Sažetak
Olivees beside vine grapes are the most important long term agricultural culture in Istra, Croatia. In 2006. it was estimated that Istra had 750.000 olive trees, a share of 18, 78% of total number in Croatia. The olive tree fly Bactrocera oleae Gmel. is one of the most important pest on olive's in general. Depending from year to year, it makes minor or larger damages on olives. The damaged olives for table use (fresh olive's) are not suitable for consummation, while in olive's for oil production, the olives contained with olive's larvae are lower in quality and affect the oil quality. In 2006. we researched the damage on olives from olive tree fly on 100 olives randomly picked. Olives were taken in mature state of technological ripeness, from 26th October till 10 th November on six localities (Rovinj, Vodnjan, Kaštelir, Poreč, and two locations near Livade). We examined ten cultivars (Rosigniola, Buža, Ascolana, Leccino, Carbonazza, Pendolino, Frantoio, Bjelica, Črnica and Picholine). We used two types of protection against olive oil fly, with and without chemicals. On untreated olives the most damage was spotted on variety Buža from Rovinj, while the least damage was on pendolino from Kaštelir and Črnica from Livade (with 1% of damaged olives). On treated olives the highest percentage of damage had cultivar Leccino from Poreč (21% damaged olives) while Pendolino from Poreč and Leccino from Livade had only 1% of damage.
