A total of twenty-eight native Bacillus thuringiensis strains were evaluated against neonate larvae of Helicoverpa armigera and found that three strains were effective with more than 80 % cumulative mortality, followed by seven strains with 51-75 and nine strains with more than 40% cumulative mortality at 7 days after treatment. Cumulative mortality of 83.3% was recorded in strain IBS1 which was statistically on par with each other and standard check Bt. kurstaki (HD-1) and also superior over other treatments. IBS5 and IBS14 also recorded higher cumulative mortality of neonate larvae of Helicoverpa armigera.
