In the present study, methanol, acetone and petroleum ether extracts of olive leaves were investigated for their insecticidal activity against Myzus persicae and deterrent effect on Phthorimaea operculella under laboratory conditions. Different concentrations 0.1%, 1% and 10% were implemented in the experiment. The results revealed that acetone and methanol extracts caused 100% mortality of M. persicae at 10%. Tests on P. operculella generated a very pronounced deterrence of oviposition and larval penetration at 10%. Data indicate that, the acetone extract proved to be most deterrent against larval penetration at 10 % in comparison with other tested extracts and concentrations with 71.7% of deterrent index. Moreover, the highest deterrent effect of oviposition was recorded to acetone extract with 25.9%, 65.2% and 93.3% at 0.1, 1 and 10%, respectively. Therefore, this study provides first report on the insecticidal and deterrent activities of olive leaf extracts against M. persicae and P. operculella.
