The olive fruit fly (Bactrocera oleae), the Mediterranean's the most important pest of olives has the great impact on olive oil quality. The larva of the olive fly feeds inside the fruit destroying the pulp and causes the degradation of triacylglycerols and consenquently the higher level of free fatty acid content and lower olive oil quality. To improve the quality of olive oil and to reduce negative environmental effects of pesticides applied in control of olive fruit fly, we had implemented monitoring network for controlling olive fruit fly in Slovene Istria area, which was carried out by the project SIGMA (INTERREG IIIA Italy-Slovenia). Olive fruit fly population and olive infestation monitoring has been conducted from 2005, and is based on pheromone traps located in thirty olive orchards. Based on monitoring results and meteorological data collected at 7 locations during the study period, were determined the most effective treatment time and improved the control of olive fruit flies. The results demonstrate that the olive fruit fly occurrence depends on geographical position of olive orchards and their microclimatic conditions.
