Abstract: Semiochemicals are involved in mediating a wide range of insects behaviors, from intraspecific communication (pheromones) to the location of food and oviposition source (allelochemicals). Here we explore the chemical ecology of the stink bug Bagrada hilaris (Heteroptera: Pentatomidae), a pest of brassicaceae native from Africa and Asia and invasive in USA. At intraspecific level, observation evidenced that male volatiles, mainly constituted by (E)-2-octenyl acetate, attract females conspecific. At interspecific level it was observed that B. hilaris exploit specific key plant volatiles to locate preferred host plant. One of these volatiles was identified as a diterpene hydrocarbon of new observation and named brassicadiene
