It's the work of museum associate Christine Melvin, who received her bachelor's degree in entomology from UC Davis. It will soon be a beautiful banner that will grace the Bohart.
The Bohart folks ask: "Can you identify all the animals and plants?" The flora and the fauna? Is your favorite insect there? Or maybe your favorite number? 75?
Directed by Lynn Kimsey, UC Davis distinguished professor of entomology, the Bohart Museum houses nearly 8 million insect specimens and is the seventh largest insect museum in North America. It is also home to a live "petting zoo," comprised of Madagascar hissing cockroaches, walking sticks and tarantulas. A gift shop (now online) is stocked with insect-themed t-shirts, hoodies, jewelry, posters, books, candy, collecting equipment, and more.
Meanwhile, the Bohart Museum scientists are seeking donations for their traveling insect specimen displays. They aim to raise $5000 by 11:59 p.m., Oct. 31 for their UC Davis CrowdFund project to purchase traveling display boxes for their specimens, which include bees, butterflies and beetles. These are portable glass-topped display boxes that travel throughout Northern California to school classrooms, youth group meetings, festivals, events, museums, hospitals--and more--to help people learn about the exciting world of insect science.
“When COVID halted our in-person outreach programs, we were still able to safely loan these educational materials to teachers,” said Tabatha Yang, the Bohart Museum's education and outreach coordinator. “Now that UC Davis is open again to students we have all these bright, students on campus with fresh and diverse perspectives. We want to support their talent, so the funds we are raising will go to students for the creation of new traveling displays. This fleet of new educational drawers will expand and update what we can offer. Some of our current displays were created 15 years ago! One can only imagine all the places these drawers have been and all the people who have been inspired."
Like to donate $5? $10? $25? $50? $100? Or more?
You can do so in memory of someone, a place, or your favorite insect! Here's to the bees, the butterflies and the beetles! (And maybe a dragonfly, a syrphid fly or a praying mantis?) Access the donation page and map at https://bit.ly/3v4MoaJ
Gotta love those spiders.
We recently saw an adorable jumping spider (aren't all jumping spiders adorable?) huddled or cuddled (your preference) within a layer of yellow rose petals. It didn't look like a poster child for Halloween. It looked right at home.
It's still there.
In a March 2019 Bug Squad blog, we posted five good reasons to like spiders, compliments of Professor Jason Bond of the UC Davis Department of Entomology and Nematology. He's the Evert and Marion Schlinger Endowed Chair in Insect Systematics in the UC Davis Department of Entomology and Nematology and a newly selected co-editor-in-chief of the journal Insect Systematics and Diversity (ISD), published by the Entomological Society of America (ESA).
“Spiders have been around for 400 million years and are cunning, skillful predators," Professor Bond says. They are "an incredibly diverse group with more than 50,000 species described with probably another 200,000 remaining to yet be discovered."
The five good reasons to like spiders?
- Spiders consume 400-800 million tons of prey, mostly insects, each year. Humans consume somewhere around 400 million tons of meat and fish each year.
- Spider silk is one of the strongest naturally occurring materials. Spider silk is stronger than steel, stronger and more stretchy than Kevlar; a pencil thick strand of spider silk could be used to stop a Boeing 747 in flight.
- Some spiders are incredibly fast – able to run up to 70 body lengths per second (10X faster than Usain Bolt).
- Although nearly all 47,000-plus spider species have venom used to kill their insect prey, very few actually have venom that is harmful to humans.
- Some spiders are really good parents –wolf spider moms carry their young on their backs until they are ready to strike out on their own; female trapdoor spiders keep their broods safe inside their burrows often longer than one year, and some female jumping spiders even nurse their spiderlings with a protein rich substance comparable to milk.
When Professor Bond spoke at the Bohart Museum of Entomology open house, “Eight-Legged Wonders,” on March 9, 2019, showcasing spiders, he drew scores of questions. Following his talk, the visitors participated in interactive activities, including “How to Eat Like a Spider,” “How to Assemble an Arachnid,” "How to Catch a Moth," "Create a Chelicerate" and others. So educational and entertaining and let's hope another one will be on the calendar in the near future! The Bohart Museum, currently closed to the public due to COVID-19 precautions, is located in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus. It is the home of nearly 8 million insect specimens, and also a live "petting zoo" (think Madagascar hissing cockroaches, walking sticks and tarantulas) and an online insect-themed gift shop, stocked with t-shirts, hoodies, jewelry, posters, and collecting equipment.
Meanwhile, Herman or Hermanina, is basking in the sun, getting ready to substantiate Professor Bond's excellent description: "a cunning, skillful predator."
So could research on a fly--a model organism--help us understand and maybe lead to treatment of schizophrenia and other complex disorders?
Postdoctoral fellow Sergio Hidalgo Sotelo of the UC Davis Department will present an in-person seminar on “Using Drosophila melanogaster to Understand Complex Disorders: Insights on the Pathophysiology of Schizophrenia” on Wednesday, Oct. 20 in 122 Briggs Hall, Kleiber Hall Drive.
