Lynn Kimsey, director of the Bohart Museum of Entomology and UC Davis professor of entomology, will answer questions from 11 a.m. to 11:45 a.m., on Friday, May 22 at the Bohart's first-ever virtual open house on FacebookLive. To watch or participate, access the Bohart Museum Facebook site. It will be recorded for those unable to watch it at that time.
Kimsey, an authority on wasps and bees, is a two-time past president of the International Society of Hymenopterists. The director of the Bohart Museum and executive director of the Bohart Museum Society since 1990, she has also served as interim chair and vice chair of the UC Davis Department of Entomology, now the UC Davis Department of Entomology and Nematology.
She recently won the C. W. Woodworth Award, the highest honor given by the Pacific Branch, Entomological Society of America. (See news story.)
“We thought people would be interested in talking to a wasp/bee expert given all the news about wasps and with spring coming and more people tuning into nature and their back yards due to sheltering in place,” said Tabatha Yang, education and outreach coordinator. “We anticipate ‘murder hornet' questions.
“We host open houses to connect people directly to scientists,” Yang said. “Since the museum is closed at this time and social distancing is required, we are setting this up so people can connect with Lynn. We hope to do this regularly with other scientists, but this will be our first.”
North America's first known colony of the Asian giant hornet, Vespa mandarinia, was detected (and destroyed) in September 2019 on Vancouver Island, British Columbia. A single V. mandarinia was found dead in Blaine, Wash., in December 2019.
Three entomologists, including Kimsey just published research on this and the 21 other known species of hornets in the genus Vespa, in the journal Insect Systematics and Diversity.
The article, “The Diversity of Hornets in the Genus Vespa (Hymenoptera: Vespidae; Vespinae); Their Importance and Interceptions in the United States,” is the work of lead author Allan Smith-Pardo, U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS); and co-authors James Carpenter of the American Museum of Natural History's Division of Invertebrate Zoology, and Lynn Kimsey.
The Bohart Museum is also celebrating the birthday anniversary (May 23) of Carl Linnaeus, the father of taxonomy. Linnaeus (1707-1778), was a Swedish botanist zoologist and physician who formalized the modern system of naming organisms. “It's a good time to celebrate biodiversity, scientific discovery, and museum collections,” Yang said.
In addition, talented Bohart student associates have crafted downloadable coloring pages for the family craft activity.
The Bohart also has pre-recorded tours linked to its website http://bohart.ucdavis.edu/
And timely, too!
While many folks are panicking about the first detected (and destroyed) colony of Asian giant hornets, aka “murder hornets,” in North America, three entomologists have just published research on this and the 21 other known species of hornets in the genus Vespa, in the journal Insect Systematics and Diversity.
The article, “The Diversity of Hornets in the Genus Vespa (Hymenoptera: Vespidae; Vespinae); Their Importance and Interceptions in the United States,” is the work of three entomologists: lead author Allan Smith-Pardo, U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS); and co-authors James Carpenter of the American Museum of Natural History's Division of Invertebrate Zoology, and Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis.
North America's first known colony of the Asian giant hornet, Vespa mandarinia, was detected (and, yes, destroyed) in September 2019 on Vancouver Island, British Columbia. A single V. mandarinia was found dead in Blaine, Wash., in December 2019.
“Hornet species identification can be sometimes difficult because of the amount of intraspecific color and size variation,” the authors wrote in their abstract. “This has resulted in many species-level synonyms, scattered literature, and taxonomic keys only useful for local populations. We present a key to the world species, information on each species, as well as those intercepted at United States ports of entry during the last decade.”
Vespa species are “primarily predators of other insects, and some species are known to attack and feed on honey bees (Apis mellifera), which makes them a serious threat to apiculture,” the authors wrote in their abstract.
In the USDA-funded research, the trio combed through scientific literature and museum collections to separate the species. They list their sources and offer insights on the distribution of each hornet, and a discussion.
The Asian giant hornet's distribution is India, Sri Lanka, Bhutan, Nepal, Myanmar, Thailand, Laos, Vietnam, Malaysia, Malaya, China, Hong Kong, Taiwan, eastern Russia, Korea, Japan (including Ryukyus), the authors wrote.
The Bohart Museum of Entomology, home of a global collection of nearly eight million insect specimens, houses 20 specimens of V. mandarinia. The largest one, a queen, measures about an inch and a half long, Kimsey said.
