The implementation of tehnologies for the production and applicaton of the entomophage Trichogramma evanes-cens Westw. during the year 2006 were carried out under the laboratory conditions at the Institute for Plant Protection and Ecological Agriculture of the Academy of Sciences of Moldova and on the tomatoes fields of the Cooperative Farm „Agrosargal” in the village of Sarata Galbena, region of Hanchesti. The biological efficacy of Trichogramma evanescens with improved qualities on the tomatoes fields varied from 70,0 to 83,0%, the degree of pest attack varied from 4 to 10% in the variant with Trchogramma evanescens with common qualities varied from 60 to 74%, the degree of pest attack varied from 8 to 16% during the peniad of generations of development of noctuids complex. In control the degree of the noctuids complex attack was from 55 to 80%. When compared the results of I and II variants and those of control by biological efficacy and of the degree of pest attack the difference is essencial.
