Lewis is recognized as a global leader in using nematodes as biological agents, said nematologist Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology.
Lewis will receive the award at PBESA's 100th annual meeting, “Science for the Next Century,” set April 3-6 in Honolulu. PBESA is comprised of 11 western states: Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, Oregon, Utah, Washington, Wyoming), parts of Canada and Mexico, and seven U.S. territories.
Lewis is now an applicant for the national IPM award, to be presented by ESA at its September meeting in Orlando, Fla.
IPM specialist Frank Zalom, UC Davis distinguished professor of entomology and a past president of the 7000-member Entomological Society of America, praised “Ed's outstanding contributions to our state, national and global agricultural research.”
“Ed's work involves five of our state's 10 most valued commodities: almonds, a $5.9 billion crop, strawberries, $2.5 billion; walnuts, $1.8 billion; tomatoes, $1.6 billion and pistachios, $1.6 billion (2014 statistics),” said Zalom, a past recipient of the Pacific Branch and national IPM awards. “Also in 2014, California's agricultural exports amounted to $21.59 billion in value. Thus, in many respects, California feeds the world, and Ed's research is integral to controlling insects and nematodes.”
“Dr. Lewis has one of the most diversified research programs that I have known,” Nadler said. “He collaborates regularly with many different constituencies ranging from small startup companies to various commodity boards in order to take information from basic laboratory research and apply it to field situations. What ties together many of these projects is biological control of pest organisms with a focus on sustainability and integrated pest management.”
“Dr. Lewis' lab has been instrumental in using entomopathogenic nematodes (EPNs) to implement biological control of a large variety of insect pests,” Nadler pointed out. “His research with these nematodes has focused on investigating the ecological factors that relate to host-finding, persistence in soil, and their efficacy in field situations.”
In addition to understanding factors that influence nematode success, the Lewis laboratory “has worked to understand how other approaches, such as novel fertilizers, can work in combination to increase plant productivity,” Nadler said.
“Few scientists working with EPNs have designed and implemented such detailed and relevant studies to characterize what happens to nematodes under field conditions,” Nadler noted. “Importantly, use of EPNs to control naval orangeworm is effective and can reduce the need for pesticide applications.”
Research entomologist David Shapiro-Ilan of the USDA's Agricultural Research Service said that Lewis' research has “contributed immensely to the disciplines of entomology and IPM.”
“Dr. Lewis has clearly emerged as a world leader in research and application of entomopathogenic nematodes or EPNs,” said Shapiro-Ilan.
A native of New York, Lewis received his doctorate in entomology in 1991 from Auburn (Ala.) University and then accepted postdoctoral positions at Rutgers University and the University of Maryland. He then moved to Virginia Tech to join the entomology faculty there.
Lewis joined the UC Davis faculty in 2004. He serves as the editor-in-chief of the Elsevier journal Biological Control. He is also known for teaching two highly popular classes at UC Davis: “Behavioral Ecology of Insects” and “Biological Control of Agricultural Pests.”

It's a wasp on wheels.
A wasp riding a penny-farthing or a high wheel bicycle is the winner of the 2015 annual t-shirt contest sponsored by the Entomology Graduate Students' Association (EGSA) at the UC Davis Department of Entomology and Nematology.
“I wanted to draw a penny-farthing, which is part of the UC Davis culture,” said artist Stacey Rice, a junior specialist in the lab of Extension entomologist Larry Godfrey. “Then I wanted an insect that would be able to put its abdomen on the seat and have long enough legs to reach the pedals.”
She solved the dilemma by creating a “new species” of wasp and drawing the majority of votes from faculty, staff and students to win the annual contest. The result: “Hymenoptera on Bicycle.”
The t-shirt, now available to the public, went on sale at the Entomological Society of America meeting Nov. 15-18 in Minneapolis.
“I love the new design and think it translated very well on the t-shirts,” said EGSA treasurer and entomology graduate student Cindy Preto of the Frank Zalom lab. “ I expect it to be a great seller.”
In the Godfrey lab, Rice does research on Bagrada bugs (Bagrada hilaris), an invasive stink bug from Africa known for attacking cole crops, including broccoli, cabbage, collards, Brussels sprouts, cauliflower, kale, and mustard.
An alumnus of UC Davis, Rice received her bachelor's degree in biological sciences with a minor in veterinary entomology in March 2015. Her goal is to attend graduate school and receive her doctorate, either in integrated pest management or forensic entomology.
She became interested in both fields after enrolling in a “behavioral ecology of insects” course taught by Edwin Lewis, associate dean for agricultural sciences in the College of Agricultural and Environmental Sciences, and professor and former vice chair, UC Davis Department of Entomology and Nematology.
Rice, who grew up in Roseville and graduated from Oakmont High School, combines science with art. She enjoys creating ceramic art at the UC Davis Crafts Center.
EGSA has launched an online store where the newly designed t-shirt and other favorites can be ordered. For more information on the T-shirt, contact EGSA member Cindy Preto at crpreto@ucdavis.edu. All proceeds benefit EGSA.
It can be ordered in unisex heather navy with white lettering ($15 for small, medium, large, extra large and 2x); youth navy with white print ($15 for small, medium and large); and women's cut, heather red with light yellow print ($17 for small, medium and large).

