Table 1 Taxonomic list of Hymenoptera visitor species to the flowers of cotton (Gossypium hirsutum, Malvaceae) and sesame (Sesamum indicum, Pedaliaceae), their number (n) of visits and their ability to initiate fruit set. Crosses indicate the initiation of fruit set, dashes no successful pollination. Flower visitors were recorded on 300 flowers per crop species, at three sites in the south of Burkina Faso, West-Africa during the flowering season in summer 2015. Scoliidae are scoliid wasps; Apidae are long-tongued bees including honeybees, small and large carpenter bees and stingless bees; Halictidae are sweat bees and Megachilidae mason bees.

From: Bee pollination increases yield quantity and quality of cash crops in Burkina Faso, West Africa