“Insects introduced in the United States often come in cargo boxes from Asia to U.S. ports, establish colonies, and expand their range,” she said.
The only known European hornet to colonize the United States is Vespa crabro, introduced on the East Coast in the 1800s. “It is now fully established in the southeastern U.S,” Kimsey said. “A decade or more ago, there was a colony of another species, Vespa asiatica, reported near the Port of Long Beach but nothing ever came of that.”
What's next for the research team? "We will be continuing to create online identification tools and a detailed website," Kimsey said.
"From 2010 to 2018, there have been close to 50 interceptions of Vespa (hornets) and Vespula (yellow jackets (Vespula) at U.S. ports of entry. Little less than half of those interceptions were hornets. The Vespa species intercepted include V. bellicosa, V. crabro, V. orientalis, V. mandarinia, and V. tropica. One of the interceptions of significance was an entire nest of V. mandarinia containing live brood and pupae that was sent via express courier from Asia. All species of Vespa, except V. crabro, which is already introduced into the eastern United States, are considered of quarantine importance by the USDA-APHIS."
A website, Invasive Hornets, part of a cooperation between the USDA, Animal Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ) and the University of Georgia, is taking shape. According to the journal article: "This website contains more than 1,000 stacked, high-quality images of all the species and most of the races of the genus Vespa. It is important to have the resources for the identification and prevention of introduction of non-native species and to understand the potential effects of invasive hornets in our ecosystems. Hornets are dangerous for the beekeeping industry because they can alter pollination in agriculture and disrupt the beekeeping industry, as well as create public health and safety problem."
The authors credited senior museum scientists Christine Lebeau of the American Museum of Natural History and Steve Heydon of the Bohart Museum of Entomology “for helping to process the loan of Vespa material.” Mary Burns of the National Identification Services (NIS) of the USDA-APHIS- Plant Protection and Quarantine (PPQ) provided information about the number of interceptions of Vespa at U.S. ports of entry.
In an article posted in Entomology Today, science writer-educator Leslie Mertz wrote that the team is "building a publicly available, online adjunct to the newly published key that uses menus of distinguishing characteristics, as well as illustrations and photographs. They hope to have the online key up and running in 2021.”
Agricultural entomologist Emily Bick is targeting you.
Lygus hesperus, a serious pest of strawberries--as well as cotton, and seed crops such as alfalfa--causes an estimated $40 million in annual losses to California's strawberry industry.
Bick, who received her doctorate in entomology last year from UC Davis and is now a postdoctoral fellow at the University of Copenhagen, is a newly selected recipient of an American Association of University Women (AAUW) American Publishing Grant and her subject is the lygus bug immigration and aggregation in California strawberries.
The $6000 grant is designed to support women over a two-month period in the summer as they prepare a solo-authored manuscript.
Bick's application focused on her scientific modeling work that originated from her Ph.D. program. Her application detailed the academic women who supported her career, including one of her mentors, Cornell University entomology professor Laura Harrington. Additionally, women students she mentored while at UC Davis provided letters of support.
“Prior to receiving this good news, my fiancé, Nora Forbes, and I decided to get married in the historic home of the AAUW in St. Paul, Minn.,” Bick said. “We are both aware of AAUW's legacy of supporting women in their academic pursuits since 1881 and wanted to celebrate in a location in line with their pioneering vision.” Forbes is a statistician at the Danish Medtronic office.
Earlier this year, Bick received a $23,000 fellowship from the American Scandinavian Foundation for her proposal, "Designing Pest-Resilient Apple Orchards Using Bespoke Models." The project will start immediately following the AAUW grant.
As a postdoctoral fellow at the University of Copenhagen, the UC Davis alumnus is a member of Professor Lene Sigsgaard's research team. She received a $244,000 postdoctoral grant from the Danish Innovations Fund to estimate insect population dynamics in relation to FaunaPhotonics's LIDAR insect sensor. LIDAR stands for light detection and ranging.
Emily's entomological journey began at Cornell University, where she received her bachelor's degree in entomology in 2013. She then received two degrees in entomology from UC Davis: her master's degree in 2017 and her doctorate in 2019.
