Among all the chemicals, the reduction of Aphis gossypii population was more with thiacloprid at 120 g a.i. ha-1 (86.34%) fol­lowed by flubendiamide+thiacloprid at 48+48 g a.i. ha-1 (74.36%) and thiamethoxam at 31.25 g a.i. ha-1 (61.09%). Thiacloprid (120 g a.i. ha-1), flubendiamide+thiacloprid at 48+48 g a.i. ha-1 and lambdacyhalothrin+thiamethoxam at 15.625+31.25 g a.i. ha-1 were highly effective in controlling Aphis craccivora population to 72.25, 71.35 and 62.61%, respectively.
