Entomology Digest – Spring 2024
Letter from the Chair
Entomology Community and Friends of the Department,
Swarm to Table, Version 4. On Saturday, April 13 our Undergraduate Entomology Society (UES) together with support from Slow Food UW, and MIGHTi hosted the 2024 Swarm To Table (S2T) event, from 2:00-5:00 pm, at The Crossing Event Center. This event represented the fourth annual Swarm to Table event and the group was again able to sell out 300 tickets for the third year in a row. The S2T event celebrates insects in food, art and human culture. Highlights of this year’s event include an insect food-tasting menu, an art gallery showcase including art from UW students and local community members, and an information expo with people from across the Midwest involved in entomophagy and agriculture. Entomophagy is the practice of humans consuming insects as food, and this encompasses a wide range of culinary traditions and is gaining recognition for its nutritional and environmental benefits. We learn and appreciate that worldwide, thousands of species of insects contribute to human diets, and many are prized as delicacies. For creative cooks, the vast biodiversity of insects offers a palette of unique flavors, unmatched in breadth throughout the animal kingdom.
UES’s continual goal is to break the stigma around insects as a food source through exposure in a way that is fun, hands-on and attractive to both insect lovers and those who may not know much about insects. UES President Ava Schassler sees the event as the perfect opportunity to do that. “We want people to come and see the atmosphere and be like, oh, this is actually pretty cool. If they can leave not feeling scared of insects or have the stigma around the idea, I think we did our job,” Schassler said. Addressing stigma about insect eating was one of the major reasons S2T started in 2019. Co-founder and current partner of the event, Dr. Valerie Stull, aimed to highlight positive aspects of insects through art and comradery. Dr. Stull currently helps with two major research projects at UW involving entomophagy. The first is creating a black soldier fly colony on campus — a species increasingly used in agricultural practices by taking food waste or livestock manure and turning it into protein. They hope the colony can help manage on-campus food waste and produce protein for poultry feed. “Since our initial event in 2019, S2T invites the curious public to explore insect agriculture and cuisine, where we celebrate the role of insects in human health, sustainable agriculture, and existing food and artistic culture.”, remarks Dr. Stull.
Global Health Program (major and certificate). Global health is about improving health for everyone, while considering the connections among people, animals, plants, and the planet. Students explore how human health intersects with economic development, healthcare access, food systems, environmental health, and climate change in order to address the root causes of disease around the world. The program helps students develop a broad, planetary-scale perspective that can be applied to community, state, national, and international health challenges. The program was launched in 2020, and has grown steadily under the direction of Dr. Susan Paskewitz, Faculty Director of the Global Health Program. Over the past three years, the Program has increased enrollments in both the major and the certificate and has become the second largest undergraduate major in all of the College of Agriculture and Life Sciences.
Students in the global health major study human health and well-being with an emphasis on empathy, cultural awareness, and collaborative approaches. The major, which covers bioscience and public health, provides students with foundational knowledge in disease and epidemiology, food systems, environmental health, and public health and policy. Majors are encouraged to pursue their own areas of interest through coursework and by participating in field experiences, laboratory research, internships, and volunteer work.
Global health students learn to take a broad, planetary-scale perspective, and apply it to challenges at community, state, national, and international levels. This big-picture perspective is interwoven through nearly all aspects of the global health major, including classes, capstone experiences, lab opportunities, and internships. Global health field experiences, which range from one week to a full semester, expose students first-hand to complex global health challenges in diverse settings, and give them the opportunity to learn from community members and practitioners who are working to address these issues.

