Abstract

Of the primary aphidiid parasites of aphids of Rosa spp. encountered in Kashmir Valley. Proan volucre (Haliday) was dominating with wide occurrence and Aphidius avenae Haliday was relatively scarce. Host range, seasonal occurrence and population density of the hyperparasites: Alloxysta sp., Asaphes suspensus(Nees), Coruna spp. and Prionomitus sp. have been studied. The population of A. suspensus was high and of Prionomitus sp. low in various habitats surveyed.
