| Abstract | ||||
| The effect of releasing of predacious mite Amblyseius swirskii Athias-Henriot in different levels for reducing the population density of tenuipalpid mites, (Tenuipalpus punicae Pritchard & Baker and Tenuipalpus granati Sayed) on pomegranate seedlings were studied. The results showed that, the highest rate of reduction of the double release and high level was after seven weeks after release with percentage 91.82% reduction. The highest rate of reduction of the double release and low level was after five weeks after release with percentage 86.27% reduction. The highest rate of reduction of the single release and high level was after three weeks after release with percentage 85.10% reduction. The highest rate of reduction of the single release low level was after three weeks after release with percentage 76.96% reduction. The mean of all levels was (56.03 and 75.81) and (78.51 and 82.62) for single and double release at low and high releasing, respectively. This confirms the success of using the predacious mite A. swirskii for controlling the population density of phytophagous mites on pomegranate orchards. | ||||
