The European red mite, Panonychus ulmi (Koch) first described in 1878 from Italy as rose mite. Tetranychus pilosus (C and F) was reported as pest of apple and other delicious fruits from Oregon, USA in 1911 and Ontario, Canada in 1912 (Ewing 1912; Caesar 1915). Later it became a common pest in the Pacific North, West, Central California, Indiana and Utah (Newcomer and Yothers, 1929). It was recorded in Australia in 1975 and became a major pest of apple in all major fruit growing areas of Australia by 1986( Bower and Thwaite, -1986). Earlier the pest was known as Paratetranychus pilosus C and F and with many common names such as imported red spider in USA, plum spider mite in Ontario, fruit tree red mite in UK and fruit tree spinning mite in Sweedan.
