Mode of colony foundation influences the primary sex ratio in ants
Article Abstract:
Colony founding is an important period in the life cycle of ants, and new colonies may be initiated by independent foundation by queens without the help of workers. The method of colony founding may have far reaching effects on queen survival and colony development. The ant species Lasius niger and Linepithema humile were studied to compare the main sex ratio laid by queens in incipient and mature colonies. L. niger queens of incipient colonies were found to lay fewer haploid eggs than queens from mature colonies, although L. humile queens laid a similar amount of haploid eggs in both incipient and mature colonies.

Queen acceptance and nestmate recognition in monogyne and polygyne colonies of the ant Formica truncorum
Article Abstract:
Queen acceptance and nestmate recognition of Monogyne and polygyne colonies of the ant Formica truncorum were analyzed. Young queens introduced into the experimental colonies varies in female origin, wing status, and mating status. Monogyne colonies have high degree of female origin (nestmate versus non-nestmate) discrimination and destroyed mated females than virgin ones. Polygyne colonies are characterized by low degree of female rejection and low levels of discrimination between nestmates and non-nestmates.

Primary and secondary sex ratios in monogyne colonies of the fire ant
Article Abstract:
A study of the monogyne form of the fire ant, Solenopsis invicta, revealed that colony workers in the species played a prominent role in altering sex ratios by discarding male broods from colonies. This male offspring elimination scenario is greatly influenced by the nature of sex ratio of the primary brood produced by the queen.
