Abstract

This study was aimed to evaluating the role of Acramite acaricide in normal and nanosized in addition to extracts of sour orange peels Citrus aurantium, harmal seeds Peganum harmala and sidr leaves Ziziphus spina-christi in reducing the population density of two-spotted spider mite (TSSM) Tetranychus urticae and the effect of prior treatments in decreasing the yield loss percentage in the eggplant crop. The cumulative relative efficiency for Acramite nano size 0.4 g/L was 87.7% with significantly outperformed from all other treatments, followed by Acramite nano size 0.2 g/L and Acramite normal size that was 82% and 73.2%, respectively, while was 70%, 67% and 66.8 for  alcoholic harmal extract, essential oil of sour orange and alcoholic sidr extracts,  respectively