Helene Dillard, dean of CA&ES, announced the appointments today (Oct. 9).
Lewis, representing the agricultural programs, joins Professor Ron Tjeerdema, Department of Environmental Toxicology, representing the environmental programs; and Cooperative Extension Specialist Dave Campbell, Department of Human Ecology, representing the human/social sciences programs.
The new leadership team will further develop our inter- and cross-disciplinary engagement among college and campus programs to enhance the mission of the college, Dillard said.
The new associate deans will serve five-year, 80 percent appointments that became effective Oct. 1, 2014.
They will report to and work collaboratively with CA&ES Executive Associate Dean Mary Delany on the planning and administrative coordination of departments and programs in the college.
In addition to working with department chairs on research and outreach, the associate deans also will work with Dean Helene Dillard to represent CA&ES to other colleges, schools, stakeholders, and visitors, and work with development staff to advance college fundraising objectives.
Current Associate Dean Jan Hopmans has agreed to stay on for the 2014 fall quarter transition.
Lewis joined the UC Davis faculty as an associate professor of nematology and entomology in 2004. He was promoted to professor in 2008.
Lewis is editor-in-chief of the prestigious Biological Control journal (as of July 1). He is a member of the Entomological Society of America, Society of Invertebrate Pathology, and the Society of Nematologists. His professional service includes subject editor of the Journal of Nematology and North American editor of Biopesticides International. He is a former chair of USDA Regional Project 1024.

"The average grocery store must dispose of more than 600 pounds of meats and produce every day when the products pass their sell-by date," Lewis says. "Where does it go? Currently, most waste food from groceries ends up in landfills. This costs grocery stores significantly, and wastes food and energy."
"A start-up company in this area, California Safe Soils LLC, is developing a novel solution to this problem by turning this wasted food into an agricultural product for soil nutrition. Nutrient management is a serious challenge to agriculture in California. Coupled with the need for providing the necessary nutrients to grow crops is the increasing concern of nitrate contamination of ground and surface water that comes from agricultural uses. A new product, called Harvest to Harvest, is in the testing phase as a soil amendment that aids in nutrient management."
"In this seminar, I'll describe the manufacturing of the material, the business plan of the company and the role of agricultural and ecological research in the research and development of this new product."
Of his research, Lewis says on his website: "My research program is wide-ranging in the scope of the questions asked and in the taxa that are studied. There is, however, a common thread to the work that takes place in my laboratory; we seek to understand why and how organisms find, recognize, assess and exploit resources. We ask questions about how insects and nematodes make decisions about resource utilization and what the fitness outcomes of the decisions are. To answer these kinds of questions, we engage in studies of behavior, population ecology, community ecology and evolutionary biology with several groups of insects, nematodes and bacteria. There are also intentional links to more practical pursuits including biological control of crop pests, predicting the impact of crop management on pest and beneficial organisms and restoration ecology. I see no difference between what is traditionally called 'basic' and 'applied' research, thus the links of nearly all of the work in the laboratory to agricultural or environmental concerns is explicit."
Lewis, who joined the UC Davis faculty in 2004, received his doctorate in entomology from Auburn University, Auburn, Ala.; his master's degree in entomology from the University of Missouri, Columbia; and his bachelor's degree in natural resources from Cornell University, Ithaca, NY.

Lewis replaces David Tebeest, University of Arkansas, as editor-in-chief. A member of the editorial board since 2002, Lewis became one of seven editors in 2009. Harry Kaya, emeritus professor of entomology and nematology at UC Davis, is a former editor-in-chief of the journal.
The multidisciplinary journal is described on the web as “an environmentally sound and effective means of reducing or mitigating pests and pest effects through the use of natural enemies. The aim of Biological Control is to promote this science and technology through publication of original research articles and reviews of research and theory. The journal encompasses biological control of viral, microbial, nematode, insect, mite, weed, and vertebrate pests in agriculture, aquatic, forest, natural resource, stored product, and urban environments.”
Topics include:
- Entomology-parasitoids, predators, and pathogens and their use through importation, augmentation, and/or habitat management strategies
- Plant pathology-antagonism, competition, cross-protection, hyperparasitism, hypovirulence, and soil suppressiveness through naturally occurring and introduced agents
- Nematology-predators, parasitoids, and pathogens in biological control through augmentation and/or habitat management strategies and suppressive soils through naturally occurring and introduced agents
- Weed science-vertebrates, invertebrates, and pathogens and their use through classical, augmentative, or bioherbicidal tactics
- Biocontrol of slugs and snails, and others.
“Basically, the journal covers the management of any populations of unwanted organisms through the use of parasites, predators and pathogens,” Lewis said.
