Summary

Workers and males of the stingless beeScaptotrigona postica emerge from morphologically similar cells. Normally only one bee is reared in each brood cell, but we found that some of the cells, interspersed throughout the brood comb, contained more than one egg. Because these additional eggs produced adult males, they were probably laid by nurse bees (workers) after the queen had oviposited in the cells concerned.

Although there is no morphological difference between male and worker cells a significant difference was found in the amount of food inside them. The cell where the male is reared shows less food than the worker cell, difference that is statistically significant at 1% level. This fact suggests that: the worker might recognise the cell before oviposition and that this recognition is based on the difference of food quantity.

Différences dans les quantités de nourriture contenues dans les cellules d'ouvrières et les cellules de mâles chez Scaptotrigona postica (Latr. 1807)

Resume

Les ouvrières et les mâles deScaptotrigona postica éclosent de cellules morphologiquement identiques. Habituellement, chaque cellule ne contient qu'une seule abeille. Cependant, nos observations montrent que quelques cellules, dispersées sur le rayon à couvain, contiennent plusieurs œufs. Etant donné que les œufs supplémentaires donnent des mâles, ils ont probablement été pondus par des ouvrières nourrices, après la ponte de la reine.

Bien qu'il n'y ait pas de différence morphologique entre cellules de mâles et cellules d'ouvrières, elles contiennent une quantité de nourriture significativement différente. Les mâles sont élevés dans des cellules qui contiennent moins de nourriture que celles où sont élevées les ouvrières: la différence est significative au niveau de 1 %.

Ceci conduit à penser que l'ouvrière pourrait reconnaître la cellule avant de pondre et que cette reconnaissance se ferait à partir de la quantité de nourriture contenue dans la cellule.
