Life History Parameters of Fall Armyworm, Spodoptera frugiperda (J.E.Smith) on Maize in Haryana State

The biology of fall armyworm, Spodoptera frugiperda (JE Smith) was studied at laboratory, Department of Entomology, CCS Haryana Agricultural University, Hisar during, 2020-21 to know their life history and duration of different developmental stages.Insect culture was collected from the experimental area forage section, CCSHAU to get nucleus culture and to further study the biological parameters i.e. incubation period, per cent hatchability, larval period, pupal period, sex ratio, ovipositional periods etc.The eggs laid by S. frugiperda were ranged from 87-729 eggs with 82.0% hatchability, incubation period of 2.57 days, larval period of 16.32 days and pupal period of 7.22 days.Pre-ovipositional, ovipositional and post ovipositional period ranged from 2-3 (2.68±0.32),3-4 (3.02±0.16)and 3-4 days (3.82±0.65),respectively.Total life cycle of males and females was observed as 33.32 and 34.75 days, respectively.
