Online published on 12 June, 2017. Abstract An insecticide efficacy trial was carried out during 2013–14 at four locations viz., Karnal, Ludhiana, Niphad and Pantnagar for evaluation of six new insecticides against foliar aphid complex in wheat. Aphid counts were made on five randomly selected plants, one day before spray and then after 1, 2, 7 and 15 days after spray. After one day of spraying, flubendamide 480 SC @20g a.i./ha resulted in the least number of aphids at Karnal (4.33/shoot) and Ludhiana (1.06/shoot). However, thiamethoxam 25WG @12.5g a.i./ha and chlorantranilipride 18.5 SC @20g a.i./ha were observed as the best at Niphad (1.50/shoot) and Pantnagar (17.53/shoot), respectively. The maximum yield of 45.42 q/h and 58.31 q/ha at Karnal and Ludhiana was obtained with acetamiprid 20SP @20 g a.i./ha, respectively, whereas at Niphad and Pantnager, highest yield was obtained with clothianidin 50 WDG @15g a.i./ha and imidacloprid 17.8 SL@20g a.i./ha.
