Prosopis alba (“algarrobo blanco”) |
To find out the plants providers of
pollen for bee feeding, pollen analysis is a very useful method. In the present
research, pollen from nest provisions and scopal loads from museum specimens
was studied by light microscope. Despite the great diversity of floral
resources close to active nest aggregations in the Chaco region, the only
host-plant recorded in all nest pollen samples was Prosopis (known as “algarrobo”, which belongs to the same genus as the
“mesquite”). Another Prosopis species
was identified from museum specimens from Monte region.
