Ryabov has pub out in Frontiers in Insect Science on vector-pathogen interactions

10/18/2022

 
Varroa mites and viruses they vector are leading causes of honeybee losses. University of Maryland researchers Drs Eugene Ryabov (Bee Lab) and Zachary Lamas (Hawthorne Lab) team up with U.S. Department of Agriculture to study varroa mite infectiousness and the effect of the vectored viruses on varroa survival. Last month they published their findings in Frontiers in Insect Science entitled, “The vectoring competence of the mite Varroa destructor for deformed wing virus of honey bees is dynamic and affects survival of the mite.” The authors hope this work will provide new insights into the varroa mites' impact on colony disease and ways to manage it.

Publication out in SciReports on gut microbiome of cicadas - Co authored by Raupp

10/18/2022

 
University of Maryland PhD candidate Kyle D. Brumfield and Drs. Rita Colwell and Michael Raupp, teamed up with colleagues from the University of Connecticut-Storrs, University of Connecticut-Hartford, University of California Berkeley, and EZbiome, Inc. to explore the rich diversity of the gut microbiome of periodical cicadas. For those interested in learning more about their research into these remarkable insects, check out publication out this week in Scientific Reports.

Raupp chats Ants w/ the Weather Channel

10/18/2022

 
Prof Emeritus Mike Raupp tells the The Weather Channel yes, ants are indeed abundant, reaching every continent except for Antarctica. "They outweigh birds and all wild mammals which is is simply a huge huge amount of mass" Raupp says. & not only are the sheer # and distribution of ants amazing but so is the extraordinary contributions ants make to our planet.

[Seminar blog] How do insects stay hydrated in the heat?

10/18/2022

 
written by: Darsy Smith and Benjamin P. Gregory
​
​How do insects that live in dry environments like deserts keep from drying out, and how might these adaptations help them adjust to our constantly changing world? For our first colloquium of October, the Entomology Department welcomed Dr. Henry Chung, an assistant professor at Michigan State. Dr. Chung’s research investigates the genetic mechanisms underlying insect adaptations to different environmental conditions, particularly dry ones. Just like humans, insects need water to live their lives, so making sure they don’t dry out–or
desiccate–is vital to their survival. So how do insects that live in hot and dry conditions prevent desiccation? One of the most important pieces of an insect’s defense against desiccation is its epicuticle, the waxy top layer of its exoskeleton, and the chemical pieces that make up this epicuticle, called cuticular hydrocarbons (CHCs).

Mariom Adriana Carvajal takes a second look at genus Steatoda

10/3/2022

 
Spiders of the genus Steatoda, known as false black widows, have a resemblance to the black widow but are less harmful. However, around the world, there has been an increase of reports that this "less harmful" genus has been causing quite a debilitating bite. Heightened public concern has researchers, like grad student Mariom Adriana Carvajal (Shultz Lab), revisiting this genus. Mariom has been studying 1 of the 7 species found in Chile, taking a second look at its characteristics and its distribution. Today, Mariom and collegues published some of that work in Revista Chilena de Entomología, entitled, “A new record of Steatoda porteri in Chile.” Their findings show that although Steatoda porteri has extended its range, it remains outside urban areas for now. ​
