Major insect pests and phytophagous mites associated with deciduous orchards in Afghanistan.
The impact of the major arthropod pests of deciduous fruits was studied in 3 ecological zones (the Pagham valley, Kabul plateau; the Afghan-Turkistan; and the south-western region) of Afghanistan in 1970-72. Cydia pomonella and Yponomeuta padellus were the limiting factors in the production of apples and almonds, respectively, in some areas. Aphis pomi, Eriosoma lanigerum and Quadraspidiotus perniciosus were more important in the south-western region than elsewhere. Tetranychus urticae and Panonychus ulmi were more important in the Afghan-Turkistan region. Rhagoletis pomonella was not as important as C. pomonella.
