Mealy bug (Drosicha dalbergia, Green) is one of the most serious pests of apple and almond in Kashmir. Second instar nymphs hibernate in the rhizosphere of its host plant. Activity is resumed during March and partial migration of the insect to the aerial parts of host plant takes place during April-May. All the adults migrate back to the rhizosphere of the host plant during July. The adults and nymphs have been recorded upto the depth of 27 inches. The bugs suck sap from the tender roots, branches and stem of the host plant and weaken it. There is no literature available on the management of this species of mealy bugs. Evaluation of some insecticides for its management was therefore carried out under high hill conditions.
