Studies on the effect of bruchids (Callosobruchus chinensis L.) on biochemical and physico-chemical characters of fifty horse gram (Macrotyloma uniflorum) accessions was undertaken at Seed Research and Technology Center and National Bureau of Plant Genetic Resources (NBPGR), Regional Station, Hyderabad, Andhra Pradesh during the year 2011–12. Among the biochemical and physico-chemical characters, proteins, phenol content and seedcoatthickness of horse gramaccessions showed significant influence on oviposition, developmental period, adult emergence and seed infestation of C. chinensis. Less protein content, high phenols and thick seed coat of the accessions were detrimental to the growth and development of C. chinensis while high protein content, low phenols and thin seed coat of the test accessions favored the successful development of bruchids of pulse beetle.
