Resumen:
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.
