Resumo: Competition between one, two, three and four T. cordubensis females is evaluated in the present paper, regarding parasitism and emergence rate at 20°C, using Ephestia kuehniella Zeller (Lep., Pyralidae) eggs as host. As the number of females increased, a decrease in the female average parasitism was demonstrated by a negative linear regression. However, the parasitism difference was only found to be significant (p<O.05) between me population with only one female per egg card (±200 host eggs) and the populations with three and four females per egg card. On the contrary, emergence rate was not affected by the number of females per egg card. No cases of superparasitism occurred.
