Pigeonpea, Cajanus cajan L. is a common crop, frequently found throughout Brazil, mainly in small rural properties. This research was aimed at geting information on the diversity of visiting bees to flowers of pigeonpea, generating information on the structure of the bee community and the importance of this Leguminosae as source of food resources. Collections had been made weekly, between May and October 2005 in the Experimental area of the Center of Agrarian Sciences and Environmental of the UFBA, located in the Cruz das Almas, Bahia, in the interval between 6:00 AM and 06:00 PM. A total of 4.676 individuals was collected visiting the pigeonpea flowers. The Apidae family was represented by 99.25% of individuals and 76.19% of total species. The genera Xylocopa and Trigona were the ones that showed greater richness, with four and three species, respectively. Trigona spinipes was the most abundant species, with relative frequency of 83.1%, followed by Nannotrigona testaceicornis (5.1%).
