VIANA, BLANDINA F.; SILVA, FABIANA O.  e  KLEINERT, ASTRID M.P.. Solitary bees (Hymenoptera: Apoidea) in tropical sand dune: diversity and phyenology. Neotrop. Entomol. [online]. 2001, vol.30, n.2, pp.245-251. ISSN 1678-8052.  https://doi.org/10.1590/S1519-566X2001000200006.

The community structure of cavities-nesting solitary bees species was systematically investigated over two years, from May/97 to April/99, in a fragment of tropical sand dune, Salvador, Bahia (12º56'S; 38º21'W), Northeast of Brazil. Trap nests were placed randomly in the area, in blocks with 16 nests, with variable diameter at a height of 1.5 m. Traps were inspected each 15 days. Seven bee species established 62 nests. Two species were predominant in the area, Centris (Hemisiella) tarsata Smith (58% of the total of established nests) followed by Euplusia musitans Fabricius (31%). In general, bees' abundance showed seasonal fluctuations. The total frequencies of nesting varied between the two years of sampling. The two predominant species presented different seasonal patterns. There were always trap nests available in the field for the bees. Just 14% of the available nests were occupied.
