The olive fly is a serious pest in the Mediterranean. Copper is used to manage it in organic groves, but its use is restricted. Therefore alternative products should be utilized. This work carried out in 2007-2008 in three Apulian olive groves on Coratina and Termite di Bitetto cultivars aimed at testing: i) copper oxichloride, kaolin and propolis effectiveness, ii) their influence on oil quality, and iii) their residues of trace elements in olive fruits and oil. Infestation level and quality criteria such as acidity, peroxide index, K232, K270, .K, and panel test were evaluated. Trace elements were determined by Inductively Coupled Plasma Mass Spectrometry. Results showed that tested products were able to limit infestation and to produce high quality olives and oils. Aluminum, copper and silicon contents monitored in the fruits and oil did not show any significant risk for consumers.
