The mint plant and its derivatives are common extracts used in the management of plant pests as an alternative to pesticides with saving effects on the environment, plants, animals and humans. The acaricidal activity of mint plant derivatives, (Mentha spicata L.,), (mint oil, mint extract and menthol) were studied under laboratory conditions against adult females of the carmine spider mite, Tetranychus cinnabarinus (Boisduval), the two-spotted spider mite, Tetranychus urticae Koch and the predacious mite, Neoseiulus sp. The results indicated the effectiveness of the mint derivatives especially menthol and mint extract against T. cinnabarinus and T. urticae with a low effect on the predator, Neoseiulus sp. LC₅₀ was 5713.9, 9631.03 and 13782.6ppm for menthol, mint extract and mint oil, respectively, for T. cinnabarinus. However, the LC₅₀ was 5463.2, 7349.7 and 7463.4 ppm for tested compounds mentioned before, respectively, for T. urticae. This revealed that the mint derivatives were more effective on T. urticae than T. cinnabarinus and menthol was more save on the predator Neoseiulus sp. than the other mint derivatives.
