Abstract

Adult food supplements influenced oviposition period, post-oviposition period and fecundity significantly, while pre-oviposition period and longevity were not affected. Maximum eggs/female (1245.2) were laid when adults supplemented with the baker's yeast granules + 50% honey followed by baker's yeast granules + castor pollen + 50% honey (1069.2) and castor pollen + 50% honey (450) as compared to control, i.e. 50% honey (80). The oviposition ranged between 6.14 -27.11 eggs/day when fed on different adult food supplements. Productive age of female was observed up to 8, 9, 8 and 4 weeks when fed on baker's yeast granules + castor pollen + 50% honey, baker's yeast granules + 50% honey, castor pollen + 50% honey and only 50% honey, respectively.
