Conteúdo: | Biological aspects of Thichogramma pretiosum Riley, 1879, reared on factitious host Anagasta kuehniella (Zeller, 1879), were studied in incubators at 25 (+- 1.C); 60 (+- 10%) RH and 14 hour photophase with the aim of obtaining basic information for the biological control of Helicoverpa 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 A. kuehniella eggs was similar, with a high concentration of parasitism in the firstfour days of the female's life.
