“…Therefore, citral is likely the active substance responsible for the anthelmintic activity. Citral has antibacterial (FISHER et al, 2007), antifungal (YAMASAKI et al, 2007) and insecticidal activities (YANG et al, 2005), and it is also effective against the phytonematodes Bursaphelenchus xylophilus and Meloidogyne incognita (BAUSKE et al, 1994;CHOI et al, 2007) and the larvae of the nematode Anisakis simplex (HIERRO et al, 2006). Citral has also been reported as a predominant compound in Eucalyptus staigeriana essential oil and may be responsible for the activity of that essential oil against the gastrointestinal nematodes of goats (MACEDO et al, 2010).…”

Parasitic nematodes are of major economic importance in livestock. An alternative for the control of parasites is phytotherapy. This study evaluated the efficacy of Cymbopogon citratus decoction (CcD), C. citratus essential oil (CcEo) and citral against Haemonchus contortus using in vitro egg hatch test (EHT) and larval development test (LDT) and an in vivo test using a Meriones unguiculatus (gerbil) model. The effect of 800 mg/kg CcEo was evaluated in gerbils that had been artificially infected with 5,000 third-stage H. contortus larvae. The effective concentrations required to inhibit 50% (EC50) of egg hatching were 0.46, 0.14 and 0.13 mg/mL for CcD, CcEo and citral, respectively. The EC50 values in the LDT were 5.04, 1.92 and 1.37 mg/mL for CcD, CcEo and citral, respectively. H. contortus population in the group treated with C. citratus essential oil was reduced by 38.5% (P< 0.05) in comparison to the control group. These results suggest that it may be possible to use C. citratus essential oil to control of H. contortus parasite of small ruminant.Keywords: Phytotherapy, anthelmintic, Meriones unguiculatus, in vitro, citral. ResumoO parasitismo por nematoides tem grande importância econômica no rebanho. Uma alternativa para o controle de parasitas é a fitoterapia. Este estudo avaliou a eficácia do decocto de Cymbopogon citratus (DCc), do óleo essencial de C. citratus (OECc) e do citral contra Haemonchus contortus utilizando o teste in vitro de eclosão dos ovos (TEO) e o teste de desenvolvimento larval (TDL) e um teste in vivo com modelo Meriones unguiculatus (gerbil). O efeito de 800 mg/kg de OECc foi avaliado em gerbils infectados artificialmente com 5000 larvas de terceira fase de H. contortus. As concentrações efetivas necessárias para inibir 50% (CE50) da eclosão dos ovos foram 0,46; 0,14 e 0,13 mg/mL para DCc, OECc e citral, respectivamente. Os valores da CE50 no TDL foram de 5,04; 1,92 e 1,37 mg/mL para DCc, OECc e citral, respectivamente. No grupo tratado com óleo de C. citratus a população H. contortus foi reduzida em 38,5% (P < 0,05) em comparação com o grupo controle. Estes resultados sugerem que pode ser possível a utilização de óleo essencial de C. citratus para controle de H. contortus, parasita de pequenos ruminantes.Palavras-chave: Fitoterapia, anti-helmínticos, Meriones unguiculatus, in vitro, citral.

“…This difference could of course be due to other different physiological/biochemical characteristics. 11) Essential oils have been utilized as insecticides, antifeedants, and repellents with a wide variety of target insects [12][13][14][15][16][17][18][19][23][24][25][26][27] ; however, one study that tested 96 herb extracts found that while Japanese mint oil had a strong repellent effect against B. germanica, the essential oils of grapefruit, lemon, and lime did not show strong repellent activity. 28) This is in contrast with our results, but the previous study was performed by a classical assay method based on the behavior of cockroach groups, and this may have been affected by the chemical factors associated with aggregation.…”

