Predation of Adalia tetraspilota (Hope) (Coleoptera: Coccinellidae) on Green Peach Aphid (Myzus persicae. Sulzer)

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 4th instar was the most efficient consumer with an average of 39.96 ± 1.04 aphids larva-1day-1 followed by 3rd 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 23rd day of its emergence while in case of male it was recorded on 24th day. Female adult consumed more aphids (39.83 ± 11.39 aphids day-1) than male (31.70 ± 8.07 aphids day-1).