Sotelo, a researcher in the laboratory of molecular geneticist and physiologist Joanna Chiu, professor and vice chair of the UC Davis Department of Entomology and Nematology, will speak at 4:10 p.m. Plans are to record the seminar for later viewing.
In his abstract, Sotelo relates: “As genome association technologies improve, we have more information regarding the genetic components underlying neurodegenerative and neuropsychiatric disorders such as Alzheimer's, Parkinson's, and schizophrenia. Drosophila melanogaster offers a genetically tractable in vivo system that can be used to perform genetic screens and characterization of genes associated with complex disorders. By combining physiological and behavioral analyses, my work aims to understand the molecular mechanism and neuronal networks involved in some of these conditions.”
Untangling the Mechanisms. “Schizophrenia is a condition that is characterized by its debilitating and poorly understood symptoms," he pointed out. "By studying the genetic component of this disorder, we aim to untangle the mechanisms behind those symptoms. This could potentially help us to develop new and more effective treatments. Using a similar approach would give us insights better understanding of others disorders like Alzheimer's and Parkinson's.”
Said Professor Chiu: “Sergio's exciting thesis research highlights the value of Drosophila as an animal model to study biological processors. To many, it is probably surprising to hear that this tiny insect is constantly used as an animal model to study complex human diseases such as Alzheimer's and Parkinson's. In fact, there are quite a number of similarities between fly and human physiological systems, even in the brain.”
According to Wikipedia: "Starting with Charles W. Woodworth's proposal of the use of this species as a model organism, D. melanogaster continues to be widely used for biological research in genetics, physiology, microbial pathogenesis, and life history evolution. As of 2017, five Nobel Prizes have been awarded to drosophilists for their work using the animal."
Sotelo joined the Chiu lab as a postdoctoral fellow in the summer of 2020. “Despite the difficult situation brought on by COVID, Sergio is making significant progress in his research on biological rhythms," Chiu said. "He has brought his expertise in neurogenetics, infused the lab with creative energy, and contributed to the training and growth of younger investigators in the lab. Recently, he was named a Pew Latin American Fellow in the Biomedical Sciences, a prestigious award for a well-deserved scientist.”
A native of Puente Alto, Santiago, Chile, Sotelo is one of 10 post-docs from across Latin America—including Argentina, Brazil, Chile, Mexico, Peru, and Uruguay—to receive two years of funding to conduct research. The fellows work under the mentorship of prominent biomedical scientists, including alumni of the Pew Scholars Program in the Biomedical Sciences.
The UC Davis Department of Entomology and Nematology seminars are held on Wednesdays at 4:10 p.m. and include both in-person and virtual lectures. All in-person seminars are held in 122 Briggs Hall, while the virtual seminars are broadcast on Zoom. For more information, contact seminar coordinator Shahid Siddique, at email@example.com.
De Lange assembled a project team that wrote a research paper on the agricultural use of drones, published last February in the Journal of Economic Entomology (JEE). It went on to win the JEE 2021 Editors' Choice Award and will be recognized at the Entomological Society of America (ESA) meeting, set Oct. 31-Nov. 3 in Denver. ESA announced the awards online.
The paper, “Drones: Innovative Technology for Use in Precision Pest Management,” is the work of first author Fernando lost Filho, a doctoral student in entomology at the University of São Paulo, Brazil, and a former UC Davis exchange student; remote sensing expert Wieke Heldens of the German Aerospace Center, Wessling, Germany; engineer and drone communication expert Zhaodan Kong, associate professor, UC Davis Department of Mechanical and Aerospace Engineering, and deLange, a former postdoctoral fellow in the Christian Nansen laboratory at the UC Davis Department of Entomology and Nematology and now of The Netherlands.
“Drones can be equipped with a range of attachments, such as sensors, pesticide sprayers, and natural enemyreleasers, and can therefore contribute to more sustainable agriculture in various ways,” said deLange, whose research interests include plant-insect interactions, integrated pest management, chemical ecology and precision agriculture.
Agriculture drones, she said, "are highly versatile and have great commercial potential.”
For the JEE Editors' Choice award, the editors-in-chief nominate papers based on citation, readership and Altmetric scores. The winners are determined by a vote of the JEE subject editors. JEE co-editors-in-chief are Frank Zalom, UC Davis distinguished professor of entomology; Mike Brewer, entomology professor, Texas A&M University; and Nan-Yao Su, distinguished professor of entomology at the University of Florida. JEE is ESA's largest journal by publishing volume and the most-cited journal in entomology. (See ESA website.)
Crop Monitoring Procedures. As agriculturists know, improving crops and crop monitoring procedures are crucial. “Early outbreak detection and treatment application are inherent to effective pest management, allowing management decisions to be implemented before pests are well-established and crop losses accrue,” the authors wrote in their abstract. “Pest monitoring is time-consuming and may be hampered by lack of reliable or cost-effective sampling techniques. Thus, we argue that an important research challenge associated with enhanced sustainability of pest management in modern agriculture is developing and promoting improved crop monitoring procedures.”
