Abstract Biological aspects of Trichogramma pretiosum Riley, 1879, reared on artificial host Ephestia kuehniella (Zeller, 1879), were studied in incubators at 25°C (± 1°C); 60% (± 10%) RH and 14h photophase with the aim of obtaining basic information for the biological control of Heliothis zea (Boddie, 1850) in corn crop. The average duration of the life cycle (egg‐adult) of T. pretiosum was similar when reared on natural and factitious host. Sexual ratio of the parasitoid was not affected by the natural or factitious host. The longevity of T. pretiosum was higher when reared on factitious host relating to natural host. The parasitism capacity of the two strains of T. pretiosum on E. kuehniella eggs was similar, with a high rate of parasitism in the first four days of the female's life.
