In the present study, the bio-efficacy of different bio agents against sucking insect pest Whitefly, Bemisia tabaci Gennadius, was evaluated. Total three sprays of each bio agent were done to protect but cotton variety RCH-134 But (BG-II) from the infestation of sucking pest. In the result, it was found that maximum reduction in whitefly population was recorded in the treatment of Neem oil + liquid soap (61.53%) which was at par with the treatment of of NSKE 5% (56.90%) and Pest guard 5% (54.84%). These three treatments were superior to rest of the treatments. The treatment of Verticillium lecanii (38.28%) formed the next best treatment to reduce whitefly population, followed by Fusarium SP (37.09%), Beauveria bassiana (36.02%) and Buprofenzin I.G.R (31.76%).
