Complexity at multiple scales: how do flower strips and crop plant structure affect predator-prey dynamics and biological control efficacy in field-grown lettuce?
My research is examining whether sweet alyssum strips can promote natural enemy diversity and abundance in commercial lettuce fields in Québec, and how this may promote aphid suppression. It is also examining how these flower strips affect ecological interactions among predators and their prey within the crop, including intraguild predation and apparent competition, and how lettuce plant architecture may also influence these interactions.
