Abstract

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.
