The use of several chemical pesticides, usually employed for Bactrocera oleae control, are recently forbidden or restricted by new European Community Regulation on chemical and their safe use. It determines the strong need to test new active substances in order to prevent the development of the above-mentioned phytophagous, the most noxious olive parasite, in relation to the improvement of olive oil quali-quantitative features. The present study has been performed in an olive area of southern Italy, located on Ionian sea coast (Mirto-Crosia, Calabria), characterised by bio-climatic conditions favourable for development of B. oleae which causes remarkable infestation percentages. For B. oleae control imidacloprid, an active substance belonging to a new class of nicotinoids, has been tested by spraying on the canopy in a young orchard made up by 20-year-old plants. A comparison among imidacloprid treated plot, control (untreated) plot and dimethoate (a traditional insecticide against B. oleae) treated plot, was performed. The efficacy of tested compounds in the different plots, has been evaluated by monitoring adult field populations by using yellow chromotropic traps and determining active and total infestation percentages by laboratory analysis of drupe samples collected every ten days. The results showed that imidacloprid is very effective against olive fly adults as indicated by the field adult population trend. Satisfactory results concerning the active and total infestation were obtained, especially in relation to the harvest time.
