The Bohart Museum of Entomology at UC Davis is helping to spread the biodiversity of insects.
Lynn Kimsey, director of the Bohart Museum and a distinguished professor of entomology, UC Davis Department of Entomology and Nematology, recently received a request for duplicate specimens of beetles, moths and butterflies for a Biodiversity Science Museum and Research Center to be headquartered at the research institution, Atatürk University, in Erzurum, Turkey.
“We're gifting them 350 large-bodied beetles, moths and butterflies for their display,” she said. “The specimens are all duplicates of material we collected in Papua New Guinea about a decade ago.”
Levent Gültekin, a professor at Atatürk University, emailed Kimsey that he and his colleagues are working on “creating a Biodiversity Science Museum and Research Center belonging to Atatürk University. Our concept will be actually a natural history museum. This is rather new topic here, and it will be the first museum in Eastern Turkey if we can succeed. As a first step, we are working on a permanent exhibition in four settings: Arthropoda (majority insect) diversity, Plant diversity, Vertebrate and Paleodiversity.”
“For insect (and other arthropods), we are planning to hang 100 exhibition boxes (30x40 cm in size) to show great diversity for this group,” Gültekin related, adding that “Our insect collection almost 100 percent comes from Turkey; but we would like to allocate one fourth of boxes for other zoogeographical realms except for Palearctic.”
The Bohart Museum is glad to oblige, Kimsey said.
Atatürk University is a land-grant university established in 1957 inErzurum in the Eastern Anatolia Region. The university consists of 23 faculties, 18 colleges, 8 institutes and 30 research centers. “Since its establishment in 1957, it has served as a hub of educational and cultural excellence for the eastern region,” according toWikipedia. The Eastern Anatolia Region is home to some 6 million people.
The Bohart Museum, now celebrating the 75th anniversary of its founding by the late Richard M. Bohart, UC Davis professor of entomology, is home to some 8 million insect specimens, collected from around the world. It also houses an insect-themed gift shop, now online; and a live “petting zoo,” comprised of Madagascar hissing cockroaches, stick insects and tarantulas.
The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane, is currently closed to the public due to COVID-19 pandemic precautions.

She will deliver her in-person seminar at 4:10 p.m. in Room 122 of Briggs Hall.
“Growers and pest control advisors in California suspect that European earwigs (Forficula auricularia) damage young citrus fruit,” she writes in her abstract. “However, very little is known about herbivory by earwigs on citrus fruit. Our work details characteristics of herbivory by earwigs on citrus fruit and the use of sticky and pesticide barriers to manage earwigs and other citrus pests.”
Kahl, awarded her doctorate in August, focused her research on understanding the role of European earwigs in California citrus; developing a whole systems approach to manage earwigs and other citrus pests; and feeding preferences of fort-tailed bush katydids and citrus thrips on California citrus.
Kahl is now an ecological pest management specialist at Community Alliance with Family Farmers, Davis. She leads projects and extension efforts on sustainable pest management tactics.
She received an ongoing grant in 2019 from the Citrus Research Board on “Characterizing Earwig Damage to Citrus Fruits, and Damage Prevention using Trunk Barrier Treatment.” She also received a National Science Foundation Graduate Research Fellowship, awarded in 2017, and a 2018-19 Keller Pathways Fellowship (for entrepreneurship) from the University of California.
Kahl holds a bachelor's degree in biology from Whitman College, Walla Walla, and a master's degree in entomology from the University of Maryland, College Park. She studied abroad in a six-month School for International Training program in Jaipur, Rajasthan, India in 2010. Her research topic: Village dairy production in Haryana and Orissa.
This is the department's first seminar of the fall series. Many of the seminars will be virtual, said nematologist Shahid Siddique, who is coordinating the seminars. For more information,contact him at ssiddique@ucdavis.edu

UC Davis Distinguished Professor James R. Carey will pay selected students $1000 each to write a paper dealing with human hibernation and longevity--a two-fold project aimed at assisting him with his research and helping students learn how to research, write, illustrate, finalize and deliver the equivalent of a quality term paper.
