“…Según la escala de Juliana y Su (1983), el poder repelente del saúco es muy bajo, no mayor al nivel II (Tapondjou et al, 2005). En general, en nuestro estudio los extractos no tuvieron efectos repelentes significativos contra el gorgojo del maíz, a pesar que el 75% de los tratamientos en Pinto et al (2016) presentó un índice de repelencia < 1. Silva et al (2003) recomiendan voltear una vez al mes los envases de almacenamiento para homogeneizar el polvo entre los granos de maíz y favorecer el control del gorgojo del maíz.…”

RESUMENEl uso de extractos de plantas con propiedades insecticidas es una alternativa al uso de agroquímicos sintéticos. Se evaluó el efecto tóxico del saúco, Sambucus peruviana Kuhnt (Caprifoliaceae), en el crustáceo pulga de agua, Daphnia magna Straus (Cladocera, Daphniidae) y la microavispa Copidosoma koehleri Blanchard (Hym.: Encyrtidae). La hoja, corteza y raíz de saúco se evaluaron en maceración en agua, cocción, infusión y maceración en alcohol etílico. También se evaluó el efecto del polvo de corteza en el gorgojo del maíz, Sitophilus zeamais (Motschulsky) (Col.: Curculionidae). Los mayores efectos de toxicidad para D. magna se produjeron con la infusión de hojas. Los adultos de C. koehleri fueron más sensibles a la infusión de raíces. La emergencia de las microavispas adultas disminuyó con la cocción de hojas. Los estados larvarios y pupas no emergidos fueron afectados por la cocción y maceración de hojas. También se observó repelencia, de mayor nivel con la maceración en alcohol etílico de hojas y raíces. El polvo de corteza causó mortalidad en S. zeamais. También hubo efectos de la maceración, cocción e infusión de la corteza en el porcentaje de granos dañados, los que perdieron < del 3% de su peso. El efecto insecticida y repelente del polvo y la cocción de la corteza de S. peruviana es importante por su efecto en S. zeamais, pero no así las hojas y raíces, por sus efectos negativos en el ambiente acuático de D. magna y en el control biológico por C. koehleri.Palabras clave: Grano almacenado, efecto insecticida, efecto repelente, insecticida botánico. ABSTRACT Some extracts of plants with insecticidal properties are used on pest control as an alternative to synthetic agrochemicals. The objective of this study was to evaluate the toxic effect of Peruvian elderberry, Sambucus peruviana Kuhnt (Caprifoliaceae), on the water flea Daphnia magna Straus, the maize weevil Sitophilus zeamais (Motschulsky) (Col.: Curculionidae), and the microhymenopteranCopidosoma koehleri Blanchard (Hym.: Encyrtidae). Plant leaves, bark, and roots were treated by maceration in water, boiling, infusion and maceration in ethyl alcohol. The insecticidal activity of root and bark powders against Sitophilus zeamais was also evaluated. The highest repellent activity against D. magna was observed with the use of leaf infusion. Adults of C. koehleri were more sensitive to root infusion. Adult emergence of this parasitoid decreased with leaves macerated in water. Larvae and pupae did not emerge with leaf treatments by maceration and boiling. Higher levels of repellency were observed with leaves and roots treated by maceration in ethyl alcohol.Chilean J. Agric. Anim. Sci., ex Agro-Ciencia (2017) 33(1): 4 3-13.Bark powder caused mortality of S. zeamais. Bark treated by maceration, boiling, and as an infusion also had effects on the percentage of damaged grains, resulting in a < 3% weight loss. It can be concluded that unlike S. peruviana leaves and roots, both powder and boiled bark have insecticidal and repellent effects against S. zeama...

“…Its leaves and bark are used in traditional medicine to treat liver diseases and rheumatism [10]. The essential oil prepared by the distillation of peumo showed activity against Nosema ceranae, the originator of nosemosis in honeybee [11]; against insect Sitophilus zeamais Motschulsky, known as a maize weevil, causing significant loses during cereals' storage [12]; and against Musca domestica L. [13]. Moreover, the leaves extract demonstrated a protective effect against ethyl methane sulphonate-induced mutagenesis in Drosophila melanogaster [14].…”

Antimicrobial Activity of Extracts of Two Native Fruits of Chile: Arrayan (Luma apiculata) and Peumo (Cryptocarya alba)

Arrayan and peumo fruits are commonly used in the traditional medicine of Chile. In this study, the concentration of the extracts halving the bacterial viability and biofilms formation and disruption of the drug-sensitive and drug-resistant strains of Staphylococcus aureus and Pseudomonas aeruginosa was determined. The chemical composition of extracts was analyzed by high-resolution liquid chromatography coupled with mass spectrometry (U-HPLC/MS). The arrayan extract (Inhibitory concentration IC50 0.35 ± 0.01 mg/mL) was more effective than peumo extract (IC50 0.53 ± 0.02 mg/mL) in the inhibition of S. aureus planktonic cells. Similarly, the arrayan extract was more effective in inhibiting the adhesion (S. aureus IC50 0.23 ± 0.02 mg/mL, P. aeruginosa IC50 0.29 ± 0.02 mg/mL) than peumo extracts (S. aureus IC50 0.47 ± 0.03 mg/mL, P. aeruginosa IC50 0.35 ± 0.01 mg/mL). Both extracts inhibited quorum sensing in a concentration-dependent manner, and the most significant was the autoinducer-2 type communication inhibition by arrayan extract. Both extracts also disrupted preformed biofilm of P. aeruginosa (arrayan IC50 0.56 ± 0.04 mg/mL, peumo IC50 0.59 ± 0.04 mg/mL). However, neither arrayan nor peumo extracts disrupted S. aureus mature biofilm. U-HPLC/MS showed that both fruit extracts mainly possessed quercetin compounds; the peumo fruit extract also contained phenolic acids and phenylpropanoids. Our results suggested that both extracts could be used as natural antimicrobials for some skin and nosocomial infections.

“…Previous studies have demonstrated strong insecticidal action of essential oils against adult Sitophilus zeamais. [15][16][17][18] Among the components of essential oils, the benzene derivatives have revealed high insecticidal and repellent action. 19,20 Different factors could be related to the toxic action of phenylpropanoids, such as the distance of the double bond in the side chain in respect to the aromatic ring; 20 LogP values and their relation with cuticular penetration; the polarizability of the molecule; the presence of carbonyl groups and their interactions with the GABA receptor; and the inhibition of AChE activity.…”
