The biology of tobacco caterpillar, Spodoptera litura under laboratory condition

Abstract

The present investigation was carried out during the Rabi seasons of 2023-24 and 2024-25 a Laboratory of the Department of Entomology, College of Agriculture, Bikaner. The experimental site is situated approximately 9 km from Bikaner city along the Sri Ganganagar road. Spodoptera litura, a highly destructive polyphagous pest, completes its life cycle in approximately 34±3.50 days under controlled conditions. Its larval stages, marked by voracious feeding across five instars, cause extensive damage to castor and other crops. Detailed knowledge of its biology is vital for developing effective, sustainable pest management strategies.
