The frequent interruption of male courtship in highly crowded mass-rearing cages of
Ceratitis capitata (Wiedemann) was correlated with changes in both male courtship and female
acceptance criteria in a mass-reared Costa Rican strain, in accord with previous studies of other
strains. Abbreviation of courtship behavior by mass-reared males was associated with the loss of the
wild-type female tendency to reject males that performed shorter courtships. Consideration of
probable costs and benefits of female choice in mass-rearing cages suggests that inadvertant selection
in the cages probably favored the change in female criteria because females obtained sons with more
effective courtship behavior.
