Professor Emeritus, Galen Dively and his colleagues have a new paper out in the Journal of Economic Entomology titled, “Sweet Corn Sentinel Monitoring for Lepidopteran Field-Evolved Resistance to Bt Toxins” The study demonstrates that the sentinel plot approach as an in-field screen can effectively monitor phenotypic resistance and document field-evolved resistance in target pest populations, improving resistance monitoring for Bt crops. As a direct result of Galen’s research, the EPA has proposed a number of changes to the way the agency monitors genetically modified crop technologies. This fall Galen presented his research at the Fall Entomology Seminar Series. Check out PhD students Darsy Smith and Veronica Yurchak's Seminar Blog summarizing that talk.
On a related note, a recent Maryland Farm & Harvest episode covered several stories on corn production, including a segment at the Beltsville Agricultural Research Center featuring Galen’s research on genetically modified corn.

Neonicotinoids are most commonly known to the public as a class of chemicals responsible for widespread pollinator decline. To growers they are a cheap means of dealing with historically difficult soil pests and are heavily used throughout the United States as a preventative measure. Given their prevalence, are the benefits enough to justify their use? Recent University of Maryland (UMD) entomology graduate Dr. Aditi Dubey, Hamby Lab, addressed this question and more in her exit seminar, summarizing five and a half years of research.
Hunting the Flesh Eating Screwworms: Dr. John Welch and an entomological career of adventure and service
written by: Graham Stewart, Meghan McConnell, Tais Ribeiro
On the past November 20th, Dr. John Welch, Liaison for Action Programs of International Services (APHIS) and co-recipient of the 2020 Scientist of the Year Award, brought to the Entomology colloquium his example of a successful entomological career outside of academia, sharing some of his adventures and the many roles he has occupied. Although Dr. Welch’s work has involved a variety of issues, over the years his main focus has been on eradication of the screwworm (Fig 1), Cochliomyia hominivorax (Diptera: Calliphoridae). The screwworm is a deadly, parasitic fly that feeds on the living tissues of warm-blooded animals. It has many nicknames, one being “man-eater”. It has been a problem for livestock and humans for decades, leading to major economic losses for farmers. Two entomologists Edward F. Knipling and Raymond C. Bushland, are known for pioneering successful eradication efforts through the Agriculture Research Service (ARS). They developed the sterile insect technique (SIT), a low dose of radiation to make the screwworms sterile. The flies are then raised in a lab and released in infested areas. These sterile males mate with the females and the eggs laid do not mature.

At the beginning of his Entomology Department exit seminar presentation, graduate student Dylan Kutz asked his zoom-viewing audience “Who cares about spiders?” and “Why study drainage ditches?” – two questions that immediately grabbed everyone’s attention. Over the past three years Dylan has proven himself to be an adventurous and fearless researcher – sampling agricultural cropland drainage ditches for spiders in order to ascertain how they may facilitate natural pest management practices by supporting spider populations.

