Bacillus thuringiensis var. kurstaki was as effective as monocrotophos (0.05%) in causing feeding cessation and mortality of Achaea janata (Linnaeus) on castor. However, it was ineffective against Spodoptera litura (Fabricius) larvae. Neem seed kernel extract (2%) resulted in ovipositional deterrence to S. litura.
