Implementations of the tehnologies for production and applicaton of the entomophage Trichogramma evanescens during the 2006 were carried out under the laboratory conditions at the Institute for Plant Protection and Ecological Agriculture of the Academy of Sciens of Moldova and on the cabbage – 6ha - 200ha fields of Cooperative Farm „Agrosargal” in the village of Sarata Galbena, region of Hanchesti. Biological efficacy of Trichogramma evanescens with improved qualities on the cabbage – 6ha fields varied 70 to 88%, the degree of pest attack varied 4 to 7% in the variant with Trchogramma evanescens with common qualities varied 65 to 80%, the degree of pest attack varied 8 to 10% during the peniad of generations of development of noctuids complex. In control the degree of the noctuids complex attack was 55 to 6%. 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.
