PUPIRO-MARTINEZ, Lester Antonio; MADRUGA, Yanebis Pérez  e  PINO-PEREZ, Oriela. Acaricidal activity of essential oils from species belonging to Myrtaceae, Lamiaceae and Rutaceae families against Tetranychus tumidus Banks. Rev. Protección Veg. [online]. 2018, vol.33, n.3 ISSN 2224-4697.

The aim of this work was to determine the acaricidal activity of essential oils from plant species belonging to the families Myrtaceae, Lamiaceae, and Rutaceae against Tetranychus tumidus Banks. The studied essential oils are marketed in Nicaragua and obtained from eucalyptus (Eucalyptus globulus Labill), Rosemary (Rosmarinus officinalis L.), peppermint (Mentha piperita L.), lemon (Citrus limon (L.) Osbeck), sweet orange (Citrus sinensis (L.) Osbeck), and pepper (Pimienta dioica L. Merr). The acaricidal activity of these oils and Dicofol at 1% was determined by the microimmersion method. All the evaluated essential oils caused mortalities above 50 % in the treated mites. The essential oils of P. dioica, M. piperita and C. lemon showed the highest acaricidal activity; mortality was over 90 % after 72 hours only by P. dioica essential oil.
