Studies on basic developmental characteristic of fall armyworm, Spodoptera frugiperda (J.E. Smith) on maize

During studies on the biology of the fall armyworm, Spodoptera frugiperda (J.E. Smith), on maize a gravid female was seen depositing eggs, with a fecundity of 1130 eggs. The incubation time, total larval duration, pre-pupal phase, and pupal period were observed to be 2-3, 15-18, 2-3, and 7-11 days, respectively. Male and female life cycles were found to be 32-38 and 34-42 days, respectively.
