Abstract: The study on Seasonal Occurrence and Management of Thysanoplusia orechalecea on Soybean was carried out during Kharif season 2018-19 under field condition of the Entomology Section, College of Agriculture Nagpur. Seasonal incidence initiated during 29^th standard week (0.10 larva/mrl) and gradually attained maximum (1.00 larva/mrl) during 34^th standard week. Population was decreased from 36^th standard week onwards. The treatment of Emamectin benzoate 5 SG @ 0.02% was found superior amongst other treatments at each of 3, 7 and fenvalerate 20 EC @ 0.01% 14 days. As regards to soybean grain yield, the application of spinosad 45 SC @ 0.01% and fenvalerate 20 EC @ 0.01% were found to be most effective treatments recording higher yield of 13.46 q/ha, 12.82 q/ha, respectively.
