European red mite, Panonychus ulmi, a major tree fruit pest attacking apples, stone fruits, and pears, is considered by many growers throughout Pennsylvania to be one of the most important apple pests. The mite was introduced into North America from Europe in the early 1900s and is now established in most fruit-growing areas.
