Abstract

                                A host (Corcyra cephalonica / Maruca testulalis) parasitoid (Bracon hebetor) ratio of 2:1 was found to result in higher parasitisation, though the production of females was equal in all the ratios tried. Parasitisation was found to be higher in fourth instar larvae in both the host insects. Three mated female parasitoids per ten host larvae resulted in the best utilisation of the larvae supplied as became evident from the relatively high parasitisation and production of female parasitoid.

Key words : Corcyra cephalonica, Maruca testuialis, Host density, Parasitoid density, Parasitisation, Bracon hebetor
