The effect of different parasitoid-host ratios on the mass multiplication of a gregarious ectoparasitoid, Allorhogas pyralophagus Marsh was investigated. One parasitoid : one host was found to be the optimum ratio for multiplying the parasitoid on Chilo partellus (Swinhoe) as it resulted in the production of maximum number of cocoons and healthy adults, besides providing a high per cent parasitism.
