“…There are three chemotypes described for M. suaveolens: pulegone, piperitenone oxide, and piperitenone oxide/piperitone oxide (Oumzil et al, 2002;BoŽović et al, 2015). Previously, M. suaveolens EOs (pulegone and menthone) showed ovicidal and larvicidal effects against the tick Hyalomma aegyptium (Laghzaoui et al, 2019). This species' EOs also have reported insecticidal effects against stored-product pests such as Sitophilus oryzae (piperitenone oxide and piperitenone oxide/piperitenone chemotypes) (Zekri et al, 2013), Rizopertha dominica (piperitenone/pulegone/piperitone) (Benayad et al, 2012), and Triboleum castaneum (menthone/pulegone) (Kasrati et al, 2015) and larvicidal activity against C. quinquefasciatus (piperitenone oxide) (Pavela et al, 2014).…”

Acaricidal and Insect Antifeedant Effects of Essential Oils From Selected Aromatic Plants and Their Main Components

et al. 2021

This work has demonstrated the ixodicidal and insect antifeedant effects of essential oils from 14 experimentally cultivated aromatic plants. The strong ixodicidal and antifeedant oils corresponded to Thymus zygis, Thymus vulgaris, Satureja montana, Oreganum virens, and Mentha suaveolens. The moderately active oils were from Lavandula angustifolia, Mentha piperita, Mentha spicata, Artemisa herba-alba, and Rosmarinus officinalis. The most effective larvicidal and antifeedant compounds were piperitenone oxide, carvacrol, piperitenone, and thymol, explaining the effects of the most active essential oils. The rest of the tested compounds were not ixodicidal or antifeedant. Therefore, the activity of moderately active oils cannot be explained by their main components (linalyl acetate, linalool, menthone, menthol, limonene, camphor, 1,8-cineole, p-cymene, α-pìnene, and carvone), suggesting synergistic effects. Considering the ixodicidal and antifeedant effects of these extracts, the plants have been ranked in relation to Thymus vulgare, a commercial biopesticide ingredient, for their potential as botanical pesticides. T. zygis, S. montana, and M. suaveolens ranked over T. vulgaris as ixodicidal agents and S. montana as insecticidal. Therefore, we propose the plant populations of S. montana, T. zygis, and M. suaveolens tested here for further development as biopesticide ingredients.

Ticks and tick-borne diseases are a significant economic hindrance for livestock production and a menace to public health. The expansion of tick populations into new areas, the occurrence of acaricide resistance to synthetic chemical treatments, the potentially toxic contamination of food supplies, and the difficulty of applying chemical control in wild-animal populations have created greater interest in developing new tick control alternatives. Plant compounds represent a promising avenue for the discovery of such alternatives. Several plant extracts and secondary metabolites have repellent and acaricidal effects. However, very little is known about their mode of action, and their commercialization is faced with multiple hurdles, from the determination of an adequate formulation to field validation and public availability. Further, the applicability of these compounds to control ticks in wild-animal populations is restrained by inadequate delivery systems that cannot guarantee accurate dosage delivery at the right time to the target animal populations. More work, financial support, and collaboration with regulatory authorities, research groups, and private companies are needed to overcome these obstacles. Here, we review the advancements on known plant-derived natural compounds with acaricidal potential and discuss the road ahead toward the implementation of organic control in managing ticks and tick-borne diseases.

“…9 These two species have medicinal applications and have been reported to alleviate diseases such as diarrhea, arthritis, diabetes, 13 and to cure ulcers. 14,15 In addition, essential oils (EOs) of J. phoenicea and J. thurifera have shown antimicrobial, antifungal, and cytotoxic activity, 9,[15][16][17] and EOs from leaves of J. thurifera have been reported to be used for pest control. Thus, these oils were reported to be active as insecticide against Acanthoscelides obtectus, Tribolium castaneum, and Sitophilus oryzae.…”

Objectives: The potential forestry use of Juniperus phoenicea and Juniperus thurifera pruning woods is studied by analyzing the composition of the woods and testing the biological activities of the corresponding components with the ultimate target of finding new biopesticides. Methods: The air-dried wood from each plant was crushed and subjected to hydrodistillation, and the residue was extracted with a Soxhlet apparatus using different solvents. The corresponding extracts were fractionated, and their composition were studied by gas chromatography-mass spectrometry and nuclear magnetic resonance techniques. The ixodicidal and antifungal activities of the different samples obtained were evaluated. Results: The fraction oxygenated of the essential oil from both J. thurifera (cedrol >60%) and J. phoenicea shows a remarkable bioactivity as antitick with EC50 values of 3.4 μg/mg and 10 μg/mg, respectively. Cedrol and methyl hinokiate, present in the hexane extract J. thurifera, show a potent antifungal effect against Aspergillus niger with EC50 values of 45.99 and 52.23 μg/mL, respectively. Conclusions: Pruning woods from these species proved to be renewable and easily accessible sources of bioactive natural products such as cedrol, thujopsene, nootkatone, and totarol.
