This work was carried out to evaluate the damages caused by Grapholita molesta (Busck) in twigs and fruits of peach trees (Prunus persicae) in Caldas, MG, during the growing seasons of 1995/96 and 1996/97. Fruits and twigs from three branches of fifteen plants were examined every 15 days. A great variation in the percentage of twigs damage was obtained throughout each season, especially in the second year, when a peak was observed in the end of January. The averages of the porcentage of damage were estimated in 22,9% and 19,4% in 1995/96 and 1996/97, respectively. The total incidence in fruits was 28,1% during the first year and 21,6% during the second year with peaks well definided in the end of October and beginning of November of 1995/96.