Bick, who specializes in integrated pest management, helped anchor the UC Davis Department of Entomology and Nematology's Linnaean Games Team that won the national championship at the Entomological Society of America (ESA) meeting in 2016, and the University of California (UC Davis and UC Berkeley) Linnaean Games Team that won the national championship in 2018. The Linnaean Games, launched in 1983, are lively question-and-answer, college bowl-style competitions on entomological facts and played by winners of the ESA branch competitions. The teams score points by correctly answering random questions. (Watch the championship game on YouTube).
While at UC Davis, Bick served as vice president of the UC Davis Entomology Graduate Student Association (EGSA). ESA honored her as a Board-Certified Entomologist in 2014, and the Student Certification Award in 2018. She served as an emergency medical technician from 2008 to 2017.
We missed it, too. So did the ants and other insects.
The Department of Entomology and Nematology annually hosts dozens of popular Picnic Day events at Briggs Hall and at the Bohart Museum of Entomology. But this year, due to the coronavirus pandemic, “closed” was the word of the day.
"Closed." It's not a popular word when you're craving to show your audience the wonderful world of insects.
However, this year the campuswide Picnic Day Committee hosted a virtual tour of some of the planned events, and posted this link: https://picnicday.ucdavis.edu/virtual/
The spotlight paused on the Bohart Museum, which houses nearly eight million insect specimens; the seventh largest insect collection in North America; the California Insect Survey, a storehouse of the insect biodiversity; and a live “petting zoo” comprised of Madagascar hissing cockroaches, walking sticks, tarantulas and the like. It also is the home of a gift shop, stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
Directed by UC Davis entomology professor Lynn Kimsey for 30 years, the museum is named for noted entomologist Richard Bohart (1913-2007). The Bohart team includes senior museum scientist Steve Heydon; Tabatha Yang, education and outreach coordinator; and entomologist Jeff Smith, who curates the Lepidoptera (butterflies and moths section).
If you browse the Bohart Museum site, you'll find fact sheets about insects, written by Professor Kimsey.
But if you want to see the Bohart Museum's virtual tours, be sure to watch these videos:
- Director Lynn Kimsey giving a Bohart Museum introduction
- Tabatha Yang, education and outreach coordinator, presenting an arthropod virtual tour
- Diane Ullman, professor of entomology and former chair of the department, presenting a view of the Lepidodpera section.
Also on the UC Davis Virtual Picnic Day site, you'll learn “How to Make an Insect Collection," thanks to project coordinator James R. Carey, distinguished professor, UC Davis Department of Entomology and Nematology; and "Can Plants Talk to Each Other?" a TED-Ed Talk featuring the work of ecologist Rick Karban, professor, UC Davis Department of Entomology and Nematology.
Other research work that draws widespread attention at the annual UC Davis Picnic Day is the work of UC Davis medical entomologist-geneticist Geoffrey Attardo, assistant professor of entomology. A global authority on tsetse flies, he specializes in reproductive physiology and molecular biology, in addition to medical entomology and genetics.
"Female tsetse flies carry their young in an adapted uterus for the entirety of their immature development and provide their complete nutritional requirements via the synthesis and secretion of a milk like substance," he says. PBS featured his work in its Deep Look video, “A Tsetse Fly Births One Enormous Milk-Fed Baby,” released Jan. 28, 2020. (See its accompanying news story.)
PBS also collaborated with the Attardo lab and the Chris Barker lab, UC Davis School of Veterinary Medicine, for a PBS Deep Look video on Aedes aegypti, the mosquito that transmits dengue fever and Zika. The eggs are hardy; "they can dry out, but remain alive for months, waiting for a little water so they can hatch into squiggly larvae," according to the introduction. Watch the video, "This Dangerous Mosquito Lays Her Armored Eggs--in Your House."
In the meantime, the UC Davis Picnic Day leaders are gearing up for the 106th annual, set for April 17, 2021. What's a picnic without insects?
She's been making her mark in all three since enrolling in 2016 in the UC Davis Department of Entomology and Nematology's Ph.D. program, with a designated emphasis in the biology of vector-borne diseases.
Winokur, who studies with major advisor Christopher Barker, associate professor, Department of Pathology, Microbiology and Immunology, School of Veterinary Medicine, is a newly selected fellow of Professors for the Future (PFTF).
This is a program sponsored by UC Davis Graduate Studies “to recognize and develop the leadership skills of outstanding graduate students and postdoctoral scholars who have demonstrated their commitment to professionalism, integrity, and academic service.”
