Rearing of brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guenee was studied in the laboratory on brinjal fruit, the usual host and potato in slice form or whole tuber as factitive host. Suitability of the host was determined on the basis of larval and pupal development and adult emergence of BSFB. Potato tuber was found as promising medium than brinjal fruit for rearing BSFB in the laboratory. Brinjal fruit and slice potato were identical as host for rearing BSFB. Whole potato was found to be better host for rearing than slice potato. An average of 40 larvae to be developed successfully in a single potato tuber of size 70-80g. Formation of pupae (49.76%) and emergence of adults (67.63%) of BSFB was significantly higher when whole potato was used as host. BSFB developed from the whole potato showed the highest fecundity (226.37).
