Abstract

Stingless bees (Apidae: Meliponinae) are essential pollinators of numerous native and cultivated plant species, especially in the tropics. Knowledge of the distance over which the bee travels in search of food is crucial for successful pollination. Less is known about foraging ranges of African stingless bee species. This study investigated the foraging range of an African stingless bee species, Hypotrigona gribodoi, using translocation experiments. The capture–mark–recapture method and release at various designated distances were used. This study showed >90% returning success of the bees when released up to 120 m from the hive. The distance at which bees attained 50% returns (typical distance) was 250 m, while the distance in which 90% of bees failed to return based on our regression function was 540 m. These results indicate that colonies of H. gribodoi placed in a field crop might provide good pollination within a radius of up to 250 m. The ability of foragers to collect pollen and nectar and the information about the distance they use for foraging is vital for managing and conserving stingless bees.
