Effect of Bacillus thuringiensis (B.t.) formulations/strains on the growth and development of Helicoverpa armigera was studied in vitro. Of the formulations, Biobit was most toxic to the neonates, followed by Biolep, HD-1, HD-73 and Dipel. Toxicity of these formulations decreased considerably against 5-day old larvae. HD-1 showed highest toxicity to the 5-day old larvae, followed by Biobit and Biolep. Larval growth was considerably reduced in HD-1 and other formulations except for HD-73 where it was at par with control. B.t. affected last instar larval growth and development, pupation and also adult emergence.
