A field experiment to study the population dynamics of (J. E. Smith) on maize was Spodoptera frugiperda carried out during 2019 at the Instructional Farm, Rajasthan College of Agriculture, Udaipur Kharif, (Rajasthan). The fall armyworm larvae began infesting the crop from the 29 SMW and their numerical th abundance peaked during the 33 SMW with a mean population of 26.50 larvae/10 plants; while, the rd incidence of its associated larval parasitoids started during the 31 SMW and the population reached to its st peak in the 33 SMW with a mean population of 3.75 larvae/10 plants. The population of fall armyworm and rd its parasitoids evinced a significant and positive correlation (r = 0.68), (r = 0.64) with total rainfall, respectively. During the study, total six hymenopteran larval parasitoids (3 species of Braconidae, 2 species of Ichneumonidae and 1 species of Bethylidae) were recorded
