Comparative analysis of two sampling techniques for pollen gathered by Nannotrigona testaceicornis Lepeletier (Apidae, Meliponini)

K. S. Malagodi-Braga and Kleinert, A. M. P., Comparative analysis of two sampling techniques for pollen gathered by Nannotrigona testaceicornis Lepeletier (Apidae, Meliponini), vol. 8, pp. 596-606, 2009.

Pollen counts from samples taken from storage pots throughout one year (from October to September) were adjusted by Tasei’s volumetric correction coefficient for the determination of pollen sources exploited by two colonies of Nannotrigona testaceicornis in São Paulo, Brazil. The results obtained by this sampling technique for seven months (December to June) were compared with those from corbicula load samples taken within the same period. This species visited a large variety of plant species, but few of them were frequently used.
