Some Observations on Brown Mirid Bug Tytthus parviceps Reuter a Predator of Rice BrownPlanthopper, Nilaparvata lugens Stal

摘要

Many workers observed the predatory activity of mirid bugs against rice hoppers (Bae and Pathak, 1966). The bugs prey on the eggs, nymphs and adults of rice leaf and planthoppers and have been considered as effective predators (Staphley, 1976). Of the mirid bugs, Cyrto-rhinus lividipennis Reuter is widely distributed and most common; the other mirids preying on the planthoppers being Tytthus parviceps Reuter and T. chinensis (Stal) (Stanley, 1976; Manjunath et al., 1978; Basilo and Heong, 1990).
