To investigate the bioecological and morphological features of the sea buckthorn fly, to evaluate the manifestations of parasitism and methods of phytophage control in agrocenoses of the sea buckthorn.Methods. Census of sea buckthorn flies was carried out in agrocenoses of sea buckthorn of the The Institute of Horticulture of the National Academy of Agrarian Sciences of Ukraine, its research network. The studies used sea buckthorn varieties of domestic and foreign selection, which differ in ripeness groups: mid-early, mid-ripening, late-ripening.Results. In the conditions of the Polesia-Forest-Steppe and Forest-Steppe ecotopes, a pest of agrocenoses of the sea buckthorn buckthorn fly was revealed. Bioecological features and morphological characteristics of this pest have been investigated. It has been established that in the conditions of the Western and Northern Forest-steppe of Ukraine, mid-early and mid-season varieties of sea buckthorn suffer from the sea buckthorn fly. A set of measures has been developed for the use of elements of agricultural technology, biological and chemical preparations for the control of sea buckthorn flies in sea buckthorn agrocenoses.Conclusions. It has been shown that the populations of the sea buckthorn fly are numerous on plants of early and mid-season varieties of sea buckthorn, in particular, on such as: Chuiskaya, Pagorbova, Morkvyana, Pavilionna. It was found that the larvae of flies penetrate the fruits, where they feed on the pulp, after which the sea buckthorn fruits become completely unsuitable for fresh consumption and for processing. Research carried out during 2017—2020 in the conditions of the Polesia-Forest-Steppe and Forest-Steppe ecotopes, it was possible to identify varieties of sea buckthorn (Orangevya, Adaptyvna), which are relatively resistant to sea buckthorn fly. It has been established that carrying out agrotechnical measures for loosening the soil in the near-stem part of plants and aisles, sowing perennial herbaceous vegetation in the aisles against the background of changing weather conditions significantly inhibits the development of the sea buckthorn fly and reduces damage to sea buckthorn fruits.
