Resumo: Cytophotometric observation of corpora allata from workers and queens of A. mellifera showed significant variations in DNA content from the 2nd to the 4th instar of both castes, but the differences between castes are present only in the 2nd instar. The corpora allata are characterized by the presence of diploid, as well as polyploid cells, distributed in classes that are well established since the earliest developmental stages. However the frequency of cell nuclei in the higher classes of ploidy increases with development. This occurrence is responsible for the increase of the average DNA content in older larvae. © 1990 International Bee Research Association.
