Comparison of infestation rates of fall armyworm (Lepidoptera: Noctuidae) neonates for maize resistance screening.

ABSTRACT: An economically important global maize pest, fall armyworm (Spodoptera frugiperda (J.E. Smith)), feed on all above-ground portions of maize plants, primarily the whorl tissues. One of our research unit missions is to identify and develop maize germplasm with resistance to fall armyworm. One method to measure resistance in maize to fall armyworm is visual rating of leaf-feeding damage after infestation with neonates into the whorl. The objective of this study was to compare leaf-feeding damage ratings after infestation with different rates of fall armyworm neonates. The ultimate goal was to select the smallest infestation rate which could give the same damage effect on maize leaves as the larger infestation rates. Four susceptible and 7 resistant maize germplasm lines were planted in replic
