Sažetak
Olive moth (Prays oleae Bern.) is a periodical pest of olive tree (Olea europaea). It is one of the most important economic olive pests which in some years can cause up to 80% of yield loss. The aim of this survey was to investigate the efficacy of applying biological plant protection measures in order to reduce pesticide residue contained in olive fruit. The experiment was set up in 2014 in Vrsar, Croatia. An olive grove was planted with the variety 'Istarska bjelica' cv. and there were also two organic treatments set up, one using azadirachtin and the other using B. thurigiensis var. kurstaki pesticides. Flight of olive moth, development stages of anthophagus and carpophagus generations and damage have been monitored weekly. Flight of olive moth has been monitored using pheromone trap. The damage has also been monitored by collecting fallen fruits. After the first capture of adults on pheromone trap, we started looking into the developing stages and the damage of olive moth. The peak in adults capture on the pheromone trap of anthophagus and carpophagus generations and the development of eggs in each generation determined the treatment time. Comparison between each treatment has been carried out. The outcome of comparision was the following: the average number of captured olive moths, developing stages of olive moth and damage varied between treatments. Azadirachtin and B. thurigiensis var. kurstaki showed good effectiveness in suppression of anthophagus generation, while azadirachtin treatment showed better effectiveness in the decrease of captured adults and damage of carpophagus generation than B. thurigiensis var. kurstaki.
