The feeding of lepidopteran pests, Amsacta albistriga W., Aproaerema modicella D. and Spilosoma obliqua W., caused feeding stress in the Arachis hypogaea L. plants. As a common defensive response, the plant exhibited variations in the primary and secondary metabolic contents. Groundnut plant antioxidative enzymes such as peroxidase, superoxide dismutase, polyphenol oxidase, catalase and phenyl ammonia lyase exhibited alterations to confer resistance against the pest. Phenolic compounds, namely coumaric acid, chlorogenic acid, resveratrol, epicatechin, ferulic acid and caffeic acid, showed active defensive role in groundnut plant against the pest feeding through their significant presence in Fourier transform infrared spectroscopy, high-performance liquid chromatography and gas chromatography studies. Changes in metal contents like iron, magnesium, zinc, potassium and calcium were also reported through atomic absorption studies, indicating their defensive role against the biotic stress caused on groundnut by the three lepidopteran pests. The present study can further assist in recognizing the importance of these specific phenolic acids and metals of groundnut in its pest management.
