TARSONEMOIDEA (Itch Mites) (Contact) Please CLICK on
Image & underlined links to view: Only a few species are parasitic on
humans. Pediculoides ventricosus Newport, known as the "Grain Itch Mite," is
probably cosmopolitan in distribution by 2016. It feeds on larvae of insects in grains, cotton or their
products. In the life cycle the eggs
hatch within the female's body where the young mites are kept until
maturity. A single prolific female
can sustain over 260 sexually mature offspring. In plant material the numbers of these mites are extremely
high. The itch mite, Psoroptes communis, is a nonburrowing species that attacks sheep
primarily, but also humans working in the area. The hair follicle mite, Demodex folliculorum also common on domestic animals may affect humans
in a closed environment. Humans become attacked when coming
into contact with mite-infested material.
A severe rash covering the entire body can result followed by fever
and sweating. As with many of these
mites, avoidance is the best treatment even though medicinal applications are
sometimes required, usually on the advice of a physician. CONTROL Folk remedies that involve bathing in
warm soapy water have provided some relief, although taking care to avoid
infested areas is still the best remedy.
In severe cases consultation with a physician is always advisable. = =
