Entomophage Trichogramma is one of the most important biological agents which may bе utilized against a complex of pests both in biological control, and in the system of integrated plant protection. Implementation of the tehnologies of production and applicaton of the entomophage Trichogramma evanescens Westwood during the 2015-2017 were carried out under the laboratory conditions and on the maize fields in different households from Republic of Moldova. Biological efficacy of T. evanescens with improved qualities on the maize fields varied 72,0 până la 76,0%, the degree of pest attack varied 2,4 to 7,8%. In control, the degree attack was 44,0 to 50%. Utilizing the eggs Sitotroga сerealella O. irradiated preventively by gamma rays permits the possibility to obtain Trichogramma biological indeces 2-3 times better and the efficiency in the field higher by 10-15%. 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. |
