“…Comparing the fumigation results obtained here for P. giganteum and P. aracouchine (Table 2) with the literature, it is possible to observe that species studied here were more toxic to T. urticae than P. bahianum (Pontes et al 2010) and P. heptaphyllum (Pontes et al 2007). Previous investigations report that essential oils exhibit toxicity through different contamination pathways, with greater toxicity to T. urtice through fumigation than residual contact (Ribeiro et al 2019), such as the leaf oils from Psidium laruotteanum, Psidium myrsites (Câmara et al 2020), Piper aducum, Melaleuca leucadendra (Araújo et al 2020), Bauhinia rufa, Bauhinia dumosa (Silva et al 2020), Ocotea duckei and Ocotea glomerata (Moraes et al 2017). However, the results of the present study differ from those reported for other oils, as the mites were more susceptible using the residual contact method than fumigation.…”

“…Comparing the results obtained here for sesquiterpenes and monoterpenes, Araújo et al (2020) report similar results regarding the susceptibility of T. urticae to monoterpenes and sesquiterpenes. Several terpenes found in essential oils have been evaluated for their acaricidal potential against T. urticae (Moraes et al 2017;Câmara et al 2020;Silva et al 2020). However, this is the first report on the acaricidal activity of spathulenol.…”

“…Particularly, in the state of Pernambuco, a significant number of plants produce essential oils, but little is known regarding their acaricidal potential. Previous investigations of essential oils from plants that occur in the Atlantic Forest biome have revealed significant properties acting through different pathways for the control of a range of arthropods (Neves & Câmara 2016;Moraes et al 2017;Ribeiro et al 2020;Silva et al 2020).…”

This study describes the chemical composition of essential oils from the leaves of Protium aracouchine and Protium giganteum, evaluates their acaricidal properties and investigates the role of monoterpenes and sesquiterpenes in toxicity to Tetranychus urticae by fumigation and residual contact. The chemical analyses revealed that spathulenol (32.2 ± 1.6%) and β-caryophyllene (27.3 ± 1.1%) were the major constituents of the P. aracouchine and P. giganteum oils, respectively. Both Protium oils were toxic to the mite by fumigation and residual contact. The oils exhibited the same level of toxicity by residual contact, where the P. aracouchine oil was fivefold more toxic by fumigation than the P. giganteum oil. Among the chemical constituents tested, the mite was more susceptible to β-caryophyllene and spathulenol, independently of the method used. The blends prepared with terpenes selected from the P. giganteum oil had the same level of toxicity as the essential oil. The investigation of the role of terpenes in the form of blends revealed that β-caryophyllene and spathulenol contributed significantly to the acaricidal effects. These results suggest that the preparation of artificial oils is a promising strategy for the control of T. urticae.
