How environmental factors are pursued, analyzed and which behavioral responses are influenced? But also, how intra- and interspecific interactions could modify behaviors by changing gene expression? By using tools from chemical ecology and behavioral genetics, my own researches focus on social interactions and their adaptive impacts. So, my studies are based on insect behaviors (recognition, aggressiveness, foraging, parental care, sexual courtship) through the study of chemical communications and gene expression. ![Pheidole pallidula hunting]( "Pheidole pallidula hunting") Behaviors and genes expression are under several abiotic and biotic environmental factors which also include social environment. Chemical communication plays an important role in inter-individual interaction in insects and codifies part of the environmental and social information. To unravel communication mechanisms of insects and their evolutions, it is of primary importance to decrypt such chemical information. In more details, I explore questions on behavioral plasticity of insects and in particular in social insects: *What are the chemical signals and the genes involved? How environmental factors play a role? What are the consequences of the different reproductives/castes on social organization in insect societies? How such systems are maintained and evolved?* In social insects, the caste system allow the main factor influencing behavioral plasticity is the caste system which is linked to social organization and raised several questions ![R. flavipes in woods]( "R. flavipes in woods") ***Species studied*** To answers such questions, I study several insect models like termites, ants, earwigs, wasps (solitary and social) and drosophila. They all presents specificity and possess different advantages for my researches. Social insects like termites and ants are organized in complex societies with several social interactions. Nevertheless, eusociality (true sociality) appeared independently in Isopteran (termites) and Hymenopteran (ants, bees and wasps) which gives to termites unique specificities. Concerning drosophila, it is the most studied insect model and its genome is known since a long time, which allow to dissect in details the genetic pathways of its communication system. ![Pheidole pallidula soldiers and workers]( "Pheidole pallidula soldiers and workers") ***Main methods*** \- Chemical analyze and identification: gas chromatography (GC), mass spectrometry (GC-MS/GC-TQ), thin layer chromatography (TLC), liquid chromatography (HPLC), chemical extraction (SPME, SBSE, SHS, DHS, DMDS) \- Genetic expression: quantitative RT-PCR, in situ, RNA interference \- Experimental behavior: video-tracking, cross-linked reproduction, cross-fostering ![Termite biblio]( "Termite biblio") *Liens* ------- [Union Internationale pour l'Etude des Insectes Sociaux - Section Française]( [GDR d'écologie chimique]( [Canadian TV news on "foraging behaviour of *Pheidole pallidula*"](