Repellent activity of citrus oils against the cockroaches Blattella germanica, Periplaneta americana and P. fuliginosa

et al. 2009

The repellent efficacy of 17 essential oils against the German cockroach, Blattella germanica was examined using a T-tube olfactometer. Five oils repelled B. germanica with good efficacy, ranging from 70.0 to 96.7%. Four of these oils, grapefruit, lemon, lime, and orange, were from the citrus family Rutaceae. These citrus essential oils showed similar repellent activity against two more cockroach species, such as Periplaneta americana and P. fuliginosa. Gas chromatography (GC) and GC-mass spectrometry analyses revealed that the major components responsible for the repellent activity of the citrus oils were limonene, b-pinene and g-terpinene. Limonene appears to be the main component responsible for the repellent activity rather than b-pinene and g-terpinene. The repellent efficacy of these components varied with different doses and the cockroach species tested. It is likely that minor components of the oils also contributed to the overall repellent activity of citrus essential oils, except orange oil. The activity of orange oil is almost solely attributed to the activity of limonene. Also, the repellent activity of citrus oil and that of each of the terpenoids makes little difference to the efficacy of a repellant against the three species of cockroaches.

“…Las propiedades insecticidas de los aceites esenciales contra poblaciones adultas de mosquitos han sido reportadas por varios investigadores (Yang et al, 2005;Mansour, Messcha, & Gengaihi, 2000;Panella et al, 2005). Se sabe que Lantana camara posee actividad contra plagas que atacan granos almacenados, plagas de cultivos vegetales, mosquitos y larvas, así como también presentan actividad antifúngica y repelente (Sharma et al, 1988;Dua, Pandey, Singh, Sharma, & Subbarao, 2003).…”

RESUMENEl uso indiscriminado de plaguicidas sintéticos en el control de plagas y enfermedades que afectan los cultivos, la salud humana, y el medio ambiente, han conducido a resistencia por parte de insectos y presencia de residuos tóxicos en alimentos. Esto ha propiciado la necesidad de desarrollar enfoques alternativos para el control de especies plaga. En el presente estudio se ha investigado la actividad insecticida del aceite esencial de hojas de Lantana camara sobre el insecto modelo Drosophila melanogaster. Se aisló aceite esencial de las hojas de L. camara utilizando el método de hidrodestilación. El bioensayo se realizó por el método de la OMS para determinación de actividad adulticida contra mosquitos y artrópodos. Diferentes compuestos fueron identificados por análisis de cromatografía de gases -espectrometría de masas. El valor de la CL 50 del aceite fue 0.56 mg cm -2 mientras que el valor de la CL 95 fue 0.96 mg cm -2 sobre Drosophila melanogaster. El rendimiento de aceite esencial de hojas obtenido por hidro-destilación fue 0.022% w/w. El análisis por cromatografía de gases -espectrometría de masas del aceite esencial mostro 66 picos, donde Germacren D (19.29%), B-Cariofileno (14.55%), α-Humuleno (9.51%), Biciclogermacren (8.94%), Germacren B (7.26%) y Terpineno (5.62%) estuvieron presentes en mayores cantidades y contribuyeron con el 56.21% del total de los constituyentes. El aceite esencial de hojas de L. camara mostró actividad adulticida sobre la especie de mosca Drosophila melanogaster y podría ser utilizado para el desarrollo de insecticidas a base de aceite como complementario a los insecticidas sintéticos para el control de moscas causantes de importantes pérdidas económicas. Palabras clave: L. camara, aceite esencial, CG-MS, CL 50-CL95, bioensayo, insecticida. ABSTRACTThe indiscriminate use of synthetic pesticides in the control of pests and diseases affects crops, human health, and the environment, and lead to insect resistance and the presence of toxic residues in food. Previous generated the need to develop alternative approaches to pest species control. In the present study the insecticidal activity of the essential oil of leaves of Lantana camara on the insect model Drosophila melanogaster has been investigated. Essential oil was isolated from L. camara leaves using the hydro-distillation method. The Bioassay test was performed by the WHO method for the determination of adulticidal activity against mosquitoes and arthropods. Different compounds were identified by gas chromatography -mass spectrometry analysis. The LC50 value of the oil was 0.56 mg cm -2 whereas the value of the LC95 was 0.96 mg cm -2 on Drosophila melanogaster. The yield of leaf essential oil obtained by hydro-distillation was 0.022% w/w. Gas chromatography-mass spectrometry analysis of the essential oil showed 66 peaks, where Germacren D (19.29%), B-Caryophyllene (14.55%), α-Humulene (9.51%), Biciclogermacren (8.94%), Germacren B (7.26%) and Terpinene (5.62%) were present in greater amounts and contributed 5...
