Abstract : Eight essential oils (EOs) as well as 13 single terpenes were studied for their nematicidal activity against Meloidogyne incognita , for three immersion periods (24, 48, and 96 h). The EOs were isolated from eight Greek Lamiaceae species: Melissa officinalis , Sideritis clandestina , Origanum dictamnus , Ocimum basilicum , Mentha pulegium , Origanum vulgare , Vitex agnus castus , and Salvia officinalis . The EOs nematicidal activity was correlated to their chemical composition as well as to the pure terpenes' activity tested individually. Clear dose and time response relationships were established. The EOs of O. vulgare, O. dictamnus, M. pulegium, and M. officinalis exhibited high nematicidal activity against M. incognita, and the EC(50) values (96 h) were calculated at 1.55, 1.72, 3.15, and 6.15 muL/mL, respectively. The activity of the nematicidal terpenes was found to decrease in the order l-carvone, pulegone, trans-anethole, geraniol, eugenol, carvacrol, thymol, terpinen-4-ol, and the respective EC(50) values (24 h) were calculated in the range of 115-392 mug/mL. Terpenes tested individually were more active than as components in EO, implementing antagonistic action.

Abstract : The screening for bioactive principles from several Chinese medicinal herbs showed that the essential oil of Cymbopogon distans aerial parts possessed strong repellency against the booklouse, Liposcelis bostrychophila , and the red flour beetle, Tribolium castaneum . A total of 36 components of the essential oil were identified by GC and GC-MS. trans-Geraniol (16.54%), (R)-citronellal (15.44%), (+)-citronellol (11.51%), and α-elemol (9.06%) were the main components of the essential oil followed by β-eudesmol (5.71%) and (+)-limonene (5.05%). From the essential oil, four monoterpenes were isolated by bioassay-guided fractionation. The compounds were identified as limonene, citronellol, citronellal, and trans-geraniol. Geraniol and citronellol were strongly repellent against the booklouse, L. bostrychophila, whereas citronellal and limonene exhibited weak repellency against the booklouse. Geraniol and citronellol exhibited comparable repellency against the booklouse relative to the positive control, DEET. Moreover, geraniol and citronellol exhibited stronger repellency against the red flour beetle than DEET, whereas the two other compounds showed the same level of repellency against the red flour beetle compared with DEET.

Abstract : The screening for bioactive principles from several Chinese medicinal herbs showed that the essential oil of Cymbopogon distans aerial parts possessed strong repellency against the booklouse, Liposcelis bostrychophila , and the red flour beetle, Tribolium castaneum . A total of 36 components of the essential oil were identified by GC and GC-MS. trans-Geraniol (16.54%), (R)-citronellal (15.44%), (+)-citronellol (11.51%), and α-elemol (9.06%) were the main components of the essential oil followed by β-eudesmol (5.71%) and (+)-limonene (5.05%). From the essential oil, four monoterpenes were isolated by bioassay-guided fractionation. The compounds were identified as limonene, citronellol, citronellal, and trans-geraniol. Geraniol and citronellol were strongly repellent against the booklouse, L. bostrychophila, whereas citronellal and limonene exhibited weak repellency against the booklouse. Geraniol and citronellol exhibited comparable repellency against the booklouse relative to the positive control, DEET. Moreover, geraniol and citronellol exhibited stronger repellency against the red flour beetle than DEET, whereas the two other compounds showed the same level of repellency against the red flour beetle compared with DEET.

Abstract : A tool for integrated pest management is the use of essential oils (EOs) and plant extracts. In this study, EOs from Tagetes lucida , Lepechinia betonicifolia , Lippia alba , Cananga odorata , and Rosmarinus officinalis , species grown in Colombia, were analyzed by gas chromatography-mass spectrometry. These oils as well as several of their constituents were tested for repellent activity against Tribolium castaneum , using the area preference method. The main components (>10%) found in EOs were methylchavicol, limonene/α-pinene, carvone/limonene, benzyl acetate/linalool/benzyl benzoate, and α-pinene, for T. lucida, L. betonicifolia, L. alba, C. odorata, and R. officinalis, respectively. All EOs were repellent, followed a dose-response relationship, and had bioactivity similar to or better than that of commercial compound IR3535. EOs from C. odorata and L. alba were the most active. Compounds from EOs, such benzyl benzoate, β-myrcene, and carvone, showed good repellent properties. In short, EOs from plants cultivated in Colombia are sources of repellents against T. castaneum.

