Small insects or arthropods which tend to establish a symbiotic relationship with their host, or hosts, which may vary from vegetative to animal, including mammals, birds, and insectivores.
In the list below, are some of the acarocoline mites and ticks that have been identified as existing in nature and their special characteristics.
- Flour Mites, pests that feed on stored cereal products and whose presence can cause allergic reactions in humans.
- Chigger Mites, adults are vegetarian; however, their larvae feed on the skin of other animals, including humans, which causes intense irritations.
- Common Velvet Mites, when young, they live parasitically (feeding on or in another organism) off other arthropods, but then they become predatory when mature (killing and eating other organisms).
- Two-Spot Spider Mites, families that suck the sap of plants which weakens the plants and can transmit viral diseases.
- Varroa Mites are parasitic on honeybees, the young feed on bee larvae and when they are mature, they attach themselves to adult bees and spread to other hives.
- Mange Mites are very tiny and they borrow into the skin of various mammal species, completing their life cycles there where they cause scabies in humans and mange in carnivores.
"Mange" is a disease that causes itchy skin and the loss of fur.
- Chicken Mites are blood-sucking parasites on poultry and they complete their life cycles in crevices away from their hosts, but they come out at night to feed on their former hosts.
- Persian-Fowl Ticks are blood sucking parasites of fowls, including domestic chickens and this oval shaped, soft bodied tick can spread diseases between birds and can cause paralysis.
- Lone-Star Ticks, like other blood-sucking ticks, are common in U.S. woodlands and they can transmit a number of disease-causing microbes.
