Mon objectif est de comprendre le rôle et l’importance des odeurs et des médiateurs chimiques dans le fonctionnement et l’évolution des relations plantes-insectes. Je m’intéresse particulièrement aux aspects suivants : quelles sont les caractéristiques des odeurs et des signaux chimiques disponibles pour les insectes ? Quelle est l’activité biologique de ces molécules (réponse comportementale des insectes) ? Dans quelle mesure et à quel(s) niveau(x) ces interactions chimiques jouent un rôle dans le fonctionnement et l’évolution des systèmes plantes-insectes ?
