Abstract
Rhynocoris fuscipes effectively suppressed the infestation of Helicoverpa armigera, Nezara viridula and Riptortus clavatus in pigeonpea field cages. Reduced pod and flower damages were observed in R. fuscipes released field cages. R. fuscipes release significantly enhanced the yield of healthy pods (grains). Field observations suggested this predator's pest suppression and grain damage reduction efficacy.
