An experiment was conducted to observe the seasonal abundance of S. frugiperda were recorded weekly for the both years from July to October (2019-2021) wherein, the data larval population and plant damage were recorded and then subjected to statistical analysis. Seasonal abundance studies revealed that the larval population and plant damage due to S. frugiperda was started after 3^rd week of sowing. It was increased gradually and reached at its peak in 39^th SMW. Thereafter, larval population and plant damage started decline and recorded minimum in 44th SMW. The correlation studies revealed that the damage by S. frugiperda on maize showed significant maximum temperature, minimum temperature, morning relative humidity, evening relative humidity, were found positively correlated; remaining three factors viz. rainfall and sunshine hour, were found negatively correlated.
