Abstract

The Coconut black-headed caterpillar, Opisina arenosella Walker is a notorious pest of coconut in Kerala. Most damage is recorded from India and Srilanka. Caterpillars of this oecophorid prefer to live in a gallery of frassy material and they feed on leaf chlorophyll matter. O. arenosella causes significant yield losses in coconut crops, but there is a lack of scientific information whether this pest can be controlled effectively using biocontrol agents. This paper describes the effects of the parasitoid, Bracon brevicornis (Hymenoptera: Braconidae) on larvae of O. arenosella. The adult B. brevicornis gave excellent control of larvae of O. arenosella. These findings suggest that, repeated release of  B. brevicornis  was very effective. By controlling O. arenosella, using B. brevicornis is 78% of  recovery was finally attained.
