The field experiment was conducted at the farm of Institute of Agricultural Sciences, Banaras Hindu University during kharif 2004 to evaluate the bioefficacy of some newer insecticides against the major insect pests of short duration Pigeonpea, Cajanus cajan (L.) Millsp. The grain damage by pod fly, Melanagromyza obtusa Malloch was recorded lowest (13.2%) in the plots treated with Bifenthrin 10 EC @ 80 g a.i./ha and highest (19.0%) in the control plot. The pod damage by gram pod borer, Helicoverpa armigera (Hubner) on sprayed plots ranged from 9.2 per cent in flubendiamide 20 WG @ 50 g a.i./ha to 18.1 per cent in endosulfan 35 EC applied @ 700 g a.i./ha. However, all the treatments were found superior to control. Emamectin 5 WSG @ 11 g a.i./ha sprayed twice at 15 days interval gave highest grain yield to the tune of 810 kg/ha and it was closely followed by the treatment of Bifenthrin 10 EC @ 80 g a.i./ha which yielded 800 kg/ha. However, minimum (370 kg/ha) grain yield was obtained in control plot.
