| Abstract | ||
| The predatory mite Phytoseiulus persimilis (A-H.) was released on eggplants in tested with the two spotted spider mite Tetranychus urticae Koch using three different rates (2, 4 and 6 individuals/ plant) in order to evaluate its effect in reducing numbers of the pest. The predator release decreased numbers of the pest compared with control. Six individuals/ plant enhanced the highest reduction (90.44 and 91.47%) in both seasons, respectively while the lowest was two individuals/ plant (85.16 and 86.58%), table (3). The highest number of predator per leaf was recorded in six individuals/ plant plots; while the lowest was obtained in the control plots. The population density of the predator and its prey was discussed. | ||
