Biology of fall armyworm, Spodoptera frugiperda (J.E.Smith) (Lepidoptera : Noctuidae) on sorghum

The findings of this study provide basic information about the biology of this recently invaded pest. Currently, the pest is spread to entire maize growing area of south India, including Maharashtra. Further spreading may occur as the pest is migratory. In the absence of maize, pest may shift to other hosts and survive and maintain the population in India throughout the year. Knowledge of the biology of fall armyworm on sorghum helps in the management of this insect.
