Maggie is named a 3MT winner in the 2021 3MT Campus-Level Video Competition!
Maggie produced a video entitled, "Dragons on the farm: A novel approach to determining dragonfly diet in agroecosystems," as part of the 3MT (three minute thesis) competition at the University of Maryland. This program is part of a global competition held at many universities. She was first selected in the top 20 winners at UMD, and now has been selected as one of the top 6 winners! The video describes her Masters thesis research: "Dragonflies are obligate predators as adults and can be found in agroecosystems. However, their role as predators of agricultural pests is largely unknown. Using novel molecular methods, we can investigate their diet breadth by sampling their feces and performing sequencing to detect prey DNA." You can view the video here. (Posted May 15, 2021)

Alina's research on molecular gut content analysis of the spotted lanternfly published!
We are pleased to make Alina Avenesyan's research available in the journal, Insects, in an article entitled, "Use of molecular gut content analysis to decipher the range of food plants of the invasive spotted lanternfly, Lycorma delicatula." Using field collected nymphs, the paper (1) describes a protocol for using molecular markers for food plant identification, (2) compared the ingested plant DNA to the plant on which the lanternfly was collected, and (3) reported on the spectrum of plants found in the gut. In the majority of sampled nymphs, the gut contents did not reflect the plant on which the nymph was collected. Food plants included both native and introduced plants, as well as woody and non-woody plants. The technique will be useful for predicting host plants with range expansion. The article can be found here. (Posted April 22, 2020)

Alina's article in PlosOne on spotted lanternfly morphology published!
We are pleased to publish our recent research on "External morphology and developmental changes of tarsal tips and mouthparts of the invasive spotted lanternfly" in PlosONE. The article describes the morphology of the lanternfly associated with host plant use through the nymphal stages to the adult: the tarsal tips (arolia and tarsal claws) and mouthparts (stylets and labium).The increase of stylet length from nymph to adult stages, as well as indentations on mandibular stylets, may be associated with significant changes in host plant usage. Arolia size only increased from 1st to the 4th nymphal instars; no additional increase was observed to the adult stage. Attachment ability and host plant preferences may be affected by the plant surface profile. Overall, our study will be useful for investigating and predicting lanternfly host range. The artice is available online and here. (Posted January 3, 2020)

Our graduating undergraduate receives high honors for her Entomology thesis!
We are very proud of Claire Weber, who has been working in our lab the last year and a half. She graduates this semester, and along the way she wrote and defended an honors thesis for Entomology, entitled “Functional Trait Assemblages in Lotic Stream Communities in Relation to Stream Flashiness.” Claire combined two large data sets from USGS and MBSS to compare the traits of insects found in stream communities to the amount of flashiness experienced by the stream. She identified a clear relationship between stream flashiness (frequent and rapid fluctuations in stream discharge) and the traits of insects. Insects in flashy streams had faster seasonal development, greater ability for adults to exit the stream, weaker swimming ability, and smaller size at maturity, among other traits. Claire will spend the summer in Argentina and Costa Rica, before moving to the University of Utah to pursue graduate studies in geography. (Posted May 20, 2015)

New publication in PLOS ONE on climate change and migration of potato leafhopper!
