    Description / Table of Contents: Summary The life spans of femalesPolistes were influenced by the social environnement found at the emergence time, within the limits set by a probable larval predisposition. An early separation from the natal colony reduced the proportion of wasps able to overwinter and to found a nest the next spring. On the other hand, the removal of older larvae from the brood increased the proportion of long-lived wasps among the imago that undergo this situation. The functional consequences of these findings are discussed.
    Notes: Resume Cette étude montre que la durée de vie des femelles de poliste est influencée, dans les limites d'une probable prédisposition larvaire, par les conditions sociales rencontrées à l'émergence. La séparation précoce d'avec le guêpier d'origine diminue fortement la proportion des descendantes qui supportent l'hiver et fondent au printemps suivant. Par contre, la destruction, dans le couvain, des larves de grande taille provoque un accroissement de la proportion des descendantes à vie longue parmi les guêpes subissant cette situation à l'état imaginal. On discute la signification fonctionnelle de ces résultats.
