Abstract

The walnut ( Juglans regia Linn.) an important dry fruit in Himalayas is infested by several insects including Callaphis juglandis Kaltenbach, Chromaphis juglandicola Kaltenbach (Masoodi et ai., 1987) and C.hiraustibis (Kumar and Lavigena, 1970). During the course of a routine faunsitic survey in 1985-86 several predators were observed feeding on C.juglandis of which, a neuropteran Chrysoperla carnea (Stephens) was found to be predominant one. But no attempts seems to have been made to evaluate the predatory efficiency of C. carnea by providing dusky veined walnut aphis (C.juglandis) as prey. Keeping this in view, studies were initiated on the biology and predatory potential of C. carnea on C.juglandis.

Abstract

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).
