In this paper we report on a study that tested the hypothesis that two Costa Rican Pegoscapus fig wasps (1) are not able to assess the number of foundresses per syconium and (2) define brood sex ratio by laying a constant number of male eggs (constant male hypothesis), independently of clutch size and superparasitism.

Ocencyrtus johnsonii is both gregarious and engages in superparasitism (Sjaarda 1989, Amarasekare 1998).
To test the hypothesis that this variation in body size generated by resource competition (caused by maternal superparasitism) persists into the next generation, after resource competition has been relaxed, we reared experimental lines at low (one egg per seed) or high density ([approximately equal to] 20-25 eggs per seed) for one generation, producing substantial variation in body size among lines.
It may indicate that there is no competition among individuals of this natural enemy within a single host colony or it avoids superparasitism (Silva-Filho et al., 2007).

These markings avoid self-superparasitism and sometimes the con-specific superparasitism (Alphen and Visser, 1990) and generally consist in pheromones secreted by the Dufour's gland (Rosi et al., 2001).
