Chemical communication in insects

My research field is chemical communication in phytophagous insects. Through sensory physiology and behavior I am aiming to understand how insects localize a resource by discriminating and orienting to olfactory cues in their environment. Although pheromones constitute a very efficient and specific communication system in insects, interactions between signals are omnipresent as illustrated in several of my former publications.  First, communication between sexes is often multimodalitary. Exchanged signals may belong to different sensory modalites and be produced by the same species. In sting bugs (Pentatomidae) vibratory female songs enhance the release of the pheromone by males (for instance Miklas et al, 2003). Second, pheromone perception can be impeded by anthropic pheromone analogs (reviewed in Renou & Guerrero, 2000; Bau et al 1999, Quero et al 2004). Third, interactions may involve natural semiochemicals produced by different other species. For instance, the perception of volatile plant components increases the response of palm weevil to their aggregation pheromone (Said et al, 2005).
Thus, the response any chemical signal including pheromone is less determined as generally admitted but always influenced by the sensory context. My current researches aim to understand how the odor environment, and more specially the volatile organic compounds released by plants may modulate the responses of male moths to their sex pheromones. Using a combination of electrophysiological (Party et al 2009, Rouyar et al 2015, Dupuy et al. 2017) and behavioral aproaches (Party et al, 2013) I am analysing the sensory coding of, and the orientation behavior to,  pheromone  signals.
