Evaluation of bioenergetic parameters viz., food consumption, conversion rate, net conversion efficiencies and predatory value of the nymphal instars of Rhynocoris fuscipes Fabricius when fed on Odontotermes obesus Rambur indicated an inverse relationship between the conversion efficiency and predatory value of the nymphal instars of the predator. The conversion efficiency was highest in first instar (47.48%) and the highest predatory value was observed in the fifth instar (10.18mg/day) but it showed the lowest conversion efficiency (12.54%).
