Before launch, in the warehouse the biological indexes were determined of Trichogramma pintoi. The indexes were: a prolific female 31.9-a female egg, exclusion of the individuals 91.6%, female share 60.4%, static criterion of the quality 17.4. With the scope of determination of the moth’s parasitized eggs number by T. pintoi, in the warehouse from Chisinau, an artificial fond has been created to have a more precise evidence, by fixing 120 cards on the walls of the warehouse, window, machinery, with an amount of 12.000 eggs of Sitotroga cerealella preliminarily irradiated with gamma rays. In this warehouse T. pintoi has been launched in capsules, with a rate of 1:1 (host: parasite), meaning 12.000 moth eggs to 12.000 Trichogramma females. The cards have been later on gathered and analyzed in depth, this way being examined the number of parasitized and exhibited eggs. The results were 61.8 to 80.24% of parasitation.
