Helicoverpa armigera (Hubner) is the major constraint for the production of chickpea as it feeds on the pods causing direct economic damage to the farmers. A single H. armigera larva feeds 30-40 pods in its life time. It is polyphagous and multivoltine pest which is difficult to control. Farmers generally rely on the insecticides but this pest was reported to show resistance to most of the insecticides used against it. Host plant resistance for managing this pest is best as it is compatible with other pest management practices.

A research work to study the richness of arthropod diversity under short duration pigeonpea intercropping systems was carried out at Agricultural Research Farm of Banaras Hindu University, Varanasi (UP). The faunal composition of insect pests associated with short duration pigeonpea intercropping systems in kharif 2004 and 2005 was of eight orders viz., Orthoptera, Homoptera, Thysanoptera, Lepidoptera, Diptera, Hymenoptera and Coleoptera. One bird pest of order Psittaciformes was also recorded.
