Argas persicus is a leather tick found in birds in the tropics and subtropics. It affects chickens, ostriches, pigeons and turkeys as well as numerous wild birds. A. persicus damages the host by withdrawing blood and can also cause tick paralysis in chicks. In addition, it is the vector for poultry spiritosis and poultry cholera . Humans are only attacked in the absence of preferred hosts.
Adult ticks are oval and narrow towards the front. They are up to 10 mm long and 6 mm wide. When sober, they are yellow-brown in color, soaked in slate blue. The mouthparts are on the underside and cannot be seen from above. Square fields (“cells”) are formed along the edge of the body.
Life cycle
Females lay eggs in packages of 20 to 100 pieces each in crevices and crevices. Every egg laying is preceded by a meal of blood. After three weeks, the six-legged larvae hatch and look for a host, where they suckle around the clock for about five days, mostly under the wing. They then look for a hiding place in the area and shed their skin within seven days to the eight-legged first nymph stage . The molt to the adults takes place via a further nymph stage. Both nymphs and adults only seek out a host at night and hide during the day.
