Leveraging the circadian clock to reprogram insect diapause
Jacob Dayton
Ph.D. Candidate in Biology, Tufts University
Abstract: The timing of insects’ daily behaviors (feeding, movement) and seasonal development (diapause, migration) affects their population dynamics and distribution. Despite the implications for insect conservation and pest management, the genetic mechanisms underlying variation in timing are poorly understood. To fill this gap, I will report how manipulating the circadian clock gene function alters the daily activity and larval diapause of the European corn borer (Ostrinia nubilalis), a widespread corn pest.
Why nothing in ecology or evolution makes sense, except in the light of the other: Testing Eco-Evo Dynamics Through the Beak of the Red-Shouldered Soapberry Bug
Dr. Mattheau Comerford University of Massachusetts Boston
Abstract: Eco-evolutionary dynamics refer to the cyclic interaction between evolution and ecology, where an organism’s ecological interactions can influence the evolution of a trait, and conversely, evolutionary changes can impact ecological interactions. Due to the often contrasting time scales at which ecology and evolution operate, the rapid life history of insects offers a unique opportunity to study these crucial feedback loops. In this context, I have utilized the red-shouldered soapberry bug (Jadera haematoloma) to investigate eco-evolutionary theory from both perspectives. Firstly, I explored a less-studied form of evolution known as spatial sorting. Secondly, I described the first known example of a hemipteran insect acting as both a plant-pollinator and a seed-predator.
NOTICE: We will be holding hybrid meetings to accommodate audience members from around the world.
For those able to attend, we will have an informal dinner at 6:00 pm at Cambridge Common Restaurant with the speaker, followed by our formal meeting (~7:30 – 9:00 pm) in room MCZ 101 of the Museum of Comparative Zoology (there will be signs to help direct). The meeting will begin with club announcements, followed by a 60-minute presentation by the invited speaker and Q&A. Membership is open to all.
