Management potentiality of emulsions based on essential oil of Piper macedoi and Piper arboreum for spider mite: a possible alternative for agroecological control

Abstract

Tetranychus urticae, popularly known as spider mite, is a pest that causes several economic losses to crops. Thus, this work evaluated the effect of essential oils from the leaves of Piper macedoi and Piper arboreum on managing T. urticae. The chemical compounds present in essential oils were identified by gas chromatography. Tests were carried out to evaluate the acaricidal activity by fumigation effect and direct contact with T. urticae. The results showed that LC₅₀ values for the essential oils of P. macedoi and P. arboreum in the fumigation effect were 16.15 and 50.53 µL L⁻¹ air, respectively. Using the contact application route, the LC₅₀ values for the essential oil of P. macedoi was 17.16 µL mL⁻¹, and for P arboreum, it was 15.17 µL mL⁻¹. So, this work showed that essential oils of Piper macedoi and Piper arboreum could be used as possible alternative to managing T. urticae.
