This study aimed to evaluate qualitatively and quantitatively the Hypsipyla grandella (Zeller) damage in fruits of mahogany in Brasilia, Brazil. For this, fruits were collected and the analysis of each fruit was carried out by assessing the following parameters: fruit weight, fruit length and height, number of holes in fruits characteristic of H. grandella attack, size of the holes, number of larvae and pupae of H. grandella, number of seeds damaged and presence of other insects within the fruit. As a result, 190 (95%) had holes made by the larvae, used primarily for their entry and for exit later as an adult. Most of the fruits showed only a single hole (81%), but up to 5 holes were found in a single fruit. A single caterpillar can feed on various seeds, causing major damage when they attack together. Seventy-two (36%) fruits had all the seeds damaged by H. grandella, especially those containing pupae. 183 larvae in different instars and 45 pupae were found. Only five caterpillars were found dead inside of fruit, representing 2.78% of the caterpillars.
