Trichogramma atopovirilia Oatman and Platner, T deion Pinto and Oatman, T exiguum Pinto and Platner, T fuentesi Torre and T. pretiosum Riley, were determined from 27 samples collected in the following crops: cotton plant, sugar cane, serrano chili, cabbage, sunflower, corn, orange, walnut, soybean and tomato, established in eight states in Northern Mexico. T. pretiosum was found in cotton, serrano chili, cabbage, sunflower, corn, orange, walnut, soybean and tomato.; I fuentesi in samples of corn and walnut; in corn samples to I deion and T. exiguum; and I atopovirilia in sugarcane. T pretiosum was found in 19 of the 27 samples checked, in contrast I atopovirilia and T. exiguum were determined in one sample each. The taxonomic determination of I deion and T. fuentesi in samples of corn are considered as new records for Mexico.
