Carob moth (Ectomyelois ceratonia Zell Lepidoptera: pyralidae)is the most important reason of quantitative and qualitative reduction of pomegranate (Punica granatum) yield all over pomegranate cultivation regions of Iran like Isfahan province.Isfahan province with 7620.5hectare pomegranate orchards is in third place of pomegranate production (after Fars and Markazi provinces) in Iran (3), and following cultivars are the most important cultivars in Isfahan: Naderi, Ravandi, red aril soursweet, Shahvar sweet, Ameneh Khatooni and Zaagh shirin. Carob moth's damage was studied for three cultivars (red aril soursweet, white skin sweet and red skin sour) in five regions (Natanz, Koohpayeh, Shahreza, Rooran and Najafabad) during 2010 year.In order to determine tolerant cultivars and damage levels of this pest in Isfahan province, primary sampling was conducted to define required sampling number and 60 tree numbers distinguished as required sample. Then 60 trees of each cultivar were selected randomly from orchards of each region which had same aged trees of all three cultivars and larger than five hectares, infected and non- infected fruits were counted and recorded. According to results, regions and cultivars had highly significant (p
