Investigations on evaluation of different bio pesticides against pearl millet ear head worm, Helicoverpa armigera in pearl millet crop were made at Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during Kharif 2015. Insecticides used in experiment were spinosad @ 0.014 per cent, indoxacarb @ 0.0079 per cent, Beauveria bassiana @2.5 kg/ha, Lecanicillium lecanii@ 2.0 kg/ha, HaNPV @ 500 LE/ha, azadirechtin @ 0.000375 per cent and Bacillus thuringiensis @1.5 kg/ha. Among the eight treatments, spinosad @ 0.014 per cent and indoxacarb @ 0.0079 per cent was found to be most effective in reducing the larval population of H. armigera. The treatments HaNPV @ 500 LE/ha, B. thuringiensis @1.5 kg/ha and azadirechtin @ 0.000375 per cent found moderately effective for the control of this pest. L. lecanii @ 2.0 kg/ha and B. bassiana @2.5 kg/ha proved to be least effective against pearl millet earhead worm. Spinosad @ 0.014 per cent recorded the highest grain yield of pearl millet (2685 kg/ha) and it was at par with indoxacarb @ 0.0079 per cent (2477 kg/ha). As far as economics of various insecticides are concerned, the treatments of HaNPV @ 500 LE/ha or spinosad @ 0.014 per cent or azadirechtin @ 0.000375 per cent were found as effective and economical as recommended synthetic insecticides and are recommended for eco-friendly management of H. armigera in pearl millet ecosystem.

Insecticides used in experiment were spinosad @ 0.014 per cent, indoxacarb @ 0.0079 per cent, Beauveria bassiana @2.5 kg/ha, Lecanicillium lecanii@ 2.0 kg/ha, HaNPV @ 500 LE/ha, azadirechtin @ 0.000375 per cent and Bacillus thuringiensis @1.5 kg/ha. Among the eight treatments, spinosad @ 0.014 per cent and indoxacarb @ 0.0079 per cent was found to be most effective in reducing the larval population of H. armigera. The treatments HaNPV @ 500 LE/ha, B. thuringiensis @1.5 kg/ha and azadirechtin @ 0.000375 per cent found moderately effective for the control of this pest. L. lecanii @ 2.0 kg/ha and B. bassiana @2.5 kg/ha proved to be least effective against pearl millet earhead worm. Spinosad @ 0.014 per cent recorded the highest grain yield of pearl millet (2685 kg/ha) and it was at par with indoxacarb @ 0.0079 per cent (2477 kg/ha). As far as economics of various insecticides are concerned, the treatments of HaNPV @ 500 LE/ha or spinosad @ 0.014 per cent or azadirechtin @ 0.000375 per cent were found as effective and economical as recommended synthetic insecticides and are recommended for eco-friendly management of H. armigera in pearl millet ecosystem.
