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 : Essential oils of Salvia macrochlamys and Salvia recognita were obtained by hydrodistillation of dried aerial parts and characterized by gas chromatography and gas chromatography-mass spectrometry. One hundred and twenty identified constituents representing 97.7% in S. macrochlamys and 96.4% in S. recognita were characterized, and 1,8-cineole, borneol, and camphor were identified as major components of the essential oils. The oils were evaluated for their antimalarial, antimicrobial, and antifungal activities. Antifungal activity of the essential oils from both Salvia species was nonselective at inhibiting growth and development of reproductive stroma of the plant pathogens Colletotrichum acutatum, Colletotrichum fragariae, and Colletotrichum gloeosporioides. S. macrochlamys oil had good antimycobacterial activity against Mycobacterium intracellulare; however, the oils showed no antimicrobial activity against human pathogenic bacteria or fungi up to a concentration of 200 microg/mL. S. recognita oil exhibited a weak antimalarial activity against Plasmodium falciparum.

Title : Toxicity of monoterpenes against larvae and adults of Colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

First Page : 278

Authors : Kordali S, Kesdek M, Cakir A.
Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Abstract : Fungicidal activity of Curcuma longa rhizome-derived materials against Botrytis cineria, Erysiphe graminis, Phytophthora infestans, Puccinia recondita, Pyricularia oryzae, and Rhizoctonia solani was tested using a whole plant method in vivo. It was compared with synthetic fungicides and four commercially available compounds derived from C. longa. The response varied with the tested plant pathogen. At 1000 mg/L, the hexane extract of C. longa showed fungicidal activities against E.graminis, P. infestans, and R. solani, and the ethyl acetate extract of C. longa showed fungicidal activities against B. cineria, P. infestans, Pu. recondita, and R. solani. Curcumin was isolated from the ethyl acetate fraction using chromatographic techniques and showed fungicidal activities against P. infestans, Pu. recondita, and R. solani with 100, 100, and 63% control values at 500 mg/L and 85, 76, and 45% control values at 250 mg/L, respectively. In the test with components derived from C. longa, turmerone exhibited weak activity against E. graminis, but no activity was observed from treatments with borneol, 1,8-cineole, sabinene, and turmerone. In comparison, potent fungicidal activity with chlorothalonil against P. infestans at 50 mg/L and dichlofluanid against B. cinerea at 50 mg/L was exhibited. These results may be an indication of at least one of the fungicidal actions of curcumin derived from C. longa.

Abstract : The essential oils from leaves and inflorescences of Hyptis martiusii Benth were analyzed by GC-MS. Twenty-six compounds representing 93.2% of the essential oil of leaves were characterized; Delta-3-carene (22.5%), 1,8-cineole (24.27%), beta-caryophyllene (6.15%), and bicyclogermacrene (6.32%) were found as the major components. In the essential oil of inflorescences 27 compounds representing 87.7% of the oil were identified. The major components were Delta-3-carene (13.5%), alpha-pinene (5.78%), beta-caryophyllene (6.59%), viridiflorene (8.25%), and germacrene B (5.21%). The essential oil of leaves and 1,8-cineole showed pronounced insecticidal effect against Aedes aegypti larvae and Bemisia argentifolii, the vectors of dengue fever and white fly fruit plague, respectively.

Abstract : The essential oils from leaves and inflorescences of Hyptis martiusii Benth were analyzed by GC-MS. Twenty-six compounds representing 93.2% of the essential oil of leaves were characterized; Delta-3-carene (22.5%), 1,8-cineole (24.27%), beta-caryophyllene (6.15%), and bicyclogermacrene (6.32%) were found as the major components. In the essential oil of inflorescences 27 compounds representing 87.7% of the oil were identified. The major components were Delta-3-carene (13.5%), alpha-pinene (5.78%), beta-caryophyllene (6.59%), viridiflorene (8.25%), and germacrene B (5.21%). The essential oil of leaves and 1,8-cineole showed pronounced insecticidal effect against Aedes aegypti larvae and Bemisia argentifolii, the vectors of dengue fever and white fly fruit plague, respectively.

Title : Quantitative structure-activity relationships of monoterpenoid binding activities to the housefly GABA receptor.

Abstract : BACKGROUND: Monoterpenoids are a large group of plant secondary metabolites. Many of these naturally occurring compounds have shown good insecticidal potency on pest insects. Previous studies in this laboratory have indicated that some monoterpenoids have positive modulatory effects on insect GABA receptors. In this study, the key properties of monoterpenoids involved in monoterpenoid binding activity at the housefly GABA receptor were determined by developing quantitative structure-activity relationship (QSAR) models, and the relationship between the toxicities of these monoterpenoids and their GABA receptor binding activities was evaluated. RESULTS: Two QSAR models were determined for nine monoterpenoids showing significant effects on [³H]-TBOB binding and for nine p-menthane analogs with at least one oxygen atom attached to the ring. The Mulliken charges on certain carbon atoms, the log P value and the total energy showed significant relationships with binding activities to the housefly GABA receptor in these two QSAR models. CONCLUSIONS: From the QSAR models, some chemical and structural parameters, including the electronic properties, hydrophobicity and stability of monoterpenoid molecules, were suggested to be strongly involved in binding activities to the housefly GABA receptor. These findings will help to understand the mode of action of these natural insecticides, and provide guidance to predict more monoterpenoid insecticides.

Title : Fumigant toxicity of lemon eucalyptus oil constituents to acaricide-susceptible and acaricide-resistant Tetranychus urticae.
Year : 2011
Volume : 67
Issue : 12
First Page : 1583

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.
