Abstract :

The tobacco cutworm Spodoptera litura Faicius (Lepidoptera: Noctuidae) is a serious polyphagous pest distributed throughout the tropical and subtropical world causing damage to more than 150 species of host plants. A suitable artificial diet is desirable for producing uniform insects for research purpose. In pursuit, a diet was formulated and assessed against a similar diet formulated for Helicoverpa armigera (Shobha et al., 2009) and castor leaves a natural diet for reå the larvae of Spodoptera litura in laboratory. The biological parameters based on mass reå of eleven continuous generations showed higher pupation (89.3±1.84) and survival (70.4±1.21) of larvae on new modified diet formulation, compared to that of Helicoverpa armigera diet (81.6±1.61 and 48.6±1.43) and castor leaves (78.1±1.18 and 45.3±0.06). The average number of eggs laid by insects reared on this diet was 3546.4±10.21, against 508.3±15.21 and 2618.2±17.31 those reared on castor leaves and Helicoverpa armigera diet respectively.