Abstract : A tool for integrated pest management is the use of essential oils (EOs) and plant extracts. In this study, EOs from Tagetes lucida , Lepechinia betonicifolia , Lippia alba , Cananga odorata , and Rosmarinus officinalis , species grown in Colombia, were analyzed by gas chromatography-mass spectrometry. These oils as well as several of their constituents were tested for repellent activity against Tribolium castaneum , using the area preference method. The main components (>10%) found in EOs were methylchavicol, limonene/α-pinene, carvone/limonene, benzyl acetate/linalool/benzyl benzoate, and α-pinene, for T. lucida, L. betonicifolia, L. alba, C. odorata, and R. officinalis, respectively. All EOs were repellent, followed a dose-response relationship, and had bioactivity similar to or better than that of commercial compound IR3535. EOs from C. odorata and L. alba were the most active. Compounds from EOs, such benzyl benzoate, β-myrcene, and carvone, showed good repellent properties. In short, EOs from plants cultivated in Colombia are sources of repellents against T. castaneum.

Abstract : A crude glycosidic fraction was prepared from fresh tea leaves and treated with the crude tea enzyme, fractions of cis-3-hexenol, linalool oxide I (cis-furanoid), linalool oxide II (trans-furanoid), linalool, methyl salicylate, geraniol, benzyl alcohol, and 2-phenylethanol were monitored to be the major aglycone moieties by analyzing the released volatiles. The amount of the released aglycone moieties is 5.8 times higher than those in free form. For investigation of the functions of the glycosidically bound form aroma constituents in tea leaves, their antifungal activities were determined by antifungal assay. Geraniol, linalool, methyl salicylate, benzyl alcohol, and 2-phenylethanol exhibited significant antifungal activities toward Colletorichum camelliae Massea, although cis-3-hexenol and linalool oxides showed weaker activities by comparison. Among them, geraniol was shown to be the most potential antifungal substance with a MIC value of 440 microg/mL. The crude glycosidic fraction prepared from tea leaves also exhibited significant antifungal activities in a wide range of concentrations from 2 to 25 mg/mL in a PDA medium. It was deduced that the glycosidically bound volatiles are formed and stored in the intact tissue of tea leaf and hydrolyzed by the actions of both the endogenous and the exogenous glycosidases to release volatiles as antifungal substances when exposed to Colletorichum camelliae Massea. The results suggested that the higher content of the bound form geraniol in tea leaves of var. sinensis might be responsible for their stronger antipathogen properties toward tea leaf blight, as opposed to those of var. assamica.

Abstract : Recent studies proved that monoterpenoids could be an alternative to synthetic insecticides against stored-product pests. For that reason, it is necessary to learn the mode of action of these monoterpenoids. Inhibition of acetylcholinesterase (AChE) activity as a possible mode of action by 8 monoterpenoids which cause high mortality of three stored-product insect pests, Sitophilus oryzae L. (Coleoptera: Curculionidae), Rhyzopertha dominica Fabricius (Coleoptera: Bostrichidae) and Cryptolestes pusillus Schönherr (Coleoptera: Cucujidae) and the role of these monoterpenoids as inhibitors were examined. Inhibition of AChE was measured by colorimetric method where a chemical reaction with enzyme acetylcholinesterase, a substrate (acetylthiocoline iodide), the Ellman's reagent and each monoterpenoid as inhibitor was carried out. The majority of monoterpenoids tested inhibited the enzyme acetylcholinesterase; fenchone, S-carvone and linalool produced the highest inhibition. Furthermore, it was observed that fenchone, γ-terpinene, geraniol and linalool showed a reversible competitive inhibition at least at the enzyme's hydrophobic active site. S-carvone, estragole and camphor produced a mixed inhibition for this enzyme binding to either the free enzyme or the enzyme-substrate complex which links to a different site from the active site where the substrate binds. No inhibition of enzyme acetylcholinesterase by E-anethole was observed.

