Abstract - Biology of Xylocopa (Xylocopa) violacea (L., 1758) (Hymenoptera: Apidae): Sodium and Potassium content in pollen paste. The [K+], [N a+] and [ash] of Xylocopa violacea pollen paste is the aim of this contribute, comparing the data with literalure. [N a+]= 85 ppm = 0.0085 g/1OOg = 0.1163 mg/(1 PP) = 5.0578 [lMol/(1 PP). [K+] = 1765 ppm= 0.1765 g/lOOg = 2.4145 mg/(1 PP) =61.7556 [l Moli (l PP). [ash] = 1.45%. K+ is 12.17% of total ash; Na+ is 0.59% of total ash. These results confirm the hypothesis of cAMP-dihuretic-ormon in south-african. capitata.
