Resumo: An experiment was conducted in the greenhouse to evaluate the effect of sorghum (Sorghum bicolor) cultivars and Spodoptera frugiperda (J.E.Smith) infestations, at different plant developmental stages, on sorghum yield. Second instar larvae of S. frugiperda were used to infest plants. Significant differences (P < 0.05) were found for the factors cultivar and stage of infestation for panicle (size and weight), grain (volume and weight) and 100 grain weight. No significant differences were observed for grain yield between damaged plant and the checks for the cvs. AG 3001 and CMSxs 375. However, the yields loss for the cv. BR 300 ranged from 11,6 to 21,7% for plants infested at 1st (15 days) and 4th stage (15 and 37 days), respectively.