Zackary Sieb and Victoria Salerno were among 11 finalists in the Three-Minute Thesis (3MT) international research communication competition, held on Feb 16, in which graduate students explain their research to a general audience. Students in research-based master’s and PhD programs from all disciplines are eligible to compete, and prizes were awarded to the winners. The Department of Entomology was fortunate to have 2 finalists among the 11 selected for the campus competition.
Dan Young will receive the 2024 Michigan State University Distinguished Alumnus Award from his beloved alma mater:
The MSU Department of Entomology is proud to announce the 2024 Distinguished Alumnus Award will go to Daniel K. Young, Ph.D., University of Wisconsin-Madison. Young received his bachelor, master’s, and Ph.D. in Entomology from MSU. He has been on the faculty at the University of Wisconsin since 1982. Over the course of his 41-year career, Young has advanced the study of beetle biodiversity; directed the University of Wisconsin Insect Collection; led national and international scholarly societies; and perhaps most significantly taught foundational entomology courses to countless college students.
Young is an internationally recognized expert in beetle taxonomy and systematics. He has also provided extensive service and leadership to professional societies including the Entomological Society of America, the Coleopterists Society, and a diversity of state and regional associations. Although his record of service is extensive, Young’s true passion lies in teaching. Former students were very vocal in their support for Young’s nomination for this award.
Brood XIII gets its own website!
Now that the solar eclipse has passed, the next big phenomenon will be our emergence of Brood XIII periodical cicadas later this spring. Since these insects emerge in Wisconsin every 17 years, you might only have a handful of opportunities to see them in the Badger State in your entire life. Despite having grown up in southeastern Wisconsin and turning 40 next year, I still have not witnessed an emergence myself and I’m really looking forward to this year’s activity.
Since there will be so much “buzz” about these amazing insects, I recently launched a new Wisconsin Periodical Cicada website: cicadas.wisc.edu. The site covers the biology, ecology, and distribution of these insects, with lots of photos, cool historical videos, and other resources. This winter, I dug through 150+ years of books, newspaper columns, university/government reports, and specimens in our very own Wisconsin Insect Research Collection to develop an updated map of Wisconsin reports. While the map on the website is an improvement over older ones, there’s still plenty to learn about the local distribution of these cicadas in the state. To that end, I created a community science project on the website (cicadas.wisc.edu/community-science/) for folks to submit their sightings from Wisconsin—it’s a brief fillable form and photos can be uploaded right from your phone, tablet, or computer. And feel free to stop by the diagnostic lab—I’ve got some new Brood XIII stickers to give away!

Where are they now: The sponsored cockroaches from the holiday party
Story by Helen Oker and Morgan Weissner, with special thanks to Victoria Salerno and Emma Terris
August Easton-Calabria’s Cockroach, “Isabel”: Isabel has had an exciting few months with the local bumblebees! Some say that Madagascar hissing cockroaches aren’t meant to be pollinators and aren’t meant to fly, but Isabel had a dream. Not only is she one of the first of her kind to feel the breeze in her setae as she flies on the back of her bumblebee friends, but she has also developed incredible coding skills (no one can debug code like she can!). Isabel has had a fascinating journey, and she has a bright future ahead of her!
Sean Schoville’s Cockroach, “Kafka”
Even when he doesn’t wake up on the right side of the bed, Kafka has made the most of the last few months. Kafka has always had a strong curiosity about genetics, but it wasn’t until he came to Russell Labs that he had the tools to further explore the field. Doing good RNA extractions is particularly difficult when they don’t make gloves for tarsal claws – but he makes it work! When asked about what he plans to do next, he says “I don’t know, but I know that if I can use a micropipette, I can do anything.”
Alyson Amenda’s Cockroach, “Dusty”: Dusty has been hard at work establishing a Human (or should I say Insect?) Resources department for the many six-legged inhabitants of Russell Labs. She has been taking a colony-minded approach to community enhancement. Longtime resident, the Colorado Potato Beetle, says “Dusty has exterminated so many of the issues I have been trying to deal with, I am so grateful for her help!” Whether she is scurrying around the building’s ecosystem or using all her six legs to type at unprecedented speeds, you can be confident that she is working hard to make an organized habitat for all.
Lab updates
Bick Lab
The Bick Lab has been busy! Computer science graduate student Dev Mehrotra presented the insect eavesdropper at both the Falling Waters Competition and the World Agritech Innovation Summit. Graduate students Helen Oker and Fletcher Robbins presented at the Entomological Society of America’s North Central conference. Helen also led the development of an insect model teaching tool which was successfully rolled out in the Principles of Economic Entomology class. Graduate student Lauren Glynn developed a large language model to assist with extension communications. Dr Emily Bick was granted a Draper TIFF award associative with the Insect Eavesdropper.
Additionally, Dr Bick is headed to Germany this month to speak at the Bayer headquarters as a finalist in the lab-to-field competition. In collaboration with biological systems engineer Dr Brian Luck, The second invention was accepted for disclosure by the Wisconsin Alumni Research Foundation, hopefully enabling heat mapping of insect pests via drone-mounted sensors in a field. We in the Bick Lab are launching the state of Wisconsin’s first insect pest text alert service, which currently has 200 practitioners signed up to receive information. These days, we are deep in preparation for our field season.
Crall Lab
The lab had a busy winter and is excited to be starting summer field research for the year, which will include research on pollinators in local crop systems (apple, cranberry, and cucumber), as well as projects on comparative social behavior across bumblebee (Bombus) species in Wisconsin, the effects of drought and plant-pollinator interactions, and effects of ash on pollinator visitations and plant fitness in California!
Two lab members – postdoctoral Fellows Dr. Olivia Bernauer and Dr. Matt Smith – will both be leaving the lab in August to start new positions. Olivia will be starting as an Assistant Professor in the Department of Biology at the University of Wisconsin-Eau Claire. Matt will be starting as an Assistant Professor in the Department of Biology at the Illinois Institute of Technology. Congratulations Olivia and Matt, and we are thrilled for you both to be starting the next chapters!
Recent awards and grants. Congrats to Victoria Salerno for being a finalist in the three-minute thesis competition, and to Anupreksha for winning second place for lighting talks at the University of Minnesota Plant Science Symposium. Congrats also to Gigi Melone on receiving an Integrative Biology Summer Research. The lab is also excited to be supported by a new grant from Organic Valley’s Farmers Advocating for Organic.

