| Abstract | ||||
| The efficiency of three methods (Predacious mites, Phytoseiulus persimilis Athias-Henriot, Typhlodromips swiriskii (athias-henriot) and spraying of acaricides Venaldom 48% to control Tetranychus urticae Koch on WinterstarTM cultivar of strawberry was studied at El-Beheira governorate. The obtained data showed that the predatory mite, P. persimilis was the most effective mmethodwhere the reduction % of T. urticae rereached 8.85% followed by the acaricide, Venaldom 48% which achieved 67.67% of reduction while the predatory mite, T. swiriskii was the least effective method to cocontrol. urticae where the reduction percentage was 53.93%. On the other hand, the gains- losses economic were assessment to calculate the profit of strawberry yield / feddan which included local and export production where the predatory mite, P. persimilis method to control of T. urtcae achieved the highest profit (745000 L.E) followed by the predatory mite, T. swirskii method (679000 L.E) while the acaricide method achieved (516,600 L. E). | ||||
