“…C. dubium was rich in caryophyllene oxide (64.4%), an approved food flavoring agent. Recent studies showed that caryophyllene oxide and its analogues effectively control house dust mites [25]. It is noteworthy that caryophyllene oxide rich Cinnamomum species were not reported from the Western Ghats previously.…”

The volatile chemical profiles of 8 wild Cinnamomum species (C. dubium Nees, C. litseifolium Thwaites, C. mohanense Gangapr. et al., C. palghatensis Gangop., C. riparium Gamble, C. travancoricum Gamble, C. walaiwarense Kosterm. and C. wightii Meissn.) and two chemotypes (C. agasthyamalayanum Robi et al. and C. keralaense Kosterm.) from the Western Ghats, south India were reported for the first time. A total of 112 constituents belonging to monoterpenoid, sesquiterpenoid and phenyl propanoid classes were identified from the leaf essential oils by GC-FID and GC-MS analytical methods. Monoterpenoids and sesquiterpenoids were the major class of volatile compounds distributed in most of the Cinnamomum species studied. The study lead to the identification of natural sources of aroma compounds such as 1,8-cineole (C. mohanense), 1,4-cineole (C. wightii), safrole (C. walaiwarense) and benzyl benzoate (C. keralaense). Two new chemotypes of Cinnamomum species viz; C. agasthyamalayanum phellandrene-eugenol type and C. keralaense benzyl benzoate type were also discovered from the Western Ghats. The interrelationships between the studied species were discussed based on the volatile chemical profiles.

“…Moreover, the acaricidal activities of L. japonicum oil against three acaridae and pyroglyphid mites were attributed to borneol and β-caryophyllene. The acaricidal activities of borneol and β-caryophyllene against three acaridae and pyroglyphid mites have been reported previously (Lee et al, 2010;Oh et al, 2014). Nevertheless, this study is the first report on the acaricidal effects of L. japonicum oil against three acaridae and pyroglyphid mites.…”

The composition of the essential oil of Ligustrum japonicum leaves was determined by GC-MS analysis. The major constituents of L. japonicum leaf oil were germacrene D (40.50%), α-pinene (13.63%), (−)-β-elemene (6.42%), β-caryophyllene (5.73%), and δ-cadinene (5.47%). The acaricidal activities of L. japonicum oil were evaluated against acaridae and pyroglyphid mites. In the fumigant bioassay, the LD 50 values of L. japonicum oil were 16.48, 12.38, and 15.63 µg/cm 3 against Tyrophagus putrescentiae, Dermatophagoides farinae, and D. pteronyssinus, respectively. In the contact bioassay, the LD 50 values of L. japonicum oil were 8.02, 5.02, and 7.67 µg/cm 2 against T. putrescentiae, D. farinae, and D. pteronyssinus, respectively.Keywords acaricidal activity · Ligustrum japonicum · pyroglyphid mites · Tyrophagus putrescentiaeThe significance of acaridae mite, Tyrophagus putrescentiae (storage mite), and pyroglyphid mites, Dermatophagoides farinae and D. pteronyssinus, with regard to allergic diseases is known in the world (Arlian, 1989). These mites are the most serious factors of allergens, causing asthma and atopic dermatitis . Acaridae and pyroglyphid mites have been known to be the hygienic pests for storage products and apartment dusts and are important allergen factors within stored grains and apartment environments in the humid areas (Azima et al., 2011). Stored grains, wall-to-wall carpeting, and space heating in the lifestyle of humans have promoted favorable environmental conditions for the growth of acaridae and pyroglyphid mites (Yang et al., 2013). The population of acaridae and pyroglyphid mites has preferentially been controlled by synthetic acaricide such as N,N-diethyl-mtoluamide (DEET). However, repeated attempts of synthetic acaricides have resulted in residual toxicity and resistance (Jeon and Lee, 2011). These problems have pointed the need for the development of effective acaricides against acaridae and pyroglyphid mites .Ligustrum japonicum Thunb. (Oleaceae) is known as Wax Privet originating from Korea and Japan. This tree has a thick covering of green leaves throughout the whole year, making it an evergreen plant. The L. japonicum flowers are followed by black fruits in June. The fruit is an oval drupe ripening in purple-black color with a glaucous bloom in December. Previous studies have indicated that L. japonicum flowers are abundant in active materials responsible for aldose reductase inhibition (Papoti et al., 2011), antibacterial (Doh, 2010, and antioxidant (Papoti et al., 2011) effects. It contains α-terpinolene, hotrienol, 2-methoxyphenol, benzenemethanol, and tricosane (Lim et al., 2008). However, there are a few studies on the acaricidal effects of the L. japonicumderived materials against acaridae and pyroglyphid mites. To analyze the composition of the essential oils obtained from L. japonicum leaves, the volatile constituents of L. japonicum oil were identified by GC-MS to assess the acaricidal effects. Sample preparation and GC-MS analysis. L. japonicum leaves were purch...

Both oils also have a small amount of β-caryophyllene oxide which previous work has shown to have acaricidal activity against Dermatophagoides farinae and D. pteronyssinus (house dust mites) (Oh et al 2014). In Libya, in the past, people built their tents beside S. persica plants to avoid insects and Acari (El-Mogrebi 2003).…”

Essential oils extracted from the leaves of Libyan Rosemary (Rosmarinus officinalis L.), and Miswak (Salvadora persica L.) were evaluated for their acaricidal and repellent effects on Ixodes ricinus L. nymphs (Acari: Ixodidae) using a bioassay based on an 'open filter paper method'. Rosmarinus officinalis leaf essential oil diluted to 0.5 and 1 µl/cm 2 in acetone exhibited, respectively, 20 and 100% tick mortality after about 5 h of exposure. A total of 50 and 95% of I. ricinus nymphs were killed by direct contact with the oil when exposed to lethal concentrations (LC) of 0.7 µl/cm 2 (LC 50) and 0.95 µl/cm 2 (LC 95), respectively. The LC 50 (0.5 µl/cm 2) was reached before the end of the first 24 h of exposure time (ET), as tick mortality at 24 h was 60%. Salvadora persica leaf essential oil at 1 µl/cm 2 showed a significant repellency effect against I. ricinus nymphs at 1.5 h ET. A 95% repellency was observed at a repellent concentration (RC 95) of 1 µl/cm 2 of S. persica, but no significant mortality was recorded at this dose of S. persica oil. Gas chromatography-mass spectrometry analyses showed that the main monoterpenes in both oils were 1,8-cineol, α-pinene, and β-pinene, although in markedly different proportions. These results suggest that essential oils have substantial potential as alternative approaches for I. ricinus tick control.