As a fellow, she will receive a stipend of $3000. Traditionally, approximately 12 fellows annually are selected to participate in the yearlong program, launched in 1992.
The PFTF program is designed to prepare UC Davis doctoral students and postdoctoral scholars “for an increasingly competitive marketplace and a rapidly changing university environment,” according to PFTF co-directors Ellen Hartigan-O'Connor, acting associate dean of UC Davis Graduate Studies, and Teresa Dillinger, academic administrator.
During the year, the fellows will receive formal training-in-teaching methods and course design; participate in a seminar course on ethics and professionalism, and meet regularly for roundtable panel discussions to promote their professional development, intellectual growth and leadership skills, the directors said.
The fellows will work on projects of their own design to enhance their graduate or postdoctoral experience and professional development of their colleagues. They summarize their projects in end-of-the-year reports. (See 2019-2020 fellows.)
Winokur titled her successful proposal, “Addressing Financial Barriers to Participation in STEM (Science, Technology, Engineering and Mathematics).”
“Graduate students perform many roles as researchers, mentors, educators, communicators, service leaders, and humans,” wrote Winokur, who is president of the UC Davis Entomology Graduate Student Association. “Financial insecurity affects students' abilities to perform these roles well, and provides a leg up to students with financial support beyond a graduate student stipend. We know that diversity is important in academia; cultivating talent from folks across the social spectrum leads to innovative and appropriate solutions.”
“Addressing financial barriers to participation in STEM graduate programs will lead to more diverse and inclusive programs,” she wrote. “Further, financial insecurity affects those who enters graduate school in the first place; research experience is often required to be considered for acceptance into graduate school, which unfortunately is often offered in the form of unpaid research internships. This can filter out low-income students early, making academia even more elite than it already is.”
Winokur will collaborate with existing resources on campus to set up a series of workshops to address the issues, focusing on three points: (1) creative ways to fund your research (2) how to support your research mentees—why unpaid labor filters low income and other disadvantaged students, and (3) making your teaching cheaper—how to make education more accessible for low-income and other disadvantaged students.
“I've been interested in applying to the Professors for the Future program for a couple years,” she said. “This year, I feel that I am at a good point in my graduate career to develop my skills through the PFTF coursework and to contribute to the graduate student community through a PFTF project.”
Since 2016, the UC Davis doctoral student has developed her teaching, mentoring, course development, and leadership skills through various courses and programs, “which has led to a basic understanding of my teaching philosophy and pedagogy.” She aims to develop her skills to “further align with my core values of diversity, equity, and inclusion in the classroom and laboratory.”
Olivia grew up in Laguna Niguel, Calif. where she focused on science at the Dana Hills High School Health and Medical Occupations Academy. She holds a bachelor's degree, 2015, from Cornell University, where she majored in interdisciplinary studies, focusing on the environmental effects on human health. While at Cornell, she worked as an intern for the National Institutes of Health, working on climate change initiatives for the National Institute of Environmental Health Sciences and the Fogarty International Center.
Winokur is a National Science Foundation Graduate Research Fellowship. She is a two-time recipient of the Bill Hazeltine Memorial Research Award, given annually to an outstanding UC Davis graduate student studying vector-borne diseases.
Winokur, who researches Aedes aegypti mosquitoes, is the co-author of research published in several journals, including PLOS Neglected Tropical Diseases. Her first first-author paper, “Impact of Temperature on the Extrinsic Incubation Period of Zika Virus in Aedes aegypti” was just published in March.
Since 2017, she has served as a volunteer with the California Department of Public Health's Vector-Borne Disease Section, assisting with hantavirus and plague surveillance by rodent trapping and testing.
Winokur mentors undergraduate students in the UC Davis Research Scholars Program in Insect Biology (RSPIB), founded and directed by faculty members Jay Rosenheim, Joanna Chiu and Louie Yang, UC Davis Department of Entomology and Nematology.
Active in STEM projects, Winokur co-founded GOALS (Girls' Outdoor Adventure in Leadership and Science) in 2017, a program that develops and runs free two-week summer science programs for high school girls and gender expansive youth from backgrounds underrepresented in STEM fields. The girls learn science, outdoor skills and leadership hands-on while backpacking in Sequoia National Park./span>
