The influence that the queen of Paratrechina flavipes (Smith) (Hymenoptera: Formicidae) has upon workers was investigated in field and laboratory nests. There was no significant difference in sexual production, either of gynes or males, between field queenright and queenless nests of the ant. A replicated laboratory experiment revealed that workers lay fewer eggs and rear fewer sexual larvae in the presence of their mother queen, while this reduction is not observed in workers with influence of non‐mother queens. The results seem to support the queen's signal hypothesis by Keller & Nonacs (1993). The contradiction is explained by workers rearing sexuals in queenless satellite nests. There exists a probably complex regulation of the transfer of larvae between satellite and mother nests.
