The study was conducted to know the effect of dual toxin Bt cotton on Spodoptera litura larvae at regional agricultural research station, Lam, Guntur, A.P. during 2014-2015. The data revealed that survival rate of 3rd instar larvae was higher and recorded only 30 - 35 per cent mortality, whereas the influence of BG II hybrids on grown up 4th and 5th instar larvae was very minimal no mortality was recorded and BG I and non Bt hybrids had shown no mortality. The mean weight of larva fed on BG II cotton leaves was found to be very low, whereas BG I hybrids shows marginal influence and non Bt versions did not affect the larval or pupal weight and weight gains were more or less similar.
