The present study evaluated the effects of varieties of green gram (Vigna radiata) and black gram (Vigna mungo) on the life stages of Spodoptera litura (F.). The observations on the feeding index, approximate digestibility (%), pupal weight, growth index and survival index of S. litura were made. The results revealed that the varieties Pusa 9531 of green gram and Sekhar of black gram were the most suitable for the development of S. litura, with maximum gained pupal weight of 321.25 mg and 333.00 mg, respectively. The least suitable varieties were the HUME 668 (251.00mg) of green gram and TU-94-2 (312.00 mg) of black gram based on gained pupal weight.
