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.

The laboratory experiment was conducted at RARI, Durgapura during rabi 2017 to find out the toxicity of insecticides, bio-pesticides & plant product against H. armigera were reared on gram leaves and pods as well as on artificial diets. The nucleus culture of H. armigera was maintained in the laboratory under controlled conditions (26 _+2°C and 80 +- 5 percent RH). The 12 days old larvae of H. armigera use as a test insect by residue film method for bioassay.
