The percentage of mortality for crawlers (nymphs) stage of oriental yellow scale Aonidiella orientalis when using korea isolates and local isolates of the entomofungus Lecanicillium lecanii was 91.2 and 83.4%, while was 77.5% of local isolates of the fungus Beauveria bassiana after 7 days of treatment. The mortality of adults stage was 78.3, 69.8 and 61.5% for the korea and local isolates of L. lecanii and B. bassiana respectively for the same period. The mortality for korea isolates L. lecanii in concentration 1×109 spore/pore 1ML/ml + summer mineral oil (Nautilus) after 3, 5, 7 and 21 days of treatment in the field test on crawlers stage was 85.1, 89.5, 93.1 and 97.5% respectively. On the other hand the mortality for adults stage in same concentration and isolates was 74.6, 81.8, 86.3 and 90.6% respectively. when using B. bassiana + summer mineral oil the mortality crawlers stage, the results were 73.7, 80.3, 85.6 and 94.4 % respectively, while it was 66.2, 75.4, 80.2 and 86.4% respectively in adults stage.