Abstract : The fungitoxicity data of some monohydric alcohols on the mycelial growth inhibition of Colletotrichum gloeosporioides were subjected to quantitative structure-activity relationship (QSAR) studies. The very large variation in the median effective concentrations ranging from >24000 mg/L [pEC(50) (mol/L) = 0.11] in the case of methanol to <100 mg/L [pEC(50) (mol/L) = 3.27] in the case of citronellol was found to depend mainly on changes in calculated partition coefficients (CLogP) of the compounds. The other three factors that affected the variation in fungitoxicity are the number of hydrogen atoms on the carbon bearing the hydroxyl group (N(H)), which determines the class of the alcohol to be primary, secondary, or tertiary, the number of double bonds (N(=)), and the branching of the alkyl moiety. Because many compounds in the set under study belonged to homologous series, there was a collinearity between CLogP values and Kier's molecular connectivity values (chi), which are usually used as branching indices. The problem of collinearity between CLogP values and branching indices was overcome by taking the relative molecular connectivity (chi(rel)), which is defined as the ratio of molecular connectivity of the alcohol under consideration to the molecular connectivity of the corresponding straight-chain primary alcohol with the same number of carbon atoms. Apart from the excellent correlations obtained in the equations, the credibility of the QSAR model could also be demonstrated by its application to published data taken from the literature.

Abstract : The bioactive hexane extract of Daucus carota seed yielded 2,4,5-trimethoxybenzaldehyde (1), oleic acid (2), trans-asarone (3), and geraniol (4). Compounds 1-4 were evaluated for their mosquitocidal, nematicidal, antifeedant, and antimicrobial activities. Only trans-asarone was active in the assays performed, causing 100% mortality to fourth-instar mosquito larvae, Aedes aegyptii, at 200 microg mL(-1) and the nematodes Caenorhabditis elegans and Panagrellus redivivus at 100 microg mL(-1). In feeding trials, trans-asarone also caused significant weight reductions of the caterpillars Helicovarpa zea, Heliothis virescens, and Manduca sexta when incorporated into artificial diet at a concentration of 100 microg mL(-1). Also, it exhibited slight activity at 100 microg mL(-1) against the yeasts Candida albicans, Candida parapsilasis, and Candida kruseii.

In feeding trials, trans-asarone also caused significant weight reductions of the caterpillars Helicovarpa zea, Heliothis virescens, and Manduca sexta when incorporated into artificial diet at a concentration of 100 microg mL(-1). Also, it exhibited slight activity at 100 microg mL(-1) against the yeasts Candida albicans, Candida parapsilasis, and Candida kruseii.

Abstract : The bioactive hexane extract of Daucus carota seed yielded 2,4,5-trimethoxybenzaldehyde (1), oleic acid (2), trans-asarone (3), and geraniol (4). Compounds 1-4 were evaluated for their mosquitocidal, nematicidal, antifeedant, and antimicrobial activities. Only trans-asarone was active in the assays performed, causing 100% mortality to fourth-instar mosquito larvae, Aedes aegyptii, at 200 microg mL(-1) and the nematodes Caenorhabditis elegans and Panagrellus redivivus at 100 microg mL(-1).

Issue : 12

Authors : Han J, Kim SI, Choi BR, Lee SG, Ahn YJ.
Abstract : BACKGROUND: This study was aimed at assessing the fumigant toxicity of 14 essential oil constituents from lemon eucalyptus, Eucalyptus citriodora Hook, and another ten known compounds to females of acaricide-susceptible, chlorfenapyr-resistant, fenpropathrin-resistant, pyridaben-resistant and abamectin-resistant strains of Tetranychus urticae Koch. RESULTS: Menthol (LC(50) , 12.9 µg cm(-3) ) was the most toxic compound, followed by citronellyl acetate (16.8 µg cm(-3) ), against the susceptible females. High toxicity was also produced by β-citronellol, citral, geranyl acetate and eugenol (LC(50) , 21.7-24.6 µg cm(-3) ). The fumigant toxicity of these compounds was almost identical against females from either of the susceptible and resistant strains, indicating that the compounds and acaricides do not share a common mode of action or elicit cross-resistance. CONCLUSION: Global efforts to reduce the level of highly toxic synthetic acaricides in the agricultural environment justify further studies on materials derived from lemon eucalyptus oil, particularly menthol and citronellyl acetate, as potential acaricides for the control of acaricide-resistant T. urticae as fumigants with contact action.
