ABSTRACT

Studies on the bioefficacy of native isolates of Bacillus thuringiensis Berliner against rice leaf
folder Cnaphalocrocis medinalis (Guenee) were carried out in the Bt isolation and laboratory and
Glass House Complex of Department of Plant Breeding, Genetics and Biotechnology, PAU, Ludhiana.
Among 22 native isolates of Bt, three namely BtK4, BtC5 and BtJ showed more than 55 per cent
larval mortality of C. medinalis. Sublethel effects of promising isolates of Bt revealed that larval
and pupal duration were increased, whereas weights and survival of larvae and pupae were
decreased with higher concentrations of Bt. but these concentrations did not show any lethal effects
on the hatchability of eggs
