“…The findings of the present investigation are in accordance with those of other workers who have previously reported that plant material affected significantly the development of bruchids (Adedire and Akinneye, 2004;Rahman and Talukder, 2006;Shukla et al, 2007;Bamaryi et al, 2007;Seck et al, 1993;Doumma et al, 2006;Toufique et al, 2009).…”

In this study, we examined the toxicity and persistence of ground fresh leaves of B. senegalensis on the development of Callosobruchus maculatus, major insect pest of cowpea (V. unguiculata) in the sahelian area. The effect of the product has been evaluated over the three developmental stages (egg, larvae and adult) of C. maculatus. At high concentration (4 g/l of ground leaves), 100 % of adults were killed within 24 h of exposure to the leaf extract, and the development of newly laid eggs and neonate larvae was also inhibited. However, the ground leaves of B. senegalensis have a variable efficacy against the bruchid instars larva. The 2nd larvae stage (L2) of C. maculatus developing inside the seeds have proved to be highly susceptible while the 4th larval stage was relatively tolerant. The study of the toxicity persistence of the leaves of B. senegalensis showed that whatever its concentration, the efficacy of crushed leaves of B. senegalensis decreased with the storage time. At a concentration of 20 g/l, the effect of B. seneglensis can persist up to 7 days.

“…The insecticidal properties of these two sulphur-containing compounds are well known and their use for pest control in storage systems has been suggested (Seck et al 1993(Seck et al , 1996Auger et al 1994;Thibout and Auger 1997). However, these studies did not analyze the susceptibility of the parasitoids developing in the stores to these sulphur-containing compounds.…”

“…In Caryedon serratus, the use of products derived from plants repellent or insecticide lags behind other weevils such as Callosobruchus maculatus F.

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.
