HYPODERMATOSIS OF CATTLEIN THE VALLEY ZONE OF TAJIKISTAN

The article provides data on the infection of cattle with warble flies in the valley zone of Tajikistan. The Hypoderma bovis larvae infection prevalence (IP) in cattle in the valley zone of Central Tajikistan was 10.4–17.1%, and Hypoderma lineatum, 3.0–5.4%, with the infection intensity of 2–18 and 2–15 specimens per one animal. The infection of the animals with warble fly larvae in the valley zone of Southern Tajikistan was 6.6–32.6%, and Hypoderma lineatum larvae, 1.8–2.5%, with the infection intensity (II) of 2–26 and 2–18 specimens. The invasion of the animals by gadfly larvae in the valley zone of Northern Tajikistan was 8.4–11.8%, and by Hypoderma lineatum larvae, 1.8-3.4%, with the infection intensity of 2–16 and 2–10 specimens, respectively. The warble fly infection prevalence in the animals in the plain belts of some regions in Central, Southern and Northern Tajikistan was at a high level. This is explained by the fact that these areas have the most favorable natural and climatic conditions as compared to others. The animal density per 1 hectare of pasture is higher and all cattle are grazed in herds. Thus, warble flies spread widely and cause significant economic damage year after year.
