The superfamily Tetranychoidea, comprising 1,288 species and numerous pest species. Most of the species that are of major economic importance are contained in two families, the Tetranychidae (spider mites) and the Tenuipalpidae (False spider mites). Spider mites are as an important pest of agricultural crops worldwide, are of great importance in the area of agriculture in terms of damage to crops. During 2015–2016, the fauna of Tetranychidae mites in barley and wheat fields and pastures and orchards (Rosaceae and walnut) in Qorveh, Kurdistan province was investigated. In this order, samples were collected from soil under trees and plants and also aerial parts of plants and taken into the laboratory for processing. Mites were removed from plant leaves with a No. 0 paint brush under a Wild M8 stereomicroscope and also Berlese funnel was used to extract the soil specimens. The specimens were mounted directly on slides in Hoyer’s medium. In total, 9 species belong to 7 genera of spider mites were collected and identified. Among identified species, Tetranychus urticae had the highest relative abundance, 18.75% and Eutetranychus orientalis, The 3rd International Persian Congress of Acarology, 23–25 August 2017 7 Eotetranychus pruni, Bryobia rubrioculus, and Petrobia (Petrobia) latens species were collected from apple, hawthorn, sour cherry and wheat respectively. Identified species are as follows: Bryobia Koch: B. praetiosa Koch, 1836, B. rubrioculus (Scheuten, 1857); Eotetranychus Oudemans: E. pruni (Oudemans, 1931); Eurytetranychus Oudemans: E. amini Khanjani, Khanjani and Seeman, 2017; Eutetranychus Banks: E. orientalis (Klein, 1936); Petrobia Murray: P. (Petrobia) latens (Müller, 1776); Panonychus Yokoyama: P. ulmi (Koch, 1836); Tetranychus Dufour: T. turkestani (Ugarov & Nikolski, 1937), T. urticae Koch, 1836.
