Sažetak
Bactrocera oleae is the most importanat olive pest in Montenegro. The infestation is located only on the fruit and results in significant damage and for this reason, induces the neccessity for its control. Various control methods and applications of chemical substances are directed towards suppression of adults and have preventive character, therefore monitoring of abundance and flight dynamics is of high importance. Trials were set in olive plantation of Centre for subtropical cultures in Bar, on native variety Žutica, in three years period (the year of 2005, 2006 and 2007). Flight dynamics was monitored by chromotropic and pheromone traps of Dacotrap type,
during the period from July to the end of October in all years of monitoring. Traps were monitored once a week and the flight dynamics of fly is showen through the average abundance of females and males on chromotropic and pheromone traps. In the region of Bar, which is the biggest olive area in Montenegro seaside, olive fly
developes several generations during one year. Generations interleave with each other and therefore the fly is present in plantations, with different appearance intensity, from begining of July untill the middle of December, and in some years the flight lasts even
longer, so the presence of adults is also detected in January. The maximum abundance, reffering to the most intensive flight is during September and October. Chromotropic traps hold out a more precise evaluation of population abundance present in the plantation, while pheromone traps are very important in infestation forecast and
appropriate treatment timing determination.
