| Abstract | ||||
| Laboratory trials of feeding potential of Chrysoperla carnea (Steph.) (No choice) were estimated at (25 ± 2 °C, 65± 5% R. H.). Data revealed that the larval stage of C. carnea (Steph.) fed on egg masses of Corcyra cephalonica (St.) Pectinophora gossypiella (Saund.) and Sitotroga cerealella (Oliv.) consuming all over its 3 larval instars an average of 493.6±50.32, 654.3±32.54and 673.9±31.52 eggs (total consumed) for the three prey species, respectively, with total larval corresponding periods 8.7 ± 0.94, 9.5 ± 0.97 and 9.6 ± 1.17 days. Statistical analysis of the obtained data obviously cleared that there were significance differences between the mean numbers of consumed C. cephalonica eggs and that of P. gossypiella and S. cerealella; on the other hand there was no significance of C. carnea total larval period when feeding upon each of the three preys. In addition, host preference (Free Choice) revealed that C. cephalonica was the most preferred host to C. carnea. The predator consumed (13.2 ± 6.01, 77.9 ± 31. 14 and 264.1 ± 68.8 eggs of C. cephalonica for the 1st, 2nd and 3rd predator larval instars, respectively). S. cerealella was the least preferred host, whereas the respective predator larval instars consumed (0.8 ± 1.75, 27.9 ± 24.56 and 63.3 ± 47.2 eggs). Also, numbers of attacked eggs by the predator was recorded. Eggs of Rice moth were the highest attacked with Green Lacewing larvae while eggs of Angoumois grain moth were the least. This result needs more experimental efforts to earn its advantage in certain predacious performance. | ||||
