The field experiment were conducted at Research Cum Instructional Farm at IGKV, Raipur (C.G.) during kharif 2018, to know the seasonal incidence of fall army worm, Spodoptera frugiperda infesting maize crop. Fall army worm, Spodoptera frugiperda appeared during 37 th SMW i.e. 2 nd week of September with a mean population of 0.12 larva/plant. The peak population were observed in the fourth week of September with a mean population of 0.56 larva/plant. Thereafter, the population declined gradually and reached to a minimum level of 0.16 larva/plant during 4 th week of October (42 nd SMW). The correlation between fall army worm, Spodoptera frugiperda and abiotic parameters during kharif 2018 results indicated that the population demonstrated a significant positive correlation with maximum temperature (r=0.586).
