The article presents long-term observations on the establishment of the summer dates of blood-sucking Dipterans commonly referred to as "gnats" (horseflies, mosquitoes, midges, biting midges) and gadflies in the south of the Tyumen region. For each natural and climatic zone of the region, the authors identified the periods of mass flight of these insects, during which it is necessary to carry out measures to protect cattle. For subzones of the southern taiga and small-leaved aspen and birch forests, such protective measures should be organized from the last days of May to the end of August, and in the forest-steppe zone from the beginning of June to the end of the first five days of September. %U https://easletters.com/article/protection-of-beef-cattle-from-gnats-and-gadflies-in-the-south-of-the-tyumen-region-at47mqr4lvfelen
