Congratulations to Environmental Science and Policy major, Maggie Tan (Palmer Lab), who successfully defended her entomology honors thesis last week. Her thesis entitled, “Changes in Hydrology and Water Quality Resulting from a Regenerative Streamwater Conveyance System in Campus Creek", received honors. Under the supervision of Michael Williams, her honors thesis investigated how Campus Creek’s regenerative stream conveyance restoration project influences the water quality of the Chesapeake Bay. Maggie used hydrological and water chemistry data to document changes that occurred in Campus Creek, on the north side of campus, when step pools were placed in the stream in 2019. Their data provides a preliminary picture that RSC may reduce runoff as well as nutrient and sediment concentrations.
It has been wonderful having Maggie in the Entomology Honors Program. She graduated from UMD Environmental Science and Policy program this Spring with a concentration in Geosciences and Restoration and minoring in Geochemistry. Maggie has plans to start graduate school this fall in Arizona.
Despite challenges presented, Entomology kept teaching, kept learning and kept working during the spring 2020 semester. Check out research & teaching during COVID, promotions, publications, awards, defenses, workshops and much more.
Does where you breed change how you live? Differences in host seeking and chemosensory gene expression between above- and below-ground mosquito populations
written by: Mike Nan, PhD student, St. Leger lab and Dylan Kutz, MS student, Lamp lab
Anna Noreuil, an M.S. student in the Fritz Lab in the Department of Entomology at the University of Maryland, has been studying host-seeking behavior and differential chemosensory gene expression in above- and below-ground Culex pipiens for her master’s research. Cx. pipiens (Diptera: Culicidae) is a mosquito found in the northern regions of the U.S. and is also found in urban and suburban temperate areas around the world. Cx. pipiens is the primary vector of West Nile virus (WNV), a mosquito-borne disease that affects the nervous system, in the Northeastern US. Oddly, although there is only one species known as Cx. pipiens, two “bioforms” of the species exist which are morphologically indistinguishable but genetically, physiologically, and behaviorally different: “Cx. pipiens form pipiens” and “Cx. pipiens form molestus.” Cx. pipiens form pipiens differs from Cx. pipiens form molestus in three distinct ways: (1) it breeds in above-ground habitats, (2) it requires blood meals for egg production, and (3) it prefers avian hosts over humans (Figure 1). However, these two “bioforms” readily hybridize or crossbreed and as such they are both classified as the same species (Figure 2).
Dr. Bill Lamp is seeking an undergraduate student, sophomore or junior, to join his lab as a part-time intern, 10-15 hours/week, to focus on molecular approaches applied to the study of plantinsect interactions of an invasive insect, the spotted lanternfly. The position requires a current University of Maryland student who has experience with molecular biology and basic molecular techniques, or has a strong desire to learn them. The student will use molecular techniques to aid in the identification of host plants of the spotted lanternfly using DNA barcoding of their gut contents. Entomological experience is not required, but an interest in or willingness to learn about insects is useful.

Entomology faculty member Dr. Kelly Hamby has been promoted to the rank of Associate Professor with tenure effective August 2020!
Since joining the UMD Department of Entomology in 2014, Dr. Hamby has developed a nationally and internationally recognized research and extension program that focuses on characterizing spotted wing drosophila's interactions with yeast and fruit rot microorganisms and developing cultural control tactics for this invasive pest. Hamby’s lab is also evaluating the pest suppression benefits and non-target impacts of neonicotinoid seed treatments in mid-Atlantic grain crop rotations. In 2017, The Entomological Society of America recognized Dr. Hamby with the Early Career Professional Extension Award for her demonstrated contributions to entomology.
Giant gypsy moths could bring 'serious, widespread damage' to the US. "Were it to become fully established and spread widely, it would affect forests and landscape trees and shrubs in the invaded range," says Prof. Emeritus Mike Raupp.
As we lead up to Spring 2020 graduation, celebrating the success of our entomology grads and honors undergrads, UMD Today reminds us, the first woman to graduate with a four year degree shared their interest, a passionate pursuit of knowledge about the natural world. Discover more about entomology major Elizabeth Hook and how she helped set the stage for future generations to follow.
Entomology's Todd Waters is recognized as Dean's Outstanding Employee! A well deserved recognition, for sure. Todd's creativity & enthusiasm for entomology engages audiences of all backgrounds -community members, staff, students, faculty, etc - inspiring them to want to discover more about insects. Congrats, Todd!
Congratulations to Public Health Science at University of Maryland, College Park student, Rebecca Kaminsky (Fritz Lab), who successfully defended her entomology honors thesis, "Larval rearing conditions conducive for Aedes aegypti autogeny expression and theoretical population growth." She received high honors for her research into autogeny - the ability of a mosquito to lay eggs without a blood meal. Becky found that increased larval nutrition was consistent with increased phenotypic expression of autogeny.
It has been wonderful having Becky in the Entomology Honors Program actively engaging in research these last few years. We wish her all the best in her future pursuits!
What affects will the asian giant hornets have on local and national ecosystems. Should we worry about asian giant hornets in the DMV? 1A, WJLA, WTOP and WUSA9 reach out to Professor Emeritus Mike Raupp for answers. In short, "Here in Maryland, in the DMV, we've got a bit of time," he says. See full interviews to learn more:
