Tliis species is capableof carrying rodent plague, anthrax, septicaemia, nagana, souma, dourine,surra, baleri, and Gambian sleeping sickness, and has been connected byScott with the transmission of equine infectious anemia and seriouslysuspected as a possible carrier of poliomyelitis and pellagra. A very complete bulletin by Bishopp is available for free distribution,describing the life history and control of the stable fly, so that it is not.

Stacked straw which has been wet and partlyrotted and hence is no longer available for stock food is a very favorableplace for the fly to breed. Such straw should be dried as soon as possibleby scattering, and then either be burned or plowed under. The stablefly does not often develop in manure, but where it does it may be con-trolled by measures taken against the house fly. This species is veryannoying to mules, horses, and cattle and often to man
