His lecture is from 4:10 to 5 p.m., Wednesday, Sept. 26 in 122 Briggs Hall, announced seminar coordinator Geoffrey Attardo, assistant professor and medical entomologist, UC Davis Department of Entomology and Nematology.
Hoddle, an Extension specialist, received his bachelor's degree (1988) and master's degree (1991) in zoology from the University of Auckland, New Zealand. He holds a doctorate in entomology (1996) from the University of Massachusetts, Amherst.
Since 1997, Hoddle has focused his research on biological control as a tool to reduce the impact of invasive pest species to agriculture, urban and natural areas, with a primary focus on issues affecting California. These programs, he says, often require long periods of overseas research in the home range of the target pest and searching for and studying natural enemies for possible use in biological control.
Hoddle received the Entomological Society of America's "Recognition Award in Entomology" in 2007, after earlier winning the the Pacific Branch of ESA award.
All seminars will take place on Wednesdays at 4:10 in 122 Briggs Hall, located on Kleiber Hall Drive.

Ella Mae Noffsinger, 84, who retired in 1991 as the senior museum scientist in charge of the UC Davis Nematode Collection, passed away March 22, 2018 in Woodland. She was a longtime resident of Palm Gardens Assisted Living, Woodland.
Noffsinger was instrumental in the development of the nematode collection, and collaborated with many nematologists in the description of species, said Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. Active in the Society of Nematologists (SOM) when few women were participating, she served on the SOM executive board and as the editor of the Nematology Newsletter, as well as numerous other committees.
During her career, her research and work took her from Colorado to Wisconsin to Chile: from the Beet Sugar Development Foundation in Fort Collins, to the University of Wisconsin, in Madison, and to Santiago, Chile, from 1967 to 1969. She worked with UC Davis nematologist M. W. Allen for many years.
A native of Center, Colo., she was born into the rural ranching family of Doc and Ruth Noffsinger on March 15, 1934. She received her bachelor's degree at what is now Colorado State University, and her master's degree in 1958 from California State University in zoology.
After retiring, she spent most of her time along the coast of Brookings, Ore., enjoying fishing, and other coastal pursuits. She is preceded in death by her parents and brothers. Survivors include her many nieces and nephews, as well as her close friends in the Woodland and Davis area.
Memorial donations may be made to the Salvation Army, "or the charity of your choice," her family indicated.
History of Nematology at UC Davis
Ecologist Louie Yang, associate professor of entomology, UC Davis Department of Entomology and Nematology, is the recipient of a major academic advising award.
NACADA, also known as the Global Community for Academic Advising, singled him out as the winner of the Faculty Advisor Award of Excellence in Pacific Region 9, comprised of California, Nevada and Hawaii.
Yang will be honored at the Pacific Region 9 meeting set for March 21-23 in Santa Rosa. NCADA promotes students' success by advancing the field of academic advising globally.
"Dr. Yang excels in fostering creative and critical thinking, challenging his students to succeed by linking their academic studies to research and other career goals," said Steve Nadler, professor and chair of the UC Davis Department of Entomolgy and Nematology. "His mentees not only include undergraduate and graduate students, but high school students and postdoctoral scholars and beyond. He attends to the unique needs and interests of each student, respecting their perspectives and ideas. Mentorship, he finds, is really about helping students identify the questions that they want to ask. His success is their success."
An important part of his advising is his work in the Research Scholars Program in Insect Biology (RSPIB), a campuswide program co-founded by Jay Rosenheim, Joanna Chiu and Yang. Aware that some of the most important skills for research biologists cannot be taught in big lecture halls or even in lab courses, they set out to help students learn cutting-edge research through close mentoring relationships with faculty. The program crosses numerous biological fields, including population biology; behavior and ecology; biodiversity and evolutionary ecology; agroecology; genetics and molecular biology; biochemistry and physiology; entomology; and cell biology. The goal? To provide academically strong and highly motivated undergraduates with a multi-year research experience that cultivates skills that will prepare them for a career in biological research.
