Joshi PC, Khamashon L and Kaushal BR

Studies on prey consumption of larvae and adults of Adalia tetraspilota (Hope) (Coleoptera: Coccinellidae) was conducted in the laboratory on green peach aphid, Myzus persicae (Sulzer) (Homoptera: Aphididae). In larval form 4^th instar was the most efficient consumer with an average of 39.96 ± 1.04 aphids larva^-1day^-1 followed by 3^rd instar with an average of 20.90 ± 0.58 larva^-1day^-1. Feeding potentials of adult coccinellids increased with increase in age. In female the highest consumption of aphids was recorded on the 23^rd day of its emergence while in case of male it was recorded on 24^th day. Female adult consumed more aphids (39.83 ± 11.39 aphids day^-1) than male (31.70 ± 8.07 aphids day^-1).
