The Insect Physiology & Behavior Research Group (IPBRG), headed by Spence Behmer, studies insect physiology and behavior, including their ecological and evolutionary bases. Our approach is "bottom-up", with an emphasis on using individual behavior as a tool to understand physiological and higher-level processes. Recently we have also begun to use sequencing approaches to better understand physiological processes. Our lab pursues three broadly defined areas of research:


     1) physiological ecology

     2) insect sterol (cholesterol) biology

     3) mechanisms of learning


We use a number of different insects in our research, including grasshoppers, caterpillars, ants, Drosophila, and insects with sucking mouthparts (hemipterans).

February (2017) - Spence is attending the Gordon Research Conference on
     Plant-Herbivore Interactions (Ventura, CA). He is the Vice Chair for the 2017
     meeting, and the Chair for the 2019 meeting.

January (2017) - Our paper on nutrition mediating insect susciptibility to Bt toxins is now
     avialable (published in Scientific Reports)! We believe this is a very important paper.

December (2016) - We have another paper out (in the Journal of Insect Physiology) related to
     our NSF-funded life-history trade-off research. This paper is on lipogenesis across different
     nutritional environments.

November (2016) - Our paper on nutrition as a neglected factor in insect herbivore
     susceptibility to Bt toxins is out (Current Opinion in Insect Science).

October (2016) - Congratulations to Richelle Marquess on a succesful thesis defense!

September (2016) - Spence will be attending the XXV International Congress of
     Entomology. Spence is giving an invited locust talk, and an update on his USDA funded
     rearch at a USDA workshop for PDs.

August (2016) - Another busy semester begins...Spences is teaching three classes...General
     Entomology (ENTO 201), Insect Physiology (ENTO 306) and Physiological
     Ecology (EEBL 601).
