Abstract

Plants respond to stress or damage by releasing volatile compounds, primarily for defense purposes. These volatiles function as signals for di! erent interactions of the plant with its environ- ment. In this study, the volatile chemical pro" le of healthy Garcinia mangostana L. (mangosteen) leaves was compared against leaves infested with the scale insect, Aspidiotus rigidus Reyne (Hemiptera: Dias- pididae) through solid phase microextraction (SPME) coupled with gas chromatography- mass spec- trometry (GC-MS). Analyses revealed that leaves emit the terpene kaur-16-ene in response to A. rigidus infestation. Kaur-16-ene is a precursor of gibberellin, a plant hormone for growth and development. The results suggest that the emission of kaur-16-ene in infested G. mangostana may play a role relevant in increasing the resistance of the plant towards infestations by herbivores.
