This work was carried out to study the effects of adult feeding and mating on the biological potential and parasitism of Trichogramma pretiosum and T. acacioi (Hymenoptera: Trichogrammatidae) to improve their use in biological control programs. Both species presented higher parasitism and longevity whenever adults were fed. Fed and unmated T. pretiosum females led to low parasitism whereas T. acacioi females did not present parasitism whatsoever. Egg viability of T. pretiosum was similar for fed and mated individuals, but T acacioi showed lower values for this parameter when unfed and without mating. Unmated females produced only males while mated ones had more than 60% female descendents for both Trichogramma species. Therefore, mated and fed female...
