This study was carried out under laboratory and field conditions in Fayoum governorate, Egypt to study the susceptibility of Tetranychus urticae Koch to two different acaricides. Spraying of Aakomic 1.8% EC (abamectin) and Ortus 5.0% EC (fenpyroximate) was conducted on bean plants Phaseoulus vulgaris L. at 0.4 and 0.5 respectively. Laboratory observations showed that there is no significant difference in susceptibility between different stages of T. urticae in Aakomic treatment, while moving stages were more susceptible than eggs in Ortus treatment. Generally, % reduction of mites increased gradually 3 days after application (78.57%) to reach maximum after 14 days (96.65%) with Ortus. No significant differences was found in case of Aakomic. Field studies showed similar result in case of Aakomic. However, the adult stage was more susceptible to Ortus compared with eggs, larvae and nymphs. The trend of susceptibility to application in the lab. also occurred in the field.
