(Lepidoptera: Sphingidae). This lepidopteran pest has natural enemies that can efficiently control its population, such as Trichogramma spp. (Hymenoptera: Trichogrammatidae). The objective of this research was to assess the flight capacity, parasi tism and emergence of Trichogramma pretiosum , T. marandobai and T. demoraesi and to select the most efficient species among them for biological control programs. The flight capacity of these species wa s assessed in test units co nsisting of a plastic PVC cylinder with a rigid, transparent plastic circle on the upper portion of the cylinder and an extruded polystyrene disk to close the bottom of the cylinder. A tube was placed in each test unit containing a card with 300 Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) eggs that had been parasitised by Trichogramma . These cards were later assessed to determine th e parasitism rate and adult emergence of these natural enemies. Trichogramma pretiosum presented the highest flight capacity (68 ± 5%), parasitism (74 ± 2%) and percentage of adults emerged (91 ± 3%) in the laboratory, making this species suitable for mass rearing and release in biological control programs. 2014 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303031660002 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