Drones can target pest outbreaks or hot spots in field crops and orchards, such as Colorado potato beetle in potato fields or sugarcane aphid in sorghum, the scientists pointed out. “Pests are unpredictable and not uniformly distributed. Precision agricultural technologies, like the use of drones, can offer important opportunities for integrated pest management (IPM).”
But he's an entomologist with an incredible reach that extends in practically all corners of the insect science world. He's like the equivalent of a griffinfly from the extinct genus Meganeuropsis, a huge insect with a wingspan of 27 inches.
Indeed, the reach of UC Davis distinguished Frank Zalom UC Davis distinguished professor, is quite comparable.
Zalom, a noted integrated pest management (IPM) specialist and a past president of the Entomological Society of America (ESA), is a newly elected Honorary Member of the ESA, an honor bestowed for his “long-term dedication and extraordinary contributions” to the 7000-member global organization. Honorary Member is the highest honor that can be afforded an ESA member.
Zalom, praised as “an entomological giant” and “the consummate ambassador to entomology,” joins five other entomologists as Honorary Members. They will be honored at the ESA's annual meeting, Entomology 2021, set Oct. 31-Nov. 3 in Denver.
“Honorary membership acknowledges those who have served ESA for at least 20 years through significant involvement in the affairs of the society that has reached an extraordinary level,” an ESA spokesperson said. “Candidates for this honor are selected by the ESA Governing Board and then voted on by the ESA membership.”
“Dr. Zalom is phenomenal for his sustained service of leadership, research, teaching and mentoring, and in my opinion, he is one of the world's most influential, accomplished and inspirational entomologists,” wrote nominator James R. Carey, a UC Davis distinguished professor of entomology and an ESA Fellow. ESA Honorary Member and ESA Fellow Philip Mulder, emeritus professor and former department chair at Oklahoma State University, noted: “Frank is and was the consummate ambassador to entomology throughout his entire career and around the globe on multiple occasions.”
A 47-year member of ESA, Zalom is an emeritus professor with the UC Davis Department of Entomology and Nematology, and currently a recall professor, continuing his work on IPM of tree, vine and fruiting vegetable crops through several major USDA and CDFA research grants he has received since retiring. Since his retirement, he has brought in more than $1 million in grants. Zalom is also working with Professor Rachael Goodhue, chair of the UC Davis Agricultural and Resource Economics Department on an ongoing pesticide policy research project involving "economic and pest management analyses of potential regulations in strawberry, tomato, and other fruiting crops" in collaboration with CDFA's Office of Pesticide Policy and Analysis.
Zalom directed the UC Statewide Integrated Pest Management Program (UC IPM) for 16 years (1986-2002). “Frank elevated it to 'the gold standard' of the world's IPM programs, emphasizing ecologically based pest management programs for agriculture, urban settings and natural resources,” Carey wrote.
The UC Davis entomologist has authored nearly 400 journal publications or book chapters, and more than 400 other publications. He holds two U.S. patents.
Passionate about moving science policy forward, Zalom served as ESA's Science Policy Committee Chair in 2015. In 2018, he co-organized a two-day summit, Grand Challenges in Entomology in South America, hosted by the Entomological Society of Brazil. The summit focused on invasive species, public health, and sustainable agriculture, and included invited leadership from all entomology societies in Central and South America. Zalom also co-organized the North American and Pacific Rim Invasive Insect and Arthropod Species Challenge Summit, jointly hosted by the entomological societies of America, Canada and British Columbia in Vancouver, BC in 2019.
Highly honored by his peers, Zalom is a Fellow of four scientific organizations: ESA; the American Association for the Advancement of Science, California Academy of Sciences, and Royal Entomological Society. His numerous awards include the BY Morrison Memorial Medal from USDA-ARS and American Society for Horticultural Science (2017), ESA's Recognition Award (2002), Outstanding Achievement Award in Extension Entomology (1992), Excellence in IPM Award (2010), IPM Team Award (2008), and the Pacific Branch Woodworth Award (2011).
Among his UC Davis recognitions are the Consortium for Women in Research Outstanding Mentor Award (2013), James H. Meyer Award (2004), and Academic Senate Distinguished Scholarly Public Service Award (2017).
A native of Chicago, Frank moved to Arizona with his family at age 4. He received his bachelor's degree and master's degrees in zoology and ecology from Arizona State University, 1973 and 1974, respectively, and his doctorate in entomology from UC Davis in 1978. He joined the University of Minnesota faculty as assistant professor before returning to UC Davis in 1980.
“Throughout his career the depth of his knowledge in IPM was matched by the strength of his commitment to teaching students and postdocs, as well as by the power of his dedication to helping growers in all areas of agricultural entomology,” Carey wrote. “A former Fulbright Scholar, Frank is both a visionary and dedicated entomologist who has devoted his life's work to advancing entomology and ESA programs. His expertise is in great demand from colleagues, agriculturists, policy makers, students and more. He is the consummate entomologist, intricately skilled and highly accomplished.”
Zalom is the fifth UC Davis scientist to be selected ESA Honorary Member. W. Harry Lange (1912-2004) received the award in 1990; Donald MacLean (1928-2014), the 1984 ESA president, won the award in 1993; Bruce Eldridge in 1996, and John Edman in 2001.
