Studies conducted to determine the optimum conditions for mass production of Cotesia plutellae Kurdj. (Hymenoptera: Braconidae) revealed that host: parasitoid ratio of 100 second instar larvae: one-day old female of the parasitoid and rearing the parasitized larvae at 30°C and 75 percent relative humidity were the conducive conditions. The extent of parasitisation was 90.6 percent and duration of development was 12 days.
