Ectoparasites are responsible for economic losses to cattle and sheep producers.
Direct losses are a result of discomfort and damage caused by the parasites. Discomfort results in drops in milk production and retarded growth rates. Ticks, blowflies, sheep keds and mites cause direct damage to hides and wool or damage resulting from rubbing and scratching due to pruritis.
Indirect losses are due to diseases transmitted by ectoparasites.
