dc.description.abstractFor this study, three species of Trichogramma were submitted to competition in such a way that each competed with only one of the two other species simultaneously. The species were T. embryophagum Hartig, T. maidis Pintureau & Voegelé and T. buesi Voegelé. The host eggs Ephestia kuehniella (Lep., Pyralidae) were first parasitized by one of the species and when the first occupant was in a prenymphal instar (free living embryo, L1, L2 and L3), adults of the second species were allowed to parasitize the eggs containing the living instar of the first species. Unider these conditions, T. embryophagum eliminated the two other species, T. maidis just eliminated T. buesi but only in two situations (L2, and L3) and T. buesi was inactive in all situations. When host eggs are available in sufficient number, all three Trichogramma species show a high intra and interspecific discrimination for host eggs recently parasitized.por
