Amphitetranychus viennensis (Zacher, 1920) View in CoL

The polyphagous and globally widespread species, A. viennensis , was first reported by Carmona in 1964 (as Tetranychus viennensis ) on Malus sylvestris , Prunus persica , Pyrus communis ,

and subsequently on other Rosaceae ( Carmona and Dias 1980) . Despite being considered an important pest in apple orchards ( Sobreiro 1993), its populations have been systematically declining since the 1960s ( Carmona and Dias 1980), and less than 1% of peach ( P. persica ) orchards were infested in a study conducted in the south and centre of Portugal ( Ferreira and Carmona 1997). A. viennensis is, consequently, represented by a small number of specimens in the INIAV acarological collection.
