The antibacterial and insect-repellent activities of the essential oils (EOs) from Argentinianmedicinal plants Azorella trifurcata (Gaertn.) Pers., Senecio cfr. oreophyton J. Remy andSenecio cfr. pogonias Cabrera, were investigated. All EOs showed good repellentproperties against Triatoma infestans Klug, the vector of the Chagas disease, with percentrepellence values between 60% and 70% at 24 hours compared with positive control N-Ndiethyl-m-methylbenzamide (DEET) and moderate activity against the bacteria tested withminimum inhibitory concentrations (MICs) values between 31.2 and 2000 μg/ml. TheAzorella trifurcata, Senecio pogonias and S. oreophyton EOs, obtained byhydrodistillation, were characterized by GC-FID and GC/MS analyses. Spathulenol(38.2%), myrtenyl acetate (8.4%) and α-terpineol (4.5%), limonene (9.8%) and α-thujene(5.4%) were the main constituents in the EO of Azorella trifurcata. The Senecio pogoniasand S. oreophyton EOs are characterized by a high content of monoterpenes hydrocarbons