"With a heavy fall quarter teaching load and other demands during this academic year, I am in need of help in researching the literature on the biology of hibernation and concepts associated with its integration into the human life course," Carey announced, adding that he is "in the early stages of writing a theoretical paper tentatively titled “Human Hibernation as a Future Life Course Option."
The deadline to apply is 5 p.m., Friday, Oct. 1. UC Davis students at all levels and all majors may apply. "It's a report equivalent to the quality term paper I expect in my class that would receive an A or an A+," Carey said.
Carey said he hopes to assemble an interdisciplinary team of 10 to 12 students able and willing to invest the time (60-70 hours) to write the equivalent of a 2,500-word term paper on one of 10--or possibly more--topics. Research and writing efforts will be spread over the 2021-22 academic year. He will compile and format their papers in “proceedings” and publish as both a print and digital book, using the Barnes and Noble Press self-publishing website. The students are also free to re-purpose their papers.
Carey is seeking papers similar to the quality of the three award-winning term papers that his Longevity and Human Development students submitted in the UC Davis Lang Writing Prize Competition. Two students won the top prize in their categories in both 2020 and 2021, and another scored third place in 2021.
Paper Topics (Tentative)
1. Ecology and population biology of dormancy
2. Physiology and ecology of mammalian hibernation
3. Human torpor: Historical, accidental and medical
4. Prospective role of human hibernation in deep space exploration
5. Historical rates of biomedical progress in disease mitigation and cures
6. Reconfiguring the human life course
7. The biology, psychology and behavior of long-term isolation and separation
8. Personal, family and societal consequences of “dropping out”
9. The biology, behavior and psychology of individuals re-entering society
10. The future of human longevity: Emerging concepts
Students interested in participating in the project can email Carey at jrcarey@ucdavis.edu with the subject line “Human Hibernation Project" and include in the body:
- your UC Davis major and year
- your first and second choices of paper topic by number or topic (e.g., dormancy; life course; etc);
- whether you would be interested in participating if another student was assigned your topic(s) of greatest interest (yes/no)
- a 100 to 150-word statement on why you are interested and would be a good choice to join the team; and
- a 1-page (only) CV. Writing experiences and skills are a plus, he said, but "I am mostly interested in highly motivated and self-directed students who are willing to dive deeply into the literature related to my broad topic and to synthesize the results. I will teach you how to write your paper competently and professionally."
Carey will interview the top candidates via Zoom and make final selections within a week. If selected, they will have
"plenty of time" to enroll in his one-credit ENT 99 or 199, he said.
Timetable
Fall Quarter (2021): Frame, research and finish a preliminary working draft including at least rough figures and tables and references (using Endnotes bibliographic software).
Winter Quarter (2022): Complete research, finalize structure and submit near-final draft, all figures, tables and references cited finished
Spring Quarter (2022): Finalize narrative, figures, tables and references. Submit final version.
Carey, a senior scholar at the Center for the Economics and Demography of Aging at UC Berkeley, focuses his research on the biology and demography of aging and lifespan, particularly the use of insect models. A national-award winning teacher, he offers worldwide workshops on best practices in information design and presentation strategies. His most recent book is Biodemography: An Introduction to Concepts and Methods (2020, Princeton University Press), co-authored by Deborah A. Roach, professor and chair of the Department of Biology, University of Virginia.

Dr. Summers, a member of the UC Davis Department of Entomology and Nematology faculty since 1992, served 42 years as a research entomologist at the Kearney Agricultural Research and Extension Center (KARE), Parlier, Fresno County, part of the UC Division of Agriculture and Natural Resources (UC ANR). He joined the world-class research facility in 1970, the year he received his doctorate in entomology from Cornell University. He was stationed at KARE throughout his career, and served for a time as its director.
Dr. Summers was affiliated with the UC Berkeley faculty from 1970 to 1992, before joining the UC Davis faculty. Specializing in pest problems of field and vegetable crops, he developed economic thresholds and management strategies for more than a dozen pests, including the silverleaf whitefly. During his career, he authored more than 200 publications, including articles, book chapters and research papers, and delivered more than 800 presentations.
