Resumo: | Morphological studies of Meliponine worker ovaries in five species indicated a possible stimulatory effect of the queen on ovary development and on the production of trophic eggs in some of them. There are also indications that the queen inhibits the production of fertile eggs by the workers. This inhibition may involve a delay in the development of fertile eggs by the worker, until she is out of direct contact with the queen, or a lack of ovary development in the queen's presence, as seen in Leurotrigona muelleri. The evolutionary tendency toward inability to produce fertile eggs has its extreme representation in the pupal worker ovary reabsorption found in Frieseomelitta silvestri. On the other hand, the finding, in some species, of dwarf queens with the basic number of ovarioles (four) in the ovaries, along with normal, trophically determined queens with larger numbers of ovarioles in the ovaries demonstrate the influence of food on this character, as in Apis mellifera.
