Investigations were carried out at Department of Entomology, B. A. College Agriculture, Anand Agricultural University, Anand, Gujarat, India during 2011-12 on ten cowpea varieties viz., 'Anand-1', 'Anand-3', 'Anand-4', ‘Anand-5', 'RCV-7', 'RC-19', 'RC-101', 'Divya-405', 'Local Nirmali' and 'Pusa Phalguni' to see their reactions against Callosobruchus chinensis in storage condition. Among them 'Pusa Phalguni' had the lowest number of adult emergence (3.62) followed by 'Divya-405' (4.25) and 'RCV-7' (5.95). On the basis of per cent weight loss due to infestation of C. chinensis, ‘RCV-7' was found superior with lowest (1.73%) per cent weight loss after six months of cowpea storage followed by 'Divya-405' (1.76%) and 'Pusa Phalguni' (1.82%). Significantly lower germination loss was recorded in 'Pusa Phalguni' (14.03%), 'Anand-1' (14.61%) and 'Divya-405' (14.66%). Based on the above three parameters varieties ‘Anand-1', 'Anand-5', 'RCV-7', 'RC-101', 'Divya-405' and 'Pusa Phalguni' found highly resistant against Callosobruchus chinensis under storage
