Danger To Livestock
The horn fly, as can be gleaned from its taxonomic designation Haematobia irritans, is an irritant to livestock. Beyond this, incessant biting is compounded by loss of blood, and results in such detrimental effects on host physiology as to include reduction in milk production, efficiency, and rate of gain. If the host is infested with a large number of flies, the resulting skin irritation and wounds may result in the drawing of a secondary infestation of myasis producing flies. There is some controversy over whether the horn fly is a disease vector, with at least one source asserting that the flies can be an intermediate host of Stephanofilaria stilesi, a parasite of cattle in North America.

Famous quotes containing the word danger:
“The danger of the past was that men became slaves. The danger of the future is that men may become robots. True enough, robots do not rebel. But given man’s nature, robots cannot live and remain sane, they become “Golems,” they will destroy their world and themselves because they cannot stand any longer the boredom of a meaningless life.”
—Erich Fromm (1900–1980)
