NUTRITIONAL VALUE OF DIFFERENT POLLEN MIXTURES FOR NANNOTRIGONA (SCAPTOTRIGONAj POSTICA
P. R. TESTA, A. N. SILVA AND F. S. ZUCOLOTO
The nutritional value for Nannotrigona (5.) postica workers of mixtures of pollen from hives of N. (5.) postica and Apis mellifera was tested by comparing ovary and hypopharyngeal gland development in groups fed different proportions of pollen from the two sources. A mixture of 75% pollen from N. (5.) postica and 25% pollen from A. mellifera was a satisfactory substitute for 100% N. (5.) postica pollen.
