Research Interests

Cotesia congregata

I am interested in complex evolutionary systems. Often, evolution is best understood by incorporating multiple approaches, not just a focus on molecular genetics or ecology. Parasitoid insects are particularly interesting to me because they are fully dependent on their hosts, but often also on their host's foodplant. Parasitoid behavior, host immunity, plant chemical compostion, and molecular genetics all play a role in the evolutionary process.

My current research uses Cotesia congregata, a parasitoid of sphingid larvae, as a model to study the patterns of speciation among parasitic wasps. Parasitic wasps are highly diverse, but relatively little is known of the mechanisms driving their diversity. I combine work at multiple layers from behavior and ecology, to molecular genetics of their symbiotic polydnavirus to understand the mechanisms leading to speciation. I have worked extensively on breeding crosses of different host-foodplant complex sources of C. congregata to identify patterns of reproductive isolation. I have also made comparisons of response to female pheromone and analyzed differences in male courtship songs. We are currently collaborating with USDA-ARS on molecular differentiation of the symbiotic polydnavirus among the different host-foodplant sources of C. congregata.
