“…The inhibition of fertility was due to the action of alkaloids, flavonoids and tannins, substances that inhibit digestion or reproduction of insects. Similar results were reported by Saxena (1989), Strebler (1989), Abbasi et al (2003), Kellouche and Soltani (2004), Seri-Kouassi et al (2004), Thiaw (2008).…”

In preparation for designing a strategy of integrated management associated with post-harvest products in Senegal, the bioactivity of crude and extracts of Calotropis procera Ait. on the survival of eggs and adults Caryedon serratus (Ol.) pest of groundnut, Arachis hypogaea L., was studied under controlled conditions. The crude extracts (ether and methanol) and fractions of extract (hexane, ethyl acetate and methanol) were applied through contact with C. serratus at different concentrations C 1 (0.1 g of dry residue / ml of solvent dilution), C 2 (0.01 g/ml) and C 3 (0.001 g/ml). The action of each biocid extract of C. procera on the survival of treated is dependent on the concentration and varies with the polarity of the extract. All concentrations induce high mortality of C. serratus eggs and adults regardless of the sample in use. The most important (86.14 ± 4.21%) adulticidal action was noted in 10 days of treatment with the methanol fraction. The adulticidal effect of crude methanol extract on C. serratus was in the range of 74.10 ± 2.82%. The biological activity of extracts of C. procera on the insect is also expressed by an imbalance of sex-ratio in favor of males, an extension or a reduction in the duration of the phases of development, reduced fecundity and fertility limited. The fecundity averages, less important, were obtained with the hexane fraction (44.83 ± 3.01 eggs) and high concentrations of ethyl acetate fraction (35 ± 0.71 eggs) or a respective rate of reduction of spawning 52.93% and 63.25% compared to the control. After characterization of reactions, it is clear from this study that the bioactivity of extracts of C. procera is likely related to suspected active compounds (alkaloids, flavonoids, tannins, anthracene derivatives, saponins, sterols and terpenes) as revealed from staining or precipitation using specific reagents.

“…L'importante réduction de croissance du champignon (> 75 %) par les huiles essentielles de Melaleuca quinquenervia aux fortes concentrations (7 000 et 10 000 ppm) pourrait également être attribuée à leurs constituants terpéniques ; (11,9 %) et viridiflorol qui en sont les composantes principales [21]. Il en est de même pour les extraits d'Eucalyptus platyphylla dont l'activité est semblable à celle de Melaleuca quinquenervia aux mêmes teneurs, et dont les composés majoritaires sont le limonène (26,42 %), le 1,8-cinéole (20,04 %), le gamma-terpinène (18,91 %).…”

La présente étude a été conduite dans le but de déterminer et de comparer l'activité antifongique de deux huiles essentielles issues de Melaleuca quinquenervia L. et Eucalyptus platyphylla F. Muell. à celle de deux fongicides de synthèse (le tébuconazole et la spiroxamine) sur Deightoniella torulosa (Syd.) Ellis, un champignon de la phyllosphère des bananiers et bananiers plantains cultivés en Côte-d'Ivoire. Ces huiles ont été additionnées au milieu de culture du champignon (PDA) à différentes concentrations. Elles se sont montrées toxiques sur le champignon en réduisant considérablement la croissance mycélienne et en inhibant la production de spores respectivement aux doses de 7 000 et 10 000 ppm. Les produits de synthèse ont eu une activité élevée en fonction des concentrations utilisées. Ils sont hautement toxiques pour Deightoniella torulosa avec des CI 50 largement inférieures à celles des huiles essentielles. Les huiles essentielles peuvent constituer un moyen de lutte biologique efficace contre Deightoniella torulosa.

Ellis, a fungus of banana leaves by application of Eucalyptus platyphylla F. Muell. and Melaleuca quinquenervia L. essential oils Abstract: The present study was to determine and compare in vitro the antifungal activity of two essential oils from Melaleuca quinquenervia L. and Eucalyptus platyphylla F. Muell. with those of two synthetic fungicides (tebuconazole and spiroxamine) on Deightoniella torulosa (Syd.) Ellis, a pathogenic fungus of bananas and plantains in Côte-d'Ivoire. These oils were added to PDA medium at various concentrations. They showed a toxic activity by reducing considerably the mycelia growth and by inhibiting the production of spore respectively at 7,000 and 10,000 ppm. The synthetic fungicides had a high activity according to their concentrations. They are highly toxic on Deightoniella torulosa with IC 50 widely lower than those of essential oils. Thus, essential oils can be an effective biological product to control Deightoniella torulosa.

“…In Côte d'Ivoire, few data are available regarding the evaluation of antifungal potency of the essential oil while some previous studies have shown, at plants in the Ivorian pharmacopoeia promising virtues (Oussou et al, 2004;Seri-Kouassi et al, 2004). The objective of the study was to evaluate the antifungal activity of the essential oil extracted from Lippia multiflora, plant of pharmacopoeia of Côte d'Ivoire.…”

The objective of this study was to evaluate the antifungal potency of the essential oil of tea of savanna (Lippia multiflora) on three fungal strains. The essential oil is extracted of Lippia multiflora by steam distillation and the antifungal activity in vitro was investigated on Apergillus flavus, Asperguillus Niger and Fusarium sp species. This activity was realized by incorporation of the plant extract in Sabouraud medium prepared by a double dilution. The study revealed a sensitivity of these three species to the essential oil extracted from Lippia multiflora. It has been observed, in a descending order of sensitivity, a minimum fungicidal concentration (MFC) of 2.08 ± 0.58 µl / ml with Aspergillus flavus; 4.16 ± 1.17 µl / ml with Aspergillus Niger and 8.33 ± 2.35 µl / ml with Fusarium sp. The antifungal potency of the essential oil extracted from Lippia multiflora, allows considering its use as a novel approach in the field of integrated management of cereal stocks in post-harvest.
