Abstract: Aim. To optimize the integrated protection of winter wheat against wheat thrips due to growing resistant wheat varieties of intensive type by estimating resistance level of varieties against the phytophage and determining its nature.Material and methods. Experimental researches were carried out in 2014–2015 at the V.M. Remeslo Myronivka Institute of Wheat of NAAS. Level of resistance against wheat thrips in ecological testing nursery was estimated for 20 new varieties of winter wheat bred at Myronivka.Accounting wheat thrips population size was carried out in the late phases of booting and milk ripeness of grains.Results. Resulted from analyses of additive (total) resistance of winter wheat varieties against wheat thrips one highly resistant variety (resistance score 9–8) Remeslivna was found in 2014, but in 2015 it has shown itself to be resistant variety. Instead, in 2015 variety Myronivska rannostyhla was identified as highly resistant, although in the previous year it was classified as resistant variety. The varieties, such as Vesta, Smuhlianka, Monotyp, Natalka, Myrliena, Lehenda Myronivska and Berehynia Myronivska were stably resistant (7–6). Dostatok, Svitanok Myronivskyi and other varieties, excepting weak resistant variety (3–2) Myrkhad, were middle-resistant (5–4).Conclusions. In the last decade wheat thrips (Haplothrips tritici Kurd.) has become extremely wide-spreading and dangerous pest of winter wheat. Expression of plant resistance to phytophages was combined into four types: antixenosis, antibiosis, avoidance and tolerance. According to the research there were identified 1 highly resistant, 12 resistant, 6 medium resistant and 1 weak resistant variety. The varieties showing resistance to wheat thrips are characterized with early and mid-ripeness, glume closing, properly filled kernels with shallow crease, high protein and gluten content in grains.
