Technologies implementation for the production and applicaton of the entomophagous Trichogramma evanescens Westw. during 2006-2007was carried out under the laboratory conditions with in the Institute for Plants Protection and Ecological Agriculture of the Academy of Sciences of Moldova and in the tomatoes fields of the Cooperative Farm „Agrosargal” in the village Sarata Galbena, Hanchesti region and in the village Gura Bicului,AneniiNoi region. Biological efficiency of Trichogramma evanescens showed improved qualities of tomatoes – 26 ha fields varied from 83,0 to 84,8%, the degree of pest attack varied from 6 to 10% in the variant with Trchogramma evanescens, with common qualities varied from 74,0 to 75,8%, the degree of pest attack varied from 9 to 16% during the peniad of generations of noctuids complex development. In control, the degree of the noctuids complex attack was from 65 to 80,5 %. Biological efficiency of Trichogramma evanescens showed improved qualities of cabbage – 21 ha fields varied from 84,2 to88%, thedegree of pest attack varied from 5 to 7%in the variant with Trchogramma evanescens, with common qualities varied from 75,9to80%,thedegreeof pest attack varied from 7 to10%during the peniad ofgenerationsof noctuids complex development. In control,the degree of the noctuids complex attack was from 55 to 65,0%.
