الملخص الانجليزي
The acaricidal activity of some essential and fixed oils against the two-spotted spider mite, Tetranychus urticae Koch were
evaluated at 15 C, 27 C and 35 C under laboratory conditions. The essential oils namely, rosemary (0.125%), garlic
(0.5%), jojoba (0.25%) and the fixed vegetable oil (soyabean and sunflower oil (0.125%)) were tested in this study. The
acaricidal activity was evaluated by studying the mortality, fecundity and fertility rates of the adult females at three
different temperatures. Results showed that highest mortality rates among T. urticae were recorded for garlic oil followed
by vegetable, jojoba and rosemary oils at 15 C and for garlic, jojoba, rosemary and vegetable oils at 35 C. Interestingly,
no mortality rates were recorded for all the tested oils at 27 C. At 15 C, garlic oil caused a significant effect on both the
fecundity and fertility rates as compared to the other oils. On the other hand, at 27 C and 35 C, most of the tested oils
caused significant effects on the fecundity and fertility rates. In conclusion, the temperature is apparently a key factor
regulating the acaricidal activity of the tested oils and attention must be given to this factor during field applications
