“…Capsicum frutescens powder and extract were especially quick and effective, reducing oviposition, hatchability and suppressing adult emergence. These observed activities may be its pungency, attributed to the presence of capsacin (Miyakado et al, 1979;Oni 2011;Ashamo & Akinnawo, 2012). The powder and oil of A. occidentales was also very toxic to the survival of S. cerealella: no adults emergedfrom eggs treated with oil.…”

Powders and extracts prepared from Capsicum frutescens, Cymbopogon citratus, Moringa oleifera, Anacardium occidentale were tested for their insecticidal potential against Angoumois grain moth, Sitotroga cerealella. The powder of C. frutescens had the highest mortality rate of 100% after 2 days of application at all tested concentrations. The extracts killed all the adult moths introduced at all tested concentrations. The survival of the moth from egg to adult when treated with the plant powders showed significantly greater mortality. Extracts of all the tested plants were toxic to adult moths and also prevent hatching of the eggs of S. cerealella..

Powders and extracts prepared from part and products of four plants species indigenous to Nigeria were tested under laboratory condition at 28 ± 2°C and 75 ± 5% relative humidity for their insecticidal potential against Angoumois grain moth, Sitotroga cerealella. Adult S. cerealella were exposed to three concentrations at rate 0.5, 1 and 2 g of Capsicum frutescens, Cymbopogon citratus, Moringa oleifera and Anacardium occidentale powders and extracts at the rate of 1, 2 and 3%/ 20 g of wheat grains. Parameters evaluated were adult moth mortality, adult emergence and % hatchability in treated wheat grains after infestation. Results show that significant differences ( p < 0.05) existed among the powders and the concentrations. The powder of C. frutescens had the highest mortality rate of 100% after two days of application at all tested concentrations. There were no adult emergence of moth in samples treated with C. frutescens and A. occidentale powders. The extracts completely killed all the adult moths introduced at all tested concentrations. The survival of the moth from egg to adult when treated with the plant powders showed that there was significantly ( p < 0.05) more adult in the control (71.3) compared to others. Extracts of all the tested plants were toxic to adult moth and also prevent hatching of the eggs of S. cerealella.

Five varieties of Nigerian long pepper (Capsicum frutescens) fruits (var. baccatum, chacoense, fingerh, maxima and minima) were studied for their antibacterial activities. Methods described by Association of Official Analytical Chemists (AOAC) were employed to determine the phytochemicals in the pepper fruits. The Capsicum frutescens fruits showed antibacterial activity (10.33 -32.66 mm zones of inhibition) against all the tested pathogenic bacteria. The minimum inhibitory concentrations for the peppers range between 7.8 and 37.5 mg/ml. Pepper var. minima had the highest MIC (37.5 mg/ml) while pepper var. fingerh exhibited the lowest MIC (7.8 mg/ml) against Pseudomonas aeruginosa and Salmonella typhi, respectively. The flavonoids, tannins, alkaloids and saponins found present in the extracts were quantified as 0. 0019-0.0043, 0.0084-0.0146, 6.57-15.78 and 15.67-26.29 mg/ml, respectively. From this study, it was concluded that the long peppers have antibacterial effect on the tested food borne pathogens; even the less pungent C. frutescens var. fingerh showed antibacterial activity. These peppers when consumed raw could prevent elaboration of infection that the test pathogenic bacteria could cause if consumed in foods.
