Integrated Pest Management of the Yam Chip Beetle Dinoderus porcellus Lesne (Coleoptera: Bostrichidae): Current Status and Future Prospects

Abstract

In West Africa, Dinoderus porcellus Lesne (Coleoptera: Bostrichidae) is a pest that attacks and spoils stored yam chips. Despite this fact, very little attention has been given to this pest, which could destroy up to 65% of stocks. In order to prevent any damages, farmers are widely using chemical substances for fighting against this pest despite their negative impacts on human health and environment. This chapter aims at proposing a solution approach and discussing the development of an integrated pest management strategy. The solution approach includes storage bags, varietal resistance, botanicals, and biological control. Further research should be done on the use of hermetic bags, essential oils, entomopathogens, insect growth regulators, pheromones, and their combined effects in the D. porcellus control.
