Abstract
It was demonstrated that the aphid species Schzarium graminium and Sitobion avenae reached the highest degree of population density in the wheat crop in the first decade of June (18,0 and 16.6% respectively). It was found that aphids and entomophages reached the highest degree of development when the gray crop entered the phenological phase of buttoning. Thus, the population density of aphids was 23,0 % and that of entomophages – 16,0%. 6 species of natural entomophages were highlighted (Aphidina evri Haliday, 1834; Ephedrus sp.; Lysiphlebus sp.; Diaeretiella rapae M. Intosh, 1855; Praon volucre Haliday, 1833; Ephedrus persicae Froggatt, 1904), which can control the population density of of the 3 most widespread species of aphids (Schzarium graminium L.; Sitobion avenae F.; Myzodes persicae Sulz.) in the wheat crop.
