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 Jatinã C 3 Anão,. 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
