(Lep.: Tortricidae). Use of pheromone trap is one of the suitable methods for monitoring and controlling of the pest. In this work, three main factors which affect the efficiency of traps including trap type, pheromone dose and installation height trap were studied. Four types of trap including cylindrical, rectangular, delta and wing trap were tested. Capture efficiency of the traps, were installed in the middle, and top heights of the trees were compared. Three doses of pheromone 0.5, 1, and 1.5 mgr per trap were also compared. Results showed that there were significant differences among four types of traps. Cylindrical, rectangular and delta traps caught more number of moths than wing trap (P0.05). However, a significant differences was observed among three doses (P M3 ER -
