Pyemotes

A genus of mites known for causing dermatitis in humans

Pyemotes is a genus of mites belonging to the family Pyemotidae. These mites are known for their parasitic relationship with insects and their ability to cause dermatitis in humans, commonly referred to as "straw itch mite dermatitis."

Description

Pyemotes mites are microscopic, with adult females measuring approximately 0.2 mm in length. They are characterized by their elongated bodies and lack of eyes. The mites are typically pale in color, making them difficult to see without magnification.

Life Cycle

The life cycle of Pyemotes mites involves several stages: egg, larva, nymph, and adult. The female mites are viviparous, meaning they give birth to live young. The larvae emerge from the female's body and immediately begin to search for a host.

Habitat and Distribution

Pyemotes mites are found worldwide, often in association with stored products such as grains, hay, and straw. They are commonly found in agricultural settings where they parasitize insect hosts, including beetles and moths.

Medical Significance

Pyemotes mites are of medical importance due to their ability to cause dermatitis in humans. The condition, known as "straw itch mite dermatitis," occurs when the mites accidentally come into contact with human skin. The mites inject a toxic saliva that causes intense itching, redness, and swelling.

Prevention and Control

To prevent infestations of Pyemotes mites, it is important to manage and monitor stored products and agricultural environments. Proper storage techniques and regular inspections can help reduce the risk of mite infestations. In cases where mites are present, chemical control methods may be necessary.
