Order: Astigmata (Sarcoptiformes)
As well as the Order Astigmata, the Subclass Acari consists of the Order Ixodidae containing the hard (Family Ixodidae) and soft (Family Argasidae) ticks, and several other Orders (Mesostigmata, Prostigmata and Orbatidae) containing the parasitic and free-living mites. Other members of the Order Astigmata of importance in veterinary medicine include Chorioptes, Otodectes and Psoroptes.
In Canada, Sarcoptes mites and sarcoptic mange are found on dogs and free-ranging canids, and on pigs and people. Sarcoptes on other susceptible domestic animal hosts, for example cattle, horses and sheep and goats, are probably very rare in Canada or do not occur. It is uncertain whether the mites on these different hosts are members of a single species.

Products containing doramectin (DECTOMAX), ivermectin (VARIOUS) and malathion (MALATHION 50 INSECTICIDE) are approved in Canada for treatment of sarcoptic mange in pigs. It is very important to isolate infested animals, and to treat all pigs at risk.
