Other claims from this paper (19)
- Observation Coffee flowers were visited by 24–36 bee species across blooming seasons.
- Observation Hypotrigona gribodoi was the most frequent flower visitor, with over 60% of 5941 bee visits.
- Observation Foraging rate and pollination speed, and pollination efficiency, varied among bee species.
- Association Solitary bees foraged on more flowers than social bees and visited more coffee trees and fields.
- Association Solitary bees spent less time per flower visited than social bees.
- Association Social bees deposited more pollen on flowers than solitary bees.
- Observation Fruit abortion due to self-pollination was not significant in this study.
- Association Pollination efficiency varied more significantly with sociality than with other bee functional traits.
- Association Pollination efficiency was not significantly influenced by tongue length and bee body size.
- Observation Hand-cross pollination gave a fruit set of 87%.
- Observation Controlled pollination gave a fruit set of 0.9%.
- Observation Single-flower visits by social and solitary bees gave a fruit set of 89.7% for social bees.
- Observation Single-flower visits by social and solitary bees gave a fruit set of 68.14% for solitary bees.
- Observation Meliponula ferruginea was the most efficient bee species, with 98.3% pollination efficiency.
- Observation Meliponula nebulata followed the most efficient bee species, with 97.1% pollination efficiency.
- Mechanism Morphological and anatomical characteristics of bee pollen storage may explain the differences in foraging behaviour and pollination efficiency of social and solitary bees.
- Association Pollination efficiency was influenced by land-use intensity, field management systems and habitat types in the surroundings of coffee fields.
- Association Pollination efficiency was not influenced by coffee field size, coffee genotypes or mass blooming wild vegetation.
- Recommendation Farmers should adopt pollinator-friendly conservation and farming practices, such as keeping 25%–30% of the farm uncultivated as pollinator reservoirs.
