In light of the morphological and functional variation among sexes and castes, a comparative study has been made on Scaptotrigona postica.At the beginning of metamorphosis the corpora allata of the queen were larger than those of the worker and male; this confirms the existence of a real dichotomy in the female caste. The corpora allata of the queen showed three cycles of activity, but those of the worker and male only one. © 1980 International Bee Research Association.219-223engArtigo10.1080/00218839.1980.111000282-s2.0-84935787166
