Cycles of production occurred at intervals of 4 months, with male investment inversely proportional to the number of gynes produced. There was a tendency for colonies to produce only males or females as total sexual production increased. Sperm counts of known-aged males suggest that they mate twice, in contrast to European populations. Sex-ratio was heavily female-biased, contrary to predictions for polygynous ant species.235-238engMONOMORIUM-PHARAONISREPRODUCTIONSTRATEGYSEX RATIOMATINGArtigo10.1080/07924259.1993.9672320WOS:A1993MA13300023Acesso restrito72510535526375531050709055776428