“Charlie was a true IPM entomologist and was one of the group of young faculty who contributed mightily to the UC Statewide Integrated Pest Management Program (UC IPM) when it was first getting off the ground and at its most vulnerable stage,” said Frank Zalom, UC Davis distinguished professor of entomology who directed UC IPM for 16 years.
Developed Economic Thresholds for Important Pests
“He was quiet but contributed greatly in many ways,” Zalom said. “Charlie did indeed develop economic thresholds for several important pests. Economic thresholds are recognized as one of the foundations for IPM decision-making, but doing the field work to develop research-based thresholds is incredibly difficult and few researchers actually do this type of research anymore. It has become a lost art and, unfortunately, this type of work has also become under-appreciated except by IPM practitioners who are truly trying to reduce input costs for pest control.”
A Passion for IPM
“I remember first meeting Charlie Summers in Robert van den Bosch's lab when I was a graduate student,” recalled Mary Lou Flint, Extension entomologist emerita, Department of Entomology and Nematology and formerly UC IPM's associate director for urban and community IPM.
“He was already at Kearney, but I was working on a parasitoid of the spotted alfalfa aphid, so we had alfalfa aphids and parasites in common. And a passion for IPM. Charlie was really one of the original unsung promoters of IPM in California.”
“Charlie was a true dirt-kicking field entomologist of a stripe all too uncommon today,” said Flint who retired in 2014. “He was passionate about ecology-based integrated pest management and dedicated his career to forwarding the science of IPM.
“Charlie's research spanned many field and vegetable crops and he could always be called on to provide expertise about pest or beneficial arthropods on any of these crops, but I worked most closely with him on alfalfa,” she said.
“In the 1980s, in the early days of the UC Statewide Integrated Pest Management program, Charlie was a leader in developing, researching and promoting IPM programs for alfalfa," Flint related. "He played a critical role in coordinating and carrying out interdisciplinary research, training farm advisers, and promoting IPM programs to PCAs (pest control advisors) and farmers. He was one of the key players in the development of Integrated Pest Management for Alfalfa Hay released in 1982, which was the first of the UC Statewide IPM Program's IPM manual series of books that eventually covered 16 California crops. He was a fountain of information, and the book could not have been written without him."
Walter Bentley, now IPM entomologist emeritus, remembers meeting him at his job interview “at the old office on M street in Bakersfield on August 16, 1977. Like Pete Goodell, we ended up working together at Kearney. I would never have guessed that. Little did I know how he liked to play jokes." He remembers when Summers hung up a Big Mouth Billy Bass Singing Sensation plaque at Bentley's office entrance. "I will have to go out and play the tune, Take Me to the River, Drop Me in the Water."
“He helped me a lot and I am thankful for that,” said Bentley, who retired in 2012. Goodell retired in 2017.
Recipient of Charles W. Woodworth Award
In 2009, Summers received the prestigious Charles W. Woodworth Award from the Pacific Branch of the Entomological Society of America (PBESA), the highest honor awarded by the branch, which encompasses 11 U.S. states (Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, Oregon, Utah, Washington and Wyoming); several U.S. territories, and parts of Canada and Mexico.
At the awards ceremony, Summers drew praise for developing economic thresholds, determining at what point the cost of pest damage exceeds the cost of pest control. He "pioneered economic thresholds for seven pests in four crops, and developed management strategies for a combination of 28 crops, insect and disease pests," his nominators wrote. He also was praised for his research on the interactions among insects, diseases and weeds on alfalfa hay and how they individually and as a whole, influence yield and quality. His work led to improved best management decisions and decreased pesticide use.
In addition, Summers drew praise for his research on reflective mulches, used to delay and reduce aphid and whitefly infestations on squash, pumpkins, cucumbers and tomatoes and other crops. He teamed with plant pathologist Jim Stapleton and vegetable crop specialist Jeff Mitchell, both based at Kearney.
In a UC Davis news story published March 25, 2009, Summers recalled: “In the mid-1990s, Dr. Stapleton and I embarked on a series of studies to determine if aphids, aphid-transmitted viruses, and silverleaf whitefly could be managed using plastic reflective mulches. Dr. Jeff Mitchell later joined our team. We evaluated a wide variety of crops as well as different types of mulches. We were able to manage all three of these pests without the need to rely on the use of insecticides.”
