Abstract

During research it became authentically established about 24 types of two winged blood-sucking insects: Gulicidae, Geratopogonidae, Simuliidae, Tabanidae. Horseflies are dominative type of two winged blood-sucking. We have discovered Europe, Turkestan, Mediterranean and Mongolian faunal types of horseflies. Our analysis of seasonal and daily activity of components of the midges showed that blood-sucking Diptera insects attack agricultural animals during the warm period of the year, causing considerable damage to livestock due to reduction of animal productivity
