Damage to sweetpotato storage roots by insect pests, even when it occurs before harvest, can be considered a post-harvest problem. It reduces both the nutritional and economic value of the storage roots thus reducing the shelf life. This chapter describes the insect pests that damage these storage roots. Additionally, two methods for assessing cultivars for pathogen susceptibility have been introduced.
