We want to better understand how chemical signals (food, sex, environment) are detected by insects and how they contribute to the adaptation of insects to their environment, for example in finding, recognizing and selecting a sexual partner.This involves describing behavioral, physiological and adaptive responses of insects to the environment and to other insects, as well as studying signalization pathways involved in the production of pheromones, in fertility or in modulating other behaviors.

Our different projects combine experimental approaches using behavioral observations, physiology and electrophysiology studies, cytological and biochemical observations. We mainly study drosophila species belonging to the melanogaster group, on which we study sensory and hormonal factors which play a role in reproduction, sexual partner selection and feeding. We also study feeding and reproduction in Hermetia illucens, the black soldier fly.
