An experiment was conducted to determine the host preference of pulse beetle, C. maculatus, based on fecundity, developmental period, adult emergence, sex ratio, percent damage and weight loss on seven locally purchased legumes namely gram, green mung, kidney bean, blackeye pea, lentil, split gram and pea. The highest fecundity of 51.2 eggs was recorded on pea and the lowest 26.6 eggs on lentil. However, the oviposition remained independent of growth and development. The shortest developmental period of 19.2 days each was recorded on green mung and split gram while the longest (23 days) was recorded on pea. Adult emergence, percent damage and percent weight loss were highest (28.6, 79.55% and 36.64%) on green mung and blackeye pea (27.6, 98.15% and 26.03%) and lowest on pea (5.2, 11.54% and 5.32%). The order of preference on the basis of weight loss was green mung greater than blackeye pea greater than split gram greater than gram greater than pea greater than kidney bean greater than lentil. The sex ratio on all legumes remained ca. 50:50. The pest neither developed nor inflicted any damage or loss to lentil and kidney bean.
