BackgroundCoffee bean weevil (Araecerus fasciculatusDeGeer) (Coleoptera: Anthribidae) infestation is a major challenge affecting processed, dried, and stored foods globally. However, the growth performance of this insect pest in processed and stored cassava, plantain, yam, and cocoyam is poorly understood. Resolving this will guide future biotechnological efforts on these food products. In the study, the susceptibility rate of the processed and stored product of cassava, yam, cocoyam, and plantain to the growth performance of the coffee bean weevil at laboratory conditions (20 ± 5 °C and 70 ± 5% R.H.) was investigated. The anti-nutritional (phytate, alkaloids, saponin, tannin, and oxalate) contents of this stored food were used to characterize the survival rate ofA. fasciculatus.The study was carried out for 6 months between December 2012 and May 2013.ResultsResults show that the adult longevity, growth, and feeding of the adultA. fasciculatusdecrease in order from Cassava, Plantain, Yam to Cocoyam. Cocoyam has the highest tannin, alkaloid, and phytate values, which are possible factors that inhibited the growth of the larvae, pupae, and adults’A. fasciculatus. The highest weight loss occurred in cassava followed by plantain. The anti-nutritional factors determine the hatchability of theA. fasciculatuseggs and throughout its development stages. This study revealed that processed and stored products (e.g., cocoyam) with high anti-nutritional factors can surviveA. fasciculatusunder prolonged storage.ConclusionsFrom this study, it is observed that high anti-nutritional compounds in the stored food products inhibit the growth ofAraecerus fasciculatus, especially in cocoyam. The result is important in food security and management in developing countries where food insecurity has become a major challenge.
