Abstract

The research was conducted at olive orchard in Mokhtaria Research Station, Agricultural Research Center in Homs governorate during season 2018. Many attraction traps were used in management of Bactrocera oleae G. (Diptera: Tephritidae) named: pheromone Jackson, pheromone sticky yellow, food sticky yellow (di-ammonium phosphate 2%), food Sticky yellow (hydrolyzed protein2%), Mc Phail (di-ammonium phosphate 2%), Mc Phail (hydrolyzed protein2%), plastic bottles (di-ammonium phosphate 2%) and plastic bottles (hydrolyzed protein 2%). The results showed that Mc Phail traps (di-ammonium phosphate 2%) attracted the highest number of B. oleae in an average of 97.95 (fly/ trap/ week), then Mc Phail traps (hydrolyzed protein 2%) with an average of 48.59 (fly/ trap/ week), then plastic bottles traps (di-ammonium phosphate 2%) in an average of 20.59 (fly/ trap/ week), while the average of attraction of the other  traps ranged from 8.22 to 20.14 fly/ trap/ week), and the highest attraction of traps was at the beginning of September with an average of (Mc Phail traps di-ammonium phosphate 2%, hydrolyzed protein2%) (185.0, 110.33 fly/ trap/ week) respectively, while the  plastic bottles (di-ammonium phosphate 2%) averaged (45.67 fly/ trap/ week). The climatic factors averages (maximum and minimum temperatures and RH%) had a positive impact on B. oleae  where the simple correlation values were (0.46, 0.25, 0.23) respectively,  which led to a sudden numerical explosive of B. oleae. There were four generations per year, the third generation was the most dangerous. The results of statistical analysis appeared that there were  significant effects between Mc Phail traps (di-ammonium phosphate 2%, hydrolyzed protein2%) and other treatments, and also between plastic bottles traps (di-ammonium phosphate 2%) and pheromone Jackson at level 5%. It might be possible to use the traps Mc Phail and plastic bottles of di-ammonium phosphate 2% in reducing numerical density of B. oleae as an environmentally friendly techniques.
