Abstract

The predatory potential of the orthopteran predators viz., Conocephalus longipennis (de Haan), C, maculatus Le Guiilou, Anaxipha longipennis Serv. and Metioche vittaticollis (Stal) against the eggs of rice insect pests was studied under laboratory conditions. M. vittaticollis proved to be an effective predator on the eggs of rice leaf folders (Cnaphalocrocis medinalis (Guenee) and Marasmia patnalis (Bradley) and rice moth, Corcyra cephalonica (Stainton), while C. longipennis and C. maculatus fed voraciously on the eggs of rice stem borer (Scirpophaga incertulas Walker) and rice earhead bug, Leptocorisa acuta (Thunberg), M. vittaticollis did not feed on stem borer eggs while C. longipennis and C. maculatus did not prefer to feed on leaf folder eggs. A. longipennis fed on all the eggs tested along with rice leaves but never on Corcyra eggs.
