Ticks (pí) belong to the family Parasitic mites and ticks. There are two types, there is a shield plate, called a hard tick, and those without a shield are called soft ticks. Body length 2-10mm, blood-sucking swelling as large as red beans, up to 30mm, the world has been found about 800 species, about 700 species of tick family, about 150 species of soft tick family, 1 species of tick family (only in Europe). About 100 species of hard ticks and 10 species of soft ticks have been recorded in China. Ticks are temporary parasites on the surface of many species of vertebrates and are vectors and reservoirs for zoonotic diseases.
The activity time is from April to August, adult parasitism is large mammals, including humans, and is also the main vector of forest encephalitis in China, and can spread Q fever and North Asian tick-borne rickettsiasis, brucellosis, Xinjiang hemorrhagic fever, regressive fever (because of its different species, there are different numbers of boarding times, can be used as a vector for different diseases), hard ticks mostly invade the host during the day, blood sucking time is long, generally take several days. Soft ticks mostly invade the host at night, and the blood sucking time is short, usually a few minutes to 1 hour. Its parasitic site is generally in the area where the skin is thin and not easily scratched. Prefers animals with densely packed skins, such as cats, dogs, sheep, cows, rabbits, birds and other animals. The full groove tick parasitizes the neck, behind the ears, armpits, inner thighs, genitals, and groin of animals or humans.
Ticks are felt by the animal's sweat odor and carbon dioxide, when 15m away from the host, they can be perceived, from passive waiting to active waiting, such as the full ditch hard tick that inhabits the forest area, mostly gathering on the grass tips on both sides of the path and the top of the shrub branches and leaves, and climbing to the host when the host passes and contacts it. The Yadong glass-eyed tick is mostly active on the ground and actively seeks a host; the tick species that inhabit livestock pens are mostly on the ground or climbing on walls and wooden pillars to find a host.
