Trombiculidae is a taxonomic family of parasitic mites commonly known as chiggers. These tiny arthropods belong to the subclass Acari and order Trombidiformes. They are ectoparasites that primarily infest vertebrates, including humans, birds, reptiles, and mammals.
Chiggers, specifically members of the Trombiculidae family, have a distinctive life cycle. The larvae, which are the parasitic stage, attach themselves to the host's skin and feed on tissue fluids. The larvae are typically red or orange in color and measure only about 0.15 to 0.3 millimeters in size, making them barely visible to the naked eye. They are most commonly encountered in forests, grasslands, and areas with high humidity.
The parasitic bite of chiggers can cause skin irritation and a condition known as trombiculiasis or chigger dermatitis. The bite site forms a small, itchy, red welt on the skin, and symptoms may include intense itching, swelling, and sometimes secondary infections.
Prevention and control methods for chigger bites include avoiding areas where they are likely to be found, wearing protective clothing, using insect repellents, and taking a shower immediately after exposure to remove unattached chiggers. Treatment for chigger bites typically involves topical corticosteroids or antihistamines to alleviate itching and discomfort.
In conclusion, Trombiculidae refers to the family of parasitic mites commonly known as chiggers, which infest vertebrates including humans. These tiny arthropods cause skin irritation and can be found in various habitats, favoring humid environments.
