Present study was conducted to determine the effectiveness of Chrysoperla carnea in sustainable biological control programs. The experiment was conducted on six advanced genotypes of cotton cultivars viz. MNH-552, CIM-707, SLH-284, IRFH-901, CIM-496 and FH-115. Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) was used as a prey in the presence and absence of its natural predator, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae). Chrysoperla carnea depicted maximum reduction of whitefly population (57.35%) in 4dh week of August in MNH-552 followed by 2nd week of September in MNH-552 (57.14%), 3rd week of August in FH-115 (55.24%) and 4th week of August in FH-115 (54.09%). The minimum reduction of whitefly was observed in 2nd week of July in MNH-552 (23.56%), 2nd week of August in SLH-284 (28.43%) and 1st week of July in IRFH-901 (30.06%). So the use of C. carnea as bio-intensive IPM program reduced the insecticides and saved foreign exchange that spent on pesticide import.
