Buzzing Wild Bee Visits Enhance Seed Set in Eggplant, Solanum melongena
Psyche: A Journal of Entomology, Volume 2017, Issue 1, 2017., 2017 Sixty percent of the angiosperms with poricidal anthers are buzz‐pollinated by bees (Hymenoptera: Apoidea: Apiformes). Plant taxa with Solanum‐type flowers have larger anthers and shorter filaments. Solanum melongena (Solanaceae) is more commonly and efficiently pollinated by buzz pollinators. The present study documented bees and their diurnal pattern

Large Carpenter Bees as Agricultural Pollinators
Psyche: A Journal of Entomology, Volume 2010, Issue 1, 2010., 2010 Large carpenter bees (genus Xylocopa) are wood‐nesting generalist pollinators of broad geographical distribution that exhibit varying levels of sociality. Their foraging is characterized by a wide range of food plants, long season of activity, tolerance of high temperatures, and activity under low illumination levels.
