The present study was conducted during kharif 2022 at the Agricultural Research Farm, Baba Raghav Das Post Graduate College, Deoria. The variety Vivek Maize hybrid 53 was sown with a spacing of 45x20 cm. The result revealed that the fall army worm Spodoptera frugiperda (J E Smith) larvae appeared in the field during 5th week of August (35th SMW)-1.67 larvae/ plant and reached peak during 3rd week of October (42nd SMW)- 4.16 larvae/ plant. The correlation studies revealed that the weather parameters viz. maximum and minimum temperature, maximum and minimum relative humidity and rainfall were negatively correlated with the incidence.
