RESUMEN
The pollen diet of Africanized honeybees Apis mellifera L. was studied during seven months (October 2006 to April 2007) in a natural forest fragment in the southern Pantanal, sub-region of Abobral, Mato Grosso do Sul. The analysis of the pollen diet was based on direct observations of the bees visiting flowers as well as through the use of a pollen trap installed in a wild colony in a tree hole in the same forest fragment. The total of 28 species in 15 botanical families were observed as potential sources of pollen for A. mellifera, with visits registered in 24 of these species in 13 botanical families. In the pollen trap we recorded 25 pollen types. This study is the first report to use this type of trap for pollen collection in the Neotropical region and aimed to identify the polliniferous bee plants of Brazilian pantanal.
