The experiment was carried out during rabi, 2010-11 at Student’s Farm, College of Agriculture, Rajendranagar, Hyderabad wherein the efficacy of nine insecticides were evaluated against aphids on gherkin. 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.
