“…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.

“…Bambara groundnut it is cultivated throughout the north of Cameroon, and it is one of under valorized legumes. Dne of the main reasons for the low quantity of Bambara groundnuts in the consumer basket is the important loss observed in the culture and especially during postharvest storage (Kellouche & Soltan, 2004;Ayamdoo et al, 2013). Insects are major pests which qualitatively and quantitatively degrade these seeds during storage (Costa et al, 2006 Give the diversity of its varieties, chemical and food compositions depend greatly.…”

The storage susceptibility of Bambara groundnut (B. G.) (Voandzeia Subterranean (L.) Thouars) to Callosobruchus maculatus and chemical and functional properties of 11 varieties form Far-North of Cameroon were investigate using standard analytical methods. Storage susceptibility shown that, after five months within treatment, C. maculatus destroy 10 to 50% of grains. The chemical characteristics of none attack grains of 11 varieties were range to 18.64 at 21.08%, 6.85 at 7.44%, 49.75 at 52.68% and to 6.05 at 7.55% respectively for protein, fat, starch and free carbohydrate. These chemical characteristics significantly (p < 0.05) decreases form attacks varieties. For the functional parameters, the none attacks grains was range of 130 at 135%, 19.15 at 20.91%, 18.20 at 21.13%, 2.76 at 3.21% and of 8.54 at 10.14% respectively for water capacity absorption, solubility index, gel length, ash and humidity. The results of this study indicated that storage susceptibility, chemical and functional properties of B. G. be dependant to the varieties.

“…Vis-à-vis des adultes de C. serratus, il n'est pas non plus impossible que les insectes traités avec les produits biocides soient morts par inanition consécutive à des effets répulsifs ou antiappètent comme dans le cas d'autres invertébrés (Tang et al, 2000). Kellouche et Soltani (2004) rapportent que Syzygiumaromaticum et Ficus carica ont une action ovicide, soit en diminuant l'adhésivité des oeufs sur le tégument des graines, ou bien en agissant sur l'embryon après pénétration à travers le chorion. Ils signalent également que les substances présentes dans les poudres de ces deux plantes pourraient être responsables de l'effet ovicide.…”

RESUMEDans la perspective de concevoir une stratégie de protection intégrée des nuisibles associés aux produits post-récolte au Sénégal, la bioactivité des extraits et huile essentielle de Senna occidentalis L. sur les oeufs et adultes de Caryedon serratus (Ol.), a été étudiée. Les extraits bruts (éthéré et méthanolique) et fractions d'extrait (hexane, acétate d'éthyle, méthanol) ont été appliqués sur l'insecteà 0,1 ; 0,01 et 0,001 g/ml. Les principaux résultats révèlent que S. occidentalis L. affectent significativement la survie des stades traités, selon sa concentration et sa polarité. L'extrait éthéré et la fraction hexanique provoquent 79,17% de mortalité embryonnaire en C 1 , tandis que la fraction méthanolique tue 39,58% des oeufs en C 1 . Les produits polaires (extrait et fraction méthanoliques) provoquent respectivement 69,92 ± 2,87% et 72,01 ± 6,86%de mortalités d'adulte. Par contre, ceux apolaires (éthéré et hexanique) tuent respectivement en moyenne 30,41 ± 1,74% et 27,9 ± 0,34% des adultes. L'activité adulticide de l'huile essentielle augmente avec la concentration (91,67% pour 3 ml/l et 30,56% pour 1 ml/l). Cette bioactivité s'exprime aussi par un déséquilibre du sex-ratio en faveur de mâles, une modification du cycle de développement, une fécondité réduite de 67,2% pour la fraction acétate et une fertilité limitée.
