%X two experiments were conducted in a greenhouse, with the objective of identifying sources of resistance in 15 corn cultivars to spodoptera frugiperda. the following cultivars were utilized cms-35 , cms-36, dina-70, cargill-525, pioneer-3210, pioneer-6875, br-201, br-451, ag-106, ag-510, cms-22, contimax-322, br-201, jatin£¿ c3 an£¿o, cargill-511 e br-106. when the plants had 8 to 10 leaves they were infested with 30 newly ecloded larvae per plant. damage evaluation was made 10 to 14 days after infestation, in both experiments, using a visual note scale from 0 to 9. there were no statistical differences among cultivars for the parameters evaluated damage, weight, length and survival larvae. nevertheless a significant linear correlation was found between weigth x larvae length (n = 0,7776, p = 0,01), demonstrating that these parameters can be utilized in the study of corn resistence to s. frugiperda.
