“…Both sexes are hematophagous and make numerous visits to their hosts, bit repeatedly before obtaining a full meal. Economic losses in the cattle breeding caused by stables flies are mainly associated with their direct pathogenic effects: a loss of weight, milk production and immunizing defences (Bruce and Decker, 1958;Miller et al, 1973;Campbell et al, 1977Campbell et al, , 2001Wieman et al, 1992) and also by their role in the transmission of virus, bacteria, protozoa and helminths (Zumpt, 1973;Foil et al, 1983;Freitas and Romero, 1991;D'Amico et al, 1996;Foil and Gorham, 2000).
