Six sugarcane cultivars were studied with the main purpose of comparing the percentage of infested stalks and the intensity of infestation by the borer - rot complex. The cultivars were planted in April of 1985 and the evaluations were made in May, July and September of 1986. The results indicated that there were no differences between the internal and external percentages of infested stalks. The internal and external intensities of infestation presented a positive and highly significant linear correlation. On the other hand, a significant correlation between the percentage of infested stalks and the intensity of infestation was not always found. The highest percentage of infested internodes was observed at the basal region of the stalk and the lowest at the apical one.
