A retrospective analysis of the incidence of reindeer with O. tarandi larvae in the Tazovskiy region of the Yamalo-Nenets Autonomous Area in the period from 2013 to 2018 was carried out. Edemagenosis of the reindeer (n 68096) was diagnosed in a planned slaughter (November-December) when parasite larvae were found on the surface of animal carcasses and skins. The extensiveness of edemagenous invasion ranged from 8.53% in 2015 to 16.45% in 2014, and in 2013 was 11.84%, 2016 – 15.105, 2017 – 11.36%, 2018 – 15.65%. The average long-term extensiveness of reindeer invasion by O. tarandi larvae was 13.05%. To prevent the pathogenetic ef-fect of O. tarandi larvae on the reindeer organism, early chemotherapy is carried out from the last decade of August to the second - third decade of October with prepara-tions based on macrocyclic lactones. Part of the owners of animals do not carry out processing of reindeer, intended for slaughter. In addition to early chemotherapy, in order to increase the effectiveness of measures to combat the defeat of reindeer from O. tarandi, measures should be taken to protect animals from gnat attacks, which will also provide protection from the attacks of gad-flies imago.Edemagenosis of the reindeer is an invasion caused by parasitizing the larvae of Oede-magena tarandi. The infestation of reindeer by this parasite is recorded in all habitats.
