The ovicidal potential of seven different insecticides against the eggs of Spodoptera frugiperda was studied under laboratory and field conditions. Among the insecticides, profenophos and thiodicarb were found to have the highest ovicidal effect under laboratory as well as field conditions. But, their efficacy to reduce the larval population under field conditions was not promising and lowest yield of 35.81 and 38.63 q ha^-1, respectively, was recorded with profenophos and thiodicarb treated plots. Emamectin benzoate, chlorantraniliprole and spinetoram were found to be effective for management of FAW with moderate ovicidal action under field conditions with highest efficacy to control larval population, with yield of 57.58, 54.47 and 50.33 q ha^-1. Since, FAW exhibits overlapping generations, insecticides having ovicidal effect without reduction of larval population are not effective in controlling the pest.
