Among the insect pests of apple orchards, San Jose scale Quadraspidiotus pemiciosus (Comstock) is a key pest in all the applegrowing areas of Jammu and Kashmir. The pest sucks the sap, thereby debilitating plant health and reducing the quality of the fruit. Several predators and parasitoids have been reported on 'San Jose scale in India out of which two aphelinid parasitoids Encarsia perniciosi Tower and Aphytis proclia Walker are of considerable importance (Masoodi and Trali, 1987; Bhagat et al., 1988).

The pest sucks the sap, thereby debilitating plant health and reducing the quality of the fruit. Several predators and parasitoids have been reported on 'San Jose scale in India out of which two aphelinid parasitoids Encarsia perniciosi Tower and Aphytis proclia Walker are of considerable importance (Masoodi and Trali, 1987; Bhagat et al., 1988).
