Laboratory experiments were conducted to find out the impact of the prey, Periallia ricini third instars stage and deprivation period on the feeding behavior and predatory rate of life stages was evaluated against an economically important lepidopteran pest, P. ricini (Lepidoptera: Arctiidae) under laboratory conditions. Third, fourth, fifth (nymphal instars) and adult (male and female) at 1st, 2ndand 3rd day under laboratory conditions. Results revealed that the third, fourth and fifth instars predator Eocantheona furcellata consumed 2.8, 5.8 and 7.3 preys and completed the stadia period in 3.9, 5.4 and 6.2 days and hence this predator could be used for the biological control agent of P. ricini. However, more studies are necessary to recommend this predator as a biological control agent.
