Abstract
Biological suppression of the coconut leaf eating caterpillar Opisina arenosella is achieved by nearly 40 species of parasitoids and 20 species of predators. Among these, the bethylid, elasmid and chalcidid parasitoids are the most promising ones. Release of these stage-specific parasitoids at the fixed norms and intervals resulted in significant reduction (94%) in pest population after two years.
