tomatoleafminer moth Tuta absoluta(Meyrick) is one of the most destructive pests of tomato in many parts of the world including Iran. tomatoeleafminer to all stages of plant growth and invasion of host to the extent of 50-100% to create damage. Aerial plant organs of tomato in each stage of the growth of this pest could be attacked. Leaf and stem of larvae, most prefer the tomatoes and the whole of the damage, missing leaves, stems and dysmorphic abnormalities to the existence of direct damages, as well as larvae of fruit to create a hole for the tunnel, and along with that in this case. According to the quick-release this pest in most areas, the cultivation of tomato in Iran and the potential damages over it, creating the necessity of the implementation of the research was more than before. In order to study the types and amount of damages caused by the influx of pest moth tomato leafminer and evaluation of sensitivity and resistance of different tomato varieties, as well as the identification of sensitive and resistant genotypes compared to tomato leafminer for a farm in 2014-2015 on a research farm of College of agriculture, Persian Gulf University of the busher in the form of randomized complete block design with three replications was run.The genotype reviewed include: ES6515, Eden, komodoro, Qointini, Petoperayd5, Firinze, poolad, Zaman,Berlina,Golshan616 , SandikanF1, ES9090F1, Samar625,Sadeen21,Sadeen95, Gs12, Karun, Raha, Matin, golsar and Sanseed.Identification of sensitive and resistant towards cultivars of tomato with tomato leafminer the study and assessment of the damage to the traits of leaves and leaflets, damages to the damages to the plant on 3 times 20, 40 and 60 days after the onslaught of the RAS, as well as the calculation of the overall index logged losses to plant tomatoes.The results of the comparison of mean damages to different parts of the plant on 3 times 20, 40 and 60 days after the pest infestation, showed that the genotype, Raha, Quin