Gratton Lab
Eliza Pessereau successfully defended their MS thesis in Entomology and Agroecology. They will be presenting their work in a public talk on Monday, April 29 at noon in 150 Russell Labs.
Claudio Gratton spent the month of March at Wageningen University and Research in the Netherlands where he gave some lectures and ran a graduate workshop on “Bridging science to practice: Exploring and developing decision support systems for ecological intensification of agricultural systems”.
Jeremy Hemberger and Claudio were recently awarded money from the USGS Cooperative Ecosystem Studies Unit to start a long-term bumble bee monitoring program in the Upper Midwest. This project, focused primarily on the endangered Rusty Patched bumble bee, will establish a number of sites that are surveilled continuously for the next 4-5 (and hopefully more!) years. The aim of the project is to establish long-term occupancy and abundance measures of all species in the bumble bee community while also measuring the population health of target bumble bee species using genetic methods. These data can be used in species recovery efforts and in more targeted research questions by the Gratton lab and other interested research groups.
Guédot Lab
The Guédot Lab welcomed two new graduate students. Elizabeth Hrycyna and Emilie Parkanzky who both started in January 2024 on their MS degrees in Entomology. Elizabeth is working on assessing the impact of commercial nematodes on the red-headed flea beetle in cranberry. Emilie will expand the work conducted by previous MS student Mitchell Lannan on applying attract-and-kill as a management strategy for Japanese beetle in vineyards and will look into the presence and distribution across southern WI of the microsporidian Ovavesicula popilliae which is a biological control agent of Japanese beetle.
Mitchell Lannan, who is now the Forest Health Specialist for the Arizona Department of Forestry and Fire Management, had his article that was published in the Journal of Economic Entomology featured in Entomology Today on March 12, 2024 in the article “How luring beetles to field edges could reduce insecticide usage in vineyards”. Well done Mitchell!
We wrapped up our winter webinar series “Organic Commercial Fruit Production Strategies for the Midwest Webinar Series” in collaboration with colleagues at MN, IA, and IL and are planning field days for the spring and summer.

- How mosquito larva guts could help create highly specific insecticides. Did you know that the world’s deadliest animal is the mosquito? And Aedes aegypti is one of the most dangerous. This bug spreads viruses that cause dengue fever, which was recently declared as an epidemic in Puerto Rico. Research reports new molecules that label proteins in the unique, alkaline environment of the aegypti digestive system that could help scientists develop insecticides to fight back. – ScienceDaily.com
- Rusty-patched bumblebee’s struggle for survival found in its genes. The rusty-patched bumblebee, once common in the United States, has declined from about 90% of its former range. Researchers conducted the first range-wide genetic study of the endangered species to inform recovery efforts. – ScienceDaily.com
- Bees need food up to a month earlier than provided by recommended pollinator plants. Plant species which are recommended as ‘pollinator friendly’ in Europe begin flowering up to a month too late for bees, resulting in low colony survival and low production of queens. This research has quantified the decline in colony survival and queen production due to a shortage of early season food. Enhancing existing hedgerows with early blooming species has the potential to increase the probability that a bee colony survives from 35% to 100%. – ScienceDaily.com
- Honey bees at risk for colony collapse from longer, warmer fall seasons. The famous work ethic of honey bees might spell disaster for these busy crop pollinators as the climate warms, new research indicates. Flying shortens the lives of bees, and worker honey bees will fly to find flowers whenever the weather is right, regardless of how much honey is already in the hive. Using climate and bee population models, researchers found that increasingly long autumns with good flying weather for bees raises the likelihood of colony collapse in the spring. – ScienceDaily.com

- Sap beetles vs wind: What pollinates screw pines? Researchers have discovered the first species pollinated by sap beetles in the genus Pandanus, a group of palm-like plants native to the tropics and subtropics of Africa and Eurasia. The discovery overturned the long-held belief that these plants were pollinated by wind. The researchers also found that fragrant screw pines’ male and female flowers produced heat at night stably, making them the first such species in the family Pandanaceae. – ScienceDaily.com
- In flies, a single brain cell can drive multiple movements of the body. Motor neurons are the cells the brain uses to command muscles to act. Scientists typically thought of them as simple connections, much like the cables that link computers with their accessories. Now, in fly studies, researchers have discovered that single motor neurons can each direct an insect’s body to move in far more complex ways than previously thought. – ScienceDaily.com
