Field studies were made to assess the impact of artificial release of Chrysoperia carnea Stephens at different dosage levels (0.00,0.50,0.75,1.00 and 1.25 lakh/ha) against the pod borer, Helicoverpa arrnigera (Hubner) on pigeonpea. Realease of the biocontrol agent @1.25 lakhs/ha reduced the pod borer egg (30.08%) and larval (24.41%) population in pigeonpea. Pot and grain damage were reduced to the extent of 5 per cent with the release of C. carnea @ 1.0 and 1.25 lakh per ha over control. Grain yield was highest with these two dosage levels. A rupee investment using highly effective dosage level (1.25 lakh/ha) resulted in return of nearly 10 paise.
