Psoroptes is a genus of mites known for being external parasites that primarily affect mammals, including livestock like sheep and cattle. These mites are responsible for causing skin conditions such as scabies and mange, leading to irritation and discomfort in the affected animals. The life cycle of Psoroptes involves several stages, including eggs, larvae, nymphs, and adults. They thrive in warm, humid environments and can spread rapidly among animals, making effective management and treatment essential to prevent outbreaks and ensure animal welfare.
