%X Pod borer (Helicoverpa armigera Hübner) is the single largest yield reducing factor in food legumes. Worldwide, pod borer causes an estimated loss of over $2 billion annually, despite over $1 billion value of insecticides used to control this devastating pest. In pigeonpea(Cajanuscajan(L.) Millsp.), an important food grain legume crop of the semi-arid tropics, Helicoverpa armigera causes maximum yield losses (25-70%) followed by pod fly, Melanagromyzaobtusa(10-50%), Marucavitrata(5-25%) and pod bug, Clavigrallagibbosa(10-30%). High levels of resistance to pod borer is not available in the cultivated genepool, which necessitates the exploitation of new anddiverse sources of variations.
