written by: Lasair ni Chochlain, Eric Hartel
​

​Addressing the varied needs of graduate students as not only learners but also researchers and teachers is a complex job. The University of Maryland and the Department of Entomology are doing their best to tackle this issue head on in 2023. To learn more about how the disabilities of graduate students are accommodated at UMD, we invited the Director of Accessibility and Disability Service (ADS), Tessa Cahill, to come to the Entomology Dept. colloquium to present “Disability Compliance and Accommodations: A Graduate Student Experience.” Tessa is the inaugural director of ADS, which is currently going through a period of growth and expansion to better serve the campus community. These changes are the result of an an external review by the Association on Higher Education and Disability (AHEAD) and support from UMD’s Administration that has led to ADS hiring more full-time staff and expanding their reach across many departments. By embracing this review and the changes ADS has made, the University of Maryland has been able to provide a significant increase in support. Improved communication between counselors, students, and faculty is also helping to standardize and improve the quality of services offered. Tessa first spoke about “how we got here” on a national level and then about the role and services of ADS on the university level.

Pick Lab expands the genetic toolkit for Hemiptera model systems

3/17/2023

 
Congratulations to Entomology graduate students Katie Reding and Minh Le, from the Pick lab, for their publication  "Genome editing of the vermilion locus generates a visible eye color marker for Oncopeltus fasciatus" in Scientific Reports. The study used CRISPR/Cas9 genome editing to generate an eye color mutant in Oncopeltus (Of). Bugs homozygous for mutations in the Of-vermillion gene are viable, fertile and have bright red rather than black eyes.  This is the first visible, genetic marker for this species, paving the way for development of additional genetic tools in this emerging model system for Hemiptera. In addition, these studies mapped Of-vermillion to the X-chromosome, the first gene to be mapped to a chromosome in this species. Finally, experiments using RNAi showed that knocking down the Oncopeltus ortholog of the rosy gene (encoding xanthine dehydrogenase) in Of-vermillion mutants changed the body color from orange-red to yellow, thus identifying a second candidate gene useful as a visible marker.

UMD Entomology Research-In-Progress: From the lab to the Field

3/9/2023

 
​Research-In-Progress talks are important opportunities for entomology graduate students to develop the communication skills necessary to become researchers in entomology and related disciplines. At the first research-in-progress talks of the spring 2023 semester, three graduate students presented their research, which cover different subfields of entomology: Theresa Menna, a 2nd-year Biological Sciences-CBBG PhD student in the Fritz Lab, Minh Le, a 2nd-year Entomology PhD student in the Pick Lab, and Max Ferlauto, a 4th-year Entomology PhD candidate in the Burghardt lab.

​Every spring, visitors flock to Washington, DC, to see over a thousand Japanese cherry trees in full bloom along the Potomac River. This ephemeral event draws massive numbers of viewers and concludes once the trees have shed their petals, sometimes just a week after blooming. We don’t often think about petals after they’ve fallen, but recent research suggests that these petals are more than just visually pleasing. Dr. Rebecca Hale is an urban ecologist who leads the Watershed Science Lab, a team focused on investigating urban stream dynamics to understand how cities can develop more sustainably. Dr. Hale and her team have recently found evidence that petals from flowering trees can have a tremendous impact on nutrient levels in surrounding water systems. Even in urban settings, these water systems are a foundational component of the ecosystems we rely on.

Hooks Lab & Extension evaluate French marigold as a border insectary plant

2/21/2023

The beautifully bright French marigold with its yellow, orange and mahogany blooms proves to be a bit too attractive to beneficial arthropods surrounding sweet corn fields. During the 2021 field season, researchers in the Hooks Lab and UMD Extension were busy, “Evaluating French marigold as a border insectary plant for the enhancement of beneficial arthropods in sweet corn plantings.” They found that while the marigold plants were indeed attracting beneficial arthropods such as encyrtid wasps and lady beetles, the beneficials remained near the marigold strips rather than dispersing throughout the sweet corn plots. The authors concluded that “when used as a border insectary plant, marigold may not improve biological control through predation and parasitization of economically important insect pests in sweet corn plantings”. Moreover, in the current study, marigold may have functioned as a natural enemy sink by luring natural enemies from sweet corn border rows.

[Seminar Blog] The string that holds it together: Ecoinformatics

2/3/2023

 
written by: Ebony Michelle Argaez
​

​Big data is the fuel of the 21st century, it is a part of our everyday lives; we produce and consume it. One example is the use of various types of data acquired from social media apps that are then used to deliver ads to targeted audiences. Yet, big data is also used in academia, health, science, and government for addressing research questions.
 
What is big data? Big data can be measured by its volume, variety, and velocity. Big data contains high volume in the form of many individual observations. Variety refers to many attributes associated with these observations. Velocity is the repetition of that volume and variety across some other dimension (e.g., time or populations). When preexisting big data sets are used in ecological studies, it is called ecoinformatics [1]. Dr. Michael Crossley, an Assistant Professor and Agricultural Entomologist in the Department of Entomology and Wildlife Ecology at the University of Delaware, uses ecoinformatics to understand how insect ecology is affected by changes in agricultural landscapes.

UMD Entomology Research in Progress: Extension in Beekeeping and Agricultural Contexts

1/6/2023

 
written by: Taís Ribeiro and Brendan Randall
It is crucial for graduate students to learn how to design and execute scientific research. Using this research as an informative tool that affects both the livelihoods of people and addresses public needs is essential to communicating science. The ongoing educational partnership between the public and scientists is known as extension and it is one of the pillars of the Department of Entomology. 
​

At the first Entomology Research in Progress Seminars, we heard about the work of two researchers that not only perform scientific research but are actively involved in the dissemination and application of their research to solve problems faced by growers and the public. The postdoc Dr. Nathalie Steinhauer and her work in extension in Beekeeping operations, and the PhD Candidate Maria Cramer, who works in agricultural environments. Both of these researchers are passionate about teaching and learning from stakeholders by showing their scientific results and seeing how applied science affects people’s lives.

