• Resumen

  • The biological activity of peel essential oils of two Sicilian cultivars of C. limon, �Interdonato� and �Lunario�, was investigated by electrophysiological recordings (EAG) and field trials on Ceratitis capitata (Wiedemann) (Diptera Tephritidae). The EAG data showed a remarkable dose-response relationship and a low activation threshold dose (10-3M) for both essential oil extracts. In field tests, essential oils showed a good repellent and antiovipositional activity on �Navelina� oranges, and in particular the essential oils of �Lunario� provided the same results of kaolin. Potential applications of essential oils from C. limon cultivars against C. capitata in organic farming are discussed.
