Of the climatic conditions that can impair Trichogramma spp. parasitism capacity, the temperature is crit ical. Thus, the objective of this research was to evaluate the parasitism capacity of Trichogramma pretiosum on eggs of T. ni at 18, 21, 24, 27, 30, and 33ºC; 70±10% RH; and 12/12 hours photophase (L/D). Fres h eggs of the host moth were offered to T. pretiosum daily. The parasitism rate varied be tween 8 and 11.4 eggs/female at the te mperatures evaluated for the first 24 hours. The highest number of parasitized eggs per female occurred at 24ºC (53.0 parasitized eggs/female). The period of parasitism and the mean longevity of females were inversely related to the temperature. Temperature heavily influences the parasitism rate of T. pretiosum on eggs of T. ni , and the best overall performance of the parasitoid occurs from 24 to 27ºC. 2014 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303031660004 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
