Trombiculidae
Trombiculidae
Trombiculidae (pronunciation: trom-bi-cu-li-dae) is a family of mites belonging to the order Acarina. The term is derived from the Greek words "trombos" (a spinning top) and "kule" (bed), referring to the mites' round shape and habitat.
Trombiculidae mites are commonly known as chiggers or harvest mites. They are tiny, red mites that are parasitic in their larval stage. The larvae feed on the skin of various animals, including humans, causing intense itching and dermatitis, known as trombiculiasis.
The adult mites are free-living and feed on plant material. They are found worldwide, but are most common in areas with grassy fields, forests, and other places with vegetation.
Life Cycle
The life cycle of Trombiculidae mites includes egg, larva, nymph, and adult stages. The larvae are the only parasitic stage. After hatching from the egg, the larvae attach to a host and feed on its skin. After feeding, they drop off the host and molt into nymphs, which then molt into adults.
Medical Significance
Trombiculidae mites are of medical importance because their bites can cause intense itching and dermatitis in humans. In some parts of the world, certain species of Trombiculidae mites can transmit a disease called scrub typhus, which is caused by the bacterium Orientia tsutsugamushi.
Prevention and Control
Prevention of trombiculiasis involves avoiding areas where Trombiculidae mites are common, using insect repellents, and wearing protective clothing. If a person is bitten, over-the-counter treatments can help relieve the itching.
