Fecundity and adult longevity of both the sexes in Rhynocoris marginatus (Fabricius) were maximal while total developmental period was minimal when this reduviid predator was reared on larvae of Spodoptera litura (Fabricius) in place of Earias vittella (Boisduval) or Corcyra cephalonica (Stainton). Its intrinsic rate of increase and net reproductive potential were of the highest order if the predator always fed on caterpillars of S. litura.
