The bees are important animals in the pollination of them natural and cultivated plants, inclusive they have
established specific relations, appearing botanical important species in the sustentation of bees’s populations.
The intention of this investigation was to identify the bees (Hymenoptera: Apoidea) visitors of W. americana L.
(Sterculaceae) in agricultural area of the Rómulo Gallegos University, Guárico, Venezuela; in order to evaluate
the potential of this plant in the managing of the bees. An area was established by 10 plants of W. americana
and all the visitors bees of this plant were collected with insect-net. The samplings were done between the hours
6:00-14:00, during October-November months (2008) by eight samplings for month. There were collected 3009
individuals distributed in four families and 40 species of bees, correspondents to: Apidae 2785 individuals, 22
species; Halictidae 186 individuals, 11 species; Megachilidae 35 individuals, fi ve (5) species and Andrenidae
three (3) individuals and two (2) species. Apis mellifera
turned out to be the most frequent specie (52,21%). Ten
species of bees (25% of the richness) 2835 individuals add up. W. americana is a specie of great potential for the
maintenance of the richness and abundance of bees in the agricultural areas of the Rómulo Gallegos University.
