Abstract: The studies on “Population dynamics and management of fall armyworm, Spodoptera frugiperda (J.E. Smith) on rabi maize” was carried out under field conditions during Rabi 2020-21 at Agricultural Research Farm, Tirhut College of Agriculture, Dholi, Muzaffarpur District, Bihar, which is a sub-campus of Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar. The research outcome revealed that the lowest mean larval population (0.40 larvae/plant), damage severity (1.67/ plant) with the maximum grain yield (7.59 t/ha) and highest benefit cost ratio (4.60:1) was recorded in plot treated with Chlorantraniliprole 18.5 SC @ 0.4 ml/l, followed by Emamectin benzoate 5SG @ 0.15 g/l, Lambda-cyhalothrin 9.5% + Thiamethoxam 12.6% ZC @ 0.25 ml/l, Lambda-cyhalothrin 5EC @ 1 ml/l were found effective insecticides than Azadirachtin 0.15% EC (1500 ppm) @ 5 ml/l, and carbofuran 3G @ 0.50 g/plant, Beauveria bassiana 2.5 WP @ 2 g/l were found least effective insecticides among all other treatments.
