The biology of Chrysoperla zastrowi arabica (Henery et al.) was studied on different prey at the Bio-control Research Laboratory, Department of Entomology, Rajasthan College of Agriculture, Udaipur during October, 2014 to March, 2015. The influence of the eggs, neonate larvae of Corcyra cephalonica (Stainton) and nymphs of five different aphid species [Nyzus nerii (Boyr.), Lipaphis mysimi (Kali.), Aphis gossypii (Glov.), Aphis craccivora (Koch.) and Rhophalosipum maidis (Fitch.)] on different biological parameters was investigated. The maximum incubation period of C. zastrowi arabica 4.50 days was recorded on the larval diet of N. nerii, while the minimum of 14 days on the neonate larvae of C cephalonica. The longest larval period of 13.03 and 13.35 days and pupal period of 10.51 and 10.73 days, for the males and females, respectively, were observed when fed on A. craccivora. Considering the consumption rate of C. zastrowi arabica adults, the females consumed more than males and the highest consumption rate was obtained when reared on the eggs of C cephalonica with the highest pupal weight of 10.39 and 10.73 mg and maximum adult emergence of 92.05 and 95.84 percent for the males and females, respectively.
