Abstract

This study explores the impact of nest installation on Megachile bee populations, which are potential pollinators of mung bean crops in Uttarakhand, India. Field investigations over two seasons reveal that six Megachile species visit mung bean blooms regularly for their provisioning. Assessments performed pre- and post-nest installation show slight changes in Megachile abundance and species-specific responses to environmental factors. Post-nest installation M. lanata showed the highest abundance (5.13±0.77 bees/m2/5min) followed by M. umbripennis (4.76±1.05 bees/m2/5min), although nest occupancy rates were low. Correlation analyses of weather parameters show preferences for specific climatic conditions with temperature having a considerable influence. These findings highlight the intricate relationship between Megachile bees and environmental factors, underlining the need for specific pollinator management approaches. Further research into Megachile nesting behaviours is essential to enhancing crop pollination and ensuring sustainable agricultural practices.
