Two biocontrol based IPM modules, along with Punjab Agricultural University (PAU) spray schedules were evaluated for the management of cotton bollworms. IPM module II (3 sprays each for sucking pests and cotton bollworm + 8 releases of Trichogramma chilonis @ 1,50,000/ha/week + one release of Chrysoperla carnea @ 10,000/ha) was on par with PAU spray schedule in reducing the bollworm damage and increasing the yield. When T. chilonis (Bathinda strain) was integrated with insecticides it reduced the damage of bollworm by 70.3 percent and gave higher yield by 44.5 percent over insecticides alone.
