| Abstract | ||
| An experiment was carried out to investigate the effect of some biopesticides for controlling the olive black scale insect, Saissetia oleae (Olivier) on olive trees at Giza Governorate, Egypt during April, 2010. Four biopesticides (Biover, Stanes-biocatch, Stanes-biomagic and Bioranza) and one plant extract (Nimbecidine) were tested. The obtained results showed that all tested biopesticides and one extract were able to decrease the infestation with the olive black scale insect on olive trees through the three post treatment counts. Data clearly showed no significant differences among their efficiency (over 85%) and Nembicidine gave 80%. | ||
