    • Abstract


      The oviposition response and development ofCallosohruchus chinensis Linn was studied on twenty promising varieties of mothbean. Though the beetle oviposited on all varieties, the preference for oviposition was not related to the suitability of seeds for the development. The development of grub was also not dependent on the amount of food consumed. There was significant difference among the varieties in the amount of food consumed per grub and the loss of 100 seed weight. On the basis of food consumed per grub and loss of 100 seed weight as a combined criterion, the varieties are grouped into least susceptible, moderately susceptible and highly susceptible varieties.
