This study had the objective of surveying the apicultural potential in the municipality of Petrolina flora (9o9'S; 40o22'W), aiming at identifying the nectariferous or polliniferous species visited by Apis mellifera. The observations were carried out from January 2004 to May 2005, in areas of hyperxerophilous Caatinga native vegetation and of irrigated fruit crops of Embrapa Tropical Semi-Arid. Fifty one species were observed, belonging to 42 genera and 25 botanic families. The families Leguminosae, Anacardiaceae, Convolvulaceae, Rubiaceae and Sterculiaceae were the most visited species by Apis mellifera, including 47.08% of the total visited plants. Among the species visited by Apis mellifera, 41.17% are herbaceous, showing the importance of this stratum as an apicultural source. Regarding the flora resource used as food source by the bees, it was found that A. mellifera made several visits for exclusive nectar extraction to 72.55% of the plants considered nectariferous. Among the remaining plants, it was found that in 19.60% the bee collecte pollen, being these species considered polliniferous, and in 7.85% there was pollen and nectar withdrawal. Among the herbaceous species, Borreria verticillata (L.) G.Mey., Diodia teres Walter (Rubiaceae), Waltheria rotundifolia Schrank (Sterculiaceae), Merremia aegyptia (L.) Hallier, Jacquemontia confusa Meisn. (Convolvulaceae), Hypenia salzmanni (Benth.) Hanley (Lamiaceae) distinguished as nectariferous source during the raining season, while the arboreal species Schinopsis brasiliensis Engl. and Myracrodruon urundeuva Allemão. are considered apicultural source for the dry season.
