavioral Ecology.
Dingle published the second edition of “Migration: The Biology of Life on the Move” (Oxford University Press) in November 2014. It is the sequel to the widely acclaimed first edition, published in 1996. National Geographic featured Dingle in its cover story on “Great Migrations” in November 2010. LiveScience interviewed him for its November 2010 piece on “Why Do Animals Migrate?”
Dingle was interviewed recently by Italian journalist Giovanna Faggionato for a piece on migration in the Pirelli magazine.

Ullman, elected to the Section on Agriculture, Food, and Renewable Resources, focuses her research on the interactions among insects, viruses and plants. She also studies the development of strategies for managing disease-causing microorganisms that are transmitted to plants by insects.
Earlier this month she received the 7000-member Entomological Society of America's distinguished achievement award in teaching at ESA's meeting in Portland, Ore.
AAAS will present each of the 401 new fellows in the Class of 2014 with a certificate and gold-and-blue rosette pin on Saturday, Feb. 14, during the association's annual meeting, to be held in San Jose. UC Davis now has a total of 152 AAAS fellows.
Ullman is the former associate dean for undergraduate academic programs, College of Agricultural and Environmental Sciences, and is the co-founder and co-director of the UC Davis Art/Science Fusion Program.
Highly honored for her work, Ullman was named a fellow of ESA in 2011. She received the UC Davis Chancellor's Achievement Award for Diversity and Community in 2008; the USDA Higher Education Western Regional Award for Excellence in College and University Teaching in 1993; and the Hawaiian Entomology Society Entomologist of the Year Award in 1992, among her many awards.
Ullman joined the UC Davis Department of Entomology (now Entomology and Nematology) in 1995. She served as the department's vice chair from 2001 to 2004, and as the 2004-05 chair. Ullman obtained her bachelor's degree in horticulture from the University of Arizona, Tucson, in 1997 and her doctorate in entomology from UC Davis in 1985.
Ullman is one of 11 fellows from the UC Davis Department of Entomology (now the UC Davis Department of Entomology and Nematology) since 1976. Two have since joined other departments and one is deceased. They are:
- Distinguished Professor James Carey, elected in 2011

Spotlight on Danny Klittich
Klittich, who is starting his third year as a doctoral student in the UC Davis Department of Entomology and Nematology, studies with major professor Michael Parrella, professor and chair of the department.
The T-shirt, publicly available for purchase, with proceeds benefitting EGSA, is golden yellow with a black illustration. Graduate student and T-shirt project coordinator Margaret “Rei” Scampavia is taking orders at m.rei.scampavia@gmail.com. Sizes range from youth small to adult double X.
Klittich says he's not an artist but has always had an interest in honey bees. He was a member of the UC Davis graduate student team that won the student debate championship, Nov. 18, at the Entomological Society of America's 62nd annual meeting in Portland, Ore. The team debated neonicotinoids, defeating Auburn (Alabama) University team. UC Davis successfully argued the con side of “Neonicotinoids Are Causing the Death of Bees Essential for Pollinating our Food Crops. The Use of Neonicotinoids Should End.” The team, captained by Mohammad-Amir Aghaee of the Larry Godfrey lab, also included Jenny Carlson, Anthony Cornel lab; Ralph Washington Jr., Steve Nadler lab; Margaret "Rei" Scampavia, Neal Williams/Edwin Lewis lab.
Klittich, from Fillmore, is a graduate of Fillmore High School and valedictorian of the Class of 2006. He grew up in the nursery business, working at his family's nursery, Otto and Sons Nursery, Inc., Fillmore. During his youth he was active in 4-H and Boy Scouts, achieving the rank of Eagle Scout.
Klittich plans to receive his doctorate in 2016. His career goal: to pursue a career in pesticide and IPM research either in the private sector or in the California University System as a farm advisor.
In addition to the honey bee t-shirt, EGSA is offering other T-shirts, most available for $15. Popular EGSA shirts depict a dung beetle, “They See Me Rollin'”; a “cuddling moth” for infants and toddlers; a weevil shirt, “See No Weevil, Hear No Weevil, Speak No Weevil”; and “The Beetles” shirt, of four beetles crossing Abbey Road, reminiscent of The Beatles pictured on their Abbey Road album. All can be ordered from Margaret “Rei” Scampavia at m.rei.scampavia@gmail.co.
