“…This valuable component may be present in only low concentrations (< 1 %), or even trace amounts, in the essential oils of E. citriodora, and therefore would need to be synthesized 12 . In the present study, we have shown that plants grown under shaded conditions produced record amounts of (±)-p-Menthane-3,8-diol (3.93-4.66 %), whereas those grown under 'full sun' produced significantly lower amounts (0.67 %) and in only some of the plants.…”

“…E. citriodora is grown extensively worldwide, mainly for the paper and wood industries, and to a lesser degree for its leaf essential oils. The essential oils are produced commercially mainly in China, India and Brazil 1 , and are mostly used for perfumes or medicines as pain reliever 2,3 , antifungal 4,5 , allelopathic [6][7][8][9][10][11] , insect repellent agent [12][13][14][15][16] and recently as biomass feedstock for production of biofuels 17,18 . The leaf-essential oils of E. citriodora includes nearly 100 volatile compounds 1,19 , all contributing to the final lemony, rose-like odor.…”

The influence of light conditions on plant growth and essential oil production of the novel herb Eucalyptus citriodora (Lemon-Scented Gum) was investigated. Pot-grown plants were grown either directly exposed to sunlight or 'shaded' with the least exposure to sunlight (75 % shade) or with intermediate exposure to sunlight (50 % shade). Shaded plants were generally taller, had thicker stems and wider canopies, grew more branches, produced larger leaves, produced more essential oils per plant, produced similar concentrations of the major essential oil components (citronellal, β-citronellol and trans-caryophyllene) in the leaves and produced record high concentrations of (±)-p-menthane-3,8-diol, a component having superior insect repellent properties, than the ones grown under full sun. Plants grown under '50% shade' were likely to be the most productive of leaves and essential oils, either for personal use in tea infusions or for production of leaf-essential oils, potentially having improved capacity for insect repellency.

“…PMD (para-menthane 3, 8 diol) as a repellant has a lower vapour pressure than volatile monoterpenes found in most plant oils [37] it provides very high protection from a broad range of insect vectors for several hours [36] and has a proven safety to human health.…”

En este trabajo nos trazamos como objetivo evaluar la actividad repelente de diferentes formulaciones del aceite de Melaleuca quinquinervia Cav S.T. Blake en condiciones de laboratorio y terreno. Se prepararon formulaciones etanólicas, hidroalcohólicas, hidrofíli-cas y en base oleosa con aceite mineral y dipropilenglicol. Se trató el antebrazo con 1 ml de repelente y la mano fue cubierta con un guante de goma. El antebrazo fue expuesto por 3 minutos cada media hora. Se obtuvo una tendencia positiva del tiempo de protección con el aumento de la concentración. El mayor tiempo de protección observado (5 horas) fue con la cepa Santa Clara y la formulación de aceite al 20 % en dipropilenglicol Con estos resultados se evaluó en condiciones de terreno obteniéndose tiempos de protección promedio de hora y media. El repelente formulado con dipropilenglicol y aceite de Melaleuca quinquinervia al 20% es adecuado para las labores del personal dedicado a la protección de bosques y costas.Palabras clave: Aceite esencial, repelente, Aedes aegypti. Abstract Repellent activity of essential oils formulations from Melaleuca quinquenervia (Cav.) S.T. Blake (Myrtales: Myrtaceae) on mosquitoesThe study was carried out in order to evaluate the repellent activity of different formulations of Melaleuca quinquinervia Cav ST Blake oil, in laboratory and field conditions. Ethanolic, hydroalcoholic, and hydrophilic formulations were prepared in mineral oil and dipropylene glycol. In laboratory experiments the forearm was treated with 1ml of the repellent, and exposed against different Aedes aegypti strains by 3 minutes every half hour. The hand was protected or covered with a rubber glove. A positive protection trend was observed when the concentrations of the different formulations were increasing. The higher protection was observed (5 hours) in Aedes aegypti Santa Clara strain with 20% dipropyleneglycol oil formulations. These laboratory results were evaluated then in field conditions, obtaining average protection times of 1 ½ hours.
