Abstract
Citrus brown mites, Eutetranychusorientalis seemed to be one of the most common phytophagous species found in citrus orchards. Four methanol plant extracts such as Myrrh, Ginger, Black cumin and Rosemary were used to screen their effects on the life cycle of citrus brown mites. Rosemary extract showed the highest activity on the rate of hatching ability and egg laying behavior. The four plant extracts showed the moderate effect on the egg viability, where methanol extracts of Myrrh showed the highest effect on the egg viability. Both Rosemary and Black cumin extracts showed the highest activity on the control of reproductive potentials of citrus brown mites.
