The corn stem borer, Sesamia cretica Lederer, 1857 (Lepidoptera, Noctuidae), is one of the main pest of maize, sorghum, sugarcane, and cereals in Iran, Mediterranean area, Middle East and Arabia to Pakistan, northern India and northern Africa. Effect of design of the trap, dosage of pheromone component in rubber capsule and trap height on the efficiency of Sesamia cretica pheromone traps were evaluated. The study was conducted in Runiz (Eestahban) of Fars province. A Randomized Complete Block Design used with four blocks and four replications in each block. To determine the best suitable trap design, three pheromone traps, Delta, Funnel trap and Wing shape, were tested. Three different heights, half, one and two meters from the ground were tested on order to determine the role of the trap height on the efficiency of traps. The doses of 0.5, 1 and 2 mg doses of the pheromones formulated in Iranian Research Institute of Plant Protection (IRIPP) compared with a foreign rubber capsule (1 mg). Data were analyzed by using of SAS statistical software and mean of treatments were grouped and compared by Duncan’s Multiple Range Test (DMRT). Delta and Funnel trap with highest moth catches were superior in comparison with wing shape trap design (P<0.01). Trap height to attract pests were not significant (P<0.01). The results of the test revealed that the 1 and 2 mg doses of the pheromones formulated in IRIPP and foreign rubber capsule (1 mg) were superior and had more catch but these doses were not significantly different (P<0.01).
