Laboratory trials were carried out to evaluate the influence of seven plant oils on population of two-spotted spider mite Tetranycus urticae Koch (Acari: Tetranychidae) at 30±1 C and 70% ±5 RH. The tested plant oils were Jatropha curcas (Jatropha), Eucalypts globulus (Camphor), linum vsitatissimum (Flax or Linen), Ricinus communis (Castor), Rophanus sativus (Radish), Lupinus termis (Lupine) and Alilum sativum (Garlic). The amounts of plant oils applied were 3, 4, 5, 6, 7, 8, 9 and 10ml. /liter. and sodium laurel sulfate (S.L.S) and Twen80 were used as solvents. The results revealed that, the Jatropha oil was the highest affective oil on the adult females of T. urticae in comparison with other six oils. The concentrations 8, 9 and 10ml. /l. gave high reduction percentages than the low concentrations for all plant oils. All oils were more effective after 72h. from spraying at high concentration. The S.L.S solvent was more effective than Twen80 and other seven tested oils at all concentrations.
