Kermania pistaciella Amsel is an important pest of Iran pistachios which exists in the country most pistachio-rich regions. It was reported at Rafsanjan during 1344 for the first time and was identified and described by Amsel in 1964 as a new genus and species throughout the world. Pistachio twig borer moth do more damages wood mostly. This pest’s larvae penetrate the wood immediately after hatching and start damaging. In order to combat pistachio twig borer moth, the picnics are determined using pheromones trap that attract this pest’s male insects, and then, the time of chemical control of this pest was determinated. This research was conducted to determine the peak flight rate of pistachio twig borer moth as well as to determine the best pheromone brand concerning this insect’s absortion through three companies: Parsian, Zist Bani Paya and Raha Andish Kavan. Three hectares from pistachio gardens were selected with similar conditions and appropriate pollution of this pest; each hectare was considered as one block, and three pheromone traps were randomly installed in each block each by a separate brand. All the used traps were white. Daily traps counting was performed from the time of installation (03.01.1397) up to the time of non –absorption of butterfly (07.02.1397), and the data were analyzed using SPSS software. The flight peak was determined on 15.01.1397 on the basis of obtained data from the pheromone traps. The highest absorption was in the rate of 404.75 butterflies and average absorption was 158.34 butterflies during the project execution time by Zist Bani Paya pheromone. The lowest absorption was observed in Parsian pheromone. Accordingly, the most hunting of pistachio twig borer moth was related to: Zist Bani Paya, Raha Andish Kavan and Parsian pheromones, respectively.