In addition to RSPIB mentoring, Yang mentors many undergraduates in his lab. He has welcomed and mentored students from UC Davis and from around the country with the National Science Foundation Research Experiences for Undergraduates Program (Natalie Gonzalez and Jacob Penner) and the UC Davis-Howard University Historically Black Colleges and Universities (HBCU) Ecology & Evolution Graduate Admissions Pathways (EEGAP) program (Kabian Ritter).
In the past year, Yang mentored 15 undergrads in his lab in studies that included: the nonconsumptive effects on monarch development to see if parasitoid avoidance behaviors in early development have a long-term cost for monarch development; the factors that contribute to herbivory by generalist herbivores on milkweed;the effects of a recently observed plant foliar fungal pathogen on milkweed on monarch growth and development; the costs of switching milkweed species for monarch larvae; and the density dependence in larval and adult blue milkweed beetles
Yang, who joined the UC Davis faculty in 2009, teaches Insect Ecology and Field Ecology. He holds a bachelor's degree (ecology and evolution) from Cornell University, 1999 and received his doctorate from UC Davis in 2006. His goals as an advisor are three-fold:
- To be honest to the unique needs and interests of each student. "I aim to assess the advising needs of each student individually, recognizing that these needs can change quickly. I listen and watch, try not to make too many assumptions, and remind myself to expect the unexpected. Science is a human endeavor, and the same diversity of ideas and perspectives that fuels scientific progress means that each scientist needs different advising to succeed. In many cases, I have found that the primary task of mentorship is helping students identify the questions that they want to ask. I seek to respect each student's unique perspective and interests, and to believe what they say."
- To facilitate intellectual independence. "My aim is to help students transition from being consumers of knowledge to becoming producers of knowledge. This transition requires giving students the intellectual freedom to learn from their own decisions. I aim to maintain appropriate humility when I provide advice; when working at the limits of available knowledge, I believe that we usually recognize the best decisions only in hindsight, and the best outcomes often result from a willingness to capitalize on unexpected events. As a research advisor, I am committed to the long-term success of each student, but encourage students to exercise their intellectual courage and curiosity, even at the risk of short-term failures. We develop as scientists by making our own mistakes, and using those mistakes to improve our judgment. I remind myself allow enough gaps in my advising to allow students to learn first from their interactions with nature.
- To learn from his students. "I believe that mentorship should be a two-way street, and I expect my students to develop the knowledge and confidence to teach me things that I don't know. As scientists, we are motivated by learning new things, and this is a model of advising that is intellectually engaging and sustainable over the long-term. More importantly, it gives my students the opportunity to become experts and teachers, and to view themselves as intellectual colleagues and contributors."
Former student Allyson Earl, now a researcher in Guam, credits Yang with shaping her academic career: "I had the pleasure of working under Louie Yang for the last year of my undergraduate degree at UC Davis as one of his research assistants. I watched as he worked tirelessly with several other student assistants in the lab on personal projects focused on our study subjects, Monarch butterflies. His mentorship style in these projects was one that guided students to draw their own conclusions rather than handing them answers, leading them to ask more complex questions and develop themselves as better students and scientists. I can say with confidence, he not only nurtured my desire to study the intricacies of ecology, but also to pursue a career in this field, without his guidance and support I would not be where I am today."
Yang also launched the Monitoring Milkweed-Monarch Interactions for Learning and Conservation (MMMILC) Project in 2013 for high school students in the environmental science program at Davis Senior High School or those associated with the Center for Land-Based Learning's GreenCorps program. They monitor milkweed-monarch interactions in a project funded by the National Science Foundation. Yang and UC Davis undergraduate and graduate students serve as mentors.
Yang strongly supports student diversity, under-represented groups, and graduate education. Two of his undergrads, including one Latina, were supported by a supplemental Research Experiences for Undergraduates (REU). He has mentored graduate students from the Entomology Graduate Group, the Graduate Group in Ecology and the Population Biology Graduate Group. He serves on many guidance, exam and advising committees. He also has participated in mentoring workshops at the Center for Population Biology.
