Argas persicus
Argas persicus, fowl tick or poultry tick is a small soft-bodied tick that is found primarily on chickens and other domestic fowl. It was first recorded by Lorenz Oken in 1818 in Meyaneh, Persia, and named Rhynochoprion persicum.
A. persicus has a worldwide distribution in warm climates and is a carrier of avian spirochetosis in chickens.
In addition to chickens and other domestic fowl, A. persicus also feeds on humans, although an immunity has been acquired by some individuals.
