The rearing of tobacco caterpillar, Spodoptera litura, in laboratory conditions is an ideal method for studying indirect development and holometabolous metamorphosis. The study envisages the developmental stages and life cycle of this agricultural pest moth under lab conditions, incorporating photographs and short videos alongside well-labeled schematic diagrams. Moreover, it elaborates on the laboratory rearing methods for these insects, encompassing the preparation of artificial diets in case the natural food source (castor leaves) is not available. These methods provide valuable insights into the growth and development of S. litura and help maintain a perennial healthy culture of this insect pest, which is a prerequisite for conducting any further experiments for its management and control in the agricultural setup.