Yang earlier was selected faculty recipient of the 2017 Eleanor and Harry Walker Academic Advising Award from the College of Agricultural and Environmental Sciences (CA&ES).
Sue Ebeler, associate dean of Undergraduate Academic Programs, College of Agricultural and Environmental Sciences, praised Yang's focus on student diversity, his efforts in helping students link their academic studies to research and other career goals, and his innovative programs working with high school students and connecting these students with undergraduate and graduate student mentors.
The Associated Students of UC Davis nominated him for an Excellence in Education Award in 2012. He received a prestigious National Science Foundation Faculty Early Career Development Award of $600,000 in 2013.
His abstract: "His abstract: "Plant infections by root-knot nematodes and the soil-borne fungal pathogen Fusarium oxysporum, which causes vascular wilt, either alone or in disease complexes, result in serious crop losses. Our analyses of host resistance in cowpea and cotton genomes has revealed a rich resource of resistance factors to both pathogens, which are being used in breeding programs for crop improvement."
Of his research, Roberts says: "My research focuses on the integrated management of plant parasitic nematodes. A major emphasis is placed on the identification, characterization, and development of host plant resistance to root-knot nematodes for genetic improvement of crops. Current work includes studies of resistance gene inheritance, development of gene markers, genome mapping, and gene transfer."
He organizes his research on the genetic resistance and associated traits in crop plants to root-knot nematodes in the areas of:
- identifying new sources of resistance genes;
- nature, inheritance and molecular characterization of resistance genes;
- introgressing resistance for breeding line and crop improvement for warm/arid environments using classical and novel techniques;
- assessing and implementing resistant and tolerant lines and cultivars in the field in appropriate cropping systems; and
- studying variability of parasitic specificity within and between nematode species
Host is Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. This is the department's last seminar of the fall quarter.
The event, free and open to the public and family friendly, is an annual open house focusing on parasitoids.
"An insect parasitoid is a species whose immatures live off of an insect host, often eating it from the inside out," said Tabatha Yang, education and outreach coordinator of the Bohart Museum. "It is part of their life cycle and the host generally dies."
Among the presentations or topics:
- Bohart Museum senior museum scientist Steve Heydon, a world authority on Pteromalids, or jewel wasps, a group of tiny parasitoids.
- Entomology PhD student Jessica Gillung who researches the Acroceridae family "a remarkable group of endoparasitoids of spiders."
- Diagnostic parasitologist Lauren Camp of the UC Davis Veterinary Medical Teaching Hospital, is an authority on nematodes.
- Family craft activity is a pop-up card, featuring a monarch chrysalis and a fly, suitable for mailing to friends and family during the holiday season.
There are some 3,450 described species of Pteromalids, found throughout the world and in virtually all habitats. Many are important as biological control agents.
Members of the Acroceridae are "rare and elusive flies lay the eggs on the ground or vegetation, and the little larva is in charge of finding itself a suitable host," Gillung said. "Upon finding the host, the larva enters its body and feeds inside until it's mature to come outside and pupate. They eat everything from the spider; nothing is wasted."
Lauren Camp, who received her doctorate from UC Davis, studying with major professor Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology, will display a variety of nematodes amd answer questions.
She describes nematodes in one word as "worms" and in expanding, “Nematodes are an amazing phylum of organisms--they exist in almost every known environment on the planet, and different species eat everything from bacteria and fungi to plant and animal tissue."
Tachinid flies, which lay their eggs in caterpillars and chrysalids, will be on display, along with the remains of its hosts. It is used as a biological control agent for some pests. But those who rear monarch butterflies consider it their enemy when it lays eggs in their caterpillars and chrysalids.
The late UC Davis entomologist Richard M. Bohart (1913-2007) researched Strepsiptera, or twisted-wing parasites, for his doctorate in 1938. Both the Bohart Museum and an entire family of Strepsiptera, the Bohartillidae, are named in honor of Professor Bohart.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks, praying mantids and tarantulas. Visitors are invited to hold some of the insects and photograph them. The museum's gift shop, open year around, includes T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
The Bohart Museum holds special open houses throughout the academic year. Its regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free.
