Apple is an important temperate crop of India and grown mainly in the Western Himalayan region comprising areas of Himachal Pradesh, Jammu and Kashmir, Uttarakhand and some parts of the north-eastern states. Apple occupies 2,41,600 hectare area with a 1,320,590 metric tonnes production in the country (Awasthi and Kamal, 2005). Apple plants are attacked by over 1,000 insects and mites throughout the world and nearly 800 of them are recorded from India (Bhardwaj and Bhardwaj, 2005). Nearly 50,000 species of mites have been described throughout the world so far (Walter and Proctor, 1999) and nearly 660 species described from India of which 30 species have been reported as potential pests (Gupta, 1991).
