This paper deals with the occurrence and damage of Grapholita molesta (Lepidoptera: Tortricidae) in a commercial peach orchard with six cultivars of different fruit ripening cycles: precocious ('São Pedro '), medium ('Chimarrita ', 'Ouro ', 'Coral ' and 'Marli ') and late ('BR II '), in Araucaria, State of Paraná, Brazil. Five plants of each cultivar were selected for evaluating the damages in shoots and fruits. The damages were accumulated and evaluated in three phases: previous thinning, stone hardening and harvesting. The results were as follows: the cultivar "Ouro" was the most damaged one up to the harvesting phase, although 'Chimarrita' surpassed 'Ouro' when the damages observed in the post-harvesting phase were included. Among the six cultivars, 'Marli' was the one presenting the highest number of damaged fruits.
