Abstract

Predatory potential and stage preference of the reduviid predator,
Allaeocranum quadrisignatum Reuter were studied under laboratory
conditions. The total developmental period on an average was 84.06 days. The younger nymphal instars (I to III) of the predator consumed lesser number of prey than the older (IV & V) nymphal instars. The predatory rate gradually increased as the nymphal development progressed. The nymphs and adults preferred the I and II instar nymphs respectively of Dysdercus cingulatus Fabricius.
