OverviewAI-generated summary
David E. Dussourd studies insect behavior and physiology, with a focus on herbivorous insects and their interactions with plants. His research investigates the mechanisms by which insects, particularly caterpillars, modify plant tissues and how these behaviors relate to the plant's defensive chemistry and structure. Recent publications explore the role of secretory canal architecture in plant leaves in influencing insect feeding patterns and the use of caterpillar saliva to modify plant petioles. Dussourd also examines the energetic costs associated with specific insect feeding behaviors, such as girdling. His work contributes to understanding the complex relationships within food chains and the ecological roles of insects. He has published 29 works, which have been cited 1,795 times, and holds an h-index of 18. He collaborates with Matthew E. Gifford.
