Interpretive Summary: Once cereal grains ire harvested and put into storage they provide a resource for a range of insect pests of stored grain. With the exceptions of Sitophilus zeamais (Motschulsky) (the maize weevil), Prostephanus trunctatus (Horn) (the larger grain borer), Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) (the Angoumois grain moth), these insects rarely attack grain in the field before harvest, but once grain is in storage insect infestation may occur. Insects can be carried into storage via infested harvesters or other machinery, and infested grain can be moved from storage to storage during the postharvest handling of grain. Even without human help, field studies have demonstrated the importance of flight in some species, and so flying insects represent another source of infestation. This means that methods are needed to either disinfest grain or to protect it from infestation during storage. The aim of this chapter is to review recent advances in insect pest management in stored grain, focusing primarily on research published in the last 10 years on chemical and non-chemical methods, ranging from methods that are well established to those that are still being evaluated. As many papers have been published on this broad topic, sometimes we cite only a few papers from the many published to illustrate particular recent advances.

Technical Abstract: Stored grain is vulnerable to attach by a variety of insect pests, that can generally be classified as external or internal feeders. Infestations primarily occur after grain is stored, though there is some evidence that infestations can occur in the field right before harvest. There are a variety of pest management strategies that can be used to protect or disinfest stored grains, including chemical and non-chemical methods. In this chapter, we review recent advances in the field of stored product entomology regarding management of stored grains, with emphasis on advances that have occurred during the last decade.
