Abstract:
Implementations of the tehnologies for production and applicaton of the entomophage Trichogramma evanescens Westw. during the 2006 - 2007 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 tomatoes fields of Cooperative Farm „Agrosargal” in the village of Sarata Galbena, region of Hanchesti, in the village of Gura Bicului, region of Anenii Noi. Biological efficacy of Trichogramma evanescens with improved qualities on the tomatoes – 26 ha fields varied 83,0 to 84,8%, the degree of pest attack varied 6 to 10% in the variant with Trchogramma evanescens with common qualities varied 74,0 to 75,8%, the degree of pest attack varied 9 to 16% during the peniad of generations of development of noctuids complex. In control the degree of the noctuids complex attack was 65 to 80,5 %. Biological efficacy of Trichogramma evanescens with improved qualities on the cabbage – 21 ha fields varied 84,2 to 88%, the degree of pest attack varied 5 to 7% in the variant with Trchogramma evanescens with common qualities varied 75,9 to 80%, the degree of pest attack varied 7 to 10% during the peniad of generations of development of noctuids complex. In control the degree of the noctuids complex attack was 55 to 65,0%
