Totally, one hundred and sixty-eight floral plants (59 families) at (Botanical Garden, Bioversity and NBAIR) UAS, GKVK Bengaluru, ninety-nine floral plants (42 families) at Ethno Botanical Garden (I-AIM), Bengaluru, ninety-eight floral plants (38 families) at BBMP park, Sampigehalli lake, Jakkur, seventy-six floral plants (35 families) at Purva- Venezia Apartment, Bengaluru and fifty-six floral plants (33 families) at Farmer’s field, Tatva Vaidika Grama, Bengaluru were visited by T. iridipennis. The floral plants include ornamental plants, weeds, tree species, medicinal plants, fruit crops and field crops. The maximum number of floral plants provided both nectar and pollen compared to only pollen or nectar. The maximum number of floral plants that were visited by T. iridipennis, were flowered from January-December in selected urban and peri-urban ecosystems of Bengaluru which facilitated the better growth and development of T. iridipennis colonies. Five hive designs (HD) viz., HD- 1 (5575 cm3), HD-2 (23x10x10 cm3), HD-3 (30x10x10 cm3), HD-4 (18x15x5 cm3 (Brood chamber) and 18x15x4 cm3 (Honey chamber) and HD-5 (27x12x10 cm3) were evaluated for the growth and development of T. iridipennis in selected urban and peri- urban ecosystems of Bengaluru. Volume of brood cells, pollen pots, honey pots, colony, number of brood cells, pollen pots, honey pots, hive occupancy and weight of T. iridipennis colonies was maximum in HD -3 (30x10x10 cm3) compared to rest of hive designs.EnglishThesis
