Stem borer moth, Sesamia cretica Lederer causes major damage on sugarcane. Sex Pheromone of S. cretica was synthesized in the chemical laboratory of Iranian Research Institute of Plant Protection. Efficacy of synthesized pheromone with 3 types imported pheromone of S. cretica from Russell, Econex & Silvanderson companies were tested at the fields of Sugar cane Agro-Industrial Company of Ahvaz during 2014. Also attractiveness of synthesized pheromone was investigated with funnel and delta traps.The results showed significant differences among treatments (p<0.01). Synthetic pheromone with doses of 0.5, 1 and 2 mg had more attractant (5±0.91, 2.75±0.45 and 3.75±0.85 mean±SE,respectively) in comparison with imported pheromones that had no moth capture. Analysis of imported pheromones by mass spectroscopy devices indicated these pheromone contain only two molecules include (Z)-9-tetradecen-1-ol and (Z)-9-tetradecen-1-ylacetate. None of imported pheromone have third molecule (Z)-11-hexadecen-1-ol and for this reason they had no attractantion for S. cretica in the field experiments. Funnel traps with doses of 1 and 2 mg had most trapping (12.25±2.68 and 11.25±2.80, respectively). Delta trap treatments with doses of 1and 2 mg had less capture (0.00 ±0.00 and 0.25±0.25).Therefore we can conclude that proper formulation for S. cretica sex pheromone is that of with three molecules and funnel trap is the most suitable shape for trapping S. cretica.
