A field experiment on effect of intercropping on the incidence of gram pod borer, Helicoverpa armigera (Hubner) in chickpea was carried out during rabi season at experimental farm, Rajasthan College of Agriculture, Udaipur (Rajasthan). The four treatments of intercrop with gram viz. barley, wheat, mustard and linseed and one sole crop of gram were evaluated. The results revealed that overall mean per cent pod damage (17.99%) in gram sole crop was significantly higher than all intercropping system. The mean population of the pest in gram intercropped with linseed (4.43) and mustard (4.64) were at par and both these intercropping system carried significantly lower mean pest population when compared with gram sole crop (5.25) and gram + wheat (5.20) and gram + barley (5.23) intercropping system.
