| چکیده | ||
| The susceptibility of the ladybird Chilocorus bipustulatus (L.) to different concentrations (0.5%, 1.0% and 1.5%) of volk oil was studied. The 0.5% concentration was found to be harmless, while the 1.0% and 1.5% concentrations were slightly harmful. The adult males and females as well as the 3rd instar larvae of ladybird's mean feeding on Aonidiella orientalis (Newstead) were about 6.15, 6.37 and 7.09 numbers in 24 hours respectively. The simultaneous application of volk oil and ladybird's release is recommended for an effective control of A. orientalis. | ||
