| Abstract | ||||
| The management of the two spotted spider mite, Tetranychus urticae Koch, an economically important agricultural pest global wise feeding on a wide range of host plant, is mainly based on the use of acaricides. Mite reduction % after 3 and 7 days of spray and effect on some biological aspects of treatments with eight different acaricides were studied. After 3 days of treatment, the reduction of T. urticae reached to a maximum (96.64%) with the use of Vermin while a minimum (59.64%) was obtained with Komodo. After 7 days of treatment, the reduction of T. urticae reached to a maximum (97.97%) with the use of Buprolord and to a minimum (68.20%) with Vermin. The longest life cycle (16.1 days) was obtained with Solofan treatment while the shortest was (11.2 days) with Galesco and Komodo. The experiments were performed under laboratory conditions (25±1°C, 80±5% RH and 16:8 h (L: D). Individuals which treated with Galesco, Solofan and Vermin passed through the preoviposition period and did not complete their life cycle while individuals treated with Komodo reached oviposition period then died. | ||||