[Seminar Blog] Arthropod-Disease Vectors: Remote Sensing Data Resolution and Entomological Indicators for Better Understanding micro- and macrohabitats (Dr. Mohamed Sallam)

1/6/2023

 
Mohamed SallamPhoto Credit: Mohamed Sallam
written by: Megan Ma
This week’s colloquium speaker, Dr. Mohamed Sallam, is a disease and arthropod vector ecologist who has worked in a variety of positions. His previous appointments include working as a research scientist for developing integrated pest management programs, senior analyst at USEPA (United States Environmental Protection Agency), and entomologist for the U.S. Navy. His background has led him to a position in Bethesda, MD as an Assistant Professor at Uniformed Services University (USU), where he is mentoring students and facilitating safer conditions in deployed military environments and U.S. military bases. Specifically, he is seeking ways of preventing disease transmission by developing models to reduce arthropod-disease vector-host contact. This can include efficiently treating uniforms – identifying regions of the body that are more likely to be targeted by mosquitoes minimizes the cost of treating full uniforms while maximizing the protection of high-risk areas of vector-host contact. To consider the full range of environmental and public health hazards, Dr. Sallam emphasizes the importance of understanding micro- and macrohabitats. This begins with research that can link models with the biology of your organism of interest.

Flower
written by Leo Kerner
We know that pollinators play a vital role in the health of every agroecosystem, but how can the agroecosystem benefit pollinators? Kathleen Evans, a PhD student in the Department of Entomology at the University of Maryland, is attempting to figure this out. Working in the Esp
índolaLab, Katy is focused on plant-pollinator interactions and loves to engage with the public informing them of the importance of insects. She came to speak at our colloquium about her most recent project on floral diversification and its effects on beneficial arthropods and ecosystem services among edamame. Previously, Katy has worked on pollinator health in agroecosystems and sustainable honeybee management practices, and now her work takes a closer look at understanding plant-insect interaction in agroecosystems.

New Club has Insect Terp population on the rise

1/3/2023

 
Insect Collecting, pinning and zoophoto credit: Athanas
In Fall 22 a new club for insect-lovers formed on UMD’s campus, Bug Club. While there has long been interest in forming an undergraduate community group around arthropods, the First Look Fair really cemented the case that there was an abundance of excitement around forming a club. Sophia Athanas, undergrad and president of the club, said that at the Fair she, “noticed that students were very interested in arthropods and entomology (especially when giant millipedes were brought out!). However, many students either couldn’t fit any classes into their schedule or didn’t have the time to participate in extra academic activities, such as the honor’s thesis or minor. Forming Bug Club would solve this problem by providing a low-stress, no-commitment opportunity for students with even the smallest interest to see what entomology is like!”

Today’s Lab-Raised Honey Bees have shorter life span

12/22/2022

 
PhD student Anthony Nearman and Associate Professor Dennis vanEngelsdorp discovered that life spans of lab-kept honey bees are 50% shorter than they were in the 1970s.  The College talks to Anthony about this latest paper:

“When I plotted the lifespans over time, I realized, wow, there’s actually this huge time effect going on,” Nearman said. “Standardized protocols for rearing honey bees in the lab weren’t really formalized until the 2000s, so you would think that lifespans would be longer or unchanged, because we’re getting better at this, right? Instead, we saw a doubling of mortality rate.”

Check out the full AGNR press release for more about the study and implications of the findings. ​

Welcome new faculty member - Dr. Niranjana Krishnan

We are very pleased to announce that Dr. Niranjana Krishnan will joining the Department of Entomology as an Assistant Professor and Extension Specialist this coming Spring 2023. Niranjana joins us from the Missouri University of Science and Technology. Her work focuses on invertebrate toxicology and risk assessment. In her current research project Niranjana employs the adverse outcome pathway (AOP) principle to estimate the risk of pesticide exposures to insects, particularly species of conservation concern. This is being undertaken via three research themes that incorporate in vitro, in vivo, and in silico methods - AOP development from molecular initiating events to organismal effects, AOP development from organismal to population level effects and AOP employment to inform interspecies extrapolation. When not in the lab Niranjana enjoy reading and writing about toxicology (check out her blog EnTox Simplified), visiting National Parks, hiking on trails with her husband & dog and volunteering for initiatives that help teach science and promote diversity and inclusion. Please join us in welcoming Niranjana to the Department!

The College talks to Dr. Espíndola about latest paper:

​Climate change is taking a serious toll on insects, UMD Entomology's Anahí Espíndola and dozens of scientists from around the world warned in a new paper published by the Ecological Society of America.

“We need to realize, as humans, that we are one species out of millions of species, and there's no reason for us to assume that we’re never going to go extinct,” Anahí said. “These changes to insects can affect our species in pretty drastic ways.”

written by: Ben Burgunder & Eric Hartel
​
How can modeling and mathematics inform our research of macroevolution? Towson University professor Dr. Daniel Caetano visited the University of Maryland's entomology department to deliver a lecture on his many research interests. Dr. Caetano explores evolution through mathematical modeling and novel approaches to phylogenetic comparative methods. Phylogeny is the scientific approach to understanding the evolutionary relationships between groups of organisms and phylogenomics is the application of genomics to phylogenetics research. Dr. Caetano explained that his research is supported by two pillars: trait evolution and species diversification. He discussed two examples of developing novel methodology from published, publicly available datasets.
