Larval migration of late second instar tobacco caterpillar Spodoptera litura (Fab.), was observed in pure and mixed stands of nontransgenic and BG-II cotton, Gossypium spp. L., expressing an insecticidal protein Cry 1 Ac + Cry 2 Ab from a bacterium, Bacillus thuringiensis Berliner subspp. kurstaki. Three plots i.e., two mixed stands (Mallika and Bunny BG-II along with non Bt) and one pure stand(BG-II cotton) were evaluated. In case of mixed planting non Bt plants were infested with late second instar larvae at 60, 75 and 90 days after sowing of the crop. In pure BG-II cotton only selected BG-II plants were infested with late second instar larvae at 75 days after sowing of the crop. These data provide evidence of larval movement between plants in seed mixtures. Migration of S. litura larvae from non Bt to BG-II cotton hybrid in mixed stand and BG-II cotton to BG-II cotton within pure stand was observed at 60, 75 and 90 DAS. The larval migration was more in pure stand (BG-II cotton field) compared withmixed stand cotton. More number of larvae was observed on leaves followed by flowers, squares and bolls irrespective of pure and mixed cotton.
