Abstract
An experiment was conducted to evaluate the efficacy of Chrysoperla carnea (Steph.) against two hard scale insects Parlatoria proteus (Curtis) and Fiorinia phoenicis (Balachowsky); Hemiptera:Diaspididae, in the nursery of El-Orman Botanical Garden Giza Governorate by releasing 5,10 and 15 individuals of 2nd larval instar of C. carnea and counts were taken 15, 30 and 45 days after treatment. Results showed that there were an effective reduction percentage in population of both scale insects. The mean of reduction percentages after 45 days after treatment in case of P. proteus different stages were 52.54, 68.95 and 77.14% for 1st, 2nd and 3rd treatments, respectively. While mean of reduction percentages of different stages of F. phoenicis recorded 58.38, 59.03 and 65.34% for 1st, 2nd and 3rd treatments, respectively.
