“…In this regard, phenylpropenes, abundantly available secondary metabolites present in many essential oils bearing plants, are interesting candidates for such studies. Several phenylpropenes such as eugenol (Hamraoui and Regnault-Roger 1997;Isman 2000;Kim et al 2003), isoeugenol , carvacrol (Ahn et al 1998;Isman et al 2001), -asarone (Saxena et al 1977;Streloke et al 1989;Paneru et al 1997;Park et al 2003), anethole (Hummelbrunner and Isman 2001; Kim and Ahn 2001;Passreiter et al 2004) are reported active against insects/mites. However, only limited studies on structure activity relationship of phenylpropenes against insects/mites has been reported (Lee et al 1997;Khambay and Jewess 2000;Harmatha and Nawrot 2002;Park et al 2003;Regnault-Roger et al 2004).…”

Bioactivity and structure–activity relationship of natural methoxylated phenylpropenes and their derivatives against Aphis craccivora Koch (Hemiptera: Aphididae)

In the light of recent increased interest in developing plant based secondary chemistry into products suitable for integrated pest management, the objective of the present study was to investigate the bioactivity in Weld simulated conditions and structure-activity relationship of some natural phenylpropenes and their related analogues (1-6) against Aphis craccivora. The activities of diVerent compounds varied depending on the substitution of the functional groups and the side chain attached to the aromatic ring of the phenylpropene. Dimethyleugenol (5) showed maximum activity among all tested phenylpropenes with LC 50 values 880 and 2,047 ppm against nymphs and adults respectively. Present study showed that phenylpropenes appear to be promising natural insecticides and may hold potential for identiWcation of new lead structures against A. craccivora. The activity of the most active phenylpropene (5) was comparable with that of the chemical pesticide (dimethoate).

“…microplus, it is observed that the acaricidal potentiality is higher in A. calamus followed by A. indica and A. squamosa. This may be due to the presence of essential oil in the rhizome which contains monoterpene hydrocarbons, acorine, trimethylamine, acorenone, calamendiol, a selinene, α-calcorene, camphone shybunone, sequestrine ketone (trans-or alpha) asarone (2,4,5-trimethoxy-1-propenyl benzene), beta-asarone (cis-isomer) etc., of which beta-asarone is the major chemical constituent (Streloke et al 1989;Raina et al 2002). In the present study, α-asarone is identified and may have probably played an active role in killing treated ticks.…”

In vitro and in vivo efficacy of Acorus calamus extract against Rhipicephalus (Boophilus) microplus

To develop a environment friendly control measure against cattle tick, Rhipicephalus (Boophilus) microplus, medicinally important plants were identified and extracts were prepared. Twelve 95% ethanolic, thirteen 50% hydroethanolic and nine hot water extracts were prepared and tested against laboratory reared homogenous colony of R. (B.) microplus. Amongst the 34 extracts, 26 extracts showed no mortality within 72 h of application while 12.0 ± 4.9% to 35.0 ± 9.6% mortality of treated ticks was recorded in other extracts. Of the effective extracts, the extract prepared from rhizome of Acorus calamus proved highly efficacious and 100% final mortality within 14 DPT was recorded. The LC85 value of the extract was determined as 11.26. In vivo experiments confirmed the efficacy of the extract up to 42%, and repeat application was required after 7 DPT. The extract was found safe and no reaction was observed when animals were treated with 50% of the concentration, which was five times of the concentration used for in vivo studies. The possibility of using the extract for the control of cattle tick is discussed.

“…Phytochemicals from plant essential oils have varying rates of vapor pressure [11]. Vapor pressure of cis -asarone is 1.3 × 10 −3 mm Hg at 20 °C [12], and this low vapor pressure might be one reason why valerian oil and cis -asarone show weak fumigant toxicity at 2 days after treatment. Among the essential oil components, benzyl alcohol, acetophenone, 1-phenyl-1-ethanol, hydrocinnamyl alcohol, and trans -cinnamyl aldehyde exhibited strong fumigant toxicity against Japanese termites 2 days after treatment at 2.5 mg/L air.…”

This study investigated the fumigant toxicity of oriental sweetgum (Liquidambar orientalis) and valerian (Valeriana wallichii) essential oils and their components against the Japanese termite (Reticulitermes speratus). The fumigant toxicity of oriental sweetgum and valerian oil differed significantly according to exposure time. Oriental sweetgum showed toxicity at short exposure times (2 days), and the toxicity of valerian oil was high 7 days after treatment. The main constituents of oriental sweetgum and valerian oils were tested individually for their fumigant toxicity against Japanese termites. Among the test compounds, benzyl alcohol, acetophenone, 1-phenyl-1-ethanol, hydrocinnamyl alcohol, trans-cinnamyl aldehyde, trans-cinnamyl alcohol, cis-asarone, styrene, and cis-ocimene showed toxicity against Japanese termites 7 days after treatment. Hydrocinnamyl alcohol and trans-cinnamyl alcohol were found to be the major contributors to the fumigant antitermitic toxicity of oriental sweetgum oil. The acetylcholinesterase (AChE) inhibition activity of two oils and their constituents was tested to determine their mode of action. Only cis-ocimene showed strong AChE inhibition activity with an IC 50 value of 0.131 mg/mL. Further studies are warranted to determine the potential of these essential oils and their constituents as fumigants for termite control.