Dr. Galen Dively, a Professor Emeritus in the Department of Entomology at the University of Maryland, has become a leading figure in the effort to monitor and mitigate resistance development to genetically modified Bt corn, primarily addressing the very destructive corn earworm. At this week’s colloquium, Dr. Dively presented on his work designing a new approach for monitoring insect resistance in Bt corn, as well as how this approach is changing the way genetically modified crop technologies are regulated by the EPA.
"Assessing the impacts of seasonal leaf litter disturbance on overwintering pollinators and natural enemies" earns grad student Max Ferlauto first prize poster at AGNR cornerstone event. Watch video to see how Max's work supports the college's initiative to improve human, animal, and environmental health.
Congratulations to AGNR Enterprise Challenge winners, Krisztina Christmon and her fellow teammates.
Krisztina and her team were challenged to, in a 3 week time span, come up with an idea to turn empty poultry houses in Maryland into something else. Krisztina said, “It was a short but intense 2 weeks of brainstorming and research. We wanted something that would be easy to set up, sustainable, novel and profitable." The team pitched a plan to the judges to use the empty poultry houses to address the dark reality of the US plastic crisis. “It is such a mounting issue in Agricultural that it already has a name for itself: plasticulture.”says Krisztina. Their award winning plan, she shares “[to] turn these facilities into an agricultural plastic washing-sorting-recycling facility. In addition, we would develop a technology to neutralize the chemicals (pesticide, fertilizer etc.) of wastewater and in the end product”
The team won the competition's top cash prize and a spot in the MD and National iCorp program where they will learn more about entrepreneurship and ways to make their idea come alive.
The Song of the Lacewings: A look into the unique mating call of the green lacewing and why their larvae fake their death.
Many people are fascinated about the diversity in nature, some are attracted by cichlids with various colors, others were allured by butterflies with different patterns. Katherine Taylor, a new Post-doc in the Fritz lab, was interested in the diversity of the lacewing mating songs.
For nearly the last two decades, STEM educators, particularly those in biology, have been moving toward a more active learning model for undergraduate courses. Dr. Marcia Shofner has been at the forefront of that effort at University of Maryland. Dr. Shofner is a Senior Lecturer in the Entomology Department, teaching several sections per year of Ecology and Evolution. Not only is this course often an early undergraduate’s first introduction to college biology, but it is often a Graduate Teaching Assistant’s first foray into teaching as well. At this week’s colloquium, Dr. Shofner shared a “peer through the lens” into designing and implementing an active learning course with the Entomology community.
In the spring of 2004, millions of 17-year cicadas emerged from the ground. They crawled over trees, houses, and cars. They molted leaving exoskeleton shells on every surface. Birds feasted. Squirrels gorged themselves. Newly planted trees suffered. Children tiptoed though carcasses on their way to school. Parents scraped goo off their car’s wheels. The air vibrated with the cacophonous sound of cicadas. Then they were gone. But next year they are coming back. Whether you anticipate it with dread or excitement, they are coming again.
In his colloquium presentation to the UMD Entomology Department, Dr. Mike Raupp, an emeritus entomology professor at the University of Maryland, brought us up to speed on the coming emergence of periodical cicadas. The last time Brood X, the 17-year cicadas local to this area, emerged from the ground, entomologists were in heaven. Dr. Raupp gave numerous talks around the country even ending up on Jay Leno’s late-night show to teach about the fascinating insect. He explained how 17-year cicadas are a great opportunity to get people interested in bugs. Next year, they may be even more numerous due to recent habitat restorations and improved tree cover.
Congratulations to Entomology’s Alys Jarvela and Leslie Pick whose paper was just published in Communications Biology. Their research showed that mosquitos lost a gene that is essential for survival in other insects without ill effects. They also found that a related gene stepped in and took over the lost gene’s role. This discovery represents the first time that scientists identified a gene that naturally evolved to perform the same critical function as a related gene long after the two genes diverged down different evolutionary paths.

Seven months into the global COVID-19 pandemic, Dr. Leslie Pick, department head of entomology, kicked off the department’s fall colloquium series in a way that’s become familiar; she muted the audience, thanked everyone for coming, and shared her screen.
Past colloquium speakers have talked about the latest research in entomology, but Dr. Pick talked about topics even more important: COVID-19 and racism. Addressing COVID, she took us back to March by reminding us that over a one-week period the department transitioned from normal research to working from home with severe research restrictions. When you’re working with live animals and cultures, however, this doesn’t mean hitting a pause button. The whole department mobilized to care for colonies of insects and live cultures on campus or bring them home. Bringing home wolf spiders, lady beetles, and mantises was a new adventure for many and even attracted the attention of Nature and NPR.
In a paper published in Genetics today (https://www.genetics.org/content/215/4/1027) Entomology graduate student Katie Reding (Pick lab) used CRISPR/Cas9 to make a genomic deletion of the white gene in the milkweed bug Oncopeltus fasciatus. The white gene was one of the first genes identified in Drosophila, over 100 years ago, where it is necessary for the red eye color of flies. Interesting, in Oncopeltus, white is necessary for pigmentation throughout the body but it is also necessary for organismal survival, as animals homozygous for the white mutations do not survive to adulthood. This is the first demonstration that CRISPR is effective in Oncopeltus. Methods Katie developed will be useful for researchers to test the function of other genes in this and related species.
Entomology's Mike Raupp weighs in on enormous wasps about to emerge en masse throughout the eastern half of the U.S. to hunt cicadas—and to worry people. They are black with caution-yellow markings and the size of a USB stick.
