The predatory potential of aphid lion, Chrysoperla zastrowi sillemi (Neuroptera: Chrysopidae) against Aphis punicae in pomegranate was studied and the observation showed that all the larval stages of the predator were found to feed on A. punicae. Furthermore, the third instar grub of C. zastrowi sillemi with the developmental period of 3.4 days had consumed a maximum of 106.3 aphids followed by second and first instar grubs of the predator which consumed a maximum of 68.1 and 30.7 aphids during their development period of 3.2 and 2.7 days, respectively. Further, single C. zastrowi sillemi grub was found to consume a total of 205.1 aphids during its total larval period of 9.3 days. The results obtained indicate the potential of C. zastrowi sillemi as an effective predator of pomegranate aphid.
