Abstract The leaves, squares and bolls of the wild species had significantly higher trypsin inhibitor activity and polyphenol contents than the cultivated susceptible species of cotton. The contents of structural barriers such as ADF, NDF, cellulose, hemicellulose and lignin were much higher in the wild species than the cultivated ones. The wild species, however, had lower soluble protein contents in the plant parts viz., leaves, squares and bolls. The levels of PPO and POD were found to be higher in the various plant parts of wild species than the cultivated species. The trypsin inhibitor activity, polyphenols, structural barriers, POD, PPO were decreased in leaves, squares and bolls of varieties of cultivated species after infestation of bollworm complex.
