Abstract
Pink flowers, Black seed and garlic water extracts tested on adult females on the two-spotted spider mite, Tetranychus urticae Koch (Acari:Tetranychidae) and on the predatory mite, Phytoseiulus pet-wind's A.-H. Percentages of mortality on T urticae were increased gradually with increasing concentration of Pink flowers, Garlic and Black seeds extracts. When compare between the effects of Pink flowers Garlic and Black seeds extracts on the adult females of T. urticae after 1, 3 and 7 days from treatment, Garlic extract, came in the first, then Black seeds extract and in the end came Pink flowers extract it can be concluded that by LCso, 1C90 values and slops. The same results, were found against P. persimllis. In general, T urticae gave more tolerance against the three extracts than P. persimilis.
