The parasitism capacity and development of Trichogramma atopovirilia and T. pretiosum were studied in order to select the most suitable species to control Spodoptera frugiperda. The experiments were conducted under laboratory conditions at 25+or-2 degrees C, 70+or-10% RH and 14L:10D photoperiod. Both T. atopovirilia and T. pretiosum showed good development and adaptation to S. frugiperda eggs even after being reared for several generations in eggs of Anagasta kuehniella However, T. atopovirilia females were more aggressive and showed higher specificity to the pest, with a higher parasitism capacity in eggs laid with different physical barriers and were more accepted by the natural host in comparison with A. kuehniella.
