The goal of this work was to assess the suitability of two artificial diets for egg laying and development of Trichogramma atopovirilia Oatman & Platner, Trichogrammatoidea annulata De Santis, and Trichogramma bruni Nagaraja (all Hymenoptera: Trichogrammatidae). Additionally, the quality of wasps reared in vitro was compared with those reared in vivo. The ‘standard’ diet consisted of Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) pupal holotissues (65%), chicken egg yolk (18%), fetal bovine serum (8.5%), lactalbumin hydrolysate (8.5%), and anticontaminants (0.3%). The ‘modified’ diet differed from the standard one only in the D. saccharalis pupal holotissues, that were replaced with Heliothis virescens (Fabricius) (Lepidoptera: Noctuidae) ones. Females of the three trichogrammatid species laid eggs in artificial eggs containing any artificial medium, but the modified one received more eggs. Although the standard diet was accepted for oviposition by the three wasp species, no development occurred. On the modified diet, only T. atopovirilia was able to develop to adult emergence. Adult F1 were of a quality that was similar to insects reared in vivo.
