Abstract
Among wild bees, Xylocopa bees are recognized as potential pollinators. They live throughout the world wherever woody plants occur, especially in forested regions. Since these bees occur year-long and are also multivoltine, they need to track the floral resources and shift to different species that satisfy their nutritional requirements. When there are many plants in flowering at the same time, the bees will look for those that offer most, qualitatively and quantitatively, or that agrees to their senses. Based on floral forms and richness of floral rewards, these bees use different foraging behaviors for efficient harvest of the rewards. The carpenter-bee flowers show certain characteristic features in morphology and floral rewards. The 12 plant species observed in the field for foraging activity of Xylocopa pubescens and X. latipes included Solanum carolinense, S. surattense Cassia alata, C. siamea, C. occidentalis, C. fistula, Peltophorum pterocarpum, Moringa oleifera, Crotalaria laburnifolia, C. verrucosa, Pongamia pinnata and Tecoma stans. Almost all species were medium-sized, non-tubular, zygomorphic and odourless. The floral reward was either pollen, or nectar or both. The nectar volume ranged between 1μl to 17μl, and the percent sugar concentration 20% to 60%. Arginine and phenylalanine were the common essential amino acids in all nectars, and in addition to these, histidine, leucine and iso-leucine were common in the pollen of all plants. Protein content ranged from 21% to 55% of pollen dry weight
