Abstract
Stomoxys flies are mechanical vectors of various pathogens existing in the blood and skin of livestock, but sometimes humans. In addition to their immune suppressive effects, they have quite a few disturbance effects on skin lesions, reduction of food intake, stress and blood loss. To protection from flies, the gathering of animals also contribute development of mechanical transmission of pathogens. Dirofilaria sp, Onchocerca sp, Habronema microstoma, Besnoitia sp and Trypanasoma sp are transmitted by Stomoxys. Stomoxys calcitransindicate a cosmopolitan distribution is known as a profile of an significant vectoring transmitting pathogens to the animals and humans. Due to importance of this subject, a review has been made concerning the morphology, biology, medical importance, control methods of the Stomoxys flies so that future investigations may benefit.
