Essential Oil Composition and Acaricidal Activity of Schinus Terebinthifolius from Atlantic Forest of Pernambuco, Brazil against Tetranychus Urticae

Abstract

The compositions of the essential oils from unripe (UFr) and ripe (RFr) fruits of Schnus terebinthifolius were analyzed by GC and GC/MS. The major compound identified in both oils was limonene (UFr = 44.1 ± 1.3%; RFr = 31.8 ± 1.2%), followed by α-phellandrene (15.7 ± 0.4%) in the UFr oil and thujene (21.7 ± 0.9%) in the RFr oil. Repellent and toxicity activities of the two oils were also evaluated, and the results compared with eugenol. The UFr oil was more active in the fumigation tests (LC50 = 1.46 μL/L of air), whereas the RFr oil was more active in the sealed dishes (SD) than open dishes (OD) contact assay (LC50 = 3.04 μL/cm2) and not significantly different from eugenol. Both oils exhibited significant repellent activity comparable with that of eugenol. The results suggest that the repellent activity of these oils in association with its toxicity could be a great advantage for the integrated management of T. urticae.

Acaricidal properties of essential oils from agro‐industrial waste products from citric fruit against Tetranychus urticae

“…However, studies have been conducted on the effect of EOs from other plants species on T. urticae through residual contract, reporting both better and worse results in comparison with the present findings. For instance, the oils from Piper aduncum (LC 50 = 7.17 μl/ml ≅ 7.00 mg/ml) (Araújo et al, ) and oils from the green (LC 50 = 7.44 μl/ml) and ripe (LC 50 = 7.29 μl/ml) fruits of Schinus terebinthifolius (Nascimento, Camara, & Moraes, ) were more toxic than the four Citrus oils investigated herein, whereas the oil from Vitex agnus‐castus (Neves & Camara, ) was less toxic. In other studies using the same population of T. urticae , the oils from Lippia gracilis (LC 50 = 29.70 μl/ml) (Born, da Camara, de Melo, & de Moraes, ) and Aristolochia trilobata (LC 50 = 62.54 mg/ml) (de Melo, Camara, Silva Lima, Moraes, & Alves, ) were more toxic than the C. reticulata , C. reticulata × C. sinensis and C. aurantiifolia oils, but less toxic than the C. limon oil.…”

Phytochemical screening, antioxidant and antibacterial activities of extracts prepared from different tissues of Schinus terebinthifolius Raddi that occurs in the coast of Bahia, Brazil

“…[ 6 ] Essential oil extracted from the seeds is rich in mono and sesquiterpenes which confers several biological activities to the oil. [ 7 8 9 10 ] The resin produced by S. terebinthifolius is used in the treatment of rheumatism and buboes. [ 11 ] Stem bark and leaves are also used against many diseases of the urinary tract system, in the treatment of menstrual disorders and inflammations in general.…”

Chemical composition of essential oil from ripe fruit of Schinus terebinthifolius Raddi and evaluation of its activity against wild strains of hospital origin

“…In the study carried out by Barbosa et al (2007) on the analysis of the variation in volatile composition of the EO from the fruits of S. terebinthifolius vs. time of extraction, three of the four main chemical constituents obtained after one hour of extraction were identified as: α-pinene (6.48%), α-phellandrene (7.45%) and δ-3-carene (17.15%). Nascimento et al (2011) , in their work with the EO of ripe fruit of Schinus , obtained limonene (31.8%), thujene (21.7%), sabinene (15.8%) and α-phellandrene (11.9%) as major compounds.…”
