It is shown that agents of hypodermatosis of cattle are: ordinary subcutaneous gadfly (string) Hypoderma bovis de Geer and South subcutaneous gadfly (pediatric) Hypoderma lineatumde Villers. The data on the ubiquitous prevalence of hypodermatosis in all agricultural zones of the Stavropol territory are presented. It was established that hypodermatosis in cattle is more often recorded in pasture than stall-walking rearing. The extent of invasion in animals kept in farms of different forms of ownership is 15.4-42.5 %, the intensity of invasion varies within 18.5-29.5 specimens/head. It is emphasized that the activity of skin gadflies in the biocenosis during the day and spring-summer period is regulated by environmental conditions. Populations gadflies in the Stavropol region demonstrated a certain species ratio of Hypoderma bovis (De Gee – 64.7%, Hypoderma lineatum DeVillers and 33.7%. The factors of population size regulation of H. bovis and H. Lineatum were studied.
