| description | Plectranthus amboinicus (Lour.) Spreng is an herbaceous and aromatic plant that belongs to the Lamiaceae family. In this research work, the repellent and insecticidal activity of the essential oil (EO) of P. amboinicus from the Condoto township in the department of Choco (Colombia) against the flour weevil Tribolium castaneum (Herbst) was studied. EO was isolated by the hydrodistillation technique. The identification of the volatile metabolites of P. amboinicus EO was done through gas chromatography coupled to mass spectrometry (GC / MS). The contact method was used for the bioassay of the essential oil’s repellent and fumigant activities. In the Plectranthus amboinicus EO, fifteen compounds were found. The major compound was carvacrol (75.9%) followed by α-bergamotene, p-cymene, α-humulene, 4-terpineol, caryophyllene oxide, β-guaiene, 1-octen-3-ol, α-muurolene, caryophyllene, 3-hexen-2-ol, γ-terpinene, isothymol, 2-carene and β-bisabolene, respectively. The highest repellent activity obtained was 83.33 and 9.67% at a concentration of 0,1% with exposure times of 2 and 4 hours, respectively. The fumigant activity was 100% at a concentration of EO 250 μL L-1. The results indicated that the natural compounds tested may be useful alternatives to control T. castaneum infestation. |

Plectranthus amboinicus (Lour.) Spreng es una planta herbácea y aromática, pertenece a la familia de las Lamiaceae. En este trabajo de investigación se estudió la actividad repelente e insecticida del aceite esencial (AE) de P. amboinicus proveniente de Condoto corregimiento del departamento de Chocó (Colombia) contra el gorgojo de harina Tribolium castaneum Herbst. El AE se aisló mediante la técnica de hidrodestilación. La identificación de los metabolitos volátiles del AE de P. amboinicus, se hizo a través de cromatografía de gases acoplada a espectrometría de a masas (CG/MS). Para el bioensayo de la actividad repelente y fumigante del aceite esencial fue utilizado el método de contacto. En el AE de Plectranthus amboinicus, se encontraron 15 compuestos mayoritarios. Entre ellos están: 3-hexen-2-ol-(z), 3-hexen-2-ol-(z), 2-careno, p-cimeno, γ-terpineno, 4-terpineol, carvacrol, isotimol, β-Guaieno, α-Bergamoteno, humuleno, α-muuroleno y β-bisaboleno. La actividad repente más alta fue de 83.33 y 92.67% a una concentración de 0.1% con tiempos de exposición de 2 y 4 horas, respectivamente. La actividad fumigante fue de 100% a la concentración del EO de 250 μL L-1. Los resultados indicaron que los compuestos naturales probados pueden ser alternativas útiles para controlar la infestación de T. castaneum.