“Our studies have clearly demonstrated that the use of these mulches are effective in delaying the onset of silverleaf whitefly colonization and the incidence of aphid-borne virus diseases,” Summers said. “The data shows that marketable yields with summer squash, cucumber, and pumpkins grown over reflective mulch are higher than those in plants grown over bare soil, both with and without insecticide. We also determined that the use of reflective mulch, without insecticides, leads to significantly increased yields of fall planted cantaloupes.”
Another highlight of his career: his work on the biology of corn leafhopper and corn stunt spiroplasma. He proved that the corn leafhopper can overwinter in the San Joaquin Valley and that the pathogen, Spiroplasma kunkelii overwinters in it. “Before this research, it was assumed that tropical insects such as corn leafhopper could not overwinter in our temperate climate, but were reintroduced each year from Mexico,” Summers noted. "The findings led to better strategies for managing the pest and the pathogen."
Born Dec. 24, 1941 in Ogden, Utah, and a graduate of Davis High School, Kaysville, Utah, Charlie grew up on the family farm and “always knew” he wanted an agricultural career. At age 12, he decided to go to college “when I was at the wrong end of a short-handled hoe,” he told communications specialist Jeannette Warnert in a June 12, 2012 news story announcing his retirement.
He continually described his work at Kearney as his “dream job.”
“The job at Kearney was an absolutely perfect fit for me,” Summers told Warnert. “It was a dream job. I look forward to coming to work every morning and would sometimes shake my fist at the sun going down at night. I've loved every minute I've been here.”
Summers said that the objective of his job--to help farmers develop successful pest management strategies --stayed the same, but technological advances dramatically changed the way he did his work.
“We've had the advent of computer technology, the use of mathematical models, work that can now be done at the DNA level,” he said. “It's put a whole new face on our ability to do research.”
Following his retirement and the death of his wife, Beverly, Summers moved back to Utah to be with family and to pursue his favorite pastime, fly fishing.
“I'll be living 15 minutes from the Wasatch Mountains,” he told Warnert. “There's a lot of good fishing there.”
Summers was an Eagle Boy Scout, a pilot, an avid fly fisherman and hunter, and a member of the Church of Jesus Christ of Latter-day Saints. A graveside service took place Aug. 21 in the Plain City Cemetery, Plain City, Utah.
Survivors include his sister, Marilyn (John) Diamond and three nephews, four great-nieces and five great-nephews.

The fall quarter seminars begin Sept. 29 and conclude Dec. 1.
"The fall quarter series will be a mixture of in-person and virtual seminars and we have an exciting list of seminars that includes both national and international speakers," Siddique said. "Both in-person and virtual seminars will be held on Wednesdays at 4 p.m. (Pacific Time)."
The in-person seminars will take place in Room 122 of Briggs Hall. "We have already lined up seven speakers who will be giving in-person seminars," he said. Those will be recorded for later viewing.
Three of the seminars will be virtual. "Virtual seminars will be accomplished using the Zoom meeting software package," Siddique related. A Zoom link will be provided a week before the seminar.
First on tap will be the exit seminar of doctoral candidate Hanna Kahl of the lab of UC Davis distinguished professor Jay Rosenheim. She will speak on "Herbivory of Citrus Fruit by European Earwigs in California" at 4 p.m., Wednesday, Sept. 29. This will be an in-person seminar.
No seminar will be held Nov. 3, which conflicts with the annual meeting of the Entomological Society of America (ESA), set Oct. 31-Nov. 3 in Denver, Colo. Many faculty attend the annual meeting.
Siddique joined the UC Davis Department of Entomology and Nematology in July 2019 after serving as a research group leader for several years at the University of Bonn, Germany. Research in the Siddique lab focuses on basic as well as applied aspects of interaction between parasitic nematodes and their host plants. "The long-term object of our research is not only to enhance our understanding of molecular aspects of plant–nematode interaction but also to use this knowledge to provide new resources for reducing the impact of nematodes on crop plants in California."
For further information on the seminars, contact Siddique at ssiddique@ucdavis.edu.
