Abstract

A study on the development and predatory potential of Mallada astur (Banks) indicated that developmental time of M. astur larvae was longer when the nymphs of spiralling whitefly, Aleurodicus dispersus Russell were provided as compared to developmental period when provided with eggs of rice moth, Corcyra cephalonica (Stainton). The predatory larvae took a mean of 15.6 days on the whitefly nymphs but only 13.19 days on rice moth eggs. The number of whitefly nymphs preyed during first, second and third instar larvae was 60.2±3.21, 36.4±3.26 and 138.4±6.55 nymphs, respectively. The chrysopid larva consumed a total of 234.9 nymphs of A. dispersus during its larval development.
