The aromatic species in the surrounding areas to crops may be important sites of refuge and other behaviours of the fruit flies. The importance of volatile oils from these species as infochemicals signals remains unknown. The aim was to determine the chemical composition of essential oil (EO) from B. spartioides and evaluated their effect as attractants of females of C. capitata. Plants were collected in Angaco, San Juan, Argentina. EO were obtained by hydrodestillation and the chemical composition was determined by GC-MS. Bioassays were carried out in a Y-tube olfactometer. The essential oil of B. spartioides showed gamma-terpinene, sabinene and beta-pinene as the main compounds accounting for 81.13% of the oil. Significantly more females visited the arm with the essential oil compared to the control arm. The results stress the importance of continuing studies on volatile and EO components as infochemical agents of the fruit flies. Acknowledgements. PICT´07-01468, PIP´08-0407, UNSJ-I905.
